Description
Description Description
[0001] La presente invention concerne un materiau composite de revetement de surface ainsi que son procede de realisation. The present invention relates to a composite surface coating material and its method of production.
[0002] L'expression „revetement de surface" designe ici tous les types de surface, verticale, horizontale ou inclinee, que la surface soit en exterieur ou en interieur, quel que soit le materiau constitutif de la surface et/ou sa destination. A titre d'exemples non limitatifs, on peut eiter de parois de bätiments, des toits plats, des terrasses, des aires de jeux, des parkings, des cours, des sols de bätiments industriels ou commerciaux, des aires de stockage. De tels revetements sont employes comme isolant phonique et/ou thermique et/ou comme element decoratif. Ces revetements forment une surface de roulage ou de marche lorsqu'ils sont poses sur un sol ou toute autre surface servant ä un deplacement. [0002] The expression “surface coating” designates here all types of surface, vertical, horizontal or inclined, whether the surface is exterior or interior, whatever the material constituting the surface and/or its destination. By way of non-limiting examples, it is possible to mention the walls of buildings, flat roofs, terraces, playgrounds, car parks, courtyards, floors of industrial or commercial buildings, storage areas. are used as sound and/or heat insulation and/or as a decorative element These coverings form a rolling or walking surface when they are placed on a floor or any other surface used for movement.
[0003] De tels revetements ne forment pas, en general, un element structurel de la surface sur laquelle ils sont fixes. Aussi, le materiau constitutif de ces revetements doit etre leger et neutre vis ä vis du materiau constitutif de la surface sur laquelle ils sont fixes. De ce fait, il a ete envisage de realiser des revetements composites comportant une Charge minerale assurant la resistance mecanique et une partie en polymeres conferant souplesse et proprietes isolantes au revetement. [0003] Such coatings do not generally form a structural element of the surface on which they are fixed. Also, the constituent material of these coatings must be light and neutral with respect to the constituent material of the surface on which they are fixed. As a result, it was envisaged to produce composite coatings comprising a mineral filler providing mechanical resistance and a part in polymers conferring flexibility and insulating properties on the coating.
[0004] FR-A-2 831 173 enseigne un produit composite ä base de dechets de matieres plastiques, avec un liant et comportant une Charge minerale. Concernant la partie non minerale, le composite comprend des resines thermoplastiques broyees, du caoutchouc recycle tel que de la poudrette de pneu et, en Charge minerale, le produit peut comprendre des poudres fines ou grossieres comme de la pouzzolane. D'autres elements de Charge non minerale peuvent etre ajoutes au materiau composite Ici, le materiau composite est utilise comme isolant thermique, electrique et phonique. Ce materiau est base sur une composition variable, avec de nombreux composants d'origine et de nature diverses, ce qui ne permet pas d'optimiser les caracteristiques et l'homogeneite du materiau final. [0004] FR-A-2 831 173 teaches a composite product based on waste plastic materials, with a binder and comprising a mineral filler. Regarding the non-mineral part, the composite comprises ground thermoplastic resins, recycled rubber such as tire crumb and, in mineral filler, the product may comprise fine or coarse powders such as pozzolan. Other non-mineral filler elements can be added to the composite material Here, the composite material is used as thermal, electrical and sound insulation. This material is based on a variable composition, with numerous components of various origins and natures, which does not make it possible to optimize the characteristics and the homogeneity of the final material.
[0005] WO-A-2007/070968 decrit un materiau composite ä base de caoutchouc utilisable comme revetement de surface.Le materiau comprend du bitume, du caoutchouc issu par exemple de dechets de pneus, un composant d'allegement tel que du polystyrene, un liant et, si besoin, une Charge minerale qui peut etre de la pouzzolane. Un tel materiau est de formulation complexe et, de facto, constitue un derive du bitume. Ce produit issu directement du raffinage petrolier est connu pour induire des risques sur la sante des personnes le mettant en oeuvre. [0005] WO-A-2007/070968 describes a rubber-based composite material that can be used as a surface covering. a binder and, if necessary, a mineral filler which may be pozzolan. Such a material is of complex formulation and, de facto, constitutes a derivative of bitumen. This product resulting directly from oil refining is known to induce risks on the health of the people implementing it.
[0006] Actuellement, les pneus usages doivent etre recycles. Ils sont utilises, ä titre d'exemples non limitatifs, comme combustible, materiau de remblai en voirie, pour realiser des murs de soutenement, pour faire des protections industrielles, des amortisseurs de choc sur des vehicules, des surfaces de jeu sur des terrains de sport, des caillebottis et tapis de sol pour usage agricole ou industriel. Dans la majorite des cas, le produit recycle est essentiellement ä base de caoutchouc d'oü des caracteristiques du produit qui restent tres similaires ä celles du caoutchouc, voire du pneu, initial. De plus la quantite importante de caoutchouc provenant de pneu peut induire des desagrements tels que l'odeur qui en limitent son usage, par exemple pour des surfaces de jeu, et une impermeabilite importante ä l'eau, ce qui induit des proprietes drainantes limitees au revetement en un tel materiau. Dans certains cas, cela peut etre un avantage mais pour des revetements de sol en exterieur, cela est un inconvenient. [0006] Currently, used tires must be recycled. They are used, by way of non-limiting examples, as fuel, fill material on roads, to make retaining walls, to make industrial protection, shock absorbers on vehicles, playing surfaces on sport, gratings and floor mats for agricultural or industrial use. In the majority of cases, the recycled product is essentially based on rubber, hence the characteristics of the product which remain very similar to those of the initial rubber, or even of the tyre. In addition, the large amount of rubber from tires can induce inconveniences such as odor which limit its use, for example for playing surfaces, and significant impermeability to water, which induces drainage properties limited to the covering in such a material. In some cases this can be an advantage but for exterior flooring it is a disadvantage.
[0007] L'invention a pour objet de proposer un materiau composite de revetement de surface qui permette un recyclage maximum de caoutchouc provenant de pneus, simple ä realiser et presentant des proprietes drainantes tout en conservant des proprietes d'isolation thermique, phonique et en offrant une resistance ä l'abrasion optimale. [0007] The object of the invention is to propose a composite material for surface covering which allows maximum recycling of rubber coming from tires, which is simple to produce and which has draining properties while retaining thermal and sound insulation properties and providing optimum abrasion resistance.
[0008] A cet effet, l'invention a pour objet un materiau composite de revetement de surface comportant au moins des dechets de pneus, une Charge minerale et un liant, les dechets de pneus ayant une granulometrie homogene comprise entre 0 et 7mm, la Charge minerale etant presente sous au moins deux granulometries differentes, caracterisee en ce que la Charge minerale formee par de la pouzzolane de granulometrie connue et homogene represente entre 40% et 80% en mässe du melange avant ajout du liant, les dechets de pneus representant de 60% ä 20%. [0008] To this end, the subject of the invention is a composite material for surface covering comprising at least waste tires, a mineral filler and a binder, the waste tires having a homogeneous particle size between 0 and 7 mm, the Mineral filler being present in at least two different particle sizes, characterized in that the mineral filler formed by pozzolan of known and homogeneous particle size represents between 40% and 80% by mass of the mixture before addition of the binder, the tire waste representing 60% to 20%.
[0009] Le fait que la Charge minerale, formee par la pouzzolane, soit presente selon au moins deux granulometries differentes mais connues et chacune etant homogene permet, sans modifier le ratio general entre les dechets de pneus et la Charge minerale, de renforcer les proprietes drainantes du materiau sans affecter sa resistance mecanique. [0009] The fact that the mineral filler, formed by pozzolan, is present in at least two different but known particle sizes and each being homogeneous makes it possible, without modifying the general ratio between the waste tires and the mineral filler, to reinforce the properties draining of the material without affecting its mechanical resistance.
[0010] Selon des aspects avantageux mais non obligatoires de l'invention, un tel materiau peut comprendre une ou plusieurs des caracteristiques suivantes : [0010] According to advantageous but not mandatory aspects of the invention, such a material may comprise one or more of the following characteristics:
[0011] - Le materiau comprend 70% de pouzzolane avant ajout du liant, les dechets de pneus representant 30%. [0011] The material comprises 70% pozzolan before adding the binder, tire waste representing 30%.
[0012] - Le materiau comprend 50% de pouzzolane avant ajout du liant, les dechets de pneus representant 50%. [0012] The material comprises 50% pozzolan before adding the binder, tire waste representing 50%.
[0013] Les granulometries de la pouzzolane presentes dans le materiau sont au moins de 3 mm ä 6 mm et de 7 mm ä 15 mm, les dechets de pneus ayant une granulometrie de 0,5 mm ä 2,5 mm ou de 3 mm ä 6 mm. [0013] The particle sizes of the pozzolan present in the material are at least 3 mm to 6 mm and 7 mm to 15 mm, the waste tires having a particle size of 0.5 mm to 2.5 mm or 3 mm at 6 mm.
[0014] L'invention concerne egalement un procede de realisation du materiau composite de revetement de surface conforme ä l'une des caracteristiques precedentes, caracterise en ce qu'il comprend au moins les etapes suivantes : [0014] The invention also relates to a process for producing the composite surface coating material conforming to one of the preceding characteristics, characterized in that it comprises at least the following steps:

[0021] - Before step d) of smoothing, elements such as LEDs, sound speakers, transducers, RFID tags, electronic identification chips, GPS chips, metal elements and/or are incorporated into the material. or magnetic, sensors or others.
[0022] L'invention sera mieux comprise et d'autres avantages de celle-ci apparaitront plus clairement ä la lecture de ladescription qui va suivre, donnee uniquement ä titre d'exemple non limitatif et falte en reference au dessin annexe dans lequel: The invention will be better understood and other advantages thereof will appear more clearly on reading the description which follows, given solely by way of non-limiting example and with reference to the appended drawing in which:
[0023] [Fig. 1] est une vue simplifiee, en perspective, d'une partie de surface revetue d'un materiau conforme ä un mode de realisation de l'invention. [0023] [Fig. 1] is a simplified view, in perspective, of a surface part coated with a material according to one embodiment of the invention.
[0024] La figure 1 illustre une partie de surface 1 sur laquelle, en tant que revetement, est pose un materiau 2 conforme ä un mode de realisation de l'invention. La partie de surface 1 illustree ici correspond ä une surface destinee ä permettre le deplacement de personnes, d'animaux ou de vehicules, cela autant en Interieur qu'en exterieur. On trouve de telles surfaces sur des allees de garage, des parkings, des aires de jeux, des cours de bätiments ä usage prive, publique, commercial ou industriel. Dans d'autres modes de realisation, la surface n'est pas destinee ä permettre le deplacement. II s'agit, par exemple, de zones planes, inclinees ou verticales, situees en exterieur ou en interieur et sur lesquelles on souhaite poser un revetement de protection et/ou decoratif. A titre d'exemples non limitatifs, on peut eiter des protections de plantation vegetale ou forestiere, des murs ou plans inclines de bätiments, de mobiliers urbains ou d'ouvrages d'art, des terres pleins, des talus de voies de circulation, des toits terrasses ou autres. Dans tous les cas, quelle que soll la surface sur laquelle on pose le materiau 2, ce dernier est maintenu en position sur la surface 1 par des moyens connus en soi. [0024] Figure 1 illustrates a surface part 1 on which, as a coating, a material 2 according to one embodiment of the invention is laid. The surface part 1 illustrated here corresponds to a surface intended to allow the movement of people, animals or vehicles, both indoors and outdoors. Such surfaces are found on driveways, parking lots, playgrounds, courtyards of buildings for private, public, commercial or industrial use. In other embodiments, the surface is not intended to allow movement. These are, for example, flat, inclined or vertical zones, located outside or inside and on which it is desired to place a protective and/or decorative coating. By way of non-limiting examples, we can mention the protection of plant or forest plantations, walls or inclined planes of buildings, street furniture or works of art, solid land, embankments of traffic lanes, roof terraces or others. In all cases, regardless of the surface on which the material 2 is placed, the latter is held in position on the surface 1 by means known per se.
[0025] Par la suite, il sera decrit, pour faciliter la lecture, un mode de realisation prefere dans lequel le materiau 2 est utilise comme revetement d'une partie de surface 1 destinee au deplacement de personnes et/ou de vehicules. Dans un tel cas, soll le materiau 2 est mis en forme directement sur la partie de surface 1 soll II est preforme, par exemple en dalles carrees qui sont ensuite positionnees sur la partie de surface 1. Dans tous les cas, le materiau est adherent sur la plupart des surfaces rencontrees, par exemple, le beton, le plastique, le bois, la pierre, la ceramique ou une surface naturelle. Ces proprietes d'adhesion facilitent sa mise en place, sans qu'il soit systematiquement necessaire de fixer le materiau par des moyens connus tels que vissage ou collage dans le cas d'une dalle preformee. Le procede d'utilisation du materiau sera decrit ulterieurement. Thereafter, it will be described, to facilitate reading, a preferred embodiment in which the material 2 is used as a coating of a surface part 1 intended for the movement of people and / or vehicles. In such a case, soll the material 2 is shaped directly on the surface part 1 soll II is preformed, for example in square slabs which are then positioned on the surface part 1. In all cases, the material is adherent on most surfaces encountered, for example, concrete, plastic, wood, stone, ceramic or a natural surface. These adhesion properties facilitate its installation, without it being systematically necessary to fix the material by known means such as screwing or gluing in the case of a preformed slab. The method of using the material will be described later.
[0026] Le materiau 2 est un materiau composite comportant au moins trois composants essentiels : des dechets de pneus, une Charge minerale et un liant. The material 2 is a composite material comprising at least three essential components: tire waste, a mineral filler and a binder.
[0027] Les dechets de pneus se presentent sous forme de granulats 3 egalement connus sous les noms de SBR (Styrene Butadiene Rubber) ou de poudrette. Par la suite, pour faciliter la lecture, le terme poudrette sera employe. La poudrette 3 est de granulometrie connue et homogene. La poudrette 3 ne comprend aucun additif et est composee de particules de caoutchouc sechees, avec une densite en vrac voisine de 0,4. Tire waste is in the form of aggregates 3 also known as SBR (Styrene Butadiene Rubber) or crumb. Subsequently, to facilitate reading, the term powder will be used. Powder 3 is of known and homogeneous particle size. Crumb 3 does not include any additive and is composed of dried rubber particles, with a bulk density close to 0.4.
[0028] En Variante, la poudrette 3 comprend egalement du caoutchouc provenant d'autres produits que les pneus, par exemple des bandes de convoyage, des courroies, des sangles, des elements d'amortissement ou tout autre produit en caoutchouc et d'une composition identique, ou au moins similaire, ä celle des pneus. [0028] Alternatively, the crumb 3 also comprises rubber from products other than tires, for example conveyor belts, belts, straps, damping elements or any other rubber product and a composition identical, or at least similar, to that of tires.
[0029] La granulometrie de la poudrette 3 est comprise globalement entre 0 et 7 mm Avantageusement, la poudrette utilisee pour le materiau objet de l'invention est une poudrette beneficiant d'un certificat de conformite garantissant que les pneus ont ete mis sur le marche en repondant ä toutes les exigences en termes d'homologation et que la poudrette a ete obtenue par des procedes mecaniques , sans ajout d'additifs. La poudrette 3 est fournie en trois granulometries correspondant aux besoins principaux du marche. [0029] The particle size of crumb 3 is generally between 0 and 7 mm Advantageously, the crumb used for the material that is the subject of the invention is a crumb benefiting from a certificate of conformity guaranteeing that the tires have been placed on the market. by meeting all the requirements in terms of approval and that the crumb has been obtained by mechanical processes, without the addition of additives. Crumb 3 is supplied in three grain sizes corresponding to the main needs of the market.
[0030] La poudrette 3 de granulometrie la plus fine, comprise entre 0 et 0,8 mm avec une repartition teile que 61% de particules a moins de 0,71 mm. Cette poudrette sera referencee par la suite PnF The crumb 3 of the finest particle size, between 0 and 0.8 mm with a teile distribution that 61% of particles less than 0.71 mm. This crumb will be referenced later PnF
[0031] Une poudrette 3 de granulometrie moyenne, comprise entre 0,5mm et 2,5 mm avec une repartition teile que 77% des particules a moins de 2 mm. Cette poudrette sera referencee par la suite PnM. A crumb 3 of average particle size, between 0.5 mm and 2.5 mm with a teile distribution that 77% of the particles are less than 2 mm. This crumb will be referred to below as PnM.
[0032] Une poudrette 3 de granulometrie elevee, comprise entre 3 mm et 6 mm avec une repartition teile que 87% des particules a moins de 5 mm. Cette poudrette sera referencee par la suite PnG. A crumb 3 of high particle size, between 3 mm and 6 mm with a teile distribution that 87% of the particles are less than 5 mm. This crumb will be referred to below as PnG.
[0033] On congoit que, dans le cadre de l'invention, il est possible d'utiliser d'autres granulometries que celles citees ou plus de trois granulometries, en fonction du revetement final desire et/ou du type de surface ä recouvrir. [0033] It is understood that, within the scope of the invention, it is possible to use other particle sizes than those mentioned or more than three particle sizes, depending on the desired final coating and/or the type of surface to be covered.
[0034] Outre la poudrette 3, le materiau 2 comprend une Charge minerale 4. Avantageusement, la Charge minerale est de la pouzzolane 4. En Variante la Charge minerale est d'autre nature ou complexe, par exemple formee de pouzzolane associee ä d'autres charges minerales comme de la pierre ponce, de la diatomite, du corail mort ou autre. Dans tous les cas, la Charge minerale doit apporter une resistance mecanique sans alourdir le materiau. [0034] In addition to crumb 3, material 2 comprises a mineral filler 4. Advantageously, the mineral filler is pozzolana 4. Alternatively, the mineral filler is of another nature or complex, for example formed of pozzolana associated with other mineral fillers such as pumice, diatomite, dead coral or other. In all cases, the mineral filler must provide mechanical resistance without weighing down the material.
[0035] Pour memoire, la pouzzolane est une röche d'origine volcanique naturelle constituee par des scories volcaniques basaltiques ou de composition proche. Elle possede une structure alveolaire. Elle est connue depuis l'epoque romaine comme constituant d'un mortier durcissant avec le temps et, en particulier, lorsqu'il est en contact avec l'eau de mer. Elle possede un excellent isolant thermique et acoustique et sa capacite d'absorption varie de 20% ä 30% en poids sec. Elle est utilisee, par exemple, en horticulture, en amenagement paysagers comme paillage et/ou pour eviter le compactage des sols, en agriculture pour alleger les sols, les constructions, le beton, dans la composition des ciments, dans le traitement hivernal des routes, pour les sols d'equipements sportifs tels des hippodromes, des pistes d'athletisme, des courts de tennis. La pouzzolane, du fait de sa porosite, constitue un bon support bacterien et un bon filtre. Elle est utilisee ainsi dans l'assainissement non collectif, le traitement des eaux potables, le lagunage, l'aquariophilie. [0035] As a reminder, pozzolan is a rock of natural volcanic origin consisting of basaltic volcanic scoria or of similar composition. It has an alveolar structure. It has been known since Roman times as a constituent of a mortar that hardens over time and, in particular, when it comes into contact with seawater. It has an excellent thermal and acoustic insulation and its ability to absorb varies from 20% to 30% by dry weight. It is used, for example, in horticulture, in landscaping as mulch and/or to avoid soil compaction, in agriculture to lighten the soil, constructions, concrete, in the composition of cements, in the winter treatment of roads , for sports equipment floors such as racetracks, athletics tracks, tennis courts. Pozzolan, because of its porosity, constitutes a good bacterial support and a good filter. It is thus used in on-site sanitation, treatment of drinking water, lagooning, aquariums.
[0036] Son extraction se fait dans les regions volcaniques. En France metropolitaine, c'est l'Auvergne qui est le principal fournisseur de pouzzolane. La pouzzolane est commercialisee selon une plage de granulometries importante permettant de couvrir l'ensemble des besoins. A titre d'exemple non limitatif, la societe POUZZOLANE DES DOMES qui est un des producteurs de pouzzolane installe dans le Puy de Dome propose de la pouzzolane dont la granulometrie va de 0 mm ä 100mm. Its extraction is done in volcanic regions. In mainland France, Auvergne is the main supplier of pozzolan. Pozzolan is marketed in a wide range of grain sizes to cover all needs. By way of non-limiting example, the company POUZZOLANE DES DOMES, which is one of the producers of pozzolana installed in the Puy de Dome, offers pozzolana whose particle size ranges from 0 mm to 100 mm.
[0037] La pouzzolane 4 est ici fournie en trois granulometries correspondant aux besoins principaux du marche. The pozzolan 4 is provided here in three particle sizes corresponding to the main needs of the market.
[0038] Une pouzzolane 4 de granulometrie la plus fine, comprise entre 0 et 0,3 mm. Cette pouzzolane sera referencee par la suite PoF. A pozzolan 4 of the finest particle size, between 0 and 0.3 mm. This pozzolan will be referred to below as PoF.
[0039] Une pouzzolane 4 de granulometrie moyenne, comprise entre 3 mm et 6 mm. Cette poudrette sera referencee par la suite PoM. A pozzolan 4 of average particle size, between 3 mm and 6 mm. This crumb will be referred to later as PoM.
[0040] Une poudrette 3 de granulometrie elevee, comprise entre 7 mm et 15 mm. Cette pouzzolane 4 grassiere sera referencee par la suite PoG. A crumb 3 of high particle size, between 7 mm and 15 mm. This grassy pozzolana 4 will be referred to as PoG in the following.
[0041] On conqoit que, dans le cadre de l'invention, il est possible d'utiliser d'autres granulometries que celles citees ou plus de trois granulometries, en fonction du revetement final desire et/ou du type de surface ä recouvrir. [0041] It is understood that, in the context of the invention, it is possible to use other particle sizes than those mentioned or more than three particle sizes, depending on the desired final coating and/or the type of surface to be covered.
[0042] Le liant utilise dans le mode prefere de l'invention est une resine polyurethane durcissant avec l'humidite de l'air. Elle possede un temps de prise de l'ordre de 30 minutes et, une fois durcie, reste relativement souple. Ces caracteristiques permettent une mise en oeuvre aisee, quelle que soit la surface ä recouvrir et autorise une mise en place directe du revetement sur la surface, y compris en exterieur, t Dans d'autres modes de realisation, d'autres types de liant sont employes. II s'agit par exemple de resines naturelles, ä base de polymeres ou bien d'un liant de composition complexe. The binder used in the preferred embodiment of the invention is a polyurethane resin hardening with air humidity. It has a setting time of about 30 minutes and, once hardened, remains relatively flexible. These characteristics allow an easy implementation, whatever the surface to be covered and authorizes a direct installation of the coating on the surface, including outside, t In other embodiments, other types of binder are employees. These are, for example, natural resins, based on polymers or else on a binder of complex composition.
[0043] La demanderesse a effectue plusieurs essais lors desquels le ratio entre la pouzzolane et la poudrette varie. Afin d'optimiser le materiau, c'est-ä-dire obtenir le meilleur compromis entre les diverses caracteristiques de chacun desconstituants tout en preservant un aspect esthetique du revetement et en limitant les eventuelles nuisances liees ä un pourcentage trop eleve de poudrette, notamment l'odeur, il a ete retenu de realiser un materiau comportant entre 40% et 80% de pouzzolane et entre 60% et 20% de poudrette. Avantageusement selon un premier mode de realisation, le pourcentage de pouzzolane est compris entre 65% et 75% et celui de poudrette entre 35% et 25%. De maniere preferee, un materiau de composition optimale selon ce premier mode de realisation a un pourcentage de pouzzolane voisin de 70% pour 30% de poudrette. [0043] The applicant has carried out several tests during which the ratio between the pozzolan and the crumb varies. In order to optimize the material, that is to say to obtain the best compromise between the various characteristics of each of the constituents while preserving an aesthetic appearance of the coating and limiting the possible nuisances linked to an excessively high percentage of crumb, in particular the smell, it was decided to produce a material containing between 40% and 80% pozzolan and between 60% and 20% crumb. Advantageously according to a first embodiment, the percentage of pozzolan is between 65% and 75% and that of crumb between 35% and 25%. Preferably, a material of optimal composition according to this first embodiment has a percentage of pozzolan close to 70% for 30% crumb.
[0044] Selon un deuxieme mode de realisation de l'invention, le pourcentage de pouzzolane est compris entre 40% et 60%, celui de poudrette entre 60% et 40%. Avantageusement, dans ce deuxieme mode de realisation, les pourcentages de pouzzolane et de poudrette sont chacun voisins de 50% According to a second embodiment of the invention, the percentage of pozzolan is between 40% and 60%, that of crumb between 60% and 40%. Advantageously, in this second embodiment, the percentages of pozzolan and crumb are each close to 50%
[0045] Les pourcentages des premier et deuxieme modes de realisation sont donnes en mässe sur le melange brüt de pouzzolane et de poudrette, avant ajout du liant et d'eventuels autres additifs. The percentages of the first and second embodiments are given in mass on the raw mixture of pozzolan and crumb, before adding the binder and any other additives.
[0046] Afin d'assurer la tenue du melange brüt, pouzzolane et poudrette, le liant est ajoute ä raison d'un pourcentage allant jusqu'ä environ 20% en mässe du materiau final. [0046] In order to ensure the behavior of the raw mixture, pozzolan and crumb, the binder is added at the rate of a percentage ranging up to about 20% by mass of the final material.
[0047] On congoit qu'ä ces composants de base, on ajoute des additifs si besoin. II s'agit, par exemple, de colorant, de retardateur de prise, d'accelerateur de prise, de parfums, de desodorisant, d'antigel, de fongicides, de biocides ou autres. II est egalement possible d'incorporer des elements au materiau, cela avant la prise du liant. A titre d'exemple non limitatifs, on peut eiter des capteurs de temperature, de pression, d'humidite, d'ensoleillement, des etiquettes RFID, des puces electroniques d'identification, des balises GPS, de l'eclairage, des transducteurs sonores, des enceintes acoustiques, des Organes de communication ou autres. [0047] It is understood that to these basic components, additives are added if necessary. These are, for example, colorants, setting retarders, setting accelerator, perfumes, deodorants, antifreeze, fungicides, biocides or others. It is also possible to incorporate elements into the material, before the binder has set. By way of non-limiting example, it is possible to include temperature, pressure, humidity, sunlight sensors, RFID tags, electronic identification chips, GPS beacons, lighting, sound transducers , loudspeakers, communication devices or others.
[0048] La demanderesse a constate, de maniere surprenante, que lorsque la Charge minerale est presente dans le materiau sous au moins deux granulometries differentes, la poudrette etant presente sous une granulometrie, on optimise les caracteristiques du materiau. En particulier, on obtient un materiau qui presente des proprietes drainantes superieures ä celles des enrobes drainants connus de l'etat de la technique, cela en ayant des caracteristiques d'isolant thermique comparables ä celles du bois et d'absorption acoustique du double de celles d'un enrobe drainant. [0048] The applicant has found, surprisingly, that when the mineral filler is present in the material in at least two different particle sizes, the crumb being present in one particle size, the characteristics of the material are optimized. In particular, a material is obtained which has draining properties superior to those of draining coatings known from the state of the art, this by having thermal insulation characteristics comparable to those of wood and sound absorption double those of wood. of a draining coating.
[0049] Les essais ont montre en particulier qu'un materiau comportant une Charge en pouzzolane avec deux granulometries differentes correspondant ä PoM et PoG, donc comprises entre 3 et 6 mm et entre 7 et 15mm permettent d'obtenir un materiau optimise lorsque le pourcentage de poudrette correspond ä PnM ou PnG, soit une granulometrie de 0,5 ä 2,5mm ou bien de 3 ä 6 mm. [0049] The tests have shown in particular that a material comprising a pozzolan filler with two different particle sizes corresponding to PoM and PoG, therefore between 3 and 6 mm and between 7 and 15 mm, makes it possible to obtain an optimized material when the percentage crumb corresponds to PnM or PnG, i.e. a particle size of 0.5 to 2.5 mm or else 3 to 6 mm.
[0050] Des essais ont egalement eu lieu avec de la pouzzolane presente sous les trois granulometries, donc avec PoF, PoM et PoG. Dans ce cas, la presence de PoF, donc de pouzzolane de granulometrie compris entre 0 et 0,3mm permet d'augmenter la resistance mecanique du materiau ainsi que ses proprietes d'isolant acoustique mais diminue ses capacites de drainage. La presence de trois granulometries de pouzzolane affecte egalement la couleur naturelle du materiau, celui-ci etant plus rouge. [0050] Tests have also taken place with pozzolan present in the three particle sizes, therefore with PoF, PoM and PoG. In this case, the presence of PoF, and therefore of pozzolan with a grain size between 0 and 0.3 mm, makes it possible to increase the mechanical resistance of the material as well as its acoustic insulation properties, but reduces its drainage capacities. The presence of three pozzolan grain sizes also affects the natural color of the material, which is redder.
[0051] Un materiau avec PoM, PoG et PnG sera sensiblement plus rouge qu'un materiau de composition PoM, PoG et PnM. [0051] A material with PoM, PoG and PnG will be significantly redder than a material with PoM, PoG and PnM composition.
[0052] Les essais effectues avec un materiau de composition PoM, PoG et PnG donnent une resistance ä la flexion maximale Rfmax de 141N pour un deplacement de 12 mm. Le materiau presente une deformation de 10% pour une contrainte exercee de 0,55 Mpa. En d'autres termes, un tel materiau a une deformabilite elastique importante, un caractere amortissant et une ductilite ä la rupture elevee. [0052] The tests carried out with a material of composition PoM, PoG and PnG give a resistance to maximum bending Rfmax of 141N for a displacement of 12 mm. The material presents a deformation of 10% for an exerted stress of 0.55 Mpa. In other words, such a material has high elastic deformability, cushioning character and high fracture ductility.
[0053] La conductivite thermique est de 0,1148 W/m.k, la diffusivite de 34,8 m2/s et l'effusivite de 445 W.s1/2/m2/K. Le materiau a donc des proprietes isolantes similaires ä celles du bois. Sa conductivite thermique est meilleure que celle des enrobes couramment utilises pour faire un revetement routier, ce qui reduit la capacite ä absorber et ä restituer la chaleur. Par ailleurs, on n'observe aucune perte de mässe apres les cycles de gel/degel, cela associe ä une excellente tenue au gel du materiau. The thermal conductivity is 0.1148 W/m.k, the diffusivity 34.8 m2/s and the effusivity 445 W.s1/2/m2/K. The material therefore has insulating properties similar to those of wood. Its thermal conductivity is better than that of the mixes commonly used to make road surfacing, which reduces the ability to absorb and release heat. Furthermore, no loss of mass is observed after the freeze/thaw cycles, which is associated with an excellent resistance to freezing of the material.
[0054] Les performances de drainage du materiau ont ete mesurees selon la norme en vigueur. Ainsi, avec un revetement d'une epaisseur de 3 cm, la vitesse de percolation Vperc est de 4,7 cm/s, sachant qu'un materiau est considere comme drainant ä partir de Vperc =1 cm/s. Le materiau est donc environ quatre fois plus drainant qu'un enrobe drainant classique, etant entendu que selon les formulations choisies, donc selon les granulometries retenues, le materiau est de deux ä cinq fois plus drainant qu'un enrobe classique. The drainage performance of the material was measured according to the standard in force. Thus, with a coating with a thickness of 3 cm, the percolation speed Vperc is 4.7 cm/s, knowing that a material is considered as draining from Vperc =1 cm/s. The material is therefore approximately four times more draining than a conventional draining coating, it being understood that depending on the formulations chosen, therefore according to the particle sizes selected, the material is two to five times more draining than a conventional coating.
[0055] Les capacites d'absorption acoustique, selon le coefficient d'absorption alpha Sabine sont de 0,6. En d'autres termes, le materiau est vingt fois plus absorbant, au niveau acoustique, qu'un asphalte et deux fois plus qu'un enrobe drainant. The sound absorption capacities, according to the alpha Sabine absorption coefficient, are 0.6. In other words, the material is twenty times more absorbent, at the acoustic level, than an asphalt and twice as much as a draining coating.
[0056] Un tel materiau peut etre mis en oeuvre selon un procede egalement objet de l'invention. Dans une premiere etape, selon le revetement ä effectuer, donc, par exemple, en fonction de la couleur voulue, si le revetement doit etre surtout drainant, isolant thermique, phonique, si la surface ä revetir est horizontale ou non, selon l'epaisseur souhaitee du revetement ou d'autres criteres, on choisira les granulometries de la poudrette 3 et de la pouzzolane 4. [0056] Such a material can be implemented according to a process which is also the subject of the invention. In a first step, depending on the coating to be made, therefore, for example, depending on the desired color, if the coating must be above all draining, thermally insulating, soundproofing, if the surface to be coated is horizontal or not, depending on the thickness of the coating or other criteria, the particle sizes of powder 3 and pozzolan 4 will be chosen.
[0057] Si besoin, d'autres elements seront choisis et formeront un complement de Charge au materiau. II s'agit, par exemple, de colorant, de retardant ou d'accelerateur de prise, d'antigel, de Charge metallique et/ou magnetique, de marqueurs electroniques tels que des puces RFID ou GPS, des capteurs. Dans tous les cas, ces elements additionnels restent minoritaires et ne modifient pas sensiblement les caracteristiques du materiau. [0057] If necessary, other elements will be chosen and will form an additional charge to the material. These are, for example, dye, retardant or setting accelerator, antifreeze, metallic and/or magnetic filler, electronic markers such as RFID or GPS chips, sensors. In all cases, these additional elements remain in the minority and do not significantly modify the characteristics of the material.
[0058] Une fois les granulometries de la pouzzolane 4 et de la poudrette 3 retenues, ces composants, avec eventuellement les elements additionnels, sont melanges jusqu'ä l'obtention d'un melange homogene. [0058] Once the particle sizes of the pozzolan 4 and of the crumb 3 have been selected, these components, possibly with the additional elements, are mixed until a homogeneous mixture is obtained.
[0059] L'etape suivante consiste ä incorporer au melange homogene obtenu precedemment un liant, ici une resine Polyurethane. L'incorporation du liant peut se faire soit immediatement ä la suite de l'etape de melange soit ulterieurement. Dans ce dernier cas, le melange homogene est fourni pret ä l'emploi ä l'utilisateur qui incorporera le liant juste avant la mise en place finale du materiau. De la Sorte, il est possible de fournir des melanges de poudrette 3 et de pouzzolane 4 de granulometries adaptees ä des besoins donnes et pretes ä l'emploi. The next step consists in incorporating into the homogeneous mixture obtained previously a binder, here a polyurethane resin. The incorporation of the binder can take place either immediately following the mixing step or subsequently. In the latter case, the homogeneous mixture is supplied ready for use to the user who will incorporate the binder just before the final placement of the material. In this way, it is possible to supply mixtures of crumb 3 and pozzolan 4 with particle sizes adapted to given needs and ready to use.
[0060] Une fois le liant incorpore au melange homogene, ce dernier est pret ä etre reparti sur au moins une partie d'une surface donnee. Gelte surface est, dans un mode de realisation, la surface finale destinee ä recevoir le materiau. Typiquement, ce mode de realisations se rencontre lorsque l'on reparti directement le melange pret ä l'emploi sur un sol en interieur ou en exterieur, une voie de circulation, une aire de jeu, un parking, un terrain de sport. [0060] Once the binder has been incorporated into the homogeneous mixture, the latter is ready to be distributed over at least part of a given surface. This surface is, in one embodiment, the final surface intended to receive the material. Typically, this embodiment is encountered when the ready-to-use mixture is distributed directly on an indoor or outdoor floor, a traffic lane, a playground, a parking lot, a sports field.
[0061] Selon un autre mode de realisation, la surface concernee est celle d'un moule. Dans ce cas, on produit des dalles, d'epaisseur et de dimensions preetablies, de materiau. Ces dalles seront ensuite utilisees pour revetir au moins une partie d'une surface, de fagon similaire ä une dalle en ceramique ou un pave. Dans un tel mode de realisation, il est ainsi possible de stocker, transporter et utiliser le materiau dans un lieu et/ou un moment eloigne de son lieu et/ou moment de production. According to another embodiment, the surface concerned is that of a mold. In this case, slabs are produced, of pre-established thickness and dimensions, of material. These slabs will then be used to cover at least part of a surface, similar to a ceramic slab or a paving stone. In such an embodiment, it is thus possible to store, transport and use the material in a place and/or a time remote from its place and/or time of production.
