Description
<Desc/Clms Page number 1>
La présente invention concerne une composition utile notamment pour la protection des sols et surfaces ainsi qu'un procédé de protection des sols et surfaces mettant en oeuvre ladite composition. <Desc / Clms Page number 1>
The present invention relates to a composition useful in particular for protecting floors and surfaces as well as a process for protecting floors and surfaces using said composition.
L'invention trouve application notamment dans le domaine de l'environnement, de l'industrie, de l'agriculture, du domestique. The invention finds application in particular in the field of environment, industry, agriculture, domestic.
Il existe actuellement des protections que l'on pose au pied des arbres pour limiter le développement des herbes adventices et maintenir l'humidité. Ces protections (film plastique, dalle de bois, mulch d'écorce, etc.) ont le principal inconvénient d'être lourdes à mettre en oeuvre (préparation du sol, pose soignée, coût élevé), inesthétiques et très difficilement biodégradables, notamment pour les plastiques (qui sont les plus largement utilisés). There are currently protections that are placed at the foot of trees to limit the development of weeds and maintain humidity. These protections (plastic film, wooden slab, bark mulch, etc.) have the main disadvantage of being heavy to implement (soil preparation, careful laying, high cost), unsightly and very difficult to biodegradable, especially for plastics (which are the most widely used).
Il est donc souhaitable de disposer d'un produit simple, écologique, facile à mettre en oeuvre et susceptible de durer au moins 1 an, afin d'assurer, notamment au pied des végétaux ligneux (arbres, arbustes, isolés ou en massif), une protection qui empêche la pousse des herbes adventices et qui limite l'évaporation. It is therefore desirable to have a simple, ecological product, easy to use and capable of lasting at least 1 year, in order to ensure, in particular at the foot of woody plants (trees, shrubs, isolated or in clumps), a protection which prevents the growth of weeds and which limits evaporation.
Il a maintenant été découvert, et c'est le fondement de l'invention, qu'il est possible d'utiliser un polymère filmogène naturel, tel que du latex naturel, éventuellement en combinaison avec une charge minérale et/ou un agent épaississant, pour protéger efficacement et durablement les sols et surfaces. It has now been discovered, and this is the basis of the invention, that it is possible to use a natural film-forming polymer, such as natural latex, optionally in combination with a mineral filler and / or a thickening agent, to effectively and durably protect floors and surfaces.
Ainsi, selon un premier aspect, l'invention concerne une composition aqueuse ou huileuse pour protéger les sols et surfaces, qui comprend a) du latex naturel ; b) au moins une charge minérale et/ou au moins un agent épaississant. Avantageusement, la composition conforme à l'invention comprend du latex naturel, au moins une charge minérale, et au moins un agent épaississant. Thus, according to a first aspect, the invention relates to an aqueous or oily composition for protecting floors and surfaces, which comprises a) natural latex; b) at least one mineral filler and / or at least one thickening agent. Advantageously, the composition according to the invention comprises natural latex, at least one mineral filler, and at least one thickening agent.
Par "latex naturel", on entend au sens de la présente invention le liquide sécrété par l'hévéa, notamment Hevea brasifensis, non-coagulé. Généralement, ce liquide a une teneur en caoutchouc de l'ordre de 60% au minimum, telle que mesurée selon la norme IS02004, et représente environ 10 à 90% en poids sec de la composition. Ce terme englobe également des formulations dans lesquelles le latex est chargé en soufre. By "natural latex" is meant in the sense of the present invention the liquid secreted by rubber, especially Hevea brasifensis, non-coagulated. Generally, this liquid has a rubber content of the order of at least 60%, as measured according to standard IS02004, and represents approximately 10 to 90% by dry weight of the composition. This term also includes formulations in which the latex is loaded with sulfur.

La charge minérale utilisable dans le cadre de la présente invention est d'origine naturelle. A titre d'exemple, on peut citer notamment la silice ; un carbonate tel que le carbonate de calcium ; une argile, en particulier la bentonite et/ou le kaolin ; ou un mélange quelconque de ces composés ; la silice étant particulièrement préférée. Ainsi, la charge minérale peut comprendre de la silice seule, une argile seule, un mélange d'argiles, un mélange de silice et d'argile(s) éventuellement additionné de carbonate. The mineral filler usable in the context of the present invention is of natural origin. By way of example, mention may in particular be made of silica; a carbonate such as calcium carbonate; a clay, in particular bentonite and / or kaolin; or any mixture of these compounds; silica being particularly preferred. Thus, the mineral filler can comprise silica alone, a clay alone, a mixture of clays, a mixture of silica and clay (s) optionally supplemented with carbonate.
La charge minérale représente de préférence environ 10 à 85% en poids sec de la composition. Lorsque la charge minérale est constituée par un mélange de composés, le rapport entre les différents composés peut varier indifféremment pour autant que la quantité totale de charge utilisée respecte la gamme indiquée ci-dessus. A titre indicatif, lorsque la charge minérale est constituée par un mélange de bentonite et de kaolin, ces deux constituants peuvent être utilisés dans un rapport pondéral compris entre environ 1:5 et 5:1. Lorsque la charge minérale est constituée par un mélange de silice et d'argile, ces deux constituants peuvent être utilisés dans un rapport pondéral compris entre environ 1:4 et 4:1. The mineral filler preferably represents approximately 10 to 85% by dry weight of the composition. When the mineral filler consists of a mixture of compounds, the ratio between the different compounds can vary indifferently provided that the total quantity of filler used respects the range indicated above. As an indication, when the mineral filler consists of a mixture of bentonite and kaolin, these two constituents can be used in a weight ratio of between approximately 1: 5 and 5: 1. When the mineral filler consists of a mixture of silica and clay, these two constituents can be used in a weight ratio of between approximately 1: 4 and 4: 1.
L'agent épaississant utilisable dans le cadre de la présente invention est biodégradable. A titre d'exemple, on peut citer notamment les alginates notamment les alginates riches en colloïdes glucuroniques et mannuroniques, les xanthanes, les carraghénanes, la gélatine, la gomme guar, une colle algale, de l'amidon, de la farine, ou un mélange quelconque de ces composés. The thickening agent which can be used in the context of the present invention is biodegradable. By way of example, there may be mentioned in particular alginates, in particular alginates rich in glucuronic and mannuronic colloids, xanthans, carrageenans, gelatin, guar gum, an algal glue, starch, flour, or a any mixture of these compounds.
Avantageusement, l'agent épaississant représente environ 0,5 à 5% en poids sec de la composition. Lorsque l'agent épaississant est constitué par un mélange de composés, le rapport entre les différents composés peut varier indifféremment pour autant que la quantité totale d'agent épaississant utilisé respecte la gamme indiquée ci- dessus. Advantageously, the thickening agent represents approximately 0.5 to 5% by dry weight of the composition. When the thickening agent consists of a mixture of compounds, the ratio between the different compounds can vary indifferently provided that the total amount of thickening agent used complies with the range indicated above.
Selon un mode de réalisation particulier, la composition conforme à l'invention peut également comprendre c) jusqu'à environ 1 % en poids sec de la composition d'un ou plusieurs additifs choisis en particulier parmi les colorants naturels (donc biodégradables), les parfums et autres substances aromatisées, les anti- oxydants, les oligo-éléments. According to a particular embodiment, the composition in accordance with the invention may also comprise c) up to approximately 1% by dry weight of the composition of one or more additives chosen in particular from natural dyes (therefore biodegradable), perfumes and other flavored substances, antioxidants, trace elements.
<Desc/Clms Page number 3><Desc / Clms Page number 3>
Bien évidemment, la somme des constituants a), b) et éventuellement c) est égale à 100%. Obviously, the sum of the constituents a), b) and possibly c) is equal to 100%.
Dans la composition conforme à l'invention, l'eau ou l'huile représente généralement environ 3 à 8 fois le poids sec des constituants a), b) et éventuellement c). Dans le cas d'une composition huileuse, l'huile est une huile naturelle comme l'huile de colza ou de tournesol. In the composition according to the invention, the water or the oil generally represents approximately 3 to 8 times the dry weight of the constituents a), b) and optionally c). In the case of an oily composition, the oil is a natural oil such as rapeseed or sunflower oil.
La composition conforme à l'invention peut être préparée de manière conventionnelle en mélangeant les différents ingrédients qui la composent. The composition in accordance with the invention can be prepared in a conventional manner by mixing the various ingredients which compose it.
Elle permet non seulement une protection, mais également une fixation et un étanchement des sols et surfaces. Elle assure ainsi notamment une lutte contre l'érosion en agissant sur - la fixation des éléments constitutifs des sols, - la création d'un film protecteur contre les intempéries : gel, température, pluie, écoulement, vent, - la limitation de l'évaporation des sols. It allows not only protection, but also fixing and sealing of floors and surfaces. It thus ensures in particular a fight against erosion by acting on - the fixing of the constituent elements of the soil, - the creation of a protective film against the bad weather: frost, temperature, rain, flow, wind, - the limitation of soil evaporation.
La composition conforme à l'invention peut être appliquée en utilisant une technique de projection pour constituer un film sur la surface destinée à être protégée. Ainsi, selon un autre aspect, l'invention concerne un procédé pour protéger, fixer ou étancher les sols et surfaces, qui consiste à appliquer directement (c'est-à-dire sans traitement préalable) sur lesdits sols ou sur lesdites surfaces, de préférence par pulvérisation, du latex naturel ou une composition aqueuse à base de latex naturel, telle que définie ci-dessus. The composition according to the invention can be applied using a spraying technique to form a film on the surface intended to be protected. Thus, according to another aspect, the invention relates to a method for protecting, fixing or waterproofing floors and surfaces, which consists in applying directly (that is to say without prior treatment) to said floors or to said surfaces, preferably by spraying, natural latex or an aqueous composition based on natural latex, as defined above.
Généralement, on utilisera le latex naturel ou la composition conforme à l'invention en une quantité comprise entre environ 0,5 et 3 I/m2 de surface à traiter, ce qui correspond à une quantité de produit sec de l'ordre de 0,3 à 1 kg/m2. Generally, natural latex or the composition in accordance with the invention will be used in an amount of between approximately 0.5 and 3 I / m2 of surface to be treated, which corresponds to an amount of dry product of the order of 0, 3 to 1 kg / m2.
Selon le type de sol et la protection désirés, il pourra être avantageux d'appliquer la composition en plusieurs couches, en variant si nécessaire la concentration de chaque couche. La première couche peut être avantageusement diluée à 20 ou 30 % afin d'obtenir une bonne adhérence sur les surfaces traitées. Depending on the type of soil and the protection desired, it may be advantageous to apply the composition in several layers, varying if necessary the concentration of each layer. The first layer can advantageously be diluted to 20 or 30% in order to obtain good adhesion to the treated surfaces.
La composition conforme à l'invention est biodégradable et résistante dans le temps, avec une "durée de vie" pouvant être supérieure à un an, ce qui est avantageux The composition according to the invention is biodegradable and resistant over time, with a "lifespan" which can be greater than one year, which is advantageous.

du point de vue économique. Elle pourra donc trouver application, notamment dans les domaines suivants - la lutte contre l'érosion des sols : fixation des talus, des sables, dunes, des zones érodées, etc., - les espaces verts, les plantations : protection au pied des végétaux ou des massifs pour faciliter la reprise et réduire l'entretien (arrosage et binage), - la protection des végétaux contre les animaux : création d'un film protecteur sur les arbres (contre les lapins, etc.), - l'amélioration de l'étanchéité des sols : fossé, bassin, etc., - la fixation de substrats sur les parois, rochers, talus, etc., - la fixation des colorants pour l'intégration des parois rocheuses, - la protection des bois extérieurs contre le pourrissement : poteau, clôture, etc., - la fixation des poussières : sur les pistes, carrières, chantiers, etc., - l'étanchement des surfaces, des toitures, etc., - la consolidation des matériaux poreux ou friables, etc. from an economic point of view. It may therefore find application, particularly in the following areas - the fight against soil erosion: fixing of slopes, sands, dunes, eroded areas, etc., - green spaces, plantations: protection at the foot of plants or beds to facilitate recovery and reduce maintenance (watering and hoeing), - protection of plants against animals: creation of a protective film on trees (against rabbits, etc.), - improvement of waterproofing of soils: ditch, basin, etc., - fixing of substrates on walls, rocks, embankments, etc., - fixing of dyes for the integration of rock walls, - protection of exterior wood against rotting: post, fence, etc., - fixing of dust: on tracks, quarries, construction sites, etc., - sealing of surfaces, roofs, etc., - consolidation of porous or brittle materials, etc.
