Abstract
Description
La présente demande a pour objet des éléments habillés préfabriqués de construction et leurs procédés de fabrication. The present application relates to prefabricated dressed construction elements and their manufacturing processes.
Les éléments préfabriqués de construction tels que ceux utilisés par exemple dans la construction de moyen de transport, dans le bâtiment, l'électro-ménager, l'ameublement, nécessitent parfois un habillage d'un revêtaient textile sur au moins une de leurs faces pour des raisons de confort, d'esthétique et d'intégration de processus de réalisation pour simplifier celui- ci. Prefabricated construction elements such as those used for example in the construction of means of transport, in building, household appliances, furniture, sometimes require a covering of a textile coating on at least one of their faces to reasons of comfort, aesthetics and integration of the production process to simplify it.
Ainsi, pour le garnissage intérieur de moyens de transport par eau, air, terre, tels qu'automobiles, wagons de chemins de fer, bateaux, cars, canyons, avions, que ces moyens de tranport servent pour du personnel ou des marchandiscs, il est connu de faire appel à un habillage intérieur en textile, cuir ou imitation posés selon des méthodes de sellerie longues et onéreuses. Récemment, il a été proposé d'associer du tricot k des pièces moulées lors du moulage de ces dernières.Toutefois, le tricot n'est généralesent extensible que dans un sens et les déforiations dues au moulage en particulier dans les zones très sollicitées telles que coins, Creux, etc , provoquent des points faibles, fragiles à l'éclatement, et des plis préjudiciables à l'aspect du produit fini. On a aussi songé à utiliser des textiles non-tissés réalisés à partir de fibres par voie sèche ou humide Toutefois, ces non-tissés ont une déforiabilité faible et une résistance à la rupture relative qui ne tonnent pas de bons résultats.Dans le bâtiment, la réalisation de cloisons préfabriquées facilite la construction ais il faut y ajouter ensuite une revêteioent, ce qui nécessite d'autres opérations. Thus, for the interior lining of means of transport by water, air, land, such as cars, railroad cars, boats, coaches, canyons, planes, whether these means of transport are used for personnel or merchants. is known to use an interior covering in textile, leather or imitation posed according to long and expensive upholstery methods. Recently, it has been proposed to combine knitting with molded parts during the molding of the latter. However, knitting is generally only stretchable in one direction and the deformations due to molding in particular in highly stressed areas such as corners, Hollow, etc., cause weak points, fragile at bursting, and folds detrimental to the appearance of the finished product. Consideration has also been given to using non-woven textiles produced from fibers by the dry or wet method. However, these non-wovens have a low deforability and a relative breaking strength which do not give good results. the production of prefabricated partitions facilitates construction, but a coating must then be added thereto, which requires other operations.
La présente demande se propose d'éviter les inconvénients des habillages textiles antérieurement proposés. The present application proposes to avoid the drawbacks of the textile covers previously proposed.
La présente invention a pour objet des éléments habillés préfabriqués de construction, caractérisés en ce qu'ils comportent en surface, au moins sur le coté visible, au moins un textile non-tissé de filaments continus synthétiques solidaire du support desdits éléments. The subject of the present invention is dressed prefabricated construction elements, characterized in that they comprise on the surface, at least on the visible side, at least one nonwoven fabric of synthetic continuous filaments secured to the support of said elements.
La présente demande a aussi pour objet un procédé pour la réalisation par moulage des éléments ci-dessus, caractérisé en ce que l'on associe avec le support et sur au moins une face de ce dernier au moins un non-tissé de filaments continus synthétiques puis que l'on soumet l'ensemble à une opération de formage dans une presse. The present application also relates to a process for the production by molding of the above elements, characterized in that one associates with the support and on at least one face of the latter at least one nonwoven of synthetic continuous filaments then that the assembly is subjected to a forming operation in a press.
La présente demande concerne un procédé pour la réalisation par injection des éléments ci-dessus décrits, caractérisé en ce que l'on injecte dans un moule froid une matière plastique, éventuellement chargée, ledit moule étant recouvert sur au moins une de ses faces internes d'au moins un textile non-tissé de filatents continus synthétiques. The present application relates to a method for producing by injection of the elements described above, characterized in that a plastic material, possibly loaded, is injected into a cold mold, said mold being covered on at least one of its internal faces. '' at least one nonwoven textile of synthetic continuous filatents.
Pour le moulage, les matières premières des supports sont de type connu, telles que carton ondulé, déchets de fibres textiles ou de fibre de verre, de fibres cellulosiques, enrobées de résines thermoformables, mousse rigide, pitre, ciment, matières plastiques chargées éventuellement de produits tels que talc, etc
Le non-tissé de filaments continus synthétiques utilisé est de préférence aiguilleté sur au moins une face d'un nombre de perforations supérieur à 50 perforations au centimètre carré.For molding, the raw materials of the supports are of known type, such as corrugated cardboard, waste of textile fibers or glass fiber, of cellulose fibers, coated with thermoformable resins, rigid foam, pitre, cement, plastics possibly loaded with products such as talc, etc.
The synthetic continuous filament nonwoven used is preferably needled on at least one face with a number of perforations greater than 50 perforations per square centimeter.
Ce non-tissé peut etre de couleur écrue, teint, coloré dans la masse, il peut etre imprimé au cadre, aux rouleaux, ou par transfert thermique. Le non-tissé est de préférence flambé sur au moins une face pour améliorer sa résistance au frottement. On utilise un non-tissé de poids compris entre 50 et 300 g/m2 de préférence entre 90 et 200 g/m2. Ces non-tissés sont obtenus par extrusion selon les procédés connus, de masses fondues de polymères synthétiques tels que ceux à base de polyamide1 polyester, polyoléfine, utilisés seuls, en mélange ou donnant lieu, lors de leur extrusion, à des produits bicomposites ou mixtes, on utilise de préférence un non-tissé à base de polyester tel que le polytéréphta late d'éthylène glycol extrudé seul ou en ne.. temps que du poly téréphtalate de butylène glycol pour donner des fils continus sixtes
Lc moulage peut être effectué à chaud à une t c a p é r a t u r e comprise e n t r e 100 et 2200C et à une p r c s s i o n comprise entre 0,5 et 100 bars/cm2 ou à froid avec une colle appropriée sur le support déjà formé par assemblage à l'aide d'un moule en deux parties en utilisant une pression comprise entre 0,5 et 100 bars.Lors du moulage, le non-tissé peut être utilisé seul ou avec un intercallaire qui peut être par exemple un fila plastique thermocollant par exemple en polyoléfinc, il est aussi possible d'associer le non-tissé et une matière plastique k structure alvéolaire puis d'utiliser l'intercallaire. L'intercallaire peut aussi être une poutre thermocollante. Lors de l'injection, le support injecté est en général k base de résine
ABS ou de polyoléfines chargées. L'injection et le soulage sont effectués selon les procédés connus et sur du matériel connu.This nonwoven can be of ecru color, dyed, colored in the mass, it can be printed with the frame, with the rollers, or by thermal transfer. The nonwoven is preferably flamed on at least one side to improve its resistance to friction. A nonwoven of weight between 50 and 300 g / m2 is used, preferably between 90 and 200 g / m2. These nonwovens are obtained by extrusion according to known methods, from melts of synthetic polymers such as those based on polyamide1 polyester, polyolefin, used alone, as a mixture or giving rise, during their extrusion, to bicomposite or mixed products , preferably a polyester-based nonwoven such as polyethylene terephta late extruded alone or in combination with poly butylene terephthalate glycol is used to give continuous six-ply yarns.
The molding can be carried out hot at a temperature between 100 and 2200C and at a pressure between 0.5 and 100 bars / cm2 or cold with an appropriate glue on the support already formed by assembly using '' a two-part mold using a pressure of between 0.5 and 100 bars. it is also possible to combine the nonwoven and a plastic material with a cellular structure and then use the interlayer. The interlayer can also be a fusible beam. During the injection, the injected support is generally k resin base
ABS or loaded polyolefins. The injection and the relief are carried out according to known methods and on known equipment.
Pour le forcage-moulage, on utilise des températures et pressions compatibles avec la matière première du textile non-tissé et les supports utilisés, par exemple lorsqu'on utilise un non-tissé teint ou imprimé, la température ne doit pas provoquer de dégra- dation du colon recherché.For forcing-molding, temperatures and pressures compatible with the raw material of the nonwoven fabric and the supports used are used, for example when a dyed or printed nonwoven is used, the temperature must not cause degradation. donation of the colonist sought.
Les non-tissés de filaments continus obtenus par voie fondue, contrairement aux non-tissés obtenus par voie sèche ou humide présentent une isotropie, une bonne déformabilité dans les zones très sollicitées, il n'y a pas d'amincissement dans les zones de forte déformation car la cohésion de ces nontissés de filaments continus permet une sollicitation de la matière sur une plus grande suface, il ne se produit pas de plis au moulage, pas d'éclatement sur les parties en relief le non-tissé est opaque, il présente une bonne résistance à l'abrasion, à la lumière, au vieillissement, une bonne tenue thermique, une solidité au nettoyage ; on obtient ainsi en une seule opération un complexe support/textile en une seule pièce ce qui est important du point de vue économique. Indépendemment de l'utilisation de non-tissés à surface plane, il est possible d'utiliser des non-tissés gaufrés entre cylindres métalliques gravés et chauffés par exemple pour le polytéréphtalate d'éthylène glycol à une température de 220/2300C. Avec ces éléments, on peut ainsi réaliser par exemple tout habillage intérieur de tout moyen de transport tel que pavillons, panneaux de portières, arrières de sièges, tableaux de bord, il est aussi possible d'obtenir en ameublement un mobilier plastique à surface textile en une seule opération, dans le batiment des cloisons d1apparte- ments avec revêtement textile incorporé lors de la réalisation des cloisons préfabriquées, l'habillage intérieur et en extérieur d'électroménager tel que machine à laver, réfrigérateur. The nonwovens of continuous filaments obtained by the melt process, unlike the nonwovens obtained by the dry or wet route exhibit isotropy, good deformability in the highly stressed areas, there is no thinning in the areas of strong deformation because the cohesion of these nonwovens of continuous filaments allows a solicitation of the material on a larger surface, there are no folds in the molding, no bursting on the raised parts the nonwoven is opaque, it has good resistance to abrasion, to light, to aging, good thermal resistance, fastness to cleaning; in this way a support / textile complex is obtained in a single piece, which is important from an economic point of view. Regardless of the use of nonwovens with a flat surface, it is possible to use embossed nonwovens between etched and heated metal cylinders for example for polyethylene terephthalate glycol at a temperature of 220 / 2300C. With these elements, it is thus possible, for example, to produce any interior covering for any means of transport such as pavilions, door panels, rear seats, dashboards, it is also possible to obtain plastic furniture with textile surface in furniture. a single operation, in the building of apartment partitions with textile covering incorporated during the production of the prefabricated partitions, the interior and exterior cladding of household appliances such as washing machine, refrigerator.

We heat the mold to 190OC for the realization of a pavilion of automobiles, we preheat the support for two minutes then we cover the file and the nonwoven and we practice a direct pressing in a single operation and not in steps using a pressure of 4 bars / cm2.
Exemnle 3
Pour la réalisation d'éléments tels que traverses, brancards avant et arrière, pieds avant et milieu de véhicules automobiles, on utilise d'une part, le non-tissé de l'exemple 2 teint dans la masse en colon bleu et d'autre part, une résine polypropylène chargée de talc.Claim 3
For the production of elements such as crosspieces, front and rear stretchers, front legs and middle of motor vehicles, the nonwoven of Example 2 dyed in the mass with blue colon is used on the one hand and on the other hand hand, a polypropylene resin loaded with talc.
La réalisation des pièces se fait par injection en maintenant le moule vertical froid recouvert du non-tissé sur la face du moule opposée à celle de l'injection ; l'injection du polypropylène chargé est effectuée à 18O/1900C sous une pression de 500 bars au centimètre carré. On procède au démoulage après un temps de 2,5 minutes. L'utilisation du textile au moment de la réalisation de la pièce est pratique ec économique. The parts are produced by injection while keeping the cold vertical mold covered with the nonwoven on the face of the mold opposite to that of the injection; the injection of the loaded polypropylene is carried out at 18O / 1900C under a pressure of 500 bars per square centimeter. Unmolding is carried out after 2.5 minutes. The use of textiles when making the piece is practical and economical.
Exemple 4
Pour la réalisation d'un pavillon d'automobiles, on utilise un non-tissé de filaments continus polypropylène de poids 120 g/m2, titre au brin 3 dtex, aiguilleté recto/verso avec 10 perforations au centimère carré. Ce non-tissé est imprimé au cadre rotatif avec un motif pieds de poule sur la face sortie aiguilles du deuxième aiguilletage. On procède ensuite à l'assemblage sur l'envers d'une mousse polyuréthane souple de 1,5 mm d'épaisseur par le procédé de flammage de la mousse.Example 4
For the production of an automobile pavilion, a nonwoven of continuous polypropylene filaments weighing 120 g / m2, strand count 3 dtex, needled recto / verso with 10 perforations per square centimeter is used. This nonwoven is printed on the rotary frame with a houndstooth pattern on the needle exit face of the second needling. Then proceed to the assembly on the back of a flexible polyurethane foam 1.5 mm thick by the flame process of the foam.
Le complexe non-tissé-mousse est appliqué sur un carton cellulosique triple épaisseur avec intercallaire ondulé de 2 mm d'épaisseur revêtu de colle de type EVA (Ethylène Vinyle Acétate) à raison de 50 g/m2 de produit sec par dépôt d'une pulvérisation d'une dispersion aqueuse à 30 il d'extrait sec. The non-woven-foam complex is applied to a triple-thickness cellulosic cardboard with a 2 mm thick corrugated interlayer coated with EVA (Ethylene Vinyl Acetate) glue at a rate of 50 g / m2 of dry product by depositing a spraying of an aqueous dispersion with 30 μl of dry extract.
L'ensemble est placé sur la partie le d'un ioule métallique chauffé à 1200C. La partie femelle du moule est immédiatement abaissée sous une pression de 3 barsjcm2, on démoule ensuite après 1 minute 30. The assembly is placed on the part of a metal ioule heated to 1200C. The female part of the mold is immediately lowered under a pressure of 3 barsjcm2, it is then removed from the mold after 1 minute 30.
