Description

La présente invention concerne un dispositif composite textile siliconeThe present invention relates to a silicone textile composite device

permettant une protection efficace par recouvrement total ou partiel d'objets ou d'êtres vivants. L'utilisation des composites textile-silicone est traditionnellement effectuée sous la forme d'enduction en faible épaisseur (de l'ordre du micron pouvant aller jusqu'a 1, voire 2 mm d'épaisseur), cette enduction de silicone qui protège bien le textile et les éléments sous jacents des rayonnements ultra violet, des salissures, et de la pluie (ou des projections d'eau), ne possède pas une épaisseur suffisante pour permettre une bonne résilience, ni une isolation thermique satisfaisante. Il existe, d'autre part des mousses de silicones, d'épaisseur suffisante, qui effectuent efficacement ce rôle d'amortisseur des chocs et des différences de température, mais elles ne possèdent pas de trame textile noyée en leur sein ou en périphérie qui soit, d'une part, protégée des rayonnements ultra violet, des salissures des projections d'eau, et permette, d'autre part, l'assemblage par couture. Le dispositif selon l'invention permet de remédier à ces inconvénients. Il comporte en effet selon une première caractéristique, une couche de surface, appelée couche extérieure (la plus éloignée de l'objet ou de l'être vivant à protéger) mesurant entre 1 et 3 mm d'épaisseur en silicone muni d'une trame textile noyée qui permet d'une part l'assemblage par couture et d'autre part, réalise une interface capable de résister aux sollicitations mécaniques variées de l'environnement, et en particulier à l'abrasion. Puis une couche de silicone intérieure (plus proche que la précédente de l'objet ou de l'être vivant) possédant des lacunes gazeuses noyées dans le silicone. Ces éléments lacunaires peuvent être des bulles de gaz, obtenues par barbotage, ou agitation, avant la réticulation, vulcanisation ou polymérisation du silicone ou encore une mousse de silicone ou un textile épais et suffisamment ajouré pour emprisonner au sein de l'espace créé par ses fibres, un gaz qui remplie le rôle d'isolant, thermique, phonique et procure un bon amorti aux chocs. L'espace amortissant ainsi ménagé lors de la réalisation du dispositif est pérennisé, grâce aux propriétés de vulcanisation, polymérisation ou de réticulation des silicones. Une continuité intermittente mais suffisante est assurée par le silicone entre cette partie isolante intérieure (lacunaire) et celle de surface, extérieure (munie du textile de protection) afin de maintenir la cohésion du dispositif et éviter le phénomène de délaminage. Cette couche, isolante sur le plan thermique, phonique, et des chocs, peut mesurer entre 3 mm et 3cm d'épaisseur selon les utilisations envisagées. Elle est destinée au contact ou à la proximité immédiate des objets ou des êtres vivants que l'on souhaite protéger des agressions extérieures, c'est à dire du milieu en deçà de la couche extérieure du dispositif décrite précédemment. Une dernière couche textile peut être ajoutée entre l'objet ou l'être vivant et la couche intérieure du dispositif de façon à réaliser une interface qui glisse plus facilement 5 sur les supports à protéger, par exemple, la peau. Selon des modes particuliers de réalisation : Le dispositif est réalisé sous formes de plaques, en coulée simple avec interposition textile. - Le dispositif est réalisé sous formes de rouleaux par enduction unique ou 10 successives. - Le dispositif mesure au minimum 4 mm d'épaisseur. - Le dispositif mesure au maximum 40mm d'épaisseur. le textile participant à la couche de surface (extérieure) peut présenter des élasticités variables selon les lignes de chaînes et trames. 15 - le textile participant à la couche de surface (extérieure), peut présenter des caractéristiques lui permettant de résister au poinçonnement, voire aux impacts de projectiles. Kevlar ou matériau équivalent. - La couche de silicone intérieure effectuant le rôle d'isolant thermique phonique et aux chocs peut être une mousse de silicone. 20 - La dureté Shore A du silicone utilisé varie typiquement entre 20 et 80. - La dureté Shore A du silicone utilisé pour la couche de surface ou la couche isolante est variable. Un silicone unique est employé pour la réalisation du dispositif. - Le silicone utilisé est un RTV (Room Température Vulcanization) 25 Les silicones utilisés peuvent être transparents. Les dessins annexés illustrent l'invention : La figure 1 représente en coupe, le dispositif de l'invention. Les figures 2 et 3 représentent en coupe, une variante de ce dispositif. En référence à ces dessins le dispositif comporte une couche extérieure (2) 30 mesurant en tout entre lmm et 3 mm d'épaisseur réalisée en silicone recouvrant un textile (1) qui lui sert d'armature pour pouvoir assembler le dispositif à des éléments textiles ou à lui même par couture. Une couche intérieure isolante (3) mesurant entre 3mm et 3 cm d'épaisseur réalisée en polymère de silicone possédant des bulles de gaz.  allowing effective protection by total or partial recovery of objects or living beings. The use of textile-silicone composites is traditionally carried out in the form of thin coating (of the order of one micron up to 1 or even 2 mm thick), this silicone coating which protects the textile and the underlying elements of ultraviolet radiation, dirt, and rain (or splashing water), does not have a sufficient thickness to allow good resilience or satisfactory thermal insulation. There are, on the other hand, silicone foams, of sufficient thickness, which effectively perform this role of shock absorber and temperature differences, but they do not have a textile frame embedded in them or on the periphery which is on the one hand, protected from ultraviolet rays, dirt from splashing water, and, on the other hand, allows assembly by sewing. The device according to the invention overcomes these disadvantages. It comprises in fact according to a first characteristic, a surface layer, called outer layer (furthest from the object or the living being to be protected) measuring between 1 and 3 mm thick silicone provided with a frame embedded textile that allows on the one hand the assembly by stitching and on the other hand, provides an interface capable of withstanding the various mechanical stresses of the environment, and in particular to abrasion. Then an inner silicone layer (closer than the previous object or living being) with gas gaps embedded in the silicone. These lacunary elements may be gas bubbles, obtained by bubbling, or stirring, before crosslinking, vulcanization or polymerization of silicone or a silicone foam or a thick textile and sufficiently openwork to trap within the space created by its fibers, a gas that fulfills the role of insulation, thermal, sound and provides good shock absorption. The damping space thus formed during the production of the device is maintained, thanks to the properties of vulcanization, polymerization or crosslinking of silicones. An intermittent but sufficient continuity is ensured by the silicone between this insulating part inside (lacunary) and that of outer surface (provided with the protective textile) in order to maintain the cohesion of the device and avoid the phenomenon of delamination. This layer, thermally insulating, soundproof, and shocks, can measure between 3 mm and 3 cm thick depending on the intended uses. It is intended for the contact or immediate proximity of objects or living beings that one wishes to protect from external aggressions, that is to say the medium below the outer layer of the device described above. A last textile layer may be added between the object or the living being and the inner layer of the device so as to provide an interface that slides more easily on the supports to be protected, for example, the skin. According to particular embodiments: The device is made in the form of plates, in simple casting with textile interposition. The device is produced in the form of rolls by single or successive coating. - The device measures at least 4 mm thick. - The device measures at most 40mm thick. the textile participating in the (outer) surface layer may have variable elasticities along the lines of chains and wefts. The textile participating in the (outer) surface layer may have characteristics enabling it to withstand punching or even projectile impacts. Kevlar or equivalent material. - The inner silicone layer performing the role of sound and shock thermal insulation may be a silicone foam. The Shore A hardness of the silicone used typically varies between 20 and 80. The Shore A hardness of the silicone used for the surface layer or the insulating layer is variable. A single silicone is used for the realization of the device. The silicone used is RTV (Room Temperature Vulcanization) The silicones used can be transparent. The accompanying drawings illustrate the invention: FIG. 1 represents in section, the device of the invention. Figures 2 and 3 show in section, a variant of this device. With reference to these drawings the device comprises an outer layer (2) measuring in all between 1 mm and 3 mm thick made of silicone covering a textile (1) which serves as a reinforcement for assembling the device to textile elements or by itself by sewing. An insulating inner layer (3) measuring between 3 mm and 3 cm thick made of silicone polymer having gas bubbles.

Dans la forme de réalisation selon la figure .2, le dispositif présente une dernière couche textile (4) qui possède une face intérieure qui n'est pas noyée dans le silicone et peut faciliter le glissement du dispositif sur les supports envisagés. Dans la forme de réalisation selon la figure 3, la couche isolante (3) est réalisée 5 grâce à une mousse de silicone noyée au sein du dispositif La couche textile (4) n'existe plus.  In the embodiment according to Figure .2, the device has a last textile layer (4) which has an inner face which is not embedded in the silicone and can facilitate the sliding of the device on the envisaged supports. In the embodiment according to FIG. 3, the insulating layer (3) is produced by means of a silicone foam embedded in the device. The textile layer (4) no longer exists.
