Abstract

Outer-insulation panel of a building, comprising a cellular insulating material, a hydraulic coating and a reinforcement structure embedded in the coating. The reinforcement structure is made of a polymer of low modulus of elasticity, preferably of polypropylene. Application to the insulation of dwellings.

Description

Perfectionnement aux enduits pour panneau d'isolation extérieure de batiments
La présente invention concerne un panneau d'isolation extérieure d'un bâtiment, comprenant un isolant alvéolaire, un enduit hydraulique et une armature de renforcement noyée dans l'enduit, dont le rôle est de répartir également les contraintes sur la surface de l'enduit.Improvement of coatings for exterior building insulation panels
The present invention relates to an exterior insulation panel of a building, comprising a cellular insulator, a hydraulic coating and a reinforcement reinforcement embedded in the coating, the role of which is to evenly distribute the stresses on the surface of the coating. .

La Demanderesse a déjà proposé dans sa demande de brevet français nO 82 18 004 du 27 octobre 1982, un panneau de ce genre, dans lequel l'enduit hydraulique est formé d'un ciment imprégné de polymétacrylate de méthyle, ou d'une résine époxyde de faible viscosité, et l'armature de renforcement d'un tissu métallique, de fibres de verre ou de matière plastique. L'adhérence de l'enduit hydraulique sur l'isolant alvéolaire, d'une part, et sur un enduit extérieur de finition, d'autre part, doit être assurée par des couches d'adhésif. The Applicant has already proposed in its French patent application No. 82 18 004 of October 27, 1982, a panel of this kind, in which the hydraulic coating is formed from a cement impregnated with polymethyl methacrylate, or from an epoxy resin. of low viscosity, and the reinforcing reinforcement of a metallic fabric, glass fibers or plastic. The adhesion of the hydraulic coating on the cellular insulation, on the one hand, and on an external finishing coating, on the other hand, must be ensured by layers of adhesive.

Celles-ci n'évitent cependant pas des fissurations de l'enduit hydraulique, et par suite de l'enduit extérieur de finition, sous l'effet des dilatations thermiques différentielles de l'enduit et de l'armature.These do not, however, prevent cracking of the hydraulic coating, and consequently of the exterior finishing coating, under the effect of differential thermal expansion of the coating and the reinforcement.

Ces fissurations sont nuisibles à l'aspect extérieur du batiment.These cracks are detrimental to the exterior appearance of the building.

La présente invention a pour but de procurer un panneau d'isolation extérieure de bâtiment qui ne présente pas le phénomène-de fissuration, et qui soit d'une structure plus simple que le panneau mentionne ci-dessus, et de fabrication plus rapide. The object of the present invention is to provide an exterior building insulation panel which does not exhibit the phenomenon of cracking, and which is of a simpler structure than the panel mentioned above, and which is more rapid in manufacture.

Le panneau selon l'invention est caractérisé en ce que son armature de renforcement est en un polymère de module d'élasticité faible. The panel according to the invention is characterized in that its reinforcing reinforcement is made of a polymer with a low modulus of elasticity.

Ce polymère est de préférence le polypropylène, qui joint à un module d'élasticité faible, lui permettant de suivre les dilatations et contractions thermiques de l'enduit, une grande légèreté et une grande inertie chimique. This polymer is preferably polypropylene, which joins to a low modulus of elasticity, allowing it to follow the thermal expansions and contractions of the coating, a great lightness and a great chemical inertia.

De préférence également, afin d'assurer un meilleur accrochage du polymère sur l'enduit, on munit les brins de l'armature, avant leur tissage pour former celle-ci, de fibrilles d'un matériau à radicaux organiques du type silane. Ce matériau peut être notamment le gammamétacryloxy-triméthoxysilane, tel que celui commercialisé sous la désignation "Memo!' par la Société Dynamit Nobel. On peut utiliser aussi avantageusement un dérivé silanique à longue chaîne, qui assure un meilleur enchevêtrement des chaînes à groupes silanes avec les channes carbonées du polymère, et par suite un meilleur accrochage physique des fibrilles sur le polymère. Preferably also, in order to ensure better adhesion of the polymer to the coating, the strands of the reinforcement are provided, before their weaving to form the latter, with fibrils of a material with organic radicals of the silane type. This material may in particular be gammametacryloxy-trimethoxysilane, such as that sold under the designation "Memo! ' by the company Dynamit Nobel, a long chain silane derivative can also be advantageously used, which ensures better entanglement of chains with silane groups with the carbonaceous chains of the polymer, and consequently better physical attachment of the fibrils to the polymer.

On peut bien entendu utiliser comme enduit un ciment hydraulique classique, ou un ciment poreux à pores remplis d'un polymère organique, tel que celui décrit dans la demande de brevet mentionnée cidessus. On peut également munir le ciment d'additifs limitant son retrait. It is of course possible to use as a coating a conventional hydraulic cement, or a porous pore cement filled with an organic polymer, such as that described in the patent application mentioned above. The cement can also be provided with additives limiting its shrinkage.

Pour préparer le panneau selon 11 invention, on applique sur une couche thermiquement isolante, par exemple en polystyrène alvéolaire, une couche d'enduit hydraulique, on noie dans la couche d'enduit l'armature en polymère à faible module d'élasticité, puis l'on recouvre éventuellement 11 enduit d'un enduit de finition assurant un bon aspect extérieur.  To prepare the panel according to the invention, a layer of hydraulic plaster is applied to a thermally insulating layer, for example of alveolar polystyrene, the polymer reinforcement with low elasticity is embedded in the plaster layer, then possibly covered 11 coated with a finishing coating ensuring a good external appearance.
