Abstract

Process for manufacturing resin and, in particular, reinforced polyurethane articles, characterized by the following sequence of operations: a) an initial layer of said resin is applied to a shaped support, such as a mould base; b) a mesh reinforcement is then immediately placed on said layer; c) before the initial layer has undergone polymerization, a second resin layer is applied to the mesh, whereby said second resin layer is identical or capable of being polymerised together with the initial layer and is integrated with the latter through the mesh embedded in the uniform mass formed when the two layers set together.

Description

Le présent procédé permet de réaliser un matériau composite possédant en surface une couche permettant d'obtenir, aspect-teinte-étanchéité-protection aux rayonnements agressifs ou toute autre caractéristique requise. The present method makes it possible to produce a composite material having on the surface a layer making it possible to obtain, appearance-color-tightness-protection against aggressive radiation or any other required characteristic.

Ce procédé a été mis au point pour permettre, d'une part, l'accrochage de tout type de résine fond de moule, autre que des résines solventées, sur stratifiés réalisés en résines polyuréthane et quels que soient les modes d'application. This process was developed to allow, on the one hand, the attachment of any type of mold base resin, other than solvent-based resins, on laminates made of polyurethane resins and whatever the modes of application.

Dans un moule réalisé en un quelconque matériau (plâtre-bois-composite-tôle etc...) et sur lequel a été effectué un traitement anti-adhésif, on procède à la projection d'une résine de synthèse possédant incorporé, un renfort d'une part, et un élément susceptible de remonter en surface pour permettre de créer un effet d'isolement aux dégagements gênants de styrène ou autres, nuisant à l'accrochage ultérieur du stratifié polyuréthane. L'épaisseur de cette couche est fonction des caractéristiques à obtenir ainsi que du matériau utilisé. In a mold made of any material (plaster-wood-composite-sheet etc ...) and on which a non-stick treatment has been carried out, a synthetic resin is sprayed having incorporated, a reinforcement of on the one hand, and an element capable of rising to the surface to allow the creation of an isolation effect in the annoying releases of styrene or others, detrimental to the subsequent attachment of the polyurethane laminate. The thickness of this layer depends on the characteristics to be obtained as well as the material used.

Après polymérisation de la couche de surface, le temps de cette polymérisation étant directement lié aux matériaux ainsi qu'aux systèmes catalytiques utilisés, c procède à la projection ou à l'injection du polyuréthane suivant le procédé retenu. After polymerization of the surface layer, the time of this polymerization being directly linked to the materials as well as to the catalytic systems used, it proceeds to the spraying or the injection of the polyurethane according to the selected method.

Projection: On applique une première couche d'épai- seur variable suivant le composite à obtenir, de polyuré#thane convenablement dosé pour permettre l'élaboration d'un matériau homogène aux caractéristiques requises. Projection: A first layer of variable thickness is applied according to the composite to be obtained, of polyurea # thane suitably dosed to allow the production of a homogeneous material with the required characteristics.

On pose sur cette première couche, une armature constituée d'une grille tissée ou non tissée à mailles formant des figures géométriques, d'un espace suffisant pour être pénétrée par les couches ultérieures de résine polyuréthane. Cette grille pourra être en verre-aramidecarbone ou tout autre matériau minéral, végétal ou de synthèse. Un avantage sera obtenu en utilisant une grille auto-adhésive facilitant la mise en place. A reinforcement consisting of a woven or non-woven mesh grid forming geometrical figures is placed on this first layer, with a space sufficient to be penetrated by the subsequent layers of polyurethane resin. This grid may be made of aramid-carbon glass or any other mineral, vegetable or synthetic material. An advantage will be obtained by using a self-adhesive grid facilitating the installation.

Sur cet ensemble , on procède à l'application de la couche suivante en résine polyuréthane dans les mêmes conditions que précédemment. On this assembly, the next layer of polyurethane resin is applied under the same conditions as above.

Ces opérations de grille et de projection pourront être répétées autant de fois que nécessaire, pour obtenir un composite répondant aux caractéristiques requises. These grid and projection operations can be repeated as many times as necessary, to obtain a composite meeting the required characteristics.

Ce composite est ensuite déemoulé de sa forme support et usiné aux formes désirées. This composite is then removed from its support form and machined to the desired shapes.

Injection: Le procédé consistant à incorporer des renforts avant fermeture des moules et précédent l'injection des résines polyuréthane est déjà utilisé, l'originalité du Procédé décrit, consiste donc dans la possibilité d'obtenir un matériau par injection possédant en surface, le revêtement défini au chapitre du procédé " projection". Injection: The process consisting in incorporating reinforcements before closing the molds and preceding the injection of the polyurethane resins is already used, the originality of the Process described, therefore consists in the possibility of obtaining a material by injection having on the surface, the coating defined in the chapter on the "projection" process.

Ce composite peut satisfaire à la fabrication de "sandwich" par répétition des opérations dans des moules mâles ou femelles ultérieurement fermés et injectés de mousse de synthèse. This composite can satisfy the manufacture of a "sandwich" by repeating the operations in male or female molds subsequently closed and injected with synthetic foam.

L'empilage dupro#zéd# de projection, poursuivi par le collage de mousses ou tous autres matériaux; végétal, minéral ou de synthèse., suivi de la projection de résine de polyuréthane permettra d'obtenir également des "sandwich"équilibrés ou non. The stacking of the projection # zéd # projection, continued by the bonding of foams or any other materials; vegetable, mineral or synthetic., followed by the projection of polyurethane resin will also make it possible to obtain balanced or unbalanced sandwiches.

Le procédé est destiné à l'obtention de toutes pièces simple peau ou "sandwich", utilisables en industrie pièces uniques, petites, moyennes ou grandes séries, pièces à bonnes caractéristiques mécaniques dans des conditions d'élaboration particulièrement économiques.  The method is intended for obtaining all single skin or "sandwich" parts, which can be used in the industry of single parts, small, medium or large series, parts with good mechanical characteristics under particularly economical production conditions.
