Abstract

Material for the production of descriptive panels, name plates or industrial panels, characterised in that it consists of a polymethyl methacrylate (PMMA) panel, onto one face of which is applied an original coating constituting the base (background) colour, specifically an acrylic resin mixed with a solvent.

Description

La présente invention a pour objet un matériau destiné à la réalisation de plaques signalétiques, patronymiques ou industrielles. The present invention relates to a material intended for the production of nameplates, patronymic or industrial.

De manière usuelle, les plaques de ce type sont réalisées 'actuellement par gravure sur matériaux métalliques, synthétiques, en général thermoplastiques (Méthacrylique). Dans cette derniere hypothèse, on applique au dos des plaques une peinture constituant la couleur de fond de la plaque. Ensuite la plaque est gravée et on applique une peinture pour colorer la gravure puis une couche de finition, ce travail étant effectué par le graveur. Usually, plates of this type are currently produced by etching on metallic, synthetic, generally thermoplastic (methacrylic) materials. In the latter hypothesis, a paint is applied to the back of the plates constituting the background color of the plate. Then the plate is engraved and a paint is applied to color the engraving then a finishing layer, this work being carried out by the engraver.

Les résultats obtenus sont imparfaits. The results obtained are imperfect.

Tout d'abord les solvants présents dans la plupart des peintures utilisées pour colorer la gravure sont tres agressifs et détériorent souvent la peinture précédemment appliquée constituant la couleur de fond de la plaque. First of all the solvents present in most of the paints used to color the engraving are very aggressive and often deteriorate the paint previously applied constituting the background color of the plate.

Par ailleurs, les peintures en question sont relativement fines et tendres, et peuvent donc être rayées malencontreusement en cours d'usinage. Furthermore, the paints in question are relatively fine and tender, and can therefore be scratched inadvertently during machining.

Enfin, ces mêmes matériaux ont une réaction importante aux contraintes thermiques mécaniques et aux conditions extérieures (alternances des conditions climatiques et de température). Finally, these same materials have an important reaction to mechanical thermal stresses and external conditions (alternating climatic and temperature conditions).

Le besoin se fait donc sentir d'un matériau qui ne présente pas ces différents inconvénients. There is therefore a need for a material which does not have these various drawbacks.

Conformément à l'invention, on propose à cet effet un matériau pour la réalisation de plaques signalétiques, patronymiques ou industrielles, caractérisé en ce qu'il consiste en une plaque en polyméthacrylate de méthyle (PMMA) sur l'une des faces de laquelle est appliquée un revêtement original constituant la couleur de fond de la plaque. According to the invention, a material is proposed for this purpose for the production of nameplates, patronymic or industrial, characterized in that it consists of a plate of polymethyl methacrylate (PMMA) on one of the faces of which is applied an original coating constituting the background color of the plate.

Selon un mode préféré de mise en oeuvre, la couche de couleur du fond sera une résine acrylique mélangée à un solvant. According to a preferred embodiment, the background color layer will be an acrylic resin mixed with a solvent.

Selon un autre mode de mise en oeuvre, la couche de couleur sera protégée par une couche de protection constituée d'un mélange polymere-monomère (c'est-à-dire polyméthacrylate-méthacrylate liquide), dit "GEL-COAT" qui polymérise et durcit. According to another embodiment, the color layer will be protected by a protective layer consisting of a polymer-monomer mixture (that is to say liquid polymethacrylate-methacrylate), known as "GEL-COAT" which polymerizes and hardens.

On ne sortirait pas du cadre de l'invention en combinant les deux courbes par l'utilisation d'une couche unique de "GEL-COAT" teinté.  It would not depart from the scope of the invention to combine the two curves by the use of a single layer of tinted "GEL-COAT".

De nombreux produits peuvent être utilisés, mais de préférence le PMMA sera du type commercialisé SOU6- la marque Altuglas (Altuglas est une marque déposée par la Société CDF Chimie). Many products can be used, but preferably PMMA will be of the marketed type SOU6- the Altuglas brand (Altuglas is a brand registered by the CDF Chimie Company).

La résine acrylique servant de couche de base est en elle-meme transparente. The acrylic resin serving as a base layer is in itself transparent.

Les teintes argentées et dorées sont obtenues par addition de poudres. The silver and golden shades are obtained by adding powders.

Les autres teintes sont obtenues à partir de pâtes concentrées. The other colors are obtained from concentrated pastes.

Les plaques ainsi préparées sont usinées par le graveur, par fraiseuses à pantographe ou à commande numérique. The plates thus prepared are machined by the engraver, by pantograph milling machines or by numerical control.

La fraise découpe dans la couche de fond les inscriptions destinées à être lues à travers la plaque de PMMA transparente. Ces inscriptions sont colorées et donnent ainsi un contraste par rapport à la couleur de fond. The cutter cuts in the base layer the inscriptions intended to be read through the transparent PMMA plate. These inscriptions are colored and thus give a contrast with the background color.

Le choix des matériaux précités apporte de nombreux avantages par rapport aux produits de l'art antérieur. The choice of the aforementioned materials brings many advantages compared to the products of the prior art.

Tout d'abord, ce revêtement de "GEL COAT" est absolument résistant à n'importe quel solvant présent dans la plupart des peintures qui serviront à la coloration de la gravure ou de la couche de finition appliquée en dernier lieu par le fraiseur,
De plus, le revêtement "GEL COAT" a une résistance aux rayures incomparable aux peintures jusqu'alors utilisées et évite donc le recommencement de la gravure sur une plaque qui aurait été rayée lors de l'usinage.First of all, this coating of "GEL COAT" is absolutely resistant to any solvent present in most of the paints which will be used for coloring the engraving or the finishing layer applied last by the miller,
In addition, the "GEL COAT" coating has an incomparable resistance to scratches to paints previously used and therefore avoids the repetition of engraving on a plate which would have been scratched during machining.

Enfin, celui-ci a une réaction aux contraintes thermiques mécaniques et aux conditions extérieures de même ordre que le support PMMA transparent constituant lui-même plus des 9/lOè du produit fini. Ce revêtement épouse donc parfaitement les réactions de la plaque ce qui évite fissures et vieillissement prématuré. Finally, it reacts to mechanical thermal stresses and to external conditions of the same order as the transparent PMMA support, itself constituting more than 9/10 of the finished product. This coating therefore perfectly matches the reactions of the plate which prevents cracks and premature aging.

Le matériau de l'invention trouve une application intéressante pour les plaques signalétiques, patronymiques, professionnelles (médecins, avocats, professions libérales, etc...), la signalisation de tous ordres notamment à l'intérieur des bâtiments hôpitaux, mairie, etc...), pour la signalisation également utilisée dans d'autres domaines (armoire électrique, tableaux synthétiques, plaques funéraires, etc).  The material of the invention finds an interesting application for nameplates, patronymic, professional (doctors, lawyers, liberal professions, etc.), signaling of all kinds, particularly inside hospital buildings, town hall, etc. ..), for signaling also used in other fields (electrical cabinet, synthetic tables, funeral plaques, etc.).
