Abstract

The subject of the present invention is a decoration method which consists in cracking metal powders, which are deposited on the back of a transparent panel, by spraying solvent and by blowing pressurised air, and then in covering them with a bottom layer (undercoat) in order to give the overall colour. The panels thus obtained are essentially intended for decoration and for coating (facing) furniture and articles.

Description

L'invention a pour objet un procédé de décoration de panneaux en matière plastique transparente et les panneaux décorés obtenus par la mise en oeuvre du procédé. The subject of the invention is a method of decorating panels of transparent plastic material and the decorated panels obtained by implementing the method.

Actuellement, les matériaux plastiques connaissent un grand développement dans la décoration. Ils sont généralement utilisés dans leur teinte d'origine, transparent, translucide, teinté dans la masse, avec un fond (miroir en polymétacrylate de méthyle), ou avec des inclusions. I1 existe aussi des procédés de décoration sur glace mais qui n'utilisent pas le procédé de craquelage. Currently, plastic materials are experiencing a great development in decoration. They are generally used in their original shade, transparent, translucent, tinted in the mass, with a background (mirror in polymethyl methacrylate), or with inclusions. There are also decoration methods on ice but which do not use the cracking process.

Le procédé, selon l'invention, consiste à nettoyer un panneau plastique, sur une face, a l'aide d'un solvant du type aromatique (par exemple l'acétate d'éthylglycol) qui peut être le meme que celui utilisé pour le dépôt des poudres et pour le craquelage). The method according to the invention consists in cleaning a plastic panel, on one side, using a solvent of the aromatic type (for example ethyl glycol acetate) which can be the same as that used for the deposit of powders and for cracking).

Toutes les opérations doivent se faire dans un local fermé exempt de particules en suspension qui pourraient, le cas échéant, se figer dans la peinture. All operations must be carried out in a closed room free of suspended particles which could, if necessary, freeze in the paint.

La température ambiante doit être proche de 20 degrés celcius et l'hygrométrie ne doit pas dépasser 80 degrés.The ambient temperature should be close to 20 degrees celcius and the humidity should not exceed 80 degrees.

Après le nettoyage, il est procédé au dépôt des poudres métalliques qui peuvent être l'or, l'argent, le cuivre, le bronze, etc... After cleaning, metallic powders, which may be gold, silver, copper, bronze, etc., are deposited.

Ces poudres peuvent être déposées a l'aérographe en les mélangeant a un solvant. L'aérographe permet en effet de bien contrôler le dessin ainsi que l'importance du dépôt. These powders can be deposited with an airbrush by mixing them with a solvent. The airbrush indeed allows to control the drawing as well as the importance of the deposit.

Immédiatement, on peut procéder au craquelage, par pulvérisation de solvant et par soufflage d'air sous pression (1 a 3 kg). La méthode, la quantité de solvant, ainsi que le soufflage, permettent une multitude d'effets que l'opEra- teur peut bien maîtriser. Immediately, cracking can be carried out, by spraying with solvent and by blowing air under pressure (1 to 3 kg). The method, the quantity of solvent, as well as the blowing, allow a multitude of effects that the operator can control well.

Après évaporation du solvant, l'opérateur peut appliquer une couche de fond, laquelle donne la couleur d'ensemble. Celle-ci peut éventuellement être craquelée par solvant de la même manière que précédemment et une deuxième couche de fond de couleur différente peut être appliquée. Ainsi, les couches de fond successives peuvent être de teintes différentes, celles-ci restant visibles a travers le craquelage. After the solvent has evaporated, the operator can apply a base coat, which gives the overall color. This can optionally be cracked by solvent in the same way as above and a second base coat of different color can be applied. Thus, the successive base layers can be of different colors, these remaining visible through the cracking.

I1 est à noter que des effets décoratifs différents peuvent être obtenus en passant d'abord une première couche de fond qui, dans ce cas, est un simple voile les poudres sont déposées immédiatement après, avec une quantité de solvant suffisante pour rediluer la première couche de peinture. Ainsi la poudre métallique apparalt sur le panneau. Après soufflage et séchage, il peut être déposé une deuxième couche de fond pour rendre le panneau opaque. It should be noted that different decorative effects can be obtained by first passing a first base layer which, in this case, is a simple veil, the powders are deposited immediately afterwards, with an amount of solvent sufficient to dilute the first layer. paint. Thus the metallic powder appears on the panel. After blowing and drying, a second base coat can be deposited to make the panel opaque.

La peinture utilisée peut etre un acrylopolyuréthane mélangée avec - un durcisseur (dosage selon prescription de la marque), - un diluant pour polyuréthane (20 à 30 Z), la dilution de la poudre dans le solvant est d'environ 10 à 20 g. par litre. The paint used can be an acrylopolyurethane mixed with - a hardener (dosage as prescribed by the brand), - a thinner for polyurethane (20 to 30%), the dilution of the powder in the solvent is approximately 10 to 20 g. per liter.

Après le séchage, il faut appliquer une couche de protection qui n'est pas nécessairement une peinture, mais un enduit, un film plastique, etc...After drying, apply a protective layer which is not necessarily a paint, but a coating, plastic film, etc.

Ce procédé est techniquement très intéressant, car il nécessite très peu d'investissement, d'autre part, le matériau plastique s'obtient et se découpe très facilement et n'est pas fragile. This process is technically very interesting, because it requires very little investment, on the other hand, the plastic material is obtained and cut very easily and is not fragile.

Le craquelage peut se réaliser sur des matériaux supports autres que le plastique, notamment le verre. Cracking can be carried out on support materials other than plastic, in particular glass.

Quant à l'application industrielle, ces panneaux décoratifs peuvent être utilisés en tant que tels, mais aussi pour l'habillage et la fabrication de meuble ainsi que pour la réalisation de divers autres objets. En effet, la matière est thermoformable et se prete tout à fait à ce genre d'utilisation.  As for the industrial application, these decorative panels can be used as such, but also for the dressing and the manufacture of furniture as well as for the realization of various other objects. Indeed, the material is thermoformable and lends itself perfectly to this kind of use.
