Definitions
- the present invention relates to a method for producing utility or decorative objects from a plastic sheet material, transparent or tinted in the mass or on the surface, of precise shape.
- the object of the invention is to propose a method for producing objects of the above type which have a completely original shape and appearance, without any limitation of shape, offering the artist total latitude in his creation. This process also makes it possible to produce parts which are all different from one another if desired.
- the heat source could be, for example but not limited to infrared radiation.
- a decorative object is thus obtained by deformation under the effect of heat, deformation which can be controlled and oriented for example by a mold.
- Example 1 at 53 °, after about 30 seconds, the acrylic materials lose their shine, become dull and curl up.
- Example 2 After about a minute, the first bubbles appear, the material puffs up. The phenomenon lasts for one to two minutes and then stabilizes when the entire surface is transformed. The bubbles burst as if the material was boiling.
- Example 2 at 53 °, the polycarbonates do not transform in the same way and no bubbles appear even for a very long time.
- Example 3 If one works at a higher temperature (75 °), the phenomenon is the same for acrylic and polycarbonates.
- a colored appearance is obtained by the basic colors of the material and by spraying with suitable colored varnishes.

Abstract
Description
La présente invention a pour objet un procédé pour la réalisation d'objets utilitaires ou décoratifs à partir d'un matériau plastique en feuille, transparent ou teinté dans la masse ou en surface, de forme précise.The present invention relates to a method for producing utility or decorative objects from a plastic sheet material, transparent or tinted in the mass or on the surface, of precise shape.
Il est connu de réaliser par diverses techniques des objets utilitaires ou décoratifs à partir de matériaux plastiques que l'on soumet à différents traitements mécaniques, par exemple découpe, polissage, etc...It is known to produce, by various techniques, utility or decorative objects from plastic materials which are subjected to different mechanical treatments, for example cutting, polishing, etc.
On entendra dans tout ce qui suit par "objets utilitaires ou décoratifs" des objets divers tels que, non limitativement :
- bijoux fantaisie,
- ornements de coiffure,
- tableaux
- sculptures,
- panneaux décoratifs.
- costume jewelry,
- headdress ornaments,
- paintings
- sculptures,
- decorative panels.
L'invention a pour but de proposer un procédé pour réaliser des objets du type ci-dessus qui aient une forme et une allure totalement originales, sans aucune limitation de formes, offrant à l'artiste une latitude totale dans sa création. Ce procédé permet également de réaliser des pièces toutes différentes l'une de l'autre si on le désire.The object of the invention is to propose a method for producing objects of the above type which have a completely original shape and appearance, without any limitation of shape, offering the artist total latitude in his creation. This process also makes it possible to produce parts which are all different from one another if desired.
Conformément à l'invention, on propose à cette fin un procédé pour la réalisation d'objets utilitaires ou décoratifs à partir d'un matériau plastique en feuille, transparent ou teinté dans la masse ou en surface, de forme précise, caractérisé en ce qu'il consiste à soumettre ledit matériau plastique à une ambiance humide avec contrôle du degré hygrométrique puis à le disposer sous une source de chaleur à une température supérieur à 53°.According to the invention, a method is proposed for this purpose for the production of utility or decorative objects from a plastic sheet material, transparent or dyed in the mass or on the surface, of precise shape, characterized in that 'it consists in subjecting said plastic material to a humid atmosphere with control of the hygrometric degree and then placing it under a heat source at a temperature above 53 °.
La source de chaleur pourra être par exemple mais non limitativement un rayonnement infra-rouge.The heat source could be, for example but not limited to infrared radiation.
On obtient ainsi un objet décoratif par déformation sous l'effet de la chaleur, déformation qui peut être contrôlée et orientée par exemple par un moule.A decorative object is thus obtained by deformation under the effect of heat, deformation which can be controlled and oriented for example by a mold.
On reprendra ci-après les essais réalisés.
Exemple 1 - à 53°, au bout d'environ 30 secondes, les matières acryliques perdent leur brillance, deviennent mates et se recroquevillent.The tests carried out will be repeated below.
Example 1 - at 53 °, after about 30 seconds, the acrylic materials lose their shine, become dull and curl up.
Au bout d'environ une minute, les premières bulles apparaissent, la matière se boursouffle. Le phénomène dure pendant une à deux minutes puis se stabilise quand toute la surface est transformée. Les bulles éclatent comme si la matière était en ébullition.
Exemple 2 - à 53°, les matières polycarbonates ne se transforment pas de la même façon et aucune bulle n'apparaît même pendant un temps très long.
Exemple 3 - Si l'on travaille à une température supérieure (75°), le phénomène est le même pour les matières acryliques et polycarbonates.After about a minute, the first bubbles appear, the material puffs up. The phenomenon lasts for one to two minutes and then stabilizes when the entire surface is transformed. The bubbles burst as if the material was boiling.
Example 2 - at 53 °, the polycarbonates do not transform in the same way and no bubbles appear even for a very long time.
Example 3 - If one works at a higher temperature (75 °), the phenomenon is the same for acrylic and polycarbonates.
Un aspect coloré est obtenu par les coloris de base de la matière et par la pulvérisation de vernis colorés appropriés.A colored appearance is obtained by the basic colors of the material and by spraying with suitable colored varnishes.
Ces objets à l'aspect esthétique particulier peuvent être assemblés entre eux ou à d'autres éléments de matériaux divers.These objects with a particular aesthetic appearance can be assembled together or with other elements of various materials.
Les effets de forme et de couleur n'auront de limite que dans la capacité créatrice de l'artiste. Les techniques de transformation se prêtent tout à fait à une fabrication répétitive quant aux formes et aspects visuels (séries industrielles) et également à l'objet unique personnalisé.The effects of form and color will only have limits in the creative capacity of the artist. The transformation techniques lend themselves perfectly to repetitive manufacturing in terms of forms and visual aspects (industrial series) and also to the unique personalized object.
