Abstract

Method of moulding by casting by means of a filled polyester resin. The invention relates to a technique which employs a filled polyester resin, irrespective of the volume or the shape of the component to be obtained by moulding. The principle resides in the metering of the accelerators and catalysts and, above all, in the addition to this mixture of a filler (glass frit, sand, silica, etc) intended to moderate and to control the polymerisation reaction of the filled polyester resin. The method according to the invention is particularly intended for the manufacture of light fittings or of any other article which may or may not be related to lighting, irrespective of its shape or its volume.

Description

Ce procédé est utilisable en particulier pour réaliser des luminaires, ou objets décoratifs lumineux ou non, du mobilier (tables...) des panneaux lumineux ou non en vue de décorer les sols, les plafonds où les murs, ou tous autres objets de toutes dimensions (presse-papier publicitaire...) les techniques employées précédement ne permettaient pas de mettre en oeuvre de grandes quantités de résine en une seule coulée pour des problèmes de réaction très violente au cours de la polymérisation (température très élevée, fissurage de la résine etc...)
La solution apportée par cette invention, consiste d'une part dans le dosage des produits réactifs tels que l'accélérateur et le catalyseur, et surtout dans le choix des matériaux constituant une charge apportée à la résine au moment du coulage dans le moule.Pour l'application au luminaire, cette charge sera essentiellement constituée de verre pilé, dont la proportion variera en fonction du calibrage de ce verre et de la transparence à obtenir.
This process can be used in particular to make luminaires, or decorative objects whether or not luminous, furniture (tables, etc.) with luminous or non-luminous panels in order to decorate floors, ceilings or walls, or any other object of all dimensions (advertising paperweight ...) the techniques used previously did not allow large amounts of resin to be used in a single pour for very violent reaction problems during polymerization (very high temperature, cracking of the resin etc ...)
The solution provided by this invention consists on the one hand in the dosing of reactive products such as the accelerator and the catalyst, and especially in the choice of materials constituting a filler brought to the resin at the time of casting in the mold. application to the luminaire, this charge will essentially consist of crushed glass, the proportion of which will vary according to the calibration of this glass and the transparency to be obtained.

Si l'aspect transparent n'est pas utile, cette charge pourra etre constituée de matière minérale tel que le sable, la silice ou autre. Le choix et le dosage des colorants utilisées contribuent également à controler l'intensité de la réaction de polymérisation et également à donner un aspect final translucide ou opaque. Les moules utilisés sont de plusieurs types.If the transparent aspect is not useful, this filler can be made up of mineral matter such as sand, silica or other. The choice and dosage of the dyes used also help to control the intensity of the polymerization reaction and also to give a final translucent or opaque appearance. The molds used are of several types.

I - le stratifié de polyester, préalablement enduit d'une couche de cire de démoulage et après séchage de celle-ci, d'une couche de Gelcoat, ayant pour but d'assurer un enrobage complet de la pièce à couler, à la fois fin et résistant. I - the polyester laminate, previously coated with a layer of mold release wax and after drying thereof, with a layer of Gelcoat, intended to ensure complete coating of the part to be cast, both thin and resistant.

2 - le moule en fonte d'aluminium utilisé surtout pour les grandes séries, il ne nécessite aucun démoulant et offre en outre une meilleure dissipation de la chaleur au moment de la polymérisation de la résine et un meilleur état de surface de la pièce produite. 2 - the cast aluminum mold used especially for large series, it does not require any release agent and also offers better heat dissipation during the polymerization of the resin and a better surface finish of the part produced.

3 - le moule en élastomère silicone, offrant la possibilité particulière de pouvoir reproduire des formes très complexes avec très grande fiabilité. 3 - the silicone elastomer mold, offering the special possibility of being able to reproduce very complex shapes with very high reliability.

4 - d'autres matériaux sont utilisables selon les besoins, par exemple : le verre, le bois, le polyQth#lène etc. 4 - other materials can be used as required, for example: glass, wood, polyQth # lene etc.

La mise en oeuvre du moulage est la suivante
10) étalage d'une couche de cire à démouler si nécessaire suivant le type de moule puis séchage.
The implementation of the molding is as follows
10) spreading of a layer of demolding wax if necessary depending on the type of mold, then drying.

20) recouvrir l'intérieur du moule d'une fine couche de gelcoat polyester et attendre le durcissement complet.  20) cover the inside of the mold with a thin layer of polyester gelcoat and wait for complete hardening.

30) fermer le moule de façon étanche et le remplir de la charge choisie (dans le cas d'objets translucides'la charge constituée de verre pilé)
Pour Pourl'application au luminaire, une cavité centrale sera créée au moment de remplir le moule de verre pilé, par une pince réalisée en élastomère de silicone incorporée au centre du moule, et aura pour but, après démoulage, d'accueillir une ampoule électrioue, de préférence fluorescente.
30) close the mold tightly and fill it with the chosen charge (in the case of translucent objects, the charge made of crushed glass)
For the application to the luminaire, a central cavity will be created at the time of filling the mold with crushed glass, by a clamp made of silicone elastomer incorporated in the center of the mold, and will aim, after demolding, to accommodate an electric bulb , preferably fluorescent.

40) couler le mélange : résine polyester d'inclusion, d'accélérateur, colorant, catalyseur, dans les proportions calculées suivant le volume, puis attendre la polymérisation complète. 40) pour the mixture: polyester resin of inclusion, accelerator, dye, catalyst, in the proportions calculated according to the volume, then wait for complete polymerization.

5 ) démoulage par ouverture du moule. 5) demolding by opening the mold.

6 ) ponçage. 6) sanding.

7 ) vernissage.  7) varnishing.
