   On se réfère à la   fig.l :   
La plaque réalisée en marbre artificiel comporte : un mélange d'une unité de sable avec une unité de ciment fondu et 10 à   15     %   de couleru, ce mélange étant coulé dans la masse constituée de deux unités de gravier rivière et une unité de ciment fondu, une face plongée dans un bain d'huile de lin, l'autre face brute imperinéavbilisée par une résine polyester. 



   L'ensemble est coulé dans un moule monté en verre ou polyester qui permet d'obtenir d'office au démoulage, l'aspect, le fini et le poli du marbre naturel ainsi que les teintes les plus variées. 



   Le refroidissement du moule se fait par eau. 



   Le séchage a une durée d'environ deux jours suivant l'épaisseur et le volume à traiter.

  "ARTIFICIAL MARBLE AND ITS MANUFACTURING PROCESS"
The invention relates to artificial marble and its manufacturing process comprising a mixture of a unit of sand with a unit of molten cement and 10 to 15% color, this mixture being poured into the mass consisting of two units of river gravel. and a unit of molten cement, the whole being poured into a water-cooled glass or polyester mold and dried for about two days., one side is then immersed in a bath of linseed oil, the other raw side waterproof. - bilised by a polyester resin.

The invention will be well understood by referring to the following description, given by way of non-limiting example and to the accompanying drawings in which;
Fig. 1, perspective view, an artificial marble slab according to the invention.



   Fig. 2 a sectional view through the artificial marble slab ..,
Fig. 3 shows an isometric perspective view of an object such as an ashtray made of artificial marble consisting of its various components and obtained by means of the method according to the invention.



   We refer to fig.l:
The slab made of artificial marble comprises: a mixture of one unit of sand with one unit of molten cement and 10 to 15% of couleru, this mixture being poured into the mass consisting of two units of river gravel and one unit of molten cement , one side immersed in a bath of linseed oil, the other raw side imperinéavbilisée by a polyester resin.



   The whole is cast in a mold mounted in glass or polyester which automatically produces the appearance, finish and polish of natural marble, as well as the most varied shades, upon release.



   The mold is cooled by water.



   The drying lasts about two days depending on the thickness and the volume to be treated.



  Although the invention has been described with regard to a particular embodiment, it is understood that it is in no way limited thereto and that various modifications of form and percentage in the composition can be made without having to that to move away from the framework and the spirit of the invention

Claims

1. - Artificial marble and its manufacturing process characterized in that it comprises a mixture of a unit of sand with a unit of molten cement and 10 to 15% color, this mixture being poured in the mass <Desc / Clms Page number 3> reconstituted, which while offering a relatively similar material, nevertheless show complex implementations and manufacturing processes which call for an elaborate technique, such as die-cast molds. These molds under pressure being brought to a certain temperature ;, requires special monitoring due to the various elements.

Consequently, such installations require relatively specialized labor, as does the frequent renewal of the molds used, which entails relatively high costs due to the cost of labor and the installation of the devices. the aforementioned .. - The present invention aims to remedy all the drawbacks of the aforementioned materials and processes and to provide a more resistant artificial marble and its manufacturing process making it possible to automatically obtain the appearance, the finish from the mold. and the polishing of natural marble without grinding and without polishing, by casting in a glass or polyester mold at normal temperature, therefore without the intervention of pressure and heat.

The final form in which the artificial marble is obtained obviously allows the realization of a wide variety of objects without dimensional limit, of varied appearance and colors and allows the most complex shapes and executions with means for fixing provided for. origin.

Finally, the artificial marble benefits from total waterproofing by a linseed oil bath on one side and by an application of polyester resin on the other raw side. It follows from these various criteria that, under these particularly advantageous working conditions, the cost of artificial marble and its mold are relatively low and the price of artificial marble in particular is much cheaper than natural marble and makes it possible to compete with materials. .

To this end, the invention relates to artificial marble and its manufacturing processcharacterized in that it comprises a mixture of a unit of sand with a unit of molten cement and 10 to 15% of color .. this mixture being poured into the mass consisting of two units of river gravel and one unit of molten cement, the whole being poured into a water-cooled glass or polyester mold and dried for approximately two days, one side is then immersed in a bath of linseed oil, the other raw side waterproofed with a polyester resin.

@ <Desc / Clms Page number 4> made up of two river gravel units and one unit of molten cement, one side immersed in a bath of linseed oil, the other raw side waterproofed by a polyester resin, poured into a water-cooled and dried glass or polyester mold for about two days.

2. - Artificial marble according to claim 1 characterized in that it can be made of refractory material and withstand a temperature. of more than 1,500 celciua.

3. - Artificial marble according to claim 1 characterized in that it comprises 10% to 15 had color, giving it the most varied colors and appearances.

4. - Artificial marble according to claim 1 characterized in that it can be reinforced in the mass and therefore have very good impact resistance.

5. - Artificial marble according to claim 1 characterized in that it comprises a polyester resin on the outside providing it with waterproofing {surface.

6. - Artificial marble according to claims 1 to 5 characterized in that it may comprise a polyester resin cast in the mass ensuring it a total waterproofing.

7. - Artificial marble and its manufacturing process according to claim 1 characterized in that it does not require any grinding or polishing being obtained in the final form. - @ 8. - Artificial marble and its manufacturing process according to claim 1 characterized in that they may include original orifices or means for fixing. @
