Abstract

A method of producing a synthetic composition having properties of marble includes blending a polymer resin with a stone gravel bit to form a mixture. The method also includes processing the mixture of polymer resin with the stone gravel bit to produce a synthetic marble composition through a polymerization of the mixture that is cast in a casting cell. Further, the method may include preparing a mold to form a casting cell, removing air bubbles from the mixture of polymer resin with the stone gravel bit to enhance a physical property of the synthetic marble material, casting the mixture in the casting cell, polymerizing the cast mixture through an autoclave polymerization of the mixture at a pressure ranging from 1 to 10 atmospheres and a temperature ranging from 50° to 100° C. to prepare the synthetic marble material composition, and curing the synthetic marble sheet in an oven.

Claims (20)

1. A method, comprising:

blending a polymer resin with a stone gravel bit to form a mixture;

processing the mixture of a polymer resin with the stone gravel bit to produce a synthetic marble composition through a polymerization of a mixture that is cast in a casting cell;

producing a synthetic composition having at least a physical property of marble, comprising:

preparing a mold to form a casting cell;

removing air bubbles from the mixture of a polymer resin with the stone gravel bit to enhance a physical property of the synthetic marble material;

casting the mixture in the casting cell;

polymerizing the cast mixture through an autoclave polymerization of the mixture at a pressure ranging from 1 to 10 atmospheres and a temperature ranging from 50° to 100° C. to prepare the synthetic marble material composition;

curing the synthetic marble sheet in an oven at a temperature of at least 100° C.; and

separating a product from the casting cell;

processing the mixture with the stone gravel bit comprising 40% to 60% of the mixture by weight;

processing a mixture of polymer resin with the stone gravel bit with methylmethacrylate monomer comprising 90%-100% of the mixture by weight, nanosilica comprising 0.05%-0.15% of the mixture by weight, alumina trihydrate comprising 0.05%-0.15% of the mixture by weight, azobisisobutyronitrile comprising 0.002%-0.015% of the mixture by weight, and ethylene glycol dimethacrylate comprising 0.005%-0.015% of the mixture by weight, and stearic acid comprising 0.005%-0.02% of the mixture by weight;

blending the stone gravel bit with a polymer resin comprising at least one of a methylmethacrylate monomer, a nanosilica, an alumina trihydrate, an azobisisobutyronitrile, an ethylene glycol dimethacrylate, a polymethylmethacrylate material, and a Stearic acid;

preparing the mold from a group comprising teflon and glass;

forming the casting cell with a first portion and a second portion of glass plate from a group comprising a tapered glass plate and a reinforced glass plate;

separating the first portion of glass plate from the second portion of glass plate with a gasket;

ensuring the width of the gasket is substantially similar to the desired thickness of the sheet of the synthetic marble composition; and

creating the gasket from polyvinyl chloride.

2. The method of claim 1 , blending the polymer resin with the stone gravel bit in a vacuum in order to avoid existence of the air bubbles.

3. The method of claim 1 , selecting the stone gravel bit from at least one of a group comprising a marble, a granite, and a basalt stone.
