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 (30)

1. A composition, comprising:

a polymer resin comprising at least one of a methylmethacrylate monomer, nanosilica, alumina trihydrate, azobisisobutyronitrile, ethylene glycol dimethacrylate, polymethylmethacrylate material and Stearic acid;

a stone gravel bit blended with the polymer resin,

wherein the mixture of polymer resin with the stone gravel bit is processed to produce the synthetic marble composition through an autoclave polymerization of the mixture that is castin a casting cell 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;

wherein methylmethacrylate monomer comprises 90%-100% of the mixture by weight,

wherein nanosilica comprises 0.05%-0.15% of the mixture by weight,

wherein alumina trihydrate comprises 0.05%-0.15% of the mixture by weight,

wherein azobisisobutyronitrile comprises 0.002%-0.015% of the mixture by weight,

wherein ethylene glycol dimethacrylate comprises 0.005%-0.015% of the mixture by weight, and

wherein stearic acid comprises at 0.005%-0.02% of the mixture by weight.

2. The composition of claim 1 :

wherein a mold is prepared to form a casting cell,

wherein air bubbles are removed from the mixture of polymer resin with the stone gravel bit to enhance a physical property of the synthetic marble material,

wherein the mixture is cast in the casting cell,

wherein the synthetic marble sheet is cured in an oven at a temperature of at least 100° C., and

wherein the product is separated from the casting cell.

3. The composition of claim 1 :

wherein the stone gravel bit is chosen from at least one of a group comprising a marble, a granite, and a basalt stone.

4. The composition of claim 1 :

wherein the composition is resistant to marking such that when a liquid is spilled on the composition a stain will not be left.

5. The composition of claim 1 :

wherein the composition is resistant to bacteria and micro-organismic growth because the surface of the composition has relatively low porosity.

6. The composition of claim 1 :

wherein the composition has high flexibility during formation processes, making it easier to be shaped than natural marble, with negligible loss during making.

7. The composition of claim 1 :

wherein the composition may be different colors because of the different color properties of the stone gravel bit blended with the polymer resin.

8. The composition of claim 1 :

wherein the composition is durable to heavy weights without cracking because of its relatively high tensile strength.

9. The composition of claim 1 :

wherein the composition has higher thermal insulation properties than natural marble because of the composition's lower thermal conductivity than marble.
