Abstract
An artificial silica marble comprises a matrix and a line pattern portion. The line pattern portion comprises fine lines having a width of about 50 to about 500 μm and forms a web- or net-like pattern. The line pattern portion divides or partitions the artificial silica marble into a plurality of irregularly shaped pattern portions to form an amorphous pattern in the cross section of the artificial silica marble.
Claims13
An artificial silica marble comprising a matrix and a line pattern portion, wherein the line pattern portion comprises fine lines having a width of about 50 to about 500 μm and forming a web- or net-like pattern, wherein the line pattern portion divides the artificial silica marble into a plurality of irregularly shaped pattern portions to form an amorphous pattern in the cross section of the artificial silica marble.
A method for preparing an artificial silica marble having an amorphous pattern, the method comprising the steps of:
- (a) dry-mixing a silica powder, a silica sand and a first coloring pigment to prepare a first pigment-containing mixture;
- (b) wet-mixing an unsaturated polyester resin with the first pigment-containing mixture to prepare a first mixture of the artificial silica marble;
- (c) crushing the first mixture of the artificial silica marble;
- (d) dispersing a second pigment-containing mixture including a silica powder, a silica sand and a second coloring pigment in the crushed first mixture of the artificial silica marble to prepare a second mixture of the artificial silica marble;
- and
- (e) molding the second mixture of the artificial silica marble.
An artificial silica marble including a matrix and a line pattern portion, the artificial silica marble comprising:
- (A) about 5 to about 15% by weight of an unsaturated polyester resin;
- (B) about 20 to about 35% by weight of a silica powder having a particle diameter of about 10 to about 45 μm;
- (C) about 48 to about 73% by weight of a silica sand having a particle diameter of about 0.1 to about 5.6 mm, and
- (D) about 0.01 to about 2.0% by weight of coloring pigments.
