Abstract
An artificial marble using chips made of a low specific gravity material via a lamination or crunch technique to realize a natural stone-like texture, and a process for preparing the artificial marble are disclosed. In one example, a high specific gravity layer containing a high specific gravity inorganic filler is laminated on a low specific gravity layer made of a low specific gravity material to form a flat board, and then, the flat board is crushed to produce chips. In another example, low specific gravity regions made of a low specific gravity material is coated with a high specific gravity slurry containing a high specific gravity inorganic filler, to produce crunch chips. Thereby, a low specific gravity material, which could not be used conventionally, is applicable to the artificial marble, so as to achieve an outer appearance remarkably similar to a texture of natural marbles.
