According to a second embodiment of the present invention, each high specific gravity small pieces can comprise: the high specific gravity zone that forms by the high specific gravity material, to have the proportion higher than background area proportion; And the low-gravity zone that forms by low specific gravity material, having the proportion lower than background area proportion, and this low-gravity zone can be uniformly distributed in high specific gravity zone as a setting.
In the present invention, because high specific gravity material (have 2.0 or higher proportion) is added in the low specific gravity material (have 0.2～2.0 proportion), this artificial marble can by use have to be included in artificial marble in the high specific gravity small pieces of the similar proportion of small pieces of solid color substantially prepare.
The high specific gravity small pieces mean by will the high specific gravity filler adding the small pieces that obtain in the low specific gravity material, thus obtain to be included in artificial marble in the similar proportion of small pieces proportion of solid color substantially.
The present invention proposes to give the low specific gravity material high specific gravity by lamination or crushing technology.Particularly, the low specific gravity layer that is made by low specific gravity material and the high specific gravity layer that is made by the high specific gravity material can be by laminations and monoblock type forms, perhaps the low-gravity zone can be contained the height ratio heavy sizing of high specific gravity filler by the coating of crushing technology, so that the small pieces of preparation crushing shape.Use lamination or crushing technology, can give low specific gravity material, thereby eliminate and the different problem of artificial marble proportion of using the high specific gravity small pieces high specific gravity.
