preparation example Construction
[0077] The order of preparation and lamination of each flat plate is not limited to a specific manner, and each flat plate can be hardened by a generally used molding, pressing, vibrator, or UV curing method or the like.
[0078] Each of the high and low specific gravity layers may be in the form of a multilayer comprising two or more layers. For example, a single low specific gravity layer may be integrally formed with one to three high specific gravity layers.
[0079] Based on the selected size of the high specific gravity flakes, it is necessary to adjust the thickness of the high specific gravity and low specific gravity layers to prevent the separation of the high specific gravity layer and the low specific gravity layer during crushing.
[0080] If the slabs are prepared and laminated to each other, the laminated slabs are crushed to produce high specific gravity pellets. Therefore, artificial marble can be produced by using small pieces of high specific gravity.

[0100] A flat plate for forming a transparent low specific gravity layer was prepared by using an acrylic resin (specific gravity: 1.19, light transmittance: 95%), and then a flat plate for forming a high specific gravity layer (specific gravity: 3.175) was prepared by using a slurry, The slurry contained 100 parts by weight of acrylic resin and 150 parts by weight of barium sulfate as a high specific gravity filler (specific gravity: 4.499). Then, the high specific gravity layer flat plate is laminated on the transparent low specific gravity layer flat plate. By crushing the laminated flat plate, high specific gravity pellets are produced.
[0101] The specific gravity of the prepared high specific gravity flakes was 1.65. When 10 wt% of high specific gravity flakes are used to prepare artificial marble, the high specific gravity flakes and other substantially single-color flakes only show a slight difference in specific gravity of ±0.1, and the crushed flakes of high specif...

[0103] A transparent low specific gravity flat plate was prepared by using an acrylic resin (specific gravity: 1.19, light transmittance: 95%). Subsequently, the flat plate was crushed to prepare transparent low specific gravity pellets. Then, a flat plate for forming high-specific-gravity chips was prepared by mixing 110 parts by weight of transparent low-specific-gravity chips with a slurry (specific gravity: 3.175) containing 100 parts by weight of acrylic resin while adding a hardener and additives and 160 parts by weight of barium sulfate as a high specific gravity filler (specific gravity: 4.499). Then, the flat plate used to form the high-specific-gravity pellets is crushed to prepare high-specific-gravity crushed pellets.
[0104] The resulting high specific gravity crushed flakes had a specific gravity of 1.64. When 10 wt% of high specific gravity crushed flakes are used to prepare artificial marble, the high specific gravity crushed flakes and other substantially s...
