PASTE COMPOSITION FOR ARTIFICIAL MARBLE AND METHOD OF MANUFACTURING ARTIFICIAL MARBLE USING THE SAME

摘要

The present invention relates to a paste compsotion for artificial marble and a method of manufacturing the artificial marble using the same, which can solve the problems of efflorescence and durability in the existing cementitious marble and the problems of thermal resistance and acid tolerance in the existing organic binder-based marble, and can provide an insulating function to the artificial marble by using an inorganic binder such as an amorphous activated aluminosilicate compound and also using a lightweight particulate porous inorganic material. The method of manufacturing the artificial marble includes preparing paste for artificial marble by mixing 10~20 parts by weight of white cement, 3~10 parts by weight of amorphous activated aluminosilicate, 40~70 parts by weight of broken-stone chip, 5~10 parts by weight of water, 0.1~1 part by weight of water-reducing agent and 10~30 parts by weight of lightweight particulate porous inorganic material; pouring and vibration-molding the paste in a mold; curing the paste; inducing a hydrothermal reaction of cured artificial marble at high temperature and high pressure; and machining cured product.
