发明名称 COMPOSITION FOR MARBLE CHIP AND MANUFACTURING METHOD OF MARBLE CHIP
摘要 PURPOSE: A marble chip is provided to obtain high transparency while having same specific gravity and hardness as a base material of an artificial marble, to be evenly distributed within the artificial marble, and to obtain excellent sanding property of the marble chip. CONSTITUTION: A marble chip composition includes an epoxy resin, a glass frit, and a hardener. The content of the glass frit is 30~150 parts by weight based on 100.0 parts by weight of a non-halogen epoxy resin. The glass frit has a particle size of 0.15~1.4 mm. A method for manufacturing the marble chip for an artificial marble comprises the following steps: deaerating the marble chip composition using a vacuum deflator; putting the deaerated marble composition into a molding frame and hardening the composition by thermally treating the composition at 70~90 °C; and cooling the hardened marble chip composition and smashing the cooled composition.
