Marbel chip having multi-layered structure, method for preparing double layered marble chip and artificial marble containing marble chip having multi-layered structure

摘要

PURPOSE: A marble chip having a multi-layered structure is provided to impart discriminated patterns compared with existing artificial marble by manufacturing artificial marble having specific patterns. CONSTITUTION: A marble chip having a multi-layered structure includes the marble chip coated with slurry for making artificial marble. A weight ratio of the marble chip to the slurry is 2 :1 - 8 : 1, respecitively. The slurry for a coating layer comprises 100 parts by weight of an acrylic resin or unsaturated polyesther-based resin syrup, 100 - 200 parts by weight of inorganic filler, 0.1 - 10 parts by weight of cross-linking agents, and 0.1 - 10 parts by weight of polymerization initiators.
