ACRYLIC PREMIX, ACRYLIC ARTIFICIAL MARBLE, AND PROCESS FOR PRODUCING THE SAME

WIPO Patent Application WO/1999/055633

A1

An acrylic premix comprising (A) 10 to 90 wt.% acrylic resin composition comprising (a1) a monofunctional acrylic monomer, (a2) at least one of a polyfunctional acrylic monomers represented by general formulae (I to IV), and (b) an acrylic polymer, (B) 10 to 90 wt.% inorganic filler, and (C) a hardener in an amount of 0.01 to 10 parts by weight per 100 parts by weight of the sum of the components (A) and (B); and an acrylic artificial marble made using the premix and a process for producing the marble. The premix is useful for providing acrylic SMC or BMC which are satisfactory in high-temperature moldability, moldability, suitability for thickening, and storage stability. In (I), R¿1? is -H or CH¿3?; and k is 3 to 30. In (II), l and m each is 0 to 25, provided that l+m is 2 to 25. In (III), n is 2 to 25. In (IV), R¿2? to R¿5? each is C¿1-10? alkylene; and p, q, and r each is 0 to 10, provided that p+q+r is 2 to 25.
