Abstract
The present invention relates to a composition for manufacturing artificial marble including a first preliminary composition and a second preliminary composition which include an acrylic-based monomer, an acrylic-based resin, a polymerization initiator, a crosslinking agent, a coloring agent, and a gelling agent and have a viscosity of 100,000 Ps to 5,000,000 Ps and/or a storage modulus of 100,000 Pa to 1,000,000 Pa. A viscosity of the second preliminary composition is higher than a viscosity of the first preliminary composition. Coloring agents of the first preliminary composition and the second preliminary composition have different colors. A weight ratio of the first preliminary composition to the second preliminary composition is in a range of 1:1 to 500:1. According to the present invention, artificial marble having a dashed pattern similar to that of natural marble is provided by increasing viscoelasticity to prepare semi-solid preliminary compositions for manufacturing artificial marble, having excellent workability and machinability, preparing a composition for manufacturing artificial marble by mixing two or more of the semi-solid preliminary compositions, and performing v…
