<p>PURPOSE: A synthetic clay composition is provided to add only a viscosity controlling agent to cork powder and a binder resin, thereby being economically manufactured. CONSTITUTION: A synthetic clay composition comprises 26-45 parts by weight of cork powder, 35-55 parts by weight of binder resin, 1-30 parts by weight of viscosity controlling agent, and 1-30 parts by weight of water. The cork powder additionally comprises 60wt% of cork powder with a particle diameter of 0.2-0.5 mm, and 60wt% of cork powder with a particle diameter of 2-3mm. The binder resin is one or more selected from a polyvinylalcohol-based group, a polyvinylacetate acryl copolymer resin group, and a polyacrylic resin group. The viscosity controlling agent is one or more selected from polyhydroxy alcohols, fatty acids, natural gums, and celluloses.</p> |
