<p>PURPOSE: A manufacturing method of sound-absorbing panel is provided to reuse waste artificial marble as a high value added panel by mixing crushed materials and dusts of the waste artificial marble, expanded vermiculite and pearlite with acrylic resin syrup. CONSTITUTION: The manufacturing method of sound-absorbing panel includes following steps.(i) Crushed materials of the waste artificial marble of 25-35 weight%, expanded vermiculite of 12-32 weight%, perlite of 1-10 weight%, dusts of the waste artificial marble of 3-7 weight%, calcium phosphate of 12.99=17.95 weight% and acrylic resin syrup of 12.8-32 weight% 'containing(meta) acrylate monomer and the poly(meta) acrylate' are mixed.(ii) The mixture is put into a fixed frame and heat-treated with a high pressure at a temperature of 50-250°C.</p> |
