MANUFACTURING METHOD FOR HIGH QUALITY RECYCLED PC-ABS USING WASTE PLASTIC

摘要

PURPOSE: A manufacturing method of recycled PC-ABS is provided to obtain PC-ABS with the same physical properties as virgin PC-ABS and to prevent a peeling phenomenon by mixing and melting waste PC and waste ABS. CONSTITUTION: A manufacturing method of recycled PC-ABS comprises an ABS copolymer resin from waste styrene-acrylonitrile copolymer resin, butadiene-based additives, and waste PET(S20); a step of manufacturing the recycled PC-ABS resin using the recycled ABS resin and waste polycarbonate resin(S30). The first step comprises a step of adding 0.1-5 wt% of one of oxidant, dispersant, and dye; and a step of mixing and extruding the raw material.
