RESOURCE RECOVERY METHOD OF POLYCARBONATE-BASED RESIN WASTE, PRODUCTION METHOD OF REGENERATED POLYCARBONATE-BASED RESIN MOLDED PRODUCT, AND REGENERATED POLYCARBONATE-BASED RESIN MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a regenerated polycarbonate-based resin, with physical properties and durability being improved, which is obtained from polycarbonate-based resin waste.SOLUTION: A resource recovery method of polycarbonate-based resin waste comprises: a step of adding, relative to 100 wt.% of polycarbonate resin waste, 0.1 wt.% or more and 20 wt.% or less of a compatibilizer comprising at least one functional group selected from an epoxy group, an oxazoline group and a maleic acid group, 0.05 wt.% or more and 1.0 wt.% or less of a carbodiimide compound and 1.0 wt.% or more and 5.0 wt.% or less of an acrylic elastomer to polycarbonate-based resin waste to obtain a mixture; a melt-mixing step of melt-kneading the mixture to obtain a melt mixture; and an extrusion-molding step of extrusion-molding the melt mixture by using a screen mesh having an opening size of 0.08 mm or more and 0.5 mm or less to obtain an extrusion-molded product.
