Method for manufacture of Pipe from polyvinly chloride resin molding composion

摘要

The purpose of the present invention is to provide a method for preparing a hardened polyvinyl chloride resin pipe which improves mechanical properties such as tensile strength, flexural rigidity, and long term water pressure resistance by using a polyvinyl chloride resin molding composition containing an additive which improves the degree of polymerization of polyvinyl chloride. The present invention prepares a hardened polyvinyl chloride resin pipe using a molding composition consisting of: with respect to 100 parts by weight of a polyvinyl chloride resin; 0.5-5 parts by weight of an UV/EV curing resin; 5-10 parts by weight of an impact reinforcing agent; 0.1-10 parts by weight of calcium carbonate; 3-7 parts by weight of a stabilizer; and 0.1-5 parts by weight of a processing material.
