COMPOSITION OF POLYETHYLENE COMPOUNDS FOR SEWER PIPE

摘要

PURPOSE: A recycled polyethylene resin composition for a drain pipe having improved pressure resistance and safety is provided to prevent the environmental contamination by recycling resources. CONSTITUTION: A recycled polyethylene resin composition for a drain pipe contains the following: 100 parts of recycled high-density polyethylene resin by weight; 3-20 parts of high density polyethylene master batch by weight containing carbon black; 0.01-0.1 parts of phenol based antioxidant by weight; 0.15-12 parts of UV stabilizer by weight; and 0.5-3 parts of cross-linking agent by weight. The cross-linking agent is a linear low-density polyethylene or polypropylene based adhering resin grafted with maleic anhydride.
