Abstract

The invention relates to a PPR (polypropylene random copolymer) pipe with copper texture. The PPR pipe comprises, by weight, 100 parts of PPR, 15-30 parts of granular copper powder, 1-5 parts of flakycopper powder, 10-15 parts of dispersing agents, 8-18 parts of carbon fibers, 1-3 parts of coupling agents, 5-15 parts of soft-core hard-shelled core shell copolymer toughening agents and 1.3-3 partsof antioxidants. The PPR pipe has good copper texture and is good in low-temperature toughness, free from embrittlement and good in heat resistance.

Description

technical field [0001] The invention relates to a PPR pipe material with copper texture, belonging to the technical field of PPR pipe preparation. Background technique [0002] PPR is also called random copolymerized polypropylene, which is extruded into pipes by random copolymerized polypropylene, and the pipes are injection molded into pipe fittings. Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, PPR pipe fittings are energy-saving, material-saving, Environmental protection and non-toxic, heat and pressure resistance, light weight and high strength, corrosion resistance, no scaling, good impact resistance and creep resistance, easy installation, firm connection, long service life, recyclable materials, etc., are widely used in construction Water supply and drainage, city gas, electric power and optical cable sheathing, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and...
