Abstract

The invention relates to a high and low temperature resistant PPR (Polypropylene Random) pipe with an aluminum metal effect. The PPR pipe is prepared from the following components in parts by weight:100 parts of PPR, 10 to 25 parts of aluminite powder, 8 to 18 parts of dispersing agent, 3 to 8 parts of soft-core hard-shell type core-shell copolymer, 5 to 10 parts of butadiene styrene rubber, 5 to10 parts of carbon fiber, 3 to 8 parts of aciform wollastonite fiber, 1 to 3 parts of coupling agent, and 1.5 to 3 parts of antioxygen. The PPR pipe provided by the invention has a uniform aluminum metal effect, good low-temperature toughness and good heat resistance.

Description

technical field [0001] The invention relates to a high and low temperature resistant PPR pipe with aluminum metal effect, which belongs 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 co...
