Abstract

The invention discloses a flame-retardant and wear-resistant polypropylene pipe. The pipe is prepared from, by weight, 95-100 parts of random copolymerization polypropylene, 9-12 parts of liquid polysulfide rubber, 5-9 parts of ethylene-vinyl acetate copolymer, 3-4 parts of styrene-butadiene thermoplastic elastomer, 17-20 parts of kaolin, 15-18 parts of organic bentonite, 7-10 parts of flame-retardant modified zeolite powder, 13-16 parts of expandable graphite, 2-3 parts of paraffin, 1-2 parts of tributyl citrate, 1-2 parts of epoxy tall oil, 2-4 parts of stabilizer and 1-3 parts of anti-aging agent. The flame-retardant and wear-resistant polypropylene pipe is excellent in flame retardance, and good in impact resistance and wear resistance.

Description

technical field [0001] The invention relates to the technical field of polypropylene, in particular to a flame-retardant and wear-resistant polypropylene pipe. Background technique [0002] The basic structure of the polymer chain of random copolymerized polypropylene is modified by adding different types of monomer molecules. Ethylene is the most commonly used monomer, which causes changes in the physical properties of polypropylene. Compared with PP homopolymer, random copolymers have improved optical properties (increased transparency and reduced haze), improved impact resistance, increased flexibility, lower melting temperature, and thus lower heat welding temperature ; At the same time in terms of chemical stability, water vapor barrier properties and organoleptic properties (low odor and taste) are basically the same as homopolymers. It is used in blow molding, injection molding, extrusion molding, film and sheet extrusion processing, and is commonly used in domestic...
