Abstract

The invention belongs to novel polymer composite materials and relates to a PPR pipe material and a manufacturing method thereof. The material is composed of the following components in parts by weight: 60-84 parts of polypropylene random copolymer, 6-40 parts of flame retardant, 0.75-1.5 parts of antistatic agent and 0.3-0.6 part of antioxidant. The flame retardant is added to improve the flame retardant property of the PPR pipe material, the antistatic agent is added to improve the antistatic property of the PPR pipe material, and the flame-retardant and antistatic PPR pipe material provided by the invention is simple in preparation process and easy to process.

Description

technical field [0001] The invention belongs to novel polymer composite materials, and relates to a PPR pipe material and a manufacturing method thereof. Background technique [0002] PPR pipe is also called three-type polypropylene pipe and random copolymerized polypropylene pipe. It is made of special materials for random copolymerized polypropylene pipes through extrusion. In addition to the advantages of general plastic pipes such as light weight, good strength, corrosion resistance and long service life, PPR pipes also have other advantages: smooth inner wall, low flow resistance and no scaling; simple and convenient installation and operation, weldability, and It is welded together in a few seconds; the waste products generated in the production and construction of PPR pipes can be recycled, which can reduce production costs and do not pollute the environment. [0003] PPR pipe is a non-flame retardant material, which is easy to burn in case of fire. PPR tubes are no...
