Problems solved by technology

[0003] The main raw material for the production of polyethylene pipes is polyethylene particles. During the polymerization process of polyethylene raw materials, initiators, catalysts, relative molecular mass regulators and terminators will be added. The service life of existing PE pipes is about 10 years. Neither impact resistance nor fastness can meet the needs of ever-increasing application scenarios

Abstract

The invention discloses a high-strength PE pipe and a preparation method thereof. The high-strength PE pipe is prepared from, by mass, 60-85 parts of high-density polyethylene; 1-2 parts of an anti-ultraviolet auxiliary agent; 3-5 parts of a toughening agent; and 1-3 parts of white masterbatch. The high-strength PE pipe is high in impact resistance, high in strength and long in service life.

Description

Technical field: [0001] The invention relates to the field of pipe materials, in particular to a high-strength PE pipe and a preparation method thereof. Background technique: [0002] The existing PE is polyethylene (English abbreviation of Polyethylene of raised temperature resistance), and the PE pipe is a high crystallinity, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and the thin section is translucent to a certain extent. PE has excellent resistance to most domestic and industrial chemicals. [0003] The main raw material for the production of polyethylene pipes is polyethylene particles. During the polymerization process of polyethylene raw materials, initiators, catalysts, relative molecular mass regulators and terminators will be added. The service life of existing PE pipes is about 10 years. Neither the impact resistance nor the fastness can meet the needs of the ever-increasing application scenarios. Invention content: ...
