Abstract

The invention provides a glass fiber reinforced polyethylene water feed pipe. The glass fiber reinforced polyethylene water feed pipe comprises a pipe body. The pipe body is formed by combining an inner layer, a core layer and an outer layer. The inner layer and the outer layer are both made of HDPE materials. The material of the core layer is a pretreated glass fiber tape winding layer. An inner transition connecting layer is arranged between the inner layer and the core layer, and an outer transition connecting layer is arranged between the outer layer and the inner layer. The glass fiber reinforced HDPE is adopted, and due to the fact that the elasticity modulus of glass fiber is 60 MPa and is far larger than that of HDPE with the elasticity modulus being 0.8 MPa, glass fiber cloth is adopted as the inner layer, grafting is achieved through an inner and outer transition connecting layer coupling agent, and accordingly the anti-pressure ability of the HDPE water feed pipe can be achieved.

Description

technical field [0001] The invention relates to the field of building material production, in particular to a glass fiber reinforced polyethylene water supply pipe. Background technique [0002] PE (polyethylene) material is widely used in the field of water supply pipe manufacturing due to its high strength, corrosion resistance, and non-toxicity. Because it will not rust, it is an ideal pipe to replace ordinary iron water supply pipes. PE water supply pipe implements the national product standard: GB / T 13663-2000 "polyethylene (PE) pipes for water supply". my country's plastic pipes are developing rapidly and their quality is constantly improving. Among them, polyethylene PE pipes are widely used in building water supply, building drainage, buried drainage pipes, building heating, gas pipelines, electrical and telecommunications protection casings, industrial pipes, agricultural pipes, etc. due to their unique advantages. It is mainly used in urban water supply, urban ga...
