Abstract

The invention discloses a three-layer composite liquid crystal polymer enhanced pipe. The composite liquid crystal polymer enhanced pipe is characterized by sequentially and coaxially covering an outer functional material layer, an intermediate thermotropic liquid crystal polymer engineering plastic enhanced layer and an inner functional material layer; the intermediate thermotropic liquid crystal polymer engineering plastic enhanced layer forms a spiral directional array in an equal distance on the outer edge of the inner layer of a pipe along a flowing direction. According to the composite liquid crystal polymer pipe, liquid crystal winding molding is carried out by using a special device and utilizing the strength and the pressure resistance property of the liquid crystal, as well as the high intensity and high flexibility and self-fusion property of polyethylene, so that the use of inner layer materials and outer layer materials under special work conditions such as abrasion resistance, corrosion resistance, flame retardant, anti-static electricity and super-lubrication can be realized, the heatproof property and pressure resistance levels of the pipeline can be improved based on the property of the liquid crystal polymer, and the water delivery requirement of the pressure of 20 MPa can be realized at maximum.

Description

technical field [0001] The invention belongs to the field of polyethylene pipes, and is a three-layer composite liquid crystal polymer reinforced pipe with high pressure bearing, high wear resistance, oxygen resistance, high temperature resistance, high impact resistance, antistatic and flame resistance. Background technique [0002] At present, polyethylene pipes have become the second largest consumption of plastic pipes in the world after PVC, and are widely used in water supply, agricultural irrigation, gas transmission, sewage discharge, floor heating, mine mortar transportation and other projects as well as oil fields, chemicals and post and telecommunications and other fields. With the advancement of technology, the performance requirements for polyethylene pipes are increasing in many occasions. For example, chemical pipelines have gradually increased requirements for anti-corrosion performance, and the requirements for pipeline pressure have gradually increased; Th...
