High-strength PE pipe and production method thereof

Abstract

The invention discloses a high-strength PE pipe. The high-strength PE pipe sequentially comprises a PE layer, a resin layer, an inner glass fiber layer, a quartz sand layer and an outer glass fiber layer from inside to outside, wherein the PE layer comprises the following components in parts by weight: 20-30 parts of polyethylene, 10-15 parts of an ethylene-propylene methylene copolymer, 10-12 parts of polypropylene fiber, 8-10 parts of diatomite, 3-5 parts of quartz sand, 2-3 parts of glass reinforced plastic and 2-3 parts of activated carbon. Through addition of the quartz sand, the glass reinforced plastic, the activated carbon and other raw materials in the high-strength PE pipe, the finally produced high-strength PE pipe is relatively high in strength; in addition, the quartz sand hasrelatively strong corrosion resistance and wear resistance, the produced high-strength PE pipe has good corrosion resistance and wear resistance, is unlikely to damage and is long in service life.

Description

technical field [0001] The invention belongs to the technical field of high-strength PE pipe processing, and in particular relates to a high-strength PE pipe and a processing method thereof. Background technique [0002] Cable conduit is a protective pipe commonly used in cable laying in various places in recent years. Plastic pipes such as MPP and PE are often used, which have poor strength, cannot bear heavy pressure, are flammable and fragile, are not heat-resistant, are not aging-resistant, and have a short life. . In order to enhance the strength of the pipe, when the existing pipe is processed, a layer of glass fiber is wound outside the pipe. Although the strength of the pipe can be enhanced to a certain extent, the strength of the pipe is still difficult to meet the high-intensity operation requirements, and the service life is short. . Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a high-strengt...

[0002] Cable conduit is a protective pipe commonly used in cable laying in various places in recent years. Plastic pipes such as MPP and PE are often used, which have poor strength, cannot bear heavy pressure, are flammable and fragile, are not heat-resistant, are not aging-resistant, and have a short life.

In order to enhance the strength of the pipe, when the existing pipe is processed, a layer of glass fiber is wound outside the pipe. Although the strength of the pipe can be enhanced to a certain extent, the strength of the pipe is still difficult to meet the high-intensity operation requirements, and the service life is short.
