Abstract

The invention belongs to reinforced ultra-high molecular weight polyethylene winding pipe and its preparation method. One or more layers of ultra-high molecular weight polyethylene profiles are used as winding materials, arranged in regular, mirror image or phase dislocation, and melted between adjacent side walls / periphery Interconnected or adjacent side walls / peripherals are fusion-bonded with frit material applied, and spirally wound to form the pipe wall; the wound material is stretched to orient the molecules along the longitudinal direction of the profile; reinforcement is applied to the UHMWPE base material materials and / or wear-resistant materials and / or flame-retardant materials and / or antistatic materials; welding materials are plastic polymers, or are reinforced and / or wear-resistant and / or flame-retardant and / or antistatic materials are applied to form plastic Melted co-extrusion; the distribution of reinforcing materials in the winding material and / or welding material is oriented in the helical direction along the axis of the high-strength winding pipe. It has higher impact resistance, yield strength, wear resistance, flame retardancy and antistatic ability, and can produce large-diameter pipes with small equipment.

Description

technical field

[0001] The invention belongs to the field of engineering components, and in particular relates to a reinforced ultra-high molecular weight polyethylene winding pipe and a preparation method thereof. Widely used in mines, steel plants, thermal power plants, chemical plants, oil fields, various acid liquids, lye, crude oil, refined oil, tailings slurry, coal water slurry, power plant ash discharge, slag discharge and other pipeline applications. Background technique

[0002] Due to a series of superior properties such as light weight, corrosion resistance, small flow resistance, convenient construction, and long service life, plastic pipes are gradually replacing traditional pipes such as cast iron pipes, cement pipes, and ceramic pipes, and are increasingly widely used in the field of water supply and drainage.

[0003] In the existing technology, the molecular arrangement of the plastic pipe is oriented along the axial direction of the pipe during the extrusi...
