A kind of anti-corrosion and wear-resistant polyethylene pipe

Abstract

The invention relates to an anti-corrosion abrasion-proof polyethylene pipe which comprises a pipe body and an anti-corrosion abrasion-proof layer, wherein the anti-corrosion abrasion-proof layer comprises the following components in parts by weight: 80-120 parts of epoxy resin, 80-120 parts of polyurethane, 30-60 parts of coal pitch, 18-32 parts of a curing agent, 22-45 parts of a rust inhibitor, 6-26 parts of a lubricant, 30-180 parts of a mineral oil, 1.5-8 parts of aluminium sesquioxide, 5-12 parts of copper dioxide, 8-15 parts of dimethyl benzene, and 3-10 parts of normal butyl acetate. The polyethylene pipe has low probability of scratching during the using process, and prolongs the service life.

Description

technical field [0001] The invention relates to a pipe material, in particular to an anti-corrosion and wear-resistant polyethylene pipe. Background technique [0002] The laying link often plays an important role in the cost and energy consumption of plastic pipeline projects. The basis of trenchless laying technology is to lay the pipeline to the required underground line position by using the trenchless method. The most widely used trenchless technology for laying concrete pipes and steel pipes is the pipe jacking method. In the laying of plastic pipes The most widely used non-excavation technology is the horizontal directional drilling method, because the non-excavation laying needs to pull or push the plastic pipe into the hole drilled at the bottom or into the old pipe to be repaired. During this process, the surface of the pipe will inevitably be damaged. It is very likely that direct contact with sharp stones will form a concentrated load in the pipe wall, thereby d...

In the laying of plastic pipes The most widely used non-excavation technology is the horizontal directional drilling method, because the non-excavation laying needs to pull or push the plastic pipe into the hole drilled at the bottom or into the old pipe to be repaired. During this process, the surface of the pipe will inevitably be damaged. It is very likely that direct contact with sharp stones will form a concentrated load in the pipe wall, thereby damaging the high stress concentration and causing potential use risks. However, the wear resistance of ordinary polyethylene pipe coatings is not high, and the surface is easily worn
