Anti-aging PE water supply pipe

Abstract

The invention discloses an anti-aging PE water supply pipe, and particularly relates to the field of pipes, the anti-aging PE water supply pipe comprises the following raw materials by weight: 90-100 parts of low density polyethylene, 6-8 parts of bentonite, 0.1-0.3 part of tribasic lead sulfate, 2-4 parts of stearamide, 2-4 parts of sodium polyacrylate, 0.1-0.3 part of isopropyl dioleoyl (dioctyl phosphate) titanate, 0.1-0.3 part ofN-isopropyl-N'-phenyl p-phenylenediamine 0.1-0.3 part of 2-mercaptobenzimidazole, 1-3 parts of glycerol triacetate, 10-15 parts of filler and 3-5 parts of a modifying aid, the filler is one selected from glass fiber, diatomite, asbestos and carbon black, and the modifying aid is one selected from a silane coupling agent, a titanate coupling agent or an aluminate coupling agent. According to the PE water supply pipe, the ageing resistance of the PE water supply pipe can be effectively improved, meanwhile, the mechanical property of the PE water supply pipe is improved through the wear-resistant material in the filler, and therefore the service life of the PE water supply pipe can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of pipe materials, and more specifically, the invention relates to an anti-aging PE water supply pipe. Background technique [0002] Pipes are necessary materials for construction projects. Commonly used are water supply pipes, drainage pipes, gas pipes, heating pipes, wire conduits, rainwater pipes, etc. Among them, PE water pipe is also an important water supply pipe material. PE material is widely used in the field of water supply pipe manufacturing due to its high strength, high temperature resistance, corrosion resistance, and non-toxicity. Because it will not rust, it is an ideal pipe material to replace ordinary iron water supply pipes; metallocene linear low-density polyethylene is a non-inert material, except for a small amount of strong oxidants, it is resistant to corrosion by various chemicals, and it is not easy to breed bacteria. As we all know, the reason why steel pipes and cast iron pipes a...

Problems solved by technology

[0003] However, in actual use, as the external environment is getting worse and worse, the environment in which PE water supply pipes are used is getting worse and worse, which also leads to the performance of PE water supply pipes becoming increasingly unable to meet the harsh environment. It is easy to oxidize with the outside air during use, which leads to more and more obvious aging of PE water supply pipes.
