Corrosion resistant PE water pipe

Abstract

The invention discloses a corrosion resistant PE water pipe. The raw materials of the pipe include, be weight percentage: 94% to 98% of HDPE (high-density polyethylene), 0.2% to 0.8% of masterbatch, 0.1% to 0.6% of phthalic acid ester, 0.3% to 0.5% of (BHT) 2,6-butylated hydroxytoluene, 0.4% to 0.7% of methyl thiopropionate, 0.2% to 0.6% of azobisformamide, 0.2% to 0.5% of di-n-octyltin moleate, 0.4% to 1.2% of tetrakis (beta-(3,5-di-t-butyl-4-hydroxyphenyl) propionate) pentaerythritol ester, 0.4% to 1.1% of EVA and 1% to 5% of clay nanocomposite. The pipe has fine chemical corrosion resistance, particularly in the complex chemical corrosion environments of acid, alkali and oil, corrosion of various chemical medias can be resisted, and the pipe is prevented from rotting and corrosion, is durable and has the practical value.

Description

technical field [0001] The invention relates to the field of pipe materials, in particular to a corrosion-resistant PE water supply pipe. Background technique [0002] PE water supply pipes are widely used in building water supply, building drainage, buried drainage pipes, etc. PE water supply pipe has the following advantages: 1. Good transportation performance, low energy consumption for water delivery, low energy consumption for living, light weight, small water flow resistance, easy and fast installation, low cost, long life, and heat preservation function, etc.; 2. It has unique flexibility and excellent scratch resistance. The good flexibility enables the PE water supply pipe to be coiled and supplied in a longer length, avoiding a large number of joints and pipe fittings; 3. It has good fast Crack growth fracture toughness can reduce pipeline leakage accidents due to rapid crack growth and fracture of pipelines. In recent years, with the continuous development of sc...

AI Technical Summary

Problems solved by technology

In recent years, with the continuous development of science and technology, people have higher and higher performance requirements for PE water supply pipes. Although the PE water supply pipes currently on the market have certain corrosion resistance, their corrosion resistance is poor, especially in In the case of acid, alkali, oil and other corrosive media, PE water supply pipes are more likely to corrode, which greatly reduces the service life of PE water supply pipes. People need to replace water supply pipes frequently, resulting in a waste of resources. At the same time, manufacturers need to produce more PE water supply pipe, which is bound to aggravate the pollution of the environment

At present, there is no PE water supply pipe with strong corrosion resistance in my country.
