Anti-corrosion PE water supply pipe and preparation method thereof

Abstract

The invention discloses an anti-corrosion PE water supply pipe and a preparation method thereof. The pipe is prepared from the following raw materials by weight part: 46-62 of ultra-high molecular weight polyethylene, 22-36 of polyphenylene sulfide, 12-24 of a liquid crystal polymer, 10-15 of terpene resin, 16-22 of precipitated barium sulphate, 10-15 of magnesia, 8-14 of nano-calcium titanate, 2-3 of dibasic lead phthalate, 1.5-2.5 of zinc ricinate, 1-2 of barium ricinate, 2-3 of trimethylolpropane, 1-2 of thiodiethylene glycol bis(beta-aminocrotonic acid)ester, 1.5-2.5 of stearoylbenzoylmethane, 2-4 of docosanamide, 3-5 of glycerol triacetylricinoleate, 4-8 of solid paraffin, 22-28 of filling masterbatch, 10-15 of liquid nitrile rubber, 1-2 of 1, 4-cyclohexanedimethanol dibenzoate, and 1-2 of N, N'-bis[beta-(3, 5-di-tert-butyl-4-hydroxyphenyl)propionyl]hydrazine. The PE pipe provided by the invention has excellent resistance to chemical corrosion, can resist erosion of a variety of chemical mediums, especially acid, alkali, salt and oil, and is free of electrochemical corrosion, has strong adaptability to the environment, does not rot or corrode after long-term use, and is durable in use.

Description

technical field [0001] The invention relates to a PE pipe material and a preparation method thereof, in particular to a corrosion-resistant PE water supply pipe material and a preparation method thereof. Background technique [0002] PE pipes are widely used in the field of water supply manufacturing because of their high strength, high temperature resistance, corrosion resistance, non-toxicity, and wear resistance. They are replacement products for traditional steel pipes and PVC drinking water pipes. In recent years, with the rapid development of science and technology and the continuous improvement of people's living standards, the performance requirements of PE water supply pipes are getting higher and higher. At present, the corrosion resistance of PE water supply pipes on the market is poor. Under such corrosive media, raw rot and electrochemical corrosion are prone to occur, which greatly reduces the service life of PE pipes and limits its application range. Therefor...

In recent years, with the rapid development of science and technology and the continuous improvement of people's living standards, the performance requirements of PE water supply pipes are getting higher and higher. At present, the corrosion resistance of PE water supply pipes on the market is poor. Under corrosive media such as raw rot and electrochemical corrosion, it is easy to occur, which greatly reduces the service life of PE pipes and limits its application range.
