Outdoor feedwater anti-ageing PE tubular product and preparation method thereof

Abstract

The invention discloses an outdoor feedwater anti-ageing PE tubular product and a preparation method thereof. The outdoor feedwater anti-ageing PE tubular product is prepared from the following raw materials in parts by weight: 55-65 parts of high density polyethylene, 25-35 parts of poly diallyl terephthalate, 15-20 parts of bisphenol A type polyarylate, 4-7 parts of lignite wax, 3-5 parts of ethylene bis stearamide, 6-9 parts of methyl fluoride silicone oil, 2.5-4.5 parts of pentaerythritol monooleate, 10-15 parts of titanium white powder, 10-15 parts of organic montmorillonite, 1-2 parts of dibutyltin dilaurate, 2-4 parts of basic lead carbonate, 1.5-2.5 parts of ethyl-3-amino crotonate, 2-3 parts of diphenylthiourea, 1-2 parts of di(dioctylpyrophosphato) ethylene titanate, 4-8 parts of bis(2-ethylhexyl)phosphate, 18-24 parts of filling master batch, 2-3 parts of bis(2,4-di-tert-butylphenyl)pentaerythritol diphosphite, 1-2 parts of 2,4-di tertbutyl phenol, and 1-2 parts of resorcinol monobenzoate. The PE tubular product, provided by the invention, is good in age resistance and prominent in environmental stress crack resistance and anti-ultraviolet performance, has good heat resistance, flexibility, wear resistance and chemical corrosion resistance, and is long in service life.

Description

technical field [0001] The invention relates to a PE pipe and a preparation method thereof, in particular to an aging-resistant PE pipe for outdoor water supply 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 PE water supply pipes on the market have poor aging resistance and are prone to cracking when exposed outdoors. , which greatly reduces the service life of the PE pipe and limits its application range. Therefore, there is an urgent need to develop an aging-...
