Mould-prevention polyethylene water supply tubular product and preparation method thereof

Abstract

The invention discloses a mould-prevention polyethylene water supply tubular product and a preparation method thereof. The mould-prevention polyethylene water supply tubular product is prepared from the following raw materials in parts by weight: 50-70 parts of medium density polyethylene, 25-45 parts of metallocene linear low density polyethylene, 20-30 parts of nylon 12, 15-20 parts of dimethyl fumarate, 4-8 parts of perfluorinated polyether lubricating grease, 3-6 parts of liquid paraffin, 1-2 parts of protocatechuic acid ethyl ester, 2-3 parts of propylparaben, 1.5-2.5 parts of trichlamide, 2.5-4.5 parts of antimony sulfate, 5-10 parts of jade powder, 15-20 parts of calcining loess, 2-3 parts of dodecanoic acid monoester with triglycerol, 1-2 parts of zinc undecylenate, 5-10 parts of epoxidized soybean oil, 1-2 parts of calcium stearate, 1-2 parts of barium stearate, 20-25 parts of filling master batch, 10-15 parts of dicyclohexyl phthalate, 2-3 parts of N,N'-Bis(1-methylpropyl)-1,4-phenylenediamine and 1.5-2.5 parts of chlorotributyltin. The mould-prevention polyethylene water supply tubular product has excellent antibacterial property, can effectively restrain and prevent attachment and breeding of mould, prevents mould from corroding the tubular product, has excellent mechanical property, ageing resistance, heat resistance and processability, and is long in service life and wide in application prospect.

Description

technical field [0001] The invention relates to a PE pipe material and a preparation method thereof, in particular to a mildew-proof polyethylene 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. Currently, PE water supply pipes on the market are easily damaged by mold erosion in humid environments. The service life of the PE pipe is greatly reduced and its application range is limited. Therefore, be badly in need of developing a kind of mold-resistant ...
