Abstract

The invention discloses an environment-friendly modified polyethylene pipeline and a preparation method thereof. The pipeline is prepared from components in parts by weight as follows: high-density polyethylene, low-density polyethylene, nano silicon nitride, modified diatomaceous earth, organic kaolin, nano magnesium sulfate, nano titanium dioxide, wollastonite powder, polyvinyl alcohol, a toughening agent, alkyl sodium sulfonate, hydrogenated castor oil, an acrylnitrile-butadiene-styrene copolymer, a styrene-maleic anhydride copolymer, a silane coupling agent KH570 and masterbatch. A polyethylene pipeline material prepared with the method through proper material selection has excellent mechanical performance, is resistant to impact and ageing and excellent in comprehensive performance and has brighter application prospect.

Description

technical field [0001] The invention relates to the technical field of pipeline materials, in particular to an environmentally friendly modified polyethylene pipeline and a preparation method thereof. Background technique [0002] At present, domestic residential water supply mainly uses pipes such as iron pipes, stainless steel pipes, and plastic pipes. However, iron pipes are easy to rust, which is not conducive to clean water; stainless steel pipes are expensive and not conducive to popularization; plastic pipes are more and more widely used due to their advantages of not being easy to rust and low cost. [0003] Polyethylene pipes have become the second largest consumption of plastic pipes in the world after polyvinyl chloride pipes, and are widely used in water supply, gas transmission, sewage discharge, agricultural irrigation, mine mortar transportation and other fields. However, the polyethylene pipe material itself has shortcomings such as easy aging and degradatio...
