Mixed material for manufacturing high-density polyethylene double-wall corrugated pipe and preparation method thereof

Abstract

The invention provides a mixed material for manufacturing a high-density polyethylene double-wall corrugated pipe and a preparation method thereof, and the mixed material comprises the following components in percentage by weight: 67.99%-53.68% of high-density polyethylene; 2.04%-4.30% of a polyacrylonitrile fiber; 6.80%-10.74% of an ethylene-octene copolymer; 0.21%-0.43% of dicumyl peroxide; 20.40%-26.84% of kaolin; 2.04%-3.23% of maleic anhydride; 0.21%-0.38% of 2-(2-hydroxyl-3-tert-butyl-5-methylphenyl)-5-chlorobenzotriazole, and 0.34%-0.43% of zirconium phosphate loaded with silver. The material configuration optimization and deep processing value-added treatment are carried out according to the physicochemical property requirements and use conditions of the pipe, so that the physicochemical property indexes and long-term stability of the pipe are improved, and the material formula cost is reduced.

Description

technical field [0001] The invention relates to the technical field of bellows materials, in particular to a mixed material for making high-density polyethylene double-wall bellows and a preparation method. Background technique [0002] At this stage, the high-density polyethylene (HDPE) double-wall corrugated pipes produced and processed by domestic pipe companies are all processed by blending and extruding high-density polyethylene (HDPE) and black masterbatch, which makes the product cost high; in order to reduce the cost of materials The formula cost is generally filled with external recycled materials, so that the product quality cannot be guaranteed. It has greatly affected the competitive advantage of the product market and the long-term stability of physical and chemical technical indicators. Contents of the invention [0003] In view of the above situation, the present invention provides a mixed material for making high-density polyethylene (HDPE) double-wall cor...
