Abstract

The invention discloses an HDPE double-layer steel belt hot melting sewage pipe material containing ardealite and a preparation method thereof. The HDPE double-layer steel belt hot melting sewage pipematerial is prepared from the following components in parts by weight: 120-160 parts of high-density polyethylene, 140-160 parts of ardealite, 4-6 parts of color master batch, 9-12 parts of a defoaming agent, 0.5-1.5 parts of stearic acid, 5-8 parts of artemisia apiacea powder, 1-3 parts of methyl cellulose and 0.5-1.5 parts of epoxy resin. The materials are mixed and then subjected to extrusionmolding, shaping and cooling, cutting and packaging to obtain a finished product. The pipe produced by replacing calcium powder with ardealite has excellent physical and mechanical properties and chemical properties, calcium sulfate is absorbed by utilizing artemisia apiacea powder, the toxicity of ardealite is reduced, the HDPE double-layer steel belt hot melting sewage pipe material is suitablefor sewage discharge, the application rate of ardealite is increased, the environmental problem caused by large-scale stockpiling of ardealite is solved, and economic benefits are created.

Description

technical field [0001] The invention belongs to the field of PE pipe production, and in particular relates to a HDPE double-layer steel strip hot-melt sewage pipe material containing phosphogypsum and a preparation method. Background technique [0002] High-density polyethylene (HDPE) has high temperature resistance, oil resistance, steam permeability resistance and environmental stress crack resistance, good chemical stability, and can withstand most acid and alkali corrosion. In addition, electrical insulation and impact resistance and Good cold resistance, mainly used in blow molding, injection molding and other fields. Polyethylene has a long history of being used to produce pipes, and is widely used in many fields such as water supply, gas transmission, agricultural irrigation, oilfield chemical industry and communication. [0003] The production of polyethylene pipes in the prior art generally uses polyethylene as the main material, PE recycled material as the filler,...
