Abstract

The invention relates to a special material for modification and regeneration of a polyethylene anticorrosive pipeline and a preparation method thereof, belonging to the technical field of waste polyethylene recycling. The special material for modification and regeneration is prepared from the raw materials of polyethylene, recycled polyethylene, a toughening agent, glass beads, carbon black, an antioxidant 300, a secondary antioxidant DLTP, an ultraviolet absorbent UV-531 and white mineral oil by working procedures such as mixing and extruding. The special material effectively reduces the production cost of the polyethylene anticorrosive pipeline, solves the problems that the increasing amount of existing polyethylene waste causes pollution to the environment, and forms great waste of resources, and has positive significance for saving the resources, reducing the production cost, protecting the environment and the like.

Description

technical field [0001] The invention relates to a polyethylene anti-corrosion pipeline modified and recycled special material and a preparation method thereof, belonging to the technical field of waste polyethylene recycling. Background technique [0002] High-density polyethylene has good heat resistance and cold resistance, good chemical stability, high rigidity and toughness, good mechanical strength, good dielectric properties, and good environmental stress cracking resistance. It can be widely used in the preparation of packaging films, ropes, woven nets, fishing nets, water pipes, plastic boxes, turnover boxes, extrusion blow molding containers, hollow products and bottles, etc. Due to its wide use, polyethylene waste is increasing day by day, which not only pollutes the environment, but also causes a great waste of resources. Among the polyethylene anti-corrosion pipelines, the polyethylene with the largest consumption and the highest cost accounts for about 70% of t...
