Problems solved by technology

[0002] It is used to manufacture high-impact cable special materials. The main raw materials are low-density polyethylene, medium-density polyethylene, polyvinyl chloride (PVC), polyethylene (PE) and other polyolefin resins. The cable special materials prepared from the above materials have a price It is very high and produces a lot of waste at the lower corners, which causes headaches for downstream customers in raw material procurement and process use. They need a solution that can not only reduce production costs, but also solve the increasing pressure on environmental protection.

Abstract

A special material used for cables with high shock resistance and prepared from recovered waste polyethylene and a preparing method thereof are disclosed. The special material includes 50-75 parts of a recovered cable material as a base, and 5-10 parts of chlorinated polyethylene, 5-10 parts of an ACR shock-resistant modifier, 5-10 parts of coloring carbon black, 10-30 parts of anhydrous calcium sulfate having a size of 400 meshes and 2-5 parts of an auxiliary agent are added. The special material is prepared through steps of extrusion, wire drawing, water cooling and granulation. The special material has a plurality of excellent comprehensive economic and technical performance indexes, such as excellent thermoplastic elastomer performance, waterproofness, seepage resistance, good weatherability, high tensile strength, high shock resistance, a high elongation percentage, a high friction coefficient, high deformation adaptability, a wide temperature adaptation range, using convenience, long service lifetime, easy construction and a low cost. Considerable economic benefit and social benefit can be generated. More importantly, waste is turned into things of value, energy is saved, and the special material and the method are low in carbon and environment friendly.

Description

technical field [0001] The invention belongs to the field of recycling and utilization of waste materials, and relates to a special material for high-impact cables prepared from recycled waste polyethylene and a preparation method thereof. Background technique [0002] It is used to manufacture high-impact cable special materials. The main raw materials are low-density polyethylene, medium-density polyethylene, polyvinyl chloride (PVC), polyethylene (PE) and other polyolefin resins. The cable special materials prepared from the above materials have a price It is very high and produces a lot of waste at the lower corners, which causes headaches for downstream customers in raw material procurement and process use. They need a solution that can not only reduce production costs, but also solve the increasing pressure on environmental protection. Based on the above practical problems such as production and market, it is particularly urgent to find a process that can recycle waste...
