Abstract

A special high-transparency and high-impact-resistance cable material prepared from recycled waste polyethylene is prepared from 50-75 parts of recycled cable materials serving as a base stock, 5-10 parts of an MBS impact modifier, 5-10 parts of an ACR impact modifier, 5-10 parts of coloring carbon titanium dioxide, 10-30 parts of 400-mesh anhydrous calcium sulfate and 2-5 parts of an auxiliary. The special modified cable material is prepared with a method including steps of extrusion, drawing, water cooling and granulation. The special modified cable material prepared from the recycled waste polyethylene has multiple excellent comprehensive economic and technical performance indexes such as excellent thermoplastic elastomer performance, water-proof performance, leaking resistance, weather resistance, high tensile strength, high impact resistance, high elongation, large friction coefficient, high deformation adaptability, wide temperature adaptation range, convenience in use, long service life, easiness in construction, low manufacturing price and the like and can create considerable economic and social benefits, more importantly, waste can be turned into wealth, and the cable material is energy-saving, low-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-transparency and high-impact cables prepared from recycled waste polyethylene and a preparation method thereof. Background technique [0002] It is used to manufacture special materials for high-transparency and high-impact cables. The main raw materials are low-density polyethylene, medium-density polyethylene, polyvinyl chloride (PVC), polyethylene (PE) and other polyolefin resins. The special materials for cables prepared from the above materials , the price is very high, and a lot of corner waste is produced, which causes downstream customers to have a headache in raw material procurement and process use. They need a method that can not only reduce production costs, but also solve the growing pressure on environmental protection. Based on the above practical problems such as production and market, it is particularly urgent ...
