Abstract

The invention relates to a regenerated PE jacket material and a preparation method and application thereof and belongs to the field of cable production and manufacturing technology and regenerated resource recycling. The regenerated PE jacket material comprises, by weight, 5 to 15 parts of high-density polyethylene injection molding material, 5 to 15 parts of high-density polyethylene hollow material, 10 to 20 parts of large white film material, 20 to 40 parts of secondary white film material, 5 to 15 parts of heat transfer film material, 3 to 8 parts of rat and ant resisting master batch, and5 to 8 parts of processing aid. The regenerated PE jacket material adopts the waste polyethylene in life, agricultural films, industrial films and the like as raw materials, so that the raw materialsare wide in source, and the economical benefit is significant; the mechanical performance of the regenerated PE jacket material of the invention can reach the industrial standard, and has the advantages of long-acting rat and ant resistance, smooth appearance of a formed cable, weather resistance, and environment stress cracking resistance; and the preparation method is simple in process, high inefficiency and high in industrialized production efficiency.

Description

technical field [0001] The invention relates to a recycled PE sheath material and its preparation method and application, and belongs to the fields of cable manufacturing technology and recycling of renewable resources. Background technique [0002] With the country's scientific and technological progress and rapid economic development, electric power, communications, transportation and other industries are developing rapidly, and the laying and use of optical cables or cables are limited by the environment, requiring outer protective layers with different functions to protect them, such as long-term anti-rodent ants , weather resistance, anti-cracking and other functions. The recycled PE sheath material has been recognized by the market for its excellent cost performance, and is widely used in the cable and optical cable industry, making great contributions to reducing industry costs and resource recycling. [0003] As one of the four major thermoplastic general-purpose ma...
