Abstract

The invention relates to a special material for a high-density high-strength polyethylene optical cable sheath, and the material is prepared from the following main components in parts by weight: 70-80 parts of waste plastic of which the polyethylene purity is more than or equal to 95%, 10-20 parts of refined high-density master batch, 1-9 parts of carbon black master batch, 1-1.5 parts of a compatilizer, 0.5-0.9 part of a lubricant, 0.1-0.6 part of an antioxidant, 6.5-8.5 parts of a filler, 0.9-1.1 parts of an auxiliary antioxidant, 0.9-1.1 parts of a coupling agent, and 0.03-0.04 part of a dispersing agent. The polyethylene optical cable sheath prepared by the preparation method disclosed by the invention has high strength, high wear resistance and high voltage resistance, cracking resistance and aging resistance of an optical cable are ensured, and the polyethylene optical cable sheath can replace imported similar materials and brand-new high-density ethylene optical cable sheath materials.

Description

technical field [0001] The invention relates to environmental protection and resource comprehensive utilization technology, in particular to a high-density polyethylene optical cable sheath material produced by using waste polyethylene plastics. Background technique [0002] my country is in the stage of accelerated development of industrialization, informatization, and urbanization, and the situation of resources and environment is very serious. In order to alleviate the serious problem of less and less earth resources, the country has issued a macro policy to vigorously develop circular economy, requiring the transformation of economic Growth mode, building a resource-saving and environment-friendly society, and comprehensive utilization of resources will be a long-term strategic policy and technical and economic policy in my country's economic and social development. Therefore, resources such as oil and water should be recycled as efficiently as possible to the extent that...
