Abstract

The invention relates to a cable material, and in particular relates to a flexible oil-proof modified polyvinyl chloride (PVC) cable sheath material. The material is prepared from the following raw materials in parts by weight: 32-35 parts of SG-4PVC, 14-18 parts of EVA (ethylene-vinyl acetate), 14-16 parts of metallocene linear low-density polyethylene, 3-4 parts of beryllium oxide, 11-15 parts of silicon carbide, 4-6 parts of attapulgite, 1-2 parts of accelerator Na-22, 16-19 parts of epoxy linseed oil, 24-28 parts of N660 carbon black, 3-4 parts of zinc oxide, 3-4 parts of stearic acid, 1-2 parts of anti-aging agent 4010, 3-4 parts of asbestos powder, 17-21 parts of tributyl citrate, and 14-16 parts of additive; the advantages of the raw materials such as SG-4PVC, the EVA and the metallocene linear low-density polyethylene are combined through the insulating material, the prepared material is firm and flexible, oil permeation resistant, low temperature embrittling resistant, chemical medicine erosion resistant, and safe and reliable in use, and can be widely used for manufacturing various cable sheath insulating materials, and the market demand prospect is wide.

Description

technical field [0001] The invention relates to a cable material, in particular to a flexible oil-resistant modified polyvinyl chloride cable sheath material and a preparation method thereof. Background technique [0002] With the development of the economy, the places where cables need to be used have become diversified, and there are more stringent and diverse requirements for the performance indicators of cable sheath materials, such as insulation, tensile strength, service temperature, flame retardant performance and other indicators There are strict requirements, and continuous improvement of the performance of sheath materials is an urgent need for economic and social development. Traditional sheath materials often have poor flame retardancy, poor chemical stability, high temperature deformation, poor mechanical properties, and short service life. And other problems, bring a lot of inconvenience to the actual use, and even threaten people's life and property safety, th...
