Damp-proof flexible modified chlorinated polyethylene cable sheath material

Abstract

The invention relates to a cable material, and particularly relates to a damp-proof flexible modified chlorinated polyethylene cable sheath material. The material comprises the following active ingredients in parts by weight: 23-24 parts of chlorinated polyethylene, 12-14 parts of low-density polyethylene, 14-17 parts of EVA (ethylene / vinyl acetate), 13-14 parts of adipic acid dioctyl ester, 12-13 parts of dioctyl sebacate, 8-10 parts of medical stone powder, 12-14 parts of vermiculite powder, 12-15 parts of aluminum silicate, 10-15 parts of white carbon black, 3-4 parts of hydrogenated cardanol, 1-2 parts of catechol, 4-6 parts of zinc oxide, 2.5-3.5 parts of zinc stearate, 1-2 parts of molybdenum disulfide, and 14-16 parts of auxiliaries. An insulating material combines the advantages of chlorinated polyethylene, low-density polyethylene, EVA and other raw materials, the prepared material is light in weight and flexible, waterproof and damp-proof, tear-proof, chemical reagent-resistant, oil-proof and flame-retardant, can be widely used for producing various cable sheath insulating materials, thus having wide market demand prospects.

Description

technical field [0001] The invention relates to a cable material, in particular to a moisture-proof flexible modified chlorinated polyethylene 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 saf...

[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 the safety of people's lives and property. Therefore, it is urgent to change the original sheath material formula and improve the material performance to meet the diverse needs of the cable market.
