Weather-proof and ozone-proof modified polyethylene cable sheath material

Abstract

The invention relates to a cable material, and specifically relates to a weather-proof and ozone-proof modified polyethylene cable sheath material. The material comprises the following raw materials in parts by weight: 40-45 parts of linear low density polyethylene, 14-18 parts of EVA (Ethylene-Vinyl Acetate) resin, 2-3 parts of a silane coupling agent KH-550, 8-10 parts of acrylamide, 2-3 parts of polyvinyl alcohol, 1-2 parts of an accelerant DM, 3-5 parts of zinc oxide, 1-2 parts of phenyltriethoxysilane, 1-2 parts of an accelerant DM, 25-29 parts of carbon black, 1.0-2.0 parts of an accelerant M, 18-22 parts of tributyl citrate, 14-18 parts of bentonite powder and 14-16 parts of an assistant. The insulating material combines the advantages of the raw materials such as linear low density polyethylene and EVA resin, and the prepared material is flexible and wear-resistant, environmental climate aging-resistant, ozone corrosion-resistant, good in chemical stability, dampproof and waterproof and safe and reliable to use, can be widely applied to preparation of various cable sheath insulating materials, and is promising in market requirement.

Description

technical field [0001] The invention relates to a cable material, in particular to a weather-resistant and ozone-resistant modified 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 s...

[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.
