Impact resistance modified polyolefin cable sheath material

Abstract

The invention relates to a cable material, and concretely relates to an impact resistance modified polyolefin cable sheath material, and the material contains the following raw materials by weight: 30-34 parts of ethane-vinyl acetate, 14-17 parts of metallocene linear low density polyethylene, 9-12 parts of poly 1-butylene, 12-15 parts of aluminium hydroxide, 5-7 parts of TPE elastomer, 2-3 parts of zinc stearate, 5-7 parts of melamine resin, 2-3 parts of vinyltriethoxysilane, 1-2 parts of promoter PZ1, 20-25 parts of nanometer silica, 1-2 parts of aluminate coupling agent DL-411, 2-3 parts of methyl diphenylene diisocyanate, 24-30 parts of tributyl citrate, 6-8 parts of alumina and 14-16 parts of auxiliary agent; the insulating material combines advantages of ethane-vinyl acetate copolymer, metallocene linear low density polyethylene and other raw materials, and the prepared material has the advantages of sturdiness and flexibility, anti-impact, ozone age resistance, aging resistance, chemical stability resistance, and can be widely used for making various cable sheath insulating materials with wide market demand prospect.

Description

technical field [0001] The invention relates to a cable material, in particular to an impact-resistant modified polyolefin 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, therefore, it i...

[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.
