Modified flexible ozone-resistant polyethylene cable sheath material

Abstract

The invention relates to a cable material, and in particular relates to a modified flexible ozone-resistant polyethylene cable sheath material. The cable sheath material is prepared from the following raw materials in parts by weight: 28 to 32 parts of low-density polyethylene, 18 to 23 parts of ethylene-vinyl acetate copolymer (EVA), 3 to 5 parts of ACR (Acrylate) impact modifier, 2 to 3 parts of tungsten boride, 4 to 6 parts of aluminum nitride, 1 to 2 parts of ricinoleic acid, 12 to 15 parts of talcum powder, 8 to 12 parts of bentonite powder, 15 to 17 parts of diisononyl phthalate, 15 to 18 parts of propanediol sebacate polyester, 10 to 12 parts of sodium fluosilicate, 4 to 6 parts of barium sulfate, 1 to 2 parts of phenol and 14 to 16 parts of auxiliary agent. The prepared cable sheath material is firm and flexible, and has the performance of aging resistance, ozone resistance, tearing resistance and chemical solvent resistance by combining the advantages of the low-density polyethylene, the ethylene-vinyl acetate copolymer (EVA) and the other raw materials. Thus, the prepared cable sheath material is safe and reliable to use. Therefore, the cable sheath material can be widely used for preparing various cable sheath insulating materials. The cable sheath material provided by the invention has broad market demand prospect.

Description

technical field [0001] The invention relates to a cable material, in particular to an ozone-resistant flexible 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 safety, there...

[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.
