A cable sheath material with high impact strength and flex resistance

Abstract

The invention discloses a high-shock-strength bending-resistant cable sheath material. The cable sheath material comprises raw materials in parts by weight as follows: 7-9 parts of an SBS (styrene-butadiene-styrene block copolymer), 20-22 parts of an EVA (ethylene-vinyl acetate copolymer), 25-30 parts of MA (methyl acrylate), 5-6 parts of quartz fibers, 1-3 parts of carbon-silicon fiber, 3-4 parts of polyacrylonitrile fibers, 4-6 parts of calcite, 7-9 parts of wollastonite, 5-8 parts of barite powder, 2-4 parts of hollow glass microspheres, 1-3 parts of decabromodiphenyl ether, 4-6 parts of antimony trioxide, 3-6 parts of microcrystalline wax, 4-6 parts of butyl stearate, 0.1-0.3 part of SBS-g-MA, 0.1-0.3 part of EVA-g-MA and 0.5-0.9 part of an anti-aging agent RD. The cable sheath material is excellent in shock strength and bending resistance, good in flame retardation, low in density and beneficial to erection of cables.

Description

technical field [0001] The invention relates to the technical field of cable sheath materials, in particular to a cable sheath material with high impact strength and flex resistance. Background technique [0002] With the development of the economy, the demand market for cables is broad, which promotes the progress of the production technology of cable materials. Cable materials are not only widely used, but also have special requirements for their performance indicators, such as insulation, impact strength, service temperature, and flame retardancy. There are strict requirements on performance and other indicators. Continuously improving the performance of cable materials is an urgent need for economic and social development. Traditional cable materials often have problems such as poor flame retardancy, bending and easy fracture, poor mechanical properties, and short service life. , brings a lot of inconvenience to the actual use, and even threatens the safety of people's l...

Problems solved by technology

[0002] With the development of the economy, the demand market for cables is broad, which promotes the progress of the production technology of cable materials. Cable materials are not only widely used, but also have special requirements for their performance indicators, such as insulation, impact strength, service temperature, and flame retardancy. There are strict requirements on performance and other indicators. Continuously improving the performance of cable materials is an urgent need for economic and social development. Traditional cable materials often have problems such as poor flame retardancy, bending and easy fracture, poor mechanical properties, and short service life. , brings a lot of inconvenience to the actual use, and even threatens the safety of people's lives and properties. Therefore, it is urgent to change the original cable material formula and improve the material performance to meet the diverse needs of the cable market.
