Abstract

The invention discloses a high-strength and anti-impacting natural rubber cable sheathing material. The high-strength and anti-impacting natural rubber cable sheathing material is prepared from the following raw materials: natural rubber, polyvinyl chloride, low-density polyethylene, an ethylene-vinyl acetate copolymer, zinc oxide, stearic acid, sulfur, high-abrasion-resisting furnace black, carbon nanotubes, nano calcium carbonate, montmorillonoid, zirconium diboride, calcium sulfate whiskers, lignocellulose short fibers, cotton short fibers, an accelerant M, an accelerant BZ, a poly-3-hydroxybutyrate-4-hydroxybutyrate, epoxy soybean oil, an anti-aging agent RD, an anti-aging agent MB, p-aminodiphenyl amine, gamma-epoxypropoxy propyltrimethoxysilicane and vinyltriethoxysilane. The high-strength and anti-impacting natural rubber cable sheathing material disclosed by the invention is high in strength, good in anti-impacting performance, excellent in anti-aging performance and long in service life.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a high-strength impact-resistant natural rubber cable sheath material. Background technique [0002] With the development of my country's petrochemical, communication, transportation, construction, electric power and other industries, the demand for cables in power plants, substations, smelting and petrochemical industries has been extremely high in recent years, and at the same time higher requirements have been put forward for the performance and quantity of cables. Therefore, the materials used to make cables are gradually high-grade, specialized and specialized. As the outermost material of the cable, the cable sheath has a great influence on the comprehensive performance of the cable. It not only requires excellent physical properties, such as tensile strength, elongation at break, etc., but also requires good heat resistance and Anti-aging properties, etc. Although...
