Abstract

The invention belongs to the field of electric power materials, and concretely discloses a high-strength high-toughness cable sheath material. The high-strength high-toughness cable sheath material is prepared from the following raw materials in parts by weight: 1-2 parts of quartz sand, 1-2 parts of lithium bentonite, 1-2 parts of attapulgite, 1-2 parts of molybdenum disulfide, 2-3 parts of ethyl glutarate, 3-4 parts of graphite, 3-4 parts of silicon nitride, 5-7 parts of triphenyl phosphate, 6-8 parts of silicon carbide, 7-10 parts of egg shell, 7-10 parts of borax, 8-12 parts of polycarbonate, 8-12 parts of polyethylene wax, 8-12 parts of brominated polystyrene, 30-50 parts of chlorinated butyl rubber, and 30-50 parts of ethylene-propylene-diene rubber. According to the technical scheme, a rubber material is modified, the raw material compatibility is reasonable, and the strength and the toughness of the rubber are greatly improved.

Description

technical field [0001] The invention belongs to the field of power materials, and specifically discloses a high-strength and high-toughness cable sheathing material. Background technique [0002] With the acceleration of the industrialization process, rubber is becoming more and more important in life, and the relationship between rubber and people is getting closer and closer. All kinds of rubber can be seen in various fields of life such as food, commodity storage, culture, education and sports. With the increasing status of rubber in life, the quality of rubber has attracted more and more attention, especially the research and development of rubber with special properties such as high strength, high toughness, and anti-aging has long been highly concerned by professionals in various fields. . As the outer protective layer of the cable, the cable sheath is most vulnerable to extrusion and impact from external forces. If the strength and toughness of the cable sheath ar...
