Wearproof and stretch-proof cable jacket material

Abstract

The invention discloses a wearproof and stretch-proof cable jacket material, prepared from the following raw materials in parts by weight: 40 to 50 parts of methyl vinyl silicone rubber, 20 to 30 parts of urea resin, 5 to 15 parts of butadiene styrene rubber, 5 to 15 parts of fluorinated silicone rubber micro powder, 1 to 3 parts of cerium oxide, 3 to 6 parts of organic calcium, 5 to 10 parts of glass fiber, 1 to 7 parts of anti-hydrolysis agent, 2 to 5 parts of vulcanizing agent, 8 to 15 parts of pine tar oil, 4 to 8 parts of heavy crystalline silicon powder, 3 to 10 parts of ethylene vinylacetate copolymer, 2 to 5 parts of compatilizer, 1 to 3 parts of flame retardant and 8 to 18 parts of wearproof powder. The wearproof and stretch-proof cable jacket material has the advantages of beingcorrosion-proof, stretch-proof and long in service life, and the like, the mechanical strength of a cable jacket can be effectively improved, the cable jacket is prevented from being broken in a use process, the service life of a cable is prolonged; according to the cable jacket material, by using the fluorinated silicone rubber micro powder and the cerium oxide, a cable material has excellent heat resistance, cold resistance, high voltage resistance and weathering aging resistance, and further has excellent hydrogen solvent resistance, oil resistance and acid and alkali resistance and a lowersurface energy property.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a wear-resistant and tensile-resistant cable sheath material. Background technique [0002] Plastics for wire and cable insulation and sheathing are commonly known as cable materials, including rubber, plastic, nylon and other varieties. Cable material production enterprises take cable production enterprises as users, as long as there is a demand for wire and cable, there will be a market for cable materials. Except for bare wire products such as steel-cored aluminum stranded wire and electromagnetic wire, almost all wire and cable products require an insulation layer. At present, there are nearly 5,000 wire and cable production enterprises in my country, and there is also a huge demand for wire and cable products for urban and rural power grid transformation, western development, and large-scale upgrading of communication facilities. Therefore, from a period of time, ca...

Problems solved by technology

[0003] However, in the process of using cables, they are often erected in the air for power transmission, so that the cables in the air are often eroded by ultraviolet rays, causing premature cracking of the cables, affecting the cable transmission of the cables, and making people's Normal life is affected, which greatly shortens the service life of the cable, and some special industries need to be used on heavy machinery, and need to move continuously with the equipment, and constantly contact with the ground, walls and other objects. Conventional cables cannot meet its wear resistance requirements.

At the same time, the traditional single-cable sheath material selection is unreasonable, it cannot effectively protect the internal structure of the cable, and cannot be used for a long time
