Abstract

The invention relates to a high-strength high-temperature-resistant oil-resistant cable material in the technical field of cable materials. The cable material is prepared from the following componentsin parts by weight: 30-40 parts of a modified ethylene-vinyl oxalate copolymer, 50-62 parts of silicone rubber, 15-20 parts of bisphenol A polyoxyethylene ether, 62-80 parts of a nano flame retardant, 2.8-3.2 parts of a sensitizer, 1-2 parts of a silane coupling agent, 0.8-1.2 parts of an antioxidant, 1.6-1.8 parts of a silicon lubricant, 0.8-1.8 parts of a colorant and 3.8-4.2 parts of molybdenum oxide. The main chain of the modified ethylene-vinyl oxalate copolymer is a saturated polar ester group, the side chain contains a large number of unsaturated double bonds, the unsaturated double bonds improve the stability of the material, the high strength and high temperature resistance of the cable material are improved; the repulsion phenomenon between the saturated polar ester group and oils occurs, so that the oil resistance of the cable material is realized; the silicon rubber and the bisphenol A polyoxyethylene ether are matched with each other, so that the high-strength, high-temperature-resistant and oil-resistant properties of the cable material are further improved.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a high-strength, high-temperature, oil-resistant cable material. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and is often twisted around a center. Insulating covering. The cable has the characteristics of internal electrification and external insulation. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multi-strand wires and insulation layers, and are used to connect circuits, electrical appliances, etc. [0003] The amount of waste plastics produced in my country every year is about 16 million tons. Si...
