Abstract

The invention discloses a high-strength heat-resistant cable jacket material and a preparation method thereof and belongs to the technical field of cable jacket materials. The high-strength heat-resistant cable jacket material is prepared from the following raw materials: nitrile rubber, EPDM, chlorosulfonated polyethylene, a vulcanizing agent, tetramethyl thiuram disulfide, benzoyl peroxide, an ethylene-vinyl acetate copolymer, zinc stearate, activated zinc oxide, N,N'-m-phenylene bismaleimide, highly dispersed white carbon black, modified sepiolite powder, nano silicon dioxide, hydroxyl silicone oil, calcined metakaolin powder, modified phenolic resin, antimonous oxide, magnesium hydroxide, an accelerant, an anti-aging agent and a plasticizer. The cable jacket material is high in strength, good in heat resistance, ageing-resistant and long in service life.

Description

technical field [0001] The invention relates to the technical field of cable sheathing materials, in particular to a high-strength heat-resistant cable sheathing material and a preparation method thereof. Background technique [0002] The cable sheath is an indispensable intermediate structural part of the cable, which plays the role of protecting the cable, ensuring the safety of the cable, and isolating the copper wire from water, air and other media to avoid leakage. PVC sheath is widely used in cable sheathing due to its soft texture, corrosion resistance, corrosion resistance, flame retardant, good oil resistance, and low price. However, the current ordinary PVC sheath has poor heat resistance, so its service life is short, and it is not suitable for use in harsh environments. [0003] After searching the existing technology, a Chinese patent (application number: 201210283037.0) discloses a formula for a composite wire and cable sheath material, including polystyrene, ...
