Abstract

The invention discloses an antifreeze high-temperature resistant cable material and a preparation method thereof. The antifreeze high-temperature resistant cable material is prepared from the following raw materials in parts by weight: 25-35 parts of dicyclopentadiene phenol epoxy resin, 5-10 parts of polyethylene oxide alkyl phenyl ether, 20-30 parts of polypropylene resin, 4-8 parts of tetraethoxysilane, 5-7 parts of sodium molybdate, 2-4 parts of modified kaolin, 3-5 parts of modified kieselguhr, 1-3 parts of glass fiber and 3-5 parts of ammonium heptamolybdate and triethanolamine in a weight part ratio of (2-4):1. The cable material disclosed by the invention experiences little parameter change in an extremely cold condition and is suitable for cold conditions; and meanwhile, the influence on the cable material at a high temperature of 120 DEG C is also detected, the fluctuation of performance parameter change in 100 days is relatively little, and the cable material is suitable for long-term use in high-temperature conditions.

Description

technical field [0001] The invention belongs to the field of power cables, and in particular relates to a frost-resistant and high-temperature resistant cable material and a preparation method thereof. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires. Each group of wires is insulated from each other, and is often twisted around a center, and the entire outside is covered with a highly insulating covering. The cable has the characteristics of internal electrification and external insulation. [0003] At present, cables are widely used in different regions and time and space, including under extreme temperature conditions. Most cables are placed between two utility poles and exposed to the outside. The department has extremely high requirements on the performance of the cables, which should have good high temperature and cold resistance. Therefore, how to maintain better performance parameters under extreme te...
