Abstract

The present invention discloses an aerial insulation cable material made from the following raw materials by weight: 60-80 parts of SG-3 type PVC (polyvinyl chloride), 20-30 parts of low density polyethylene, 15-25 parts of ethylene-vinyl acetate copolymer, 10-15 parts of bisphenol A type polycarbonate, 15-20 parts of magnesium hydroxide, 5-10 parts of butyl stearate, 4-8 parts of rapeseed oil, 1-2 parts of barium stearate, 2-3 parts of calcium stearate, 3-5 parts of diphenyl isooctyl phosphate, 4-6 parts of 2,2'-ethylenedioxydiethyl bis(2-ethylhexanoate), 8-12 parts of nano sepiolite powder, 15-25 parts of carbon black N660, 5-8 parts of a composite filler, 1-2 parts of catechol, 1-2 parts of dibutyltin dichloride and 5-10 parts of dibutyl isophthalate. The aerial insulation cable material is stable in quality, reliable in performance, excellent in weather resistance, aging resistance and electrical properties, good in toughness, tensile strength, and high temperature resistance, excellent in machining performance, and suitable for 1KV and below aerial cable insulating layers.

Description

technical field [0001] The invention relates to a cable material and a preparation method thereof, in particular to an overhead insulating cable material. Background technique [0002] Polyvinyl chloride (PVC) is widely used as the sheath material of outdoor overhead wires and cables due to its flame retardant, oil resistance, corona resistance, chemical corrosion resistance, good water resistance and processing performance. However, the existing polyvinyl chloride cable materials have poor weather resistance and aging resistance, and are prone to failure when exposed to high-altitude environments for a long time, resulting in huge economic losses. Contents of the invention [0003] The object of the present invention is to provide an overhead insulating cable material with excellent high and low temperature resistance, weather resistance and aging resistance. [0004] The technical scheme that the present invention adopts is as follows: [0005] An overhead insulating c...
