Cable insulation layer material long in service life and excellent in mechanical property

Abstract

The invention discloses a cable insulation layer material long in service life and excellent in mechanical property. The cable insulation layer material is prepared from, by weight, 40-55 parts of polyethylene, 15-30 parts of ethylene vinyl acetate, 30-40 parts of modified polypropylene, 1-2.3 parts of polydimethylsiloxane with carboxyl as an end group, 1-2 parts of dibenzoyl peroxide, 0.5-1.2 parts of trimethyol propane triacrylate, 1-2 parts of triallyl cyanurate, 1.2-2.3 parts of zinc dimethacrylate, 1-1.5 parts of an anti-aging agent DFC-34, 0.2-0.7 part of poly(1,2-dihydro-2,2,4-trimethyl-quinoline), 1-1.8 parts of an antioxidant 168, 0.2-0.9 part of sorbitol, 0.5-1.8 parts of hydroxyl silicone oil, 0.4-0.9 part of magnesium stearate, 1-3 parts of zinc stearate, 2-7 parts of a polyamide hot-melt adhesive and 40-60 parts of a composite filler. The cable insulation layer material is good in thermal stability, good in mechanical property and long in service life.

Description

technical field [0001] The invention relates to the field of cables and technology, in particular to a cable insulating layer material with long service life and excellent mechanical properties. Background technique [0002] With the rapid development of the economy, the demand for cable insulation materials is increasing, and the requirements are getting higher and higher. Traditional cable materials are facing huge challenges. The insulation layers of traditional cables are generally plastic materials. And when it is affected by heat energy, mechanical energy, light energy and radiation energy during use, the thermal stability and mechanical properties of the plastic cannot meet the requirements, resulting in corrosion of other components inside the cable insulation layer, and the cable cannot operate normally. At present, the thermal stability is good. , good mechanical properties, and long service life of plastic materials for insulating layers of cables has been highly ...
