Wire insulation layer and preparation method thereof

Abstract

The invention provides a wire insulation layer and a preparation method thereof. The wire insulation layer is prepared from components as follows: epoxy resin, PVC (polyvinyl chloride), ethylene propylene rubber, a glycerol liquor, a plant extract, modified bentonite, carbon black, aluminum hydroxide, zinc oxide, ethyl salicylate, a stabilizer, an antioxidant, a curing agent, an additive and a coupling agent. A prepared insulating material has excellent ageing resistance and mechanical performance, good insulating effect and better application prospects and prolongs the service life of a wire.

Description

technical field [0001] The invention belongs to the technical field of insulating materials, and in particular relates to a wire insulating layer and a preparation method thereof. Background technique [0002] Wires are mainly used to transmit electric energy, magnetic energy, electric signals and realize the conversion of electromagnetic energy. They are the main carrier of electric power transmission and are widely used in electrical equipment, lighting circuits, household appliances and other fields. Wires usually consist of a cable core that transmits power or electrical signals and a sheath that protects and insulates. The quality of wire insulation materials directly affects the quality of the project, the daily life of consumers and even the life and property safety of the majority of residents. However, although there are many types and large quantities of wire insulation materials at present, they still have certain defects in terms of performance. If these problem...

Problems solved by technology

However, although there are many types and large quantities of wire insulation materials at present, they still have certain defects in terms of performance. If these problems are not handled properly, they will cause considerable safety hazards.

[0003] Due to the particularity of the wire use environment, more stringent and diverse requirements are put forward for wire insulation materials, which should have good insulation, flexibility, wear resistance, temperature resistance, flame retardancy, etc., otherwise it will cause wire insulation The performance of the material will change, and even lose its use value

However, traditional wire insulation materials have problems such as poor wear resistance and aging resistance. Wire insulation materials are prone to friction damage when dragged on the road, swayed on buildings or in mines, and are prone to aging phenomena such as embrittlement when used for a long time. It brings a lot of inconvenience to the practical application
