Flame-retardant heat-resisting ageing-resistant cable sheath material

Abstract

The invention discloses a flame-retardant heat-resisting ageing-resistant cable sheath material. The cable sheath material comprises the following raw materials in parts by weight: 5-8 parts of polybutylene terephthalate (PBT), 20-25 parts of polyphenylene sulfone (PPSU) resin, 15-20 parts of polyethylene (PE), 10-14 parts of chopped glass fiber, 3-5 parts of asbestos fiber, 1-1.5 parts of alumina whiskers, 7-9 parts of montmorillonite, 10-12 parts of diatomite, 15-17 parts of plaster, 10-11 parts of magnesium hydroxide, 3-5 parts of melamine phosphate, 1-3 parts of zinc stearate, 0.7-1.3 parts of glycerol monostearate, 1.5-1.9 parts of epoxy soybean oil, and 2-3 parts of a silane coupling agent. The cable sheath material disclosed by the invention has the advantages of excellent heat resistance, excellent ageing resistance, high tensile strength, high shock strength and excellent flame-retardant property.

Description

technical field [0001] The invention relates to the technical field of cable sheath materials, in particular to a flame-retardant, heat-resistant and aging-resistant cable sheath material. Background technique [0002] With the development of the economy, the demand market for cables is broad, which promotes the progress of the production technology of cable materials. Cable materials are not only widely used, but also have special requirements for their performance indicators, such as insulation, tensile strength, service temperature, and flame retardancy. Performance and other indicators have strict requirements. Continuously improving the performance of cable materials is an urgent need for economic and social development. Traditional cable materials often have problems such as poor flame retardancy, high temperature deformation, poor mechanical properties, and short service life. It brings a lot of inconvenience to the actual use, and even threatens the safety of people'...

[0002] With the development of the economy, the demand market for cables is broad, which promotes the progress of the production technology of cable materials. Cable materials are not only widely used, but also have special requirements for their performance indicators, such as insulation, tensile strength, service temperature, and flame retardancy. Performance and other indicators have strict requirements. Continuously improving the performance of cable materials is an urgent need for economic and social development. Traditional cable materials often have problems such as poor flame retardancy, high temperature deformation, poor mechanical properties, and short service life. It brings a lot of inconvenience to the actual use, and even threatens the safety of people's lives and property. Therefore, it is urgent to change the original cable material formula and improve the material performance to meet the diverse needs of the cable market.
