Abstract

The invention relates to a thermoplastic polyimide cable material for nuclear power aviation. The thermoplastic polyimide cable material comprises, by weight, 5-30 parts of polyimide, 5-30 parts of polyetherimide, 30-70 parts of siloxane-containing polyetherimide, 5-30 parts of ether bond-containing polar resin, 5-30 parts of a liquid crystal polymer, 5-30 parts of non-polar crystalline resin, 5-30 parts of silicon resin, 5-20 parts of talcum powder, 0.2-1 part of a processing aid, 0.1-1 part of an antioxidant and 0.1-10 parts of an additive. Different types of polyimide base resins are mixedand used, and the polar resin containing ether bonds, the liquid crystal polymer, the non-polar crystalline resin, the silicon resin, the talcum powder and the like are used to improve the proecsing properties of the material, so the heat resistance and the processing properties are improved, and the radiation resistance, the high flame retardant property, the high insulating property and other comprehensive properties of the base material are also improved; and the cable material can be processed by using traditional thermoplastic cable processing equipment, so the cable processing technologyis simplified.

Description

technical field [0001] The invention relates to a cable material, in particular to a thermoplastic polyimide cable material for nuclear power aviation. Background technique [0002] At present, there are many types and quantities of cable materials used in nuclear power plants on the market, such as cross-linked polyolefin materials, ethylene-propylene rubber, low-smoke halogen-free flame-retardant materials, etc. In order to meet the needs of nuclear-grade cables, these cable materials contain a large amount of resistance Combustion agent, anti-radiation agent, etc., the addition of such a large number of components leads to a decrease in the mechanical properties of the material and an increase in processing difficulty. Cable materials for nuclear power plants must not only have good electrical properties and mechanical and physical properties, but also have excellent heat resistance and radiation resistance. [0003] Polyimide is resistant to high temperature, low temper...
