Abstract

The invention discloses a radiation-resisting cable material and a preparation method thereof. The radiation-resisting cable is prepared from the following raw materials in parts by weight: 70-80 parts of SG-4 type PVC (Polyvinyl Chloride) resin, 25-35 parts of polyetherimide, 10-15 parts of ABS (Acrylonitrile Butadiene Styrene), 10-15 parts of magnesium hydrate, 5-10 parts of Phenoxycyclotriphosphazene, 8-12 parts of acetyltrioctylcitrate, 3-5 parts of microcrystalline wax, 4-8 parts of coumarone resin, 5-10 parts of calcium phosphate, 3-6 parts of epoxy octyl stearate, 10-15 parts of calcined clay, 4-8 parts of composite filler, 6-12 parts of precipitated barium sulphate, 0.5-1 part of imarcaptoacetate dioctyltin, 1-2 parts of zinc stearate, 3-6 parts of titanium dioxide, 0.3-0.5 part of a light stabilizer 622, 0.2-0.4 part of a light stabilizer 1084 and 0.5-0.8 part of an antioxidant 264. The cable material disclosed by the invention is excellent in physical and mechanical property, flame retardant property, radiation resistance property and electric property, is capable of working in severe environments in nuclear power plants, is long in service life, and can be widely applied to cables in match with wires in the nuclear power plants.

Description

technical field [0001] The invention relates to a cable material and a preparation method thereof, in particular to a radiation-resistant cable material and a preparation method thereof. Background technique [0002] Ordinary cables are not suitable for nuclear power plant cables due to their poor radiation resistance, and cannot cope with harsh radiation environmental conditions, resulting in short service life of the cables and potential safety hazards. At present, wires and cables improve the radiation resistance and other properties of the material by increasing the oxygen index of the insulating material of the sheath, or the material has shell-forming properties, but the physical and mechanical properties of the insulating material are greatly reduced. Contents of the invention [0003] The object of the present invention is to provide a radiation-resistant cable material and a preparation method thereof, which can improve the radiation-resistant performance of the c...
