Abstract

The invention discloses a high-temperature-resistant vapour-resistant sheath material for nuclear power station cables and a preparation method thereof. The sheath material is prepared from the following raw materials in parts by weight: 50-70 parts of methyl vinyl phenyl polysiloxane rubber, 20-30 parts of ethylene-propylene-diene monomer, 15-25 parts of poly(thiophenylene), 10-15 parts of C5 petroleum resin, 20-30 parts of acetylene black, 1-2 parts of zinc oxide, 2-3 parts of stearic acid, 3-5 parts of triallyl isocyanurate, 15-20 parts of magnesium hydroxide, 10-15 parts of antimony trioxide, 5-10 parts of zinc stannate, 1-2 parts of zine stearate, 1-2 parts of barium stearate, 1.5-2.5 parts of gamma-methacryloxy propyl trimethoxyl silane, 10-15 parts of dimethyl phthalate and the like. The cable material of the invention has excellent performances comprising high temperature resistance, vapour resistance, radiation resistance, corrosion resistance, aging resistance and the like, good flame retardant efficiency, does not spread flame and is automatically extinguished after on fire, has low smoke, no halogens, no toxicities and no corrosive gases, and is capable of satisfying special environmental requirements of special nuclear power stations.

Description

Technical field [0001] The invention relates to a high temperature resistant water vapor sheath material for nuclear power station cables and a preparation method thereof, and belongs to the technical field of cable materials. Background technique [0002] Nuclear power plant cables are an important electrical component of nuclear power plants, and the conditions of their use locations are relatively harsh. When a high-energy tube rupture accident or a water loss accident occurs in a nuclear power plant, the cable will be subjected to the dual effects of the impact of high temperature and high pressure steam and corrosive chemicals, resulting in failure of the sheath material and affecting the normal operation of the nuclear power plant. Summary of the invention [0003] The purpose of the present invention is to provide a high temperature resistant water vapor sheath material for nuclear power plant cables and a preparation method thereof in view of the deficiencies of the prior ...
