Abstract

The invention discloses a rubber insulation material for a rubber sleeve power cable with the rated voltage of 35 kV or above. The rubber insulation material is prepared from, by weight, 70-90 parts of ethylene propylene diene monomers, 30-40 parts of methyl vinyl silicone rubber, 20-30 parts of ethylene-butene elastomers, 2-4 parts of paraffin, 11-15 parts of paraffin oil, 1-2 parts of an anti-aging agent MB, 1-2 parts of an anti-aging agent 264, 4-8 parts of zinc oxide, 0.5-1.5 parts of stearic acid, 10-15 parts of modified calcium carbonate, 110-130 parts of modified superfine kaolin, 2.5-4.5 parts of dicumyl peroxide, 1.5-3.5 parts of triallyl isocyanurate, 10-20 parts of epoxidized soybean oil, 8-10 parts of tributyl citrate, 8-12 parts of micro-capsulated red phosphorus, 10-15 parts of melamine cyanurate, 2-4 parts of a Ca-Zn compound stabilizer and 0.5-2 parts of vinyltriethoxysilane. The rubber insulation material is good in electrical insulating property and high in mechanical property.

Description

technical field [0001] The invention relates to the technical field of insulating materials, in particular to a rubber insulating material for a rubber-sheathed power cable with a rated voltage above 35kV. Background technique [0002] At present, the production and commercialization of ethylene-propylene rubber insulating materials and shielding materials for medium and high-voltage cables in foreign countries are quite mature, such as: IC4728B of Indianapolis is 110kV ethylene-propylene rubber insulating material; Brugg's BCR230 is 150kV ethylene-propylene rubber insulating material. [0003] Insulation and shielding materials for medium and high voltage cables in my country mainly use cross-linkable polyethylene, and some ethylene-propylene rubber insulation and shielding materials are also imported. The voltage level of rubber insulated cables for some mining machinery in my country has reached 10kV. With the increasing demand for medium and high voltage rubber insulat...
