Abstract

The invention discloses a sheath rubber for middle and high voltage cables used for petrochemical apparatus motion, and manufacture method for the sheath rubber, belonging to the field of cables. The raw materials of the rubber are: 15 parts of chlorinated polyethylene rubber CM325, 15 parts of chlorosulfonated polyethylene H40, 0.4-0.6 parts of a vulcanizing agent DCP, 0.2-0.3 parts of a vulcanizing agents TAIC, 1.0-1.5 parts of magnesium oxide, 1.0-2.0 parts of an activator polyethylene glycol, 0.2-0.4 parts of an antioxidant NBC, 0.1-0.2 parts of an antioxidant HS-911, 2.0-3.5 parts of plasticizer DOS, 3-5 parts of fire retardant antimonony oxide, 2-4 parts of filler carbon black, 15-20 parts of powered talcum, and 0.1-0.3 parts of lead stearate. The method comprises the steps of: mixing the CM352 raw rubber for 2-3 minutes; adding H40 and mixing the mixture uniformly; then adding the rest of the raw materials except the vulcanizing agents to the mixture in sequence and mixing for 3-5 minutes; after the obtained mixture being mixed uniformly, unloading, sheeting, rubber filtering, and cooling the obtained mixture; and at last adding the vulcanizing agents and mixing uniformly to get a final product. The rubber has the advantages of good mechanical property, aging resistance and oil resistance, which can satisfy the usage requirements of middle and high voltage cables used for petrochemical apparatus motion.

Description

technical field [0001] The invention relates to a cable, in particular to a medium and high voltage cable sheath rubber for petrochemical equipment movement. The invention also relates to a method for manufacturing medium and high voltage cable sheath rubber for petrochemical equipment movement. Background technique [0002] Liquefied natural gas ships are known as the jewel in the crown of shipbuilding. Along with the development of petrochemical marginal oil and gas fields, they have promoted the construction and development of LNG-FPSO, a floating LNG production, storage and transportation device that integrates LNG production, storage and unloading, as a new project The particularity of the industry and its working environment full of flammable and explosive oily gas has extremely high requirements for supporting cables. The existing medium and high voltage cables cannot meet the comprehensive performance of stability, shielding, softness, oil resistance and corrosion re...
