Abstract

The invention provides a production method for an insulation material applied to power cables used for ships. The production method comprises the following steps: feeding ethylene propylene diene monomer and chlorosulfonated polyethylene into an internal mixer and carrying out internal mixing at 102 to 108 DEG C for 35 to 50 min; then feeding ziram, alkylphenol disulfide, methyl-2-mercaptobenzimidazole, 2,6-di-tert-butyl-p-methylphenol into the internal mixer and carrying out uniform mixing; then adding 3-aminopropylmethyldiethoxysilane, trithiocyanuric acid, carbon black, bis(2,2,6,6-tetramethyl-4-piperidyl)sebacate and zinc stearate into the internal mixer, and carrying out uniform mixing so as to obtain a rubber compound; subjecting the rubber compound to turning-over and mixing with anopen mill 4-5 times and then carrying out rubber discharging so as to obtain a rubber sheet; and drying the rubber sheet so as to obtain an insulation material sheet. According to the invention, theinsulation material is improved so as to enhance the flame retardant performance of the power cables used for ships.

Description

technical field [0001] The invention belongs to the field of electric cables, and in particular relates to a production method of insulating materials for marine power cables. Background technique [0002] With the development of science and technology, the requirements for cables matching ships are getting higher and higher. The flame retardant cables usually used basically use flame retardant insulating materials, flame retardant tapes, flame retardant fillers, and flame retardant sheath materials. Its shortcoming is: when breaking out of fire, the performance that cable prevents flame from spreading is not strong, and flame spreads to insulating layer easily, causes very big hidden danger to the safety of ship and personnel. Contents of the invention [0003] The invention aims to provide a method for producing insulating materials for marine power cables, and improves the flame retardancy by improving the insulating materials. [0004] A method for producing an insul...
