Abstract

The invention discloses an insulation rubber for longitudinal water-tight demagnetization cables used for ships and a manufacture method for the insulation rubber, belonging to the field of cables. The raw materials of the rubber are 15 parts of terpolymer EP rubber K21, 5 parts of terpolymer EP rubber 4045M; 0.5-0.6 parts of a vulcanizing agent DCP, 0.2-0.3 parts of a vulcanizing agent TAIC, 0.7-0.9 parts of an antioxidant MB, 0.2-0.3 parts of an antioxidant RD, 1.0-2.0 parts of paraffin oil, 1-2 parts of chlorinated paraffin-52, 0.5-1.0 parts of microcrystalline paraffin, 1.0-2.0 parts of zinc oxide, 0.3-0.5 parts of eleaostearic acid, 8-11 parts of powdered talcum, 1.0-1.5 parts of gas phase method silica, and 7-9 parts?of calcined pottery clay. First, mixing the raw rubbers of the terpolymer EP rubbers K21 and 4045 in an internal mixer; then adding the rest of the raw materials except the vulcanizing agents in sequence and mixing for 14-16 minutes, and after the obtained mixture being mixed uniformly, loading the obtained product on an open mill to make triangular bags eight times, followed by rubber sieving and sheets making. The insulation rubber has the advantages of good insulative and mechanical properties, aging resistance and oil resistance, which can satisfy the usage requirements of the longitudinal water-tight demagnetization cables used for ships.

Description

technical field [0001] The invention relates to a cable, in particular to a longitudinal watertight degaussing cable insulation rubber for ships. The invention also relates to a manufacturing method of the longitudinal watertight degaussing cable insulating rubber for ships. Background technique [0002] Due to the importance of stealth during navigation, ships, especially underwater ships, especially need to prevent magnetic mine attacks. For this reason, the hull needs to be degaussed frequently. Fixed degaussing can be degaussed at the degaussing station, but for the induced magnetic field generated by the underwater ship that is in the process of sailing for a long time, it needs to be degaussed with the help of the degaussing system installed outside the ship itself. However, due to the particularity and complexity of the underwater ship's navigation environment, ordinary degaussing cables cannot simultaneously meet the technical requirements for both longitudinal seal...
