Abstract

The invention discloses salt corrosion resistance twisted cable insulation rubber used for ocean wind power and a preparation method of the salt corrosion resistance twisted cable insulation rubber. By weight, raw materials comprise 8 parts of Keltan5508, 12 parts of DutralTER4044, 5-7 parts of EP-20, 0.5-0.7 part of DCP, 0.3-0.5 part of TAC, 0.2-0.4 part of HVA-2, 0.2-0.4 part of RD, 0.2-0.4 part of MB, 0.2-0.4 part of KH-550, 2.1-2.5 part of hydration zinc borate, 1-1.5 parts of antimony trioxide, 25-40 parts of aluminum hydroxide, 0.8-1.2 part of red lead, 0.5-1 part of stearic acid, 1.5-2 parts of nan-zinc oxide, 2-5 parts of paraffin oil Sunpar2280, 0.5-1 part of chlorinated paraffin-52, and 1-3 parts of hydration silicon dioxide. According to the method, firstly, the EPDM rubber Keltan5508, the DutralTER4044 and the EP-20 are mixed for 1-1.5 minutes, and then other components except for a vulcanizing agent and a co-vulcanization agent are added. After mixing is carried out for 7-8 minutes, discharging and airing are carried out for more than 24 hours. Then the rubber materials are mixed for 2-3 minutes, the vulcanizing agent and the co-vulcanization agent are added at the last 20 seconds, and the mixed materials are loaded on an open mill for milling, triangular injection molding and square injection molding and then sheeted. The insulation rubber is good in mechanical performance, anti-corrosion performance and anti-aging performance and long in service life.

Description

technical field [0001] The invention relates to a cable insulating rubber, in particular to a salt-rot and torsion-resistant cable insulating rubber for marine wind power. The invention also relates to a method for manufacturing the salt-corrosion-resistant and torsion-resistant cable insulating rubber used in marine wind power. Background technique [0002] With the maturity of land-use wind power utilization, the country has begun to promote the use of offshore wind power, but at present there is no cable dedicated to offshore wind power that can fully meet the operating conditions of offshore wind power to match it, and most of them are matched with cables originally used for land-use wind power It is used for offshore wind power, or a cable with certain performance required by the cable for offshore wind power is used. However, the performance of cables for land-use wind power does not take into account the special environment of offshore wind power, especially does not...
