Problems solved by technology

The cable floats on the water surface through the buoy, and transmits power to the mining equipment. In such an application, it often has to withstand high wind speed, strong ultraviolet radiation, high salt pollution, brine immersion, and severe acid, alkali, oil, and salt corrosion. After a long-term use of ordinary cables, a thick layer of crystalline salt will condense on the surface of the cable, increasing t

Abstract

The invention discloses a salt-fog preventing coating for a cable, comprising the following components based on portions by weight: 100 portions of silicon rubber, 20-40 portions of No.2 fumed silica, 2-6 portions of diphenyl silanediol, 0.5-1 portion of benzoyl peroxide, 15-35 portions of zinc oxide, 0.5-1 portion of ultraviolet radiation resistant agent, 4-8 portions of olefin, 3-6 portions of olefin oil and 4-6 portions of transformer oil. The invention also discloses a preparation method of the salt-fog preventing coating for the cable. The salt-fog preventing coating for the cable can well prevent strong ultraviolet radiation from irradiating the cable and prevent high salt dirty, brine dipping, acid, alkali, oil, salt, and the like from seriously eroding the cable. In a process of using the coating, the olefin and the transformer oil can be gradually separated out on the surface of the cable so that crystal salt caused by seawater can be effectively prevented from adhering on the surface of the cable, the cable can be well protected, and the service life of the cable can be greatly prolonged.

Description

technical field [0001] The invention relates to an anti-salt mist coating for cables and a preparation method thereof, belonging to the field of preventing salt mist erosion of electrical connection cables of ocean mining ships and oil drilling platforms working on sea surfaces and salt lakes. Background technique [0002] Salt-spray resistant cables are used for power connections on marine exploration vessels and oil rigs. The cable floats on the water surface through the buoy, and transmits power to the mining equipment. In such an application, it often has to withstand high wind speed, strong ultraviolet radiation, high salt pollution, brine immersion, and severe acid, alkali, oil, and salt corrosion. After a long-term use of ordinary cables, a thick layer of crystalline salt will condense on the surface of the cable, increasing the weight of the cable, resulting in an increase in the weight of the cable, corroding the surface of the cable, and in severe cases, the cable ...
