Marine oil-resistant and paint-aging-resistant independent shielding power cable and manufacturing method thereof

Abstract

The invention relates to a marine oil-resistant and paint-aging-resistant independent shielding power cable and a manufacturing method thereof. Power cable cores are sequentially extruded and wrapped on the periphery of a twisted copper conductor, wherein each power cable core is formed by an insulation layer, a wrapping shielding inner wrapping belt, a cladding independent shielding layer and a wrapping shielding outer wrapping belt; after gaps among a plurality of power cable cores are filled with flame-retardant polypropylene fiber for core filling, the whole is intertwisted to form the power cable core; a high-heat-resistance coefficient flame retardant fire-resistant longitudinal wrapping belt is sequentially wrapped on the periphery of the cable core, then, a armored braiding layer is cladded, talcum powder is coated, and an oil-resistant and paint-aging-resistant outer sheath is extruded and wrapped. The outer sheath is prepared from the following ingredients in parts by weight: 15 parts of PVC-SG2, 5 parts of LEVAPREN 500HV rubber, 4 to 7 parts of polypropylene adipate, 2 to 3 parts of epoxidized soybean oil, 0.6 to 1 part of lead sulfate tribasic, 1 to 1.5 parts of dibasic lead phthalate, 0.05 to 0.1 part of diphenol propane, 2 to 4 parts of Elvaloy 742, 1 to 3 parts of antimonous oxide, 0.1 to 0.5 part of chlorinated paraffin 52 and 0.3 to 0.5 part of ferrocene. The cable can achieve the oil-resistant and paint-aging-resistant effects.

Description

technical field

[0001] The invention relates to a power cable, in particular to a marine oil-resistant, paint-resistant and aging-resistant independent shielded power cable. The invention also relates to a method for manufacturing a marine oil-resistant, paint-resistant and aging-resistant independent shielded power cable. Background technique

[0002] The cables in the prior art do not have paint aging resistance, and will accelerate aging during long-term contact with the paint, shortening the service life of the cables, thereby causing electrical safety hazards.

[0003] After the ship has been used for a certain period of time, it is necessary to carry out anti-corrosion treatment on the steel plate, and anti-corrosion paint is an important means of anti-corrosion. Due to the compact structure of the ship and the small space, it is difficult to avoid the paint spraying on the surface of the cable during the process of applying anti-corrosion paint. In the past, the cab...
