Problems solved by technology

Marine cables often need to withstand sunlight exposure during the day and high-power lamps and lanterns at night. The ultraviolet radiation they suffer will accelerate aging, reduce insulation performance, and affect the safety and life of use. Often the service life of the cable is shorter than the design of the ship. service life, affecting the use of ships
At the same time, because marine cables generally use printing numbers on the insulating surface as the method of marking the insulating cores of multi-core cables, the insulating rubber in the prior art often uses carbon black as a reinforcing agent in order to increase the mechanical strength, and carbon black will seriously affect the insulating rubber. The whiteness will cause the insulated color and the printed digital logo to be clearly distinguished, which will bring inconvenience to the construction and even the safety of electricity use.
[0003] The Chinese invention patent with the publication number CN 102344612A discloses an ethylene-propylene rubber cable insulation material for ships and oceans. It uses ordinary ethylene-propylene rubber for insulation and does not have UV aging resistance. At the same time, it uses tinned copper wire braided armor layer. Expensive, not conducive to controlling manufacturing costs
[0004] The Chinese invention patent with the publication number CN 101656124A discloses a low-smoke and halogen-free power or control cable insulated by ethylene-propylene rubber for ships. Toxic performance, does not have the anti-ultraviolet aging performance, can not meet the anti-ultraviolet requirements for cables required by the current ship code update, in the operating environment of ships with ultraviolet rays, the service life is short, and in the long run, it will cause high costs for shipbuilding

Abstract

The invention relates to a whitening ultraviolet-proof ethylene-propylene rubber insulation power cable for ships and a manufacturing method thereof. The cable is characterized in that a whitening ultraviolet-proof ethylene-propylene rubber insulation layer is extruded at the periphery of a tin-plated annealed stranded copper conductor to form an insulation wire core; a plurality of insulation wire cores are stranded to the right to form a cable core; and then an inner lining layer is extruded, a copper alloy wire weaving armor layer is coated, and an outer sheath is extruded successively. The insulation layer is prepared from the following raw material components: 12 parts of Keltan5508, 8 parts of Keltan21, 0.4-0.6 parts of TAIC, 0.5-0.8 parts of DCP (Dicumyl Peroxide), 0.3 -0.6 part of Ager MB, 0.1-0.2 parts of anti-aging agent 2246, 0.8-1.2 parts of oxidation zinc, 0.1-0.3 parts of stearic acid; 1-1.5 parts of a rutile-type titanium dioxide, 10-12 parts of lightweight calcium carbonate, 10-12 parts of ultrafine talcum powder, 2-3 parts of 38# cylinder oil, 2-3 parts of vapor-phase-method hydrated silica, 0.05-0.1 parts of ultraviolet absorbent UV-326, and 0.1-0.3 parts of coupling agent A-174. The insulation layer of the cable is white in color, good in mechanical property, excellent in anti-ultraviolet irradiation and anti-aging performance, and long in service life.
