Whitening ultraviolet-proof non-shield instrument cable for ships and manufacturing method thereof

Abstract

The invention relates to a whitening ultraviolet-proof non-shield instrument 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 0.35-2.5mm<2> tin-plated annealed stranded copper conductor to form an insulation wire core; every two insulation wire cores are twisted to form twisted groups; all the twisted groups 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 parts of Ager MB, 0.1-0.2 parts of an 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 UV-326, and 0.1-0.3 parts of 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.

Description

technical field [0001] The invention relates to an instrument cable, in particular to a whitening and anti-ultraviolet marine unshielded instrument cable. The invention also relates to a manufacturing method of the whitening and anti-ultraviolet marine non-shielding instrument cable. Background technique [0002] With the serious situation of shipbuilding, everyone pays more attention to cost control, and has higher requirements on the performance and service life of various supporting equipment. 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. life, affecting the use of ships.

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 electrici
