Abstract

The invention discloses whitening ultraviolet-proof cable insulating rubber and a manufacturing method of the rubber, and belongs to the field of cables. Raw materials comprises 12 parts of Keltan 5508, 8 parts of Keltan 21, 0.4-0.6 part of co-vulcanization agent TAIC, 0.5-0.8 part of vulcanizing agent DCP, 0.3-0.6 part of antiager MB, 0.1-0.2 part of antiager 2246, 0.8-1.2 parts of zinc oxide, 0.1-0.3 part of stearic acid, 1-1.5 parts of rutile type titanium dioxide, 10-12 parts of colloidal calcium carbonate, 10-12 parts of ultrafine talcum powder, 2-3 parts of cylinder oil of number 38, 2-3 parts of gas-phase-method silicon dioxide hydrate, 0.05-1 part of ultraviolet light absorber UV-326 and 0.1-0.3 part of coupling agent A-174. A filling agent, a reinforcing agent, a coloring agent, the antiager, the zinc oxide, the ultraviolet light absorber and the coupling agent are subjected to internal mixing first, ethylene propylene rubber is fed for mixing, rubber filtering, rolling, cooling are carried out, the stearic acid and the vulcanizing agent are fed for mixing, and then ethylene propylene rubber is fed for mixing, a triangular ladle is rammed, thin-passing process is carried out, and cutting and cooling are carried out for using. The insulating rubber is white in color, good in mechanical performance, good in ultraviolet light aging resistant performance and long in service life.

Description

technical field [0001] The invention relates to a cable insulating rubber, in particular to a whitening and anti-ultraviolet cable insulating rubber. The invention also relates to a manufacturing method of the whitening and anti-ultraviolet cable insulating rubber. 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. At the same time, since marine cables generally use printing numbers on the insulating surface as the method of marking the insulating cores of mult...
