Abstract

The invention discloses an anti-ultraviolet cable jacket material. The anti-ultraviolet cable jacket material is prepared from raw materials in parts by weight as follows: 50-70 parts of methylvinyl silicone rubber, 15-26 parts of EPDM rubber, 8-13 parts of neoprene M-40, 4-8 parts of polyoxyethylene abietate, 3-5 parts of dioctyl epoxytetrahydrophthalate, 4-9 parts of magnesium carbonate, 2-4 parts of ammonium molybdate, 25-29 parts of carbon black N550, 2-4 parts of chromium boride, 1-3 parts of zinc stearate, 1-2 parts of methyltin mercaptide, 1-2 parts of cresyl diphenyl phosphate, 4-6 parts of polyethylene wax, 10-15 parts of anti-ultraviolet agent UV-531, 5-10 parts of aluminium isopropoxide and 11-16 parts of composite filler. The cable jacket material has good physical and mechanical properties and excellent anti-ultraviolet performance and is resistant to oil, heat, fire, sunlight, ozone, aging, acid and base.

Description

technical field [0001] The invention relates to the field of cables, in particular to an anti-ultraviolet cable sheathing material and a preparation method thereof. Background technique [0002] The cable sheath is an indispensable intermediate structural part of the cable, which plays the role of protecting the cable, ensuring the safety of the cable, and isolating the copper wire from water, air and other media to avoid leakage. In order to ensure that the cable sheath has sufficient strength, a large amount of inorganic fillers are added to the existing cable sheath material, which leads to the disadvantages of the sheath material such as poor UV resistance and cannot meet the increasing market demand. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide an anti-ultraviolet cable sheathing material and a preparation method thereof. [0004] In order to realize the above-ment...
