Problems solved by technology

It has high tensile strength, elongation and reversible crystallinity, good adhesion, aging resistance, heat resistance, oil resistance and chemical corrosion resistance. It can be used for a long time at 80-100 °C and has a certain flame retardancy. However, the disadvantage is that the storage stability is poor. Therefore, using neoprene as a cable sheath material can ensure that it has strong heat resistance, aging resistance, oil resistance, corrosion resistance, etc., and by adding some modified fillers. Improving its storage stability further improves the performance of the cable sheathing material

Abstract

The invention discloses a low temperature resistant cable sheath material comprises the following raw materials, in parts by weight: 95-102 parts of chloroprene rubber A90, 12-14 parts of polyurethane, 17-20 parts of bauxite, 6-7 parts of an alum powder, 16-24 parts of a modified filler, 3-6 parts of oxidized polyethylene wax, 5-7 parts of poly(1,2-propylene glycol adipate), 1-2 parts of an anti-aging agent MB, 1-2 parts of magnesium oxide, 1-2 parts of anilino-methyl-triethoxysilane, 3-4 parts of extylene diamine tetra (mextylene phosphonic acid) sodium, 1-2 parts of 1,6-hexanediamine, 0.8-1 part of a vulcanizing agent DCBP, and 1-2 parts of decabromodiphenyl ether. The produced cable sheath material is excellent in physical properties, stable in size and low in shrinkage rate, has strong pulling and promoting strength, strong anti-tear strength and strong resilience force performance, and has good properties of oil resistance, heat resistance, flame resistance, sunlight resistance, ozone resistance, acid and alkali resistance, and chemical reagent resistance. The modified filler has good dispersion and low surface tension, and thus the modified filler further improves the tensile strength and the stress at definite elongation of the cable material, reduces heat-generating and compression permanent deformation, not only can delay aging speed of the cable material, but also can resist acid and alkali corrosion and reduce production cost.

Description

technical field [0001] The invention mainly relates to a cable sheathing material, in particular to a low temperature resistant cable sheathing material. Background technique [0002] Neoprene has good physical and mechanical properties, oil resistance, heat resistance, flame resistance, sunlight resistance, ozone resistance, acid and alkali resistance, and chemical reagent resistance. It has high tensile strength, elongation and reversible crystallinity, good adhesion, aging resistance, heat resistance, oil resistance and chemical corrosion resistance. It can be used for a long time at 80-100 °C and has a certain flame retardancy. However, the disadvantage is that the storage stability is poor. Therefore, using neoprene as a cable sheath material can ensure that it has strong heat resistance, aging resistance, oil resistance, corrosion resistance, etc., and by adding some modified fillers.
