High-wear resistance cable sheath material

Abstract

The invention discloses a high-wear resistance cable sheath material. The high-wear resistance cable sheath material comprises the following raw materials by weight: 90 to 100 parts of chloroprene rubber DCR114, 10 to 20 parts of EPDM 4770R, 15 to 20 parts of nanometer bauxite, 20 to 30 parts of a modification filling material, 8 to 10 parts of dioctyl sebacate, 3 to 4 parts of polypropylene adipate, 4 to 6 parts of acetyl triethyl citrate, 2 to 4 parts of zinc oxide, 6 to 8 parts of chlorinated paraffin, 2 to 3 parts of antimony trioxide, 2 to 4 parts of triphenyl phosphite, 1 to 2 parts of the anti-aging agent MB, 1 to 2 parts of the promoter CZ and 0.8 to 1 part of sulphur. The cable sheath material produced in the invention has excellent physical properties, a stable dimension, low shrinking percentage, high tensile strength, great tearing strength, strong resilience and good resistance to oil, heat, burning, sunlight, ozone, acid and alkali and chemical reagents; and the modification filling material provided by the invention has good dispersibility and low surface tension, enables tensile strength and stress at definite elongation of the cable sheath material to be further improved, reduces heat generation and compression set, delays the ageing speed of the cable sheath material, is capable of resisting acid and alkali and allows production cost to be reduced.

Description

technical field [0001] The invention mainly relates to a cable sheath material, in particular to a high wear-resistant cable sheath material. Background technique [0002] Neoprene rubber has good physical and mechanical properties, oil resistance, heat resistance, flame resistance, sunlight resistance, ozone resistance, acid and alkali resistance, and chemical resistance. It has high tensile strength, elongation and reversible crystallinity, good adhesion, aging resistance, heat resistance, oil resistance and chemical corrosion resistance. 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 and other characteristics. Improving its storage stability further improves the performance of the cable sheathing material. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a...

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
