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 flame retardant cable sheath material. The flame retardant cable sheath material comprises the following raw materials by weight: 97 to 100 parts of chloroprene rubber SN23, 10 to 15 parts of chlorinated polyethylene, 15 to 20 parts of hydrotalcite, 8 to 10 parts of magnesium carbonate, 18 to 25 parts of a modification filling material, 4 to 5 parts of trioctyl trimellitate, 3 to 4 parts of methylpentachlorostearate, 1 to 2 parts of an anti-aging agent ODA, 1 to 2 parts of a promoter TMTM, 1 to 2 parts of 3-aminopropyltrimethoxysilane, 3 to 4 parts of ethylene bis stearamide, 2 to 4 parts of aluminum tripolyphosphate, 1 to 2 parts of ferrocene, 1 to 2 parts of an anti-oxidant 168 and 1 to 3 parts of benzotriazole. 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 sheathing material, in particular to a flame-retardant 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. Improving its storage stability further improves the performance of the cable sheathing materi...
