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 cable sheath material with high storage stability. The cable sheath material comprises the following raw materials by weight: 98 to 104 parts of chloroprene rubber CR322, 7 to 9 parts of diethylene glycol benzoate, 3 to 4 parts of coumarone, 17 to 20 parts of meerschaum powder, 24 to 30 parts of a modification filling material, 1 to 2 parts of ethene diamine, 3 to 4 parts of phthalate, 3 to 5 parts of ammonium polyphosphate, 1 to 2 parts of N-(beta-aminoethyl)-gamma-aminopropyltrimethoxysilane, 1 to 2 parts of bis(2,4-dichlorobenzoyl) peroxide, 0.8 to 1 part a promoter TMTD, 2 to 4 parts of talcum powder, 3 to 4 parts of stearic acid and 1 to 2 parts of a promoter M. 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 cable sheathing material with high storage stability. 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 cab...
