A kind of high tensile cable sheath material

Abstract

The invention discloses a high-stretchproof cable sheath material. The material consists of the following raw material in parts by weight: 90-100 parts of chloroprene rubber CR121, 6-8 parts of di(2-ethylhexyl)-4,5-epoxytetrahydrophthalate, 4-6 parts of isophthalic acid ester, 5-7 parts of oxidized polyethylene wax, 2-3 parts of magnesium fluoride, 3-5 parts of ferrocene, 1-2 parts of an anti-aging agent aw, 1-2 parts of 2-benzimidazolethiol, 5-8 parts of dioctyl maleate, 1-2 parts of an accelerator DM, 3-4 parts of zinc borate, 20-30 parts of nano silicon dioxide, 2-3 parts of an antioxidant DSTP, 2-3 parts of ethylene thiourea and 25-35 parts of a modified filler. The produced cable sheath material has excellent physical performance, dimension stability, low shrinkage, strong product stretching accelerant strength, anti-tearing strength and elastic force and good oil resistance, heat resistance, burning resistance, sun light resistance, ozone resistance, acid and alkali resistance and chemical reagent resistance; and the modified filler has good dispersibility and low surface tension, so that the tensile strength and stress at definite elongation of the cable sheath material are further improved, the heat generation and compression permanent deformation are reduced, the aging speed of the cable sheath material can be slowed down, and the cable sheath material can resist acid and alkaline corrosion and is low in production cost.

Description

technical field [0001] The invention mainly relates to a cable sheathing material, in particular to a cable sheathing material with high tensile resistance. 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 she...
