Abstract

The invention discloses an improved neoprene cable sheath material and a preparation method thereof. The material comprises, by weight parts, 100-120 parts of neoprene particles, 15-20 parts of magnesium silicate, 5-10 parts of petroleum ether, 20-30 parts of sodium polyacrylate, 6-12 parts of active nanometer calcium carbonate, 25-35 parts of dicumyl peroxide, 2-5 parts of white carbon black, 15-20 parts of ammonium polyphosphate, 1-2 parts of dioctyl terephthalate, 4-8 parts of barium stearate, 12-18 parts of magnesium oxide, 8-12 parts of aluminum oxide and 20-30 parts of auxiliaries. Compared with ordinary neoprene, the improved neoprene cable sheath material has higher light resistance, heat resistance, aging resistance and dielectric properties and better breakdown resistance; and the improved neoprene cable sheath material is good in water resistance and extraction resistance, low in toxicity and easy to process, has wide application prospect in the cable industry and can lower manufacture cost and has high economic benefit.

Description

technical field [0001] The invention relates to a cable raw material, more precisely, an improved neoprene cable sheath material and a preparation method thereof. Background technique [0002] Neoprene is a relatively common material used to manufacture cable sheaths. Neoprene has good physical and mechanical properties, oil resistance, heat resistance, flame resistance, sunlight resistance, ozone resistance, acid and alkali resistance, and chemical agents. It has high tensile strength, elongation and reversible crystallinity, good adhesion, aging resistance, can be used for a long time under the environment of 80-100 ℃, and has certain flame retardancy. However, neoprene also has many disadvantages, such as poor storage stability and limited use in harsher environments. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing an improved neoprene cable sheathing material and a preparation method th...
