Problems solved by technology

With the increase of chlorine content, the compatibility of plasticizer, low temperature resistance, compression set resistance, thermal aging performance, etc. decrease, and the water resistance is poor. When the temperature is relatively low, the material itself is relatively hard, low in elasticity and brittle. Large, low tear resistance

Embodiment 1

[0016] A stretch-resistant cable sheath insulation material, which is composed of the following raw materials in parts by weight (kg):

[0017] Neoprene CR121105, chlorinated polyethylene 12, semi-reinforcing carbon black N774 15-25, zinc oxide 3, ferrocene 2, mica powder 35, antioxidant MB 2, 2-mercaptobenzimidazole 2, horse Dioctyl maleate 8, accelerator DM 2, dibasic lead phosphite 1, nano silicon dioxide 15, 4,4'-oxobisbenzenesulfonyl hydrazide 3, antioxidant DSTP4, glass powder 4-6 , Zinc Oxide 0.8, Modified Calcium Carbonate 3, Antimony Trioxide 6, Ethylene Thiourea 6;

[0018] The preparation method of the modified calcium carbonate is as follows: mix quicklime and boiled water at a mass ratio of 1:10, digest for 5 hours, filter and remove slag through a 180 μm resonance sieve, and then further remove slag through a hydrocyclone to obtain Ca(OH) 2 Suspension, in Ca(OH) 2 Add its quality 8% chelating agent ethylenediammonium tetraacetic acid, its quality 12% magnesium...

Abstract

The invention discloses a stretch-proof cable sheath insulation material and a preparation method thereof. The stretch-proof cable sheath insulation material comprises the following raw materials in parts by weight: 90-100 parts of neoprene CR121, 18-20 parts of chlorinated polyethylene, 15-25 parts of semi-reinforcing carbon black N774, 2-3 parts of magnesium oxide, 1-2 parts of ferrocene, 30-35 parts of mica powder, MB1-2 of antiager MB, 1-2 parts of 2-thiol group benzimidazole, 5-8 parts of dioctyl maleate, 1-2 parts of promoter DM1, 0.8-1 part of dibasic lead phosphate, 12 to 18 parts of nanometer silicon dioxide, 1-3 parts of 4, 4'- oxylbisbenzenesulfonyl hydrazide, 2-4 parts of antioxidant DSTP, 4-6 parts of glass powder, 0.8-1 part of zinc oxide, 2-3 parts of modified calcium carbonate, 5-6 parts of antimony oxide and 4-6 parts of ethylene thiourea. The stretch-proof cable sheath insulation material prepared by the method has the advantages of excellent physical properties, stable size, low percentage of contraction and greatly increased tensile strength, tearing strength resistance and resilience force performance.

Description

technical field [0001] The invention mainly relates to a rubber sheath material and a preparation method thereof, in particular to a stretch-resistant cable sheath insulation material and a preparation method thereof. Background technique [0002] At present, the main materials commonly used in China as cable sheaths are neoprene, chlorosulfonated polyethylene rubber, etc., and the structural components of each material are different and their properties are also different. Chlorinated polyethylene compound is a kind of saturated chlorine-containing rubber, which partially retains the properties of polyethylene, and its elasticity and thermal stability decrease, and the substance becomes a semi-rigid material and loses its elasticity. With the increase of chlorine content, the compatibility of plasticizer, low temperature resistance, compression set resistance, thermal aging performance, etc. decrease, and the water resistance is poor. When the temperature is relatively low,...
