Abstract

The invention discloses conductive silicone rubber for cable accessories. The conductive silicone rubber comprises the following raw materials in parts by weight: 0.1 to 0.5 part of erythritol, 1 to 2 parts of polyacrylamide, 1 to 2 parts of an accelerant DBTU, 1 to 2 parts of hydroxyethyl cellulose, 2 to 3 parts of stearoyl-rac-glycerol, 1 to 2 parts of zinc dihydrogen phosphate, 15 to 25 parts of acetylene black, 1 to 2 parts of ammonium polyphosphate, 7 to 10 parts of chlorinated paraffin, 2 to 3 parts of calcium stearate, 1 to 2 parts of benzotriazole, 1 to 2 parts of dimethylacrylicacid 1,4-butylene terephthalate, 1 to 2 parts of butylene terephthalate potassium zirconium carbonate, 3 to 4 parts of a rare earth promoter, 100 to 116 parts of methyl vinyl phenyl polysiloxane rubber, 1 to 2 parts of a vulcanizing agent DCP, and 1 to 2 parts of Hexamethylcyclotrisiloxane. The rubber provided by the invention is black rubber, is high in surface strength, good in ageing resistance, high in acid and alkali corrosion resistance, good in water resistance and high and low temperature resistance, high in tensile strength, good in mechanical property, and particularly suitable for serving as conductive bushing and conductive rubber shock absorption products.

Description

Technical field [0001] The present invention mainly relates to the rubber field, in particular to a conductive silicone rubber for cable accessories. Background technique [0002] Silicone rubber has excellent heat resistance, cold resistance, dielectric properties, ozone resistance and atmospheric aging resistance. The outstanding performance of silicon rubber is its wide use temperature, which can be used at -60℃ (or lower temperature) to +250 Long-term use at ℃ (or higher temperature). However, silicone rubber has poor mechanical properties such as tensile strength and tear strength. Its physical and mechanical properties are not as good as most synthetic rubbers at room temperature. In addition to nitrile silicone and fluorosilicone rubber, general silicone rubber has oil and solvent resistance. It is not good, so silicone rubber is not suitable for common conditions. Therefore, adding various additives to silicone rubber to improve its inherent properties can improve it...
