Abstract
The invention discloses conductive silicon rubber which comprises the following components: silicon rubber, white carbon black, calcium carbonate, acetylene black, a structure inhibitor, liquid silicon rubber, a vulcanizing agent, aluminum oxide, vinyl-containing silane coupling agent, methyl silicone oil and zinc stearate. The silicon rubber has the advantages of high thermal conductivity, high heat resistance and low compressibility and has the heat conductivity coefficient being more than 3. Because the silicon rubber has high heat conductivity, the silicon rubber can bear higher conductive current.
