Embodiment 1
[0023] A low-density conductive rubber, weighing the following raw materials: 40kg of silicone rubber, 15kg of chlorinated butyl rubber, 5kg of aluminized glass fiber, 5kg of nano-zinc oxide, 4kg of acetylene carbon black, 3kg of paraffin oil, 5kg of antimony trioxide, and rosin 4kg, vulcanizing agent 1kg, plasticizer 1kg, antioxidant 1kg and defoamer 1kg;
[0024] The above-mentioned aluminized glass fiber is obtained through the following steps: Weigh 5 kg of glass fiber and add it to 4% sodium hydroxide hot lye for 40 minutes. The temperature of the lye is 60°C. Add it to the mixed solution of potassium dichromate and 8% hydrochloric acid with a volume concentration of 2% and soak for 30 minutes. After soaking, take it out and dry it; then add the glass fiber to the SnCl with a volume concentration of 3%. 2 Soak with 4% hydrochloric acid mixture for 30 minutes, take out and dry after soaking; add glass fiber to the activation solution and soak for 20 minutes, take out and d...

Embodiment 3
[0037] A low-density conductive rubber, weighing the following raw materials: 60kg of silicone rubber, 25kg of chlorinated butyl rubber, 15kg of aluminized glass fiber, 15kg of nano-zinc oxide, 8kg of acetylene carbon black, 7kg of paraffin oil, 7kg of antimony trioxide, rosin 8kg, vulcanizing agent 5kg, plasticizer 3kg, antioxidant 3kg and defoamer 3kg;
[0038] The above-mentioned aluminized glass fiber is obtained through the following steps: Weigh 15 kg of glass fiber and add it to 8% sodium hydroxide hot lye for 50 minutes. The temperature of the lye is 70°C. Add it to the mixed solution of potassium dichromate and 12% hydrochloric acid with a volume concentration of 4% and soak for 40 minutes. After soaking, take it out and dry it; then add the glass fiber to the SnCl with a volume concentration of 5%. 2 Soak with 8% hydrochloric acid mixture for 40 minutes, take out and dry after soaking; add glass fiber to the activation solution and soak for 30 minutes, take out and d...
