Preparation method of conductive silicone rubber

The invention discloses a preparation method of conductive silicone rubber, and particularly relates to the technical field of silicone rubber. The conductive silicone rubber is prepared from the following raw materials in parts by weight: 35 to 55 parts of raw silicone rubber, 5 to 8 parts of calcium carbonate, 7 to 9 parts of plasticizer, 2 to 6 parts of zirconium oxide, 6 to 10 parts of conductive filler, 2 to 4 parts of platinum complex, 2 to 4 parts of sodium sulfate, 1 to 3 parts of magnesium hydroxide, 2 to 5 parts of structure inhibitor, 6 to 9 parts of vulcanizing agent, 2 to 3 parts of methyl silicone oil and 5 to 9 parts of zinc stearate. After the plasticizer is added, the tearing strength and the elongation at break of the conductive silicone rubber are both larger than those of a common conductive silicone rubber sample of a control group, the prepared conductive silicone rubber can prevent cracks on a conductive silicone rubber product from being expanded due to stress, large plastic deformatio
