The invention relates to the field of wet electric precipitation, in particular to a flame-retardant and conductive silicone rubber anode film for wet electric precipitation and a preparation method of the flame-retardant and conductive silicone rubber anode film. The flame-retardant and conductive silicone rubber anode film for wet electrostatic precipitation provided by the invention comprises the following components in parts by weight: 45-60% of silicone rubber, 10-25% of a flame retardant, 20-35% of a conductive material, 0.2-1.5% of a coupling agent, 0.2-1.5% of a crosslinking aid, 0.4-2.0% of a structured control agent and 0.2-1.5% of a vulcanizing agent. The flame retardant grade of the flame-retardant and conductive silicone rubber anode film for wet electrostatic precipitation can reach UL94V-0 grade, the surface resistivity is lower than 1000 ohm, and meanwhile, due to the super-hydrophobic (ash) property, the static contact angle is larger than or equal to 90 degrees, the thickness is smaller than
