The invention relates to the technical field of silicone rubber, and particularly relates to a ceramic fire-resistant and flame-retardant silicone rubber and a preparation method thereof. The ceramic fire-resistant and flame-retardant silicone rubber is composed of a component A and a component B in a weight ratio of 0.8-1.2: 1. The component A comprises the following raw materials in weight part: 60-140 parts of silicone rubber A, 35-45 parts of reinforcing agent, 60-100 parts of filler A, 11.4-17.2 parts of silane auxiliary agent A, 0.15-0.25 part of lubricant A, 0.1-0.3 part of flame retardant, and 0.5-1.5 parts of vulcanizing agent. The component B comprises the following raw materials in weight part: 60-140 parts of silicone rubber B, 230-290 parts of filler B, 3-6 parts of silane auxiliary agent B, and 0.2-0.4 part of lubricant B. According to the technical scheme of the invention, the ceramic fire-resistant and flame-retardant silicone rubber is good in fire-resistant and flame-retardant property, and
