The invention discloses a method for preparing a self-lubricating silicon carbide composite ceramic-based sealing material. The self-lubricating silicon carbide composite ceramic-based sealing material is characterized by comprising the following raw materials in parts by weight: 70-90 parts of silicon carbide, 8-12 parts of stainless steel powder, 5-7 parts of molybdenum disulfide, 2-5 parts of carbon powder, 2-3 parts of magnesium oxide, 1-2 parts of silane coupling agent KH-550, 4-5 parts of boron fibre, 2-3 parts of polyvinylidene fluoride, 1-2 parts of polyvinylpyrrolidone, 3-5 parts of sintering aids and 80-100 parts of deionized water. The self-lubrication of the ceramic is increased, the abrasion is reduced and the service life is prolonged by adding molybdenum disulfide and the carbon powder into the silicon carbide composite ceramic; the added stainless steel powder has the characteristics of low sintering temperature, low sintering aid proportion and high silicon carbide ceramic performance. The method is simple in process, moderate in cost and suitable for mass production.
