The invention discloses a ceramic bonding agent, a ceramic bonding agent abrasive disk and a preparation method of the ceramic bonding agent abrasive disk. The ceramic bonding agent comprises, by weight, 20-60 parts of SiO2, 10-30 parts of B2O3, 5-20 parts of Al2O3, 3-6 parts of Li2O, 6-15 parts of Bi2O3, 5-20 parts of P2O5, 0.2-1.5 parts of TiO2 and 0.5-2 parts of Sb2O5. A grinding layer of the ceramic bonding agent abrasive disk is composed of, by volume percentage, 5-50% of cubic boron nitride (CBN) or diamond, 5-40% of white corundum, 5-30% of the ceramic bonding agent and 3-5% of whiskers. The boron, aluminum and phosphorus silicate ceramic bonding agent disclosed by the invention has the good liquidity and tensile strength, can well infiltrate and control a grinding material, and has a good cutting capacity; the whiskers are added into the ceramic bonding agent, the strength of the ceramic bonding agent is increased, the grinding durability is improved, the hardness of the bonding agent is reduced, self-sharpening performance of a grinding tool is improved, and accordingly the durability of a grinding wheel is improved and the service life of the grinding wheel is prolonged. Efficient grinding on various steel materials is achieved through the synergistic effect of the CBN, the white corundum, the silicon carbide, wollastonite and the graphite, and high durability is achieved.
