Heat-resistant inorganic phosphate adhesive was prepared using aluminum dihydrogen phosphate as main component and ultra fine MgO, ZnO and ZrO2 powder as curing agent. The adhesives could be cured under different temperature from 20℃ to 180℃ and the maximum application temperature reach 1500℃. The technical parameters are as follow: （1）Curing temperature:20-180℃ （2）Heat resistant temperature: 1500℃ （3）Shear strength:≥1.5MPa@20℃; ≥1.0MPa@500℃
