Description

technical field [0001] The invention relates to the technical field of cement material preparation, in particular to a single-component high-temperature resistant and fire-resistant inorganic adhesive, in particular to a single-component high-temperature resistant and fire-resistant inorganic adhesive used for sealing and repairing high-temperature equipment. Background technique [0002] When high-temperature equipment such as automobile exhaust pipes, high-temperature pipes, and boilers need to be sealed, filled, potted, repaired and bonded, it is often because the heat-resistant temperature of the existing ordinary adhesive is not enough, and the fire resistance is not good. The phenomenon of combustion and volatilization cannot play a role in sealing; when repairing high-temperature furnaces, it is often impossible to seal due to poor viscosity of the mortar, poor anti-peeling performance, poor anti-stability performance, and high temperature cracking. There are also som...
