Abstract

The invention provides a high temperature-resistant composite inorganic binder, as well as a preparation method and an application thereof. The binder is a waterborne binder containing aluminum dihydrogen phosphate, zirconium sol and water. The binder comprises the following components in percentage by weight: 10-70% of aluminum dihydrogen phosphate, 10-80% of zirconium sol and 0-80% of water. The preparation method comprises the following steps: weighing the aluminum dihydrogen phosphate, the zirconium sol and the water according to the proportion, uniformly mixing under the conditions that the temperature is 20 DEG C-100 DEG C and the stirring speed is 200rpm-1000rpm, cooling and then obtaining the required high temperature-resistant composite inorganic binder. The binder has excellent high temperature resistance and can withstand the temperature of 2000 DEG C for a long time. The high temperature-resistant composite inorganic binder can be used for high temperature-resistant materials, ceramic coatings, fireproof materials, ceramic materials, high-temperature kiln repair materials, refractory materials, flame-retardant materials, high temperature-resistant adhesives and the like.
