Abstract

See full text

In certain examples, this invention provides an inorganic composite binder with high-temperature resistance comprising 5-12% of aluminum hydroxide, 15-35% of phosphoric acid, 0.1-1% of rare earth oxide, 5-20% of silica sol, 1-15% of polyaluminum phosphate, 1-5% of borax, based on the total weight of said binder, and the rest being water, and a method for producing the same. The binder of the example can be used in temporary protective coating layer such as the high temperature coating and the high temperature antioxidation coating layer during the heat treatment of the metal workpiece, can make it possible to form an antioxidation coating layer immediately upon directly spraying the coating onto the substrate surface of the metal at high temperature of 400-1000° C., and can continuously keep its good bonding property under the high temperature environment in the heating furnace, thereby it is helpful to reduce the oxidation loss of the metal material in the heat treatment, and improve the surface quality of the metal material; also, the binder of the invention is usable in patching material for high temperature kiln or refractory material to enhance the material strength and lengthen its service life.
