Preparation method of lightweight high-strength thermal insulation material
The invention discloses a preparation method of a lightweight high-strength thermal insulation material, which is characterized by comprising the following steps: preparing inorganic fibers; pretreating the inorganic fibers to obtain primary inorganic fibers; uniformly mixing the ceramic powder with a first binder and a second binder by using a curing agent to obtain mixed powder; the curing agents for the first binder and the second binder are solid powder; preparing a reinforcing assistant solution, and dipping the primary inorganic fiber in the reinforcing assistant solution to obtain a secondary inorganic fiber; dipping the surface of the second-grade inorganic fiber in a second binder solution to obtain a third-grade inorganic fiber; uniformly mixing the third-level inorganic fiber with the mixed powder to obtain a forming raw material; and molding the molding raw material through a mold to obtain a ceramic green body, standing, curing and demolding to obtain the lightweight high-strength thermal insulation material. The heat insulation material prepared without sintering is high in strength and light in weight in the using process, and the problems of powder falling, cracking and the like are avoided.
