Abstract

The invention relates to a fireproof thermal insulation plate base material and a preparation method thereof. A fireproof thermal insulation plate prepared from the fireproof thermal insulation plate base material has the advantages of fireproofness, thermal insulation, and environmental protection. The fireproof thermal insulation plate base material comprises the following components, by weight, 600-750 parts of coal ash, 30-100 parts of an inorganic fiber, 70-120 parts of light aggregates, 50-100 parts of a high aluminum fiber and / or bauxite, and 6-15 parts of water glass, wherein the water glass is an aqueous Na2SiO3 solution with the concentration of 27-33g / L. The invention also relates to the preparation method of the fireproof thermal insulation plate base material. The fireproof thermal insulation plate base material is obtained by mixing the components with water according to a mass ratio of the coal ash to water of (600-750):50, and stirring to uniformly bond the components under heating conditions.
