Description

technical field [0001] The invention relates to the technical field of building thermal insulation boards, in particular to an inorganic fireproof thermal insulation board for building exterior walls and a preparation method thereof. Background technique [0002] The external thermal insulation system of the building exterior wall is a non-load-bearing thermal insulation structural assembly composed of thermal insulation boards, protective layers, and fixing materials and suitable for installing the external surface of the external wall. At present, the commonly used insulation boards include inorganic insulation boards, organic insulation boards and composite insulation boards. Inorganic fireproof insulation boards are low in cost, do not produce harmful substances during use, and are favored by the market due to their high flame retardant effect. [0003] Inorganic fireproof insulation board is mainly made of inorganic materials, adding admixture and water to make slurry, ...
