Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials, and in particular relates to a thermal insulation and fireproof board, a preparation method and application thereof. Background technique [0002] In the prior art, perlite insulation boards or foamed glass insulation boards are usually used as indoor or outdoor thermal insulation and fireproof boards. [0003] Among them, for perlite insulation boards, due to the low hardness of perlite particles and high porosity, the resulting perlite insulation boards have problems such as fragility and water absorption. [0004] For foamed glass insulation boards, Chinese patent application CN110183099A discloses a manufacturing method of expanded porous glass particles, in which glass raw materials, foaming agents and auxiliary materials are ground together or separately in grinding equipment; the obtained materials are mixed evenly Finally, it is prepared into granules in the ball for...
