Lightweight heat-preservation and heat-insulation gypsum plaster board and preparation method thereof

The invention provides a lightweight heat-preservation and heat-insulation gypsum plaster board and a preparation method thereof. The gypsum plaster board is prepared from the following components in parts by weight: raw gypsum obtained by hydrating 100 parts of gypsum clinker, 5 to 30 parts of aerogel particles, 0.05 to 1 part of a flocculating agent, 0.05 to 0.2 part of glass fiber, 0 to 1 part of a water reducing agent, 0.2 to 1 part of a coagulant and 0 to 1 part of starch, optionally, the use amount of the water reducing agent is 0.3 to 1 part, and optionally, the use amount of the starch is 0.2 to 1 part. According to the light heat-preservation and heat-insulation gypsum plaster board, the problem that aerogel powder easily floats on the surface of gypsum slurry is solved, the board surface density of the gypsum plaster board is reduced, the water absorption rate of the board is reduced, and the strength, hardness and fire resistance of the gypsum plaster board are improved. 本申请提供了一种轻质保温隔热纸面石膏板及其制备方法，所
