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，所述纸面石膏板按重量份计包括：由100份石膏熟料水化得到的石膏生料、5份至30份气凝胶颗粒、0.05份至1份絮凝剂、0.05份至0.2份玻璃纤维、0份至1份的减水剂、0.2份至1份促凝剂和0份至1份淀粉；任选地，所述减水剂的用量为0.3份至1份，任选地，所述淀粉的用量为0.2至1份。本身请提供的轻质保温隔热纸面石膏板同时克服了气凝胶粉末易飘浮在石膏料浆表面的问题，降低了纸面石膏板面密度，降低了板材吸水率，提高了纸面石膏板的强度和硬度以及耐火性能。
