Gypsum plaster board and preparation method thereof
The invention discloses a gypsum plaster board. The gypsum plaster board comprises the following components in parts by weight: 100 parts of ardealite, 1-10 parts of a porous mineral material, 0.02-0.5 part of calcium oxide, 0.6-1.0 part of modified starch, 0.06-0.2 part of a foaming agent and 0.4-1.2 parts of a water reducing agent. The invention further discloses a preparation method of a gypsumplaster board. By the adoption of the technical schemes, the porous mineral material is added into the gypsum plaster board, the problem that the bonding performance of a board core and surface protection paper in the gypsum plaster board is poor is solved, the strength of the gypsum plaster board is improved, the surface density of the gypsum plaster board is reduced, and the gypsum plaster board has a certain humidifying function.
本申请公开了一种纸面石膏板，所述纸面石膏板的重量份组成包括：磷石膏100份、多孔矿物材料1～10份，氧化钙0.02～0.5份，改性淀粉0.6～1.0份，发泡剂0.06～0.2份，以及减水剂0.4～1.2份。本申请还公开了一种纸面石膏板的制备方法，采用本申请的技术方案，通过在纸面石膏板中加入多孔矿物材料，解决了纸面石膏板中的板芯与护面纸粘结性能不佳的问题，提高了纸面石膏板的强度，并降低了纸面石膏板的面密度，使其具有一定的调湿功能。
