High-strength gypsum board and preparation method thereof
The invention discloses a high-strength gypsum board and a preparation method thereof. The high-strength gypsum board is prepared from the following components: calcined gypsum powder, modified starch, water, zeolite and a water reducing agent. The preparation method of the high-strength gypsum board comprises the following steps: (1) uniformly mixing and stirring the water, the modified starch and the water reducing agent, (2) uniformly mixing and stirring the calcined gypsum and the zeolite, (3) uniformly stirring the mixtures obtained in the steps (1) and (2), and (4) molding and drying themixtures obtained in the step (3) until the weight is constant, thereby obtaining the high-strength gypsum board. According to the invention, the starch is added by a wet method, so that the starch gypsum board is more uniformly mixed during preparation, and good bonding performance of the gypsum board can be ensured; zeolite is good in chemical stability, exchangeability, acid and alkali resistance and high temperature resistance can also improve moisture absorption and enhancing performance of the gypsum board, zeolite is added through a dry method, batch production of factories is more convenient, zeolite and starch are added together through a wet method, and zeolite is easier to precipitate in a pipe and block the pipe.
本发明公开了一种高强石膏板及其制备方法，所述高强石膏板由下列组分组成，熟石膏粉、改性淀粉、水、沸石以及减水剂。所述高强石膏板的制备方法包括下列步骤：1)将水和改性淀粉以及减水剂混合搅拌均匀，2)将熟石膏和沸石混合搅拌，3)将步骤1)和2)得到的混合物搅拌均匀，4)将步骤3)得到的混合物成型干燥处理，直至干燥至恒重，即得高强石膏板。本发明中淀粉的湿法添加使淀粉石膏板的制备中混合更加均匀，可保证石膏板的粘接性能良好；沸石的化学稳定性好，其交换性及耐酸碱、耐高温的特性也可提高石膏板的吸湿、增强性能，沸石采取干法添加对于工厂批量生产更加便捷，且与淀粉一同湿法添加，更易在管内沉淀，堵塞管道。
