The invention provides a building gypsum product and a preparation method thereof, and the preparation method comprises the following steps: mixing building gypsum powder with water, then carrying out pouring molding, and after setting and hardening, carrying out mold removal; and putting the product subjected to form removal into alcohol for curing, and then drying to obtain the building gypsum product. According to the method disclosed by the invention, after the building gypsum is formed, the alcohol is used as a curing agent, the residual adhering water in the gypsum product is sucked out by utilizing the water absorption characteristic of the alcohol, and the residual adhering water is continuously hydrated in the process to generate dihydrate gypsum crystals to fill pores in the product and increase the compactness, so that the strength of the gypsum product is improved; the curing process is easy and convenient to operate, the curing agent can be recycled, the production cost is not increased in the curing process, and the application range is wide.
本发明提供了一种建筑石膏制品及其制备方法,所述制备方法包括以下步骤:将建筑石膏粉与水混合后浇筑成型,待凝结硬化后进行拆模;将拆模后的制品置于醇类中养护,再经干燥得到建筑石膏制品。本发明所述方法在建筑石膏成型后以醇类为养护剂,利用醇类的吸水特性,将石膏制品中的剩余附着水吸出,并在此过程中继续水化生成二水石膏晶体,填充制品中的孔隙,增加密实度,从而提高石膏制品的强度;所述养护工艺操作简便,养护剂可循环使用,养护过程中不增加生产成本,应用范围广。
