The invention provides a foaming agent mixed solution which comprises an unstable foaming agent and a foam stabilizer, and the foam stabilizer accounts for 3-50% of the total mass of the foaming agent mixed solution. The invention also provides gypsum slurry prepared by using the foaming agent mixed solution. The gypsum slurry comprises the following components in parts by mass: 100 parts of calcined gypsum, 0.2-5 parts of starch and 0.03-0.20 part of the foaming agent mixed solution. The invention also provides a gypsum board prepared from the slurry, wherein the deviation value of the pore diameter of the board core of the gypsum board does not exceed 1.2. According to the technical scheme provided by the invention, the sizes of air holes in the formed gypsum board are more uniform, and the size distribution of the air holes can be controlled to a certain extent. According to the technical scheme, the water absorption rate of the formed gypsum board is also reduced.
本发明提供一种发泡剂混合液，包括不稳定发泡剂和泡沫稳定剂，其中所述泡沫稳定剂占发泡剂混合液总质量的3‑50％。本发明还提供使用该发泡剂混合液配置的一种石膏浆料，包括以质量计的如下组分：煅烧石膏100份、淀粉0.2‑5份和所述的发泡剂混合液0.03‑0.20份。本发明又提供由该浆料的制备的石膏板，其中该石膏板的板芯的气孔直径的偏差值不超过1.2。本发明所提供的技术方案使得所形成的石膏板中的气孔尺寸更加均匀，并且可以一定程度上控制气孔的尺寸分布。本发明的技术方案还降低了所形成的石膏板的吸水率。
