The invention discloses reclaimed bottom plastering gypsum for a building and a preparation method thereof. The plastering gypsum is prepared from 100-200 parts of salt gypsum, 10-20 parts of solubilizing agent and 50-60 parts of a reinforcing admixture, the solubilizing agent is prepared from DTPMP.Na7, potassium formate and zeolite powder according to a mass ratio of 1:2:1, the reinforcing admixture comprises a retarder, latex powder, a water reducing agent, Portland cement, glass beads and a diatomite, the mass of the Portland cement is 50-60% of that of the reinforcing admixture, and the plastering gypsum is good in water-retaining property and is tightly combined with a wall surface, so that peculiar smell in air is eliminated.
本发明公开一种再生建筑用底层抹灰石膏及其制备方法，包括100‑200份盐石膏、10‑20份促溶剂、50‑60份增强外加剂，所述促溶剂包括二乙烯三胺五甲叉膦酸七钠、甲酸钾、沸石粉，其中，二乙烯三胺五甲叉膦酸七钠、甲酸钾、沸石粉的质量比为1：2：1，所述增强外加剂包括缓凝剂、乳胶粉、减水剂、硅酸盐水泥、玻化微珠、硅藻土，其中，所述硅酸盐水泥的质量为所述增强外加剂的50‑60%，保水性好与墙面结合紧密，消除空气中的异味。
