The invention discloses reclaimed surface plastering gypsum for a building and a preparation method thereof. The plastering gypsum comprises the following components in parts by mass: 250-300 parts ofsalt gypsum, 10-20 parts of a solubilizing agent and 10-30 parts of a reinforcing admixture, and the solubilizing agent comprises DTPMP.Na7, potassium formate and zeolite powder according to a mass ratio of 1:2:1, and the reinforcing admixture comprises a retarder, a water-retaining agent, latex powder, desulfurized gypsum, zinc powder and hydrated iron oxide gel. The invention further disclosesa preparation method of the plastering gypsum, so that salt gypsum is recycled, and the plastering gypsum is high in operability and good in waterproof and moisture-proof performance.
本发明公开一种再生建筑用面层抹灰石膏及其制备方法，包括质量份数如下的组分：250‑300份盐石膏、10‑20份促溶剂、10‑30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、沸石粉的质量比可以为1：2：1，所述增强外加剂包括缓凝剂、保水剂、乳胶粉、脱硫石膏、锌粉、水合氧化铁凝胶，还公开了其制备方法，实现盐石膏的再利用，可操作性强，防水防潮性能好。
