Plastering mortar containing modified lithium slag gypsum
The invention is suitable for the field of building materials, and discloses plastering mortar containing modified lithium slag gypsum, the plastering mortar comprises the following components by weight: 35-50 parts of modified lithium slag gypsum, 35-55 parts of limestone powder, and 10-15 parts of a reinforcing agent; the preparation method of the modified lithium slag gypsum comprises the following steps: mixing lepidolite lithium slag powder with the specific surface area of 400-500m < 2 >/kg and desulfurized gypsum according to the weight ratio of (35-45): (55-65), adding 0.3-1% of a composite crystal modifier prepared from aluminum sulfate and sodium citrate, then adding water accounting for 40-55% of the total mass, uniformly mixing, and then carrying out autoclaving, drying, crushing, grinding and sieving. The plastering mortar is simple in raw material source and low in cost, the strength and the water resistance of the mortar can be remarkably improved, and the plastering mortar is rich in use scene and can be widely applied to indoor wall and ground decoration engineering and part of outdoor decoration engineering.
本申请适用于建筑材料领域，公开了一种含有改性锂渣石膏的抹灰砂浆，所述抹灰砂浆以重量份数计算,包括以下组分：改性锂渣石膏35‑50份、石灰石粉35‑55份、以及增强剂10‑15份；其中，所述改性锂渣石膏的制备方法包括：由比表面积为400‑500m2/kg的锂云母锂渣粉与脱硫石膏按(35‑45)：(55‑65)的重量比混合，并加入0.3‑1％硫酸铝和柠檬酸钠配置而成的复合转晶剂，随后加入总质量40％‑55％的水混合均匀后，再进行蒸压、烘干、破碎、粉磨、过筛。本申请的抹灰砂浆原材料来源简单、成本较低，能够显著提高砂浆的强度及耐水性能，且使用场景丰富，可在室内墙面、地面装饰工程及部分室外装饰工程中得到广泛应用。
