The invention belongs to the technical field of building materials, and provides anti-cracking thin plastering mortar and a preparation method thereof. The anti-cracking thin plastering mortar is prepared from the following raw materials in parts by weight: 38 to 42 parts of cement, 52 to 58 parts of quartz sand, 12 to 18 parts of ground calcium carbonate, 12 to 18 parts of ash calcium powder, 8 to 13 parts of oxidized carbon powder, 1 to 3 parts of redispersible latex powder, 0.2 to 0.5 part of silane modified polyurethane adhesive, 0.2 to 0.5 part of modified polypropylene fiber and 0.05 to 0.1 part of polypropylene fiber. The preparation method comprises the following steps: adding water into the cement, the quartz sand, the ground calcium carbonate, the ash calcium powder, the oxidized carbon powder, the redispersible latex powder, the silane modified polyurethane adhesive, the modified polypropylene fiber and the polypropylene fiber, and stirring and mixing. The anti-cracking thin plastering mortar has the advantages of excellent anti-foaming and anti-cracking effects, good cohesiveness with the wall surface, good quality stability and long service life; the preparation method is easy to realize industrial large-scale production.
本发明属于建筑材料技术领域，提供了一种防开裂薄抹灰砂浆及其制备方法。该防开裂薄抹灰砂浆，其原料按重量份数计包括：水泥38‑42份，石英砂52‑58份，重质碳酸钙12‑18份，灰钙粉12‑18份，氧化炭粉8‑13份，可再分散乳胶粉1‑3份，硅烷改性聚氨酯粘合剂0.2‑0.5份，改性聚丙烯纤维0.2‑0.5份，聚丙烯纤维0.05‑0.1份。该制备方法包括：将水泥、石英砂、重质碳酸钙、灰钙粉、氧化炭粉、可再分散乳胶粉、硅烷改性聚氨酯粘合剂、改性聚丙烯纤维和聚丙烯纤维加水搅拌混合即可。该防开裂薄抹灰砂浆具有优异的抗起泡开裂效果，与墙面粘结性好，质量稳定性好，使用寿命长；该制备方法易于实现工业化规模生产。
