Anti-crack mortar for painting building external wall and preparation process thereof
The invention discloses anti-crack mortar for brushing a building outer wall. The anti-crack mortar is prepared from the following components in parts by weight: 25 to 35 parts of Portland cement, 20 to 30 parts of bentonite, 10 to 15 parts of ground calcium carbonate, 1 to 3 parts of wood fiber, 5 to 10 parts of modified polymer silicon emulsion, 1 to 3 parts of organic silicon waterproof agent and 5 to 10 parts of polyurethane adhesive. According to the anti-crack mortar for brushing the building outer wall, from raw material screening and process proportioning to a processing process method, large-particle-size cement and bentonite are screened out, uniform particle sizes of the cement and the bentonite are ensured, and the compactness of all the raw materials after the anti-crack mortar is stirred is ensured in cooperation with the adhesion of the modified polymer silicon emulsion and the polyurethane adhesive; after solidification, good water seepage prevention and sun crack prevention effects are achieved.
本发明公开了一种建筑外墙涂刷用抗裂砂浆，按重量份包括以下组分：硅酸盐水泥25‑35分、膨润土20‑30份、重质碳酸钙10‑15份、木纤维1‑3份、改性聚合物硅乳液5‑10份、有机硅防水剂1‑3份、聚氨酯胶黏剂5‑10份。本发明的建筑外墙涂刷用抗裂砂浆，从原料筛选、工艺配比到加工工艺方法，筛除大粒径的水泥和膨润土，保证水泥和膨润土粒度均匀，配合改性聚合物硅乳液以及聚氨酯胶黏剂的粘粘，保证抗裂砂浆搅拌后各原料的密实度，凝固后具有较好的防渗水防干裂效果。
