Anti-crack mortar for external wall thermal insulation
The invention relates to the technical field of external wall mortar, in particular to anti-crack mortar for external wall thermal insulation. Comprising the following raw materials in parts by weight: 40-60 parts of Portland cement, 20-40 parts of gravel, 10-20 parts of modified glass beads, 10-20 parts of basalt fibers, 20-30 parts of lightweight aggregate, 20-30 parts of resin, 0.05-0.1 part of an air entraining agent and 2-3 parts of tributyl phosphate. Portland cement is used as a main material, resin is used as an auxiliary gel material, gravel and lightweight aggregate are used as a framework, and modified vitrified micro bubbles and basalt fibers are doped, so that the dispersity and cohesiveness in the mortar are good, the mortar is not prone to agglomeration, the drying shrinkage degree of the mortar in the curing process is reduced, and the cracking condition is reduced; after the mortar is cured, the impact resistance, the weather resistance, the durability and the breaking strength are effectively enhanced, falling caused by long-time use of the mortar due to the gravity of the mortar can be reduced, long-time use of the external wall mortar is facilitated, and the external wall mortar has good heat preservation performance and crack resistance.
本发明涉及外墙砂浆技术领域，具体涉及一种用于外墙保温的抗裂砂浆；包括以下原料为硅酸盐水泥40～60份、砂石20～40份、改性玻化微珠10～20份、玄武岩纤维10～20份、轻质骨料20～30份、树脂20～30份、引气剂0.05～0.1份、磷酸三丁酯2～3份；以硅酸盐水泥为主要、树脂为辅助凝胶材料，以砂石和轻质骨料为骨架，改性玻化微珠、玄武岩纤维的掺杂，砂浆中分散性和粘结性较好，砂浆不易团聚，砂浆在固化过程中减少干燥收缩程度，减少开裂情况，砂浆固化后有效增强耐冲击、耐候性和耐久性、抗折强度，能够减少因砂浆本身的重力长时间使用造成的脱落，有利于外墙砂浆的长时间使用，具有良好的保温性能和抗裂性能。
