Special caulking agent for ALC installation
The invention provides a special caulking agent for ALC installation, and relates to the technical field of building materials. The special caulking agent for ALC installation comprises Portland cement, quartz sand, redispersible latex powder, hydroxypropyl methyl cellulose ether, calcium formate, starch ether, polypropylene fiber and limestone powder. The caulking agent comprises the components in percentage by weight: 25 to 35 percent of Portland cement, 55 to 65 percent of quartz sand, 2 to 4 percent of redispersible latex powder, 0.1 to 0.5 percent of hydroxypropyl methyl cellulose ether, 0.05 to 0.2 percent of calcium formate, 0.05 to 0.2 percent of starch ether, 0.1 to 0.5 percent of polypropylene fiber and 5 to 10 percent of limestone powder. The special caulking agent for ALC installation provided by the invention is small in dry shrinkage deformation, has good crack resistance, workability and water-retaining property, has relatively high binding power with a wall material or other base materials after being hardened, so that a connecting interface is not easy to crack, the connecting stability is better, cracking of inner and outer walls can be completely prevented, and meanwhile, the bonding speed is relatively high; and the preparation process is simple, convenient and fast, and the construction efficiency can be greatly improved.
本发明提供ALC安装专用嵌缝剂，涉及建筑材料技术领域。该ALC安装专用嵌缝剂，包括硅酸盐水泥、石英砂、可再分散性乳胶粉、羟丙基甲基纤维素醚、甲酸钙、淀粉醚、聚丙烯纤维和石灰石粉，所述嵌缝剂各组分的重量百分比含量为：硅酸盐水泥25‑35％、石英砂55‑65％、可再分散性乳胶粉2‑4％、羟丙基甲基纤维素醚0.1‑0.5％、甲酸钙0.05‑0.2％、淀粉醚0.05‑0.2％、聚丙烯纤维0.1‑0.5％和石灰石粉5‑10％。本发明提供的ALC安装专用嵌缝剂干缩变形小、具有良好的抗裂性能、和易性和保水性，硬化后与墙体材料或其他基体材料具有较高的粘结力，使连接界面不易出现裂缝，连接稳定性更好，可以完全防止内外墙的开裂，同时粘接速度更快，而且制备工艺简单、方便、快捷，可以大大加快施工的效率。
