Nano-modified self-sealing single-component film-forming waterproof mortar
The invention discloses nano-modified self-sealing single-component film-forming waterproof mortar, and belongs to the technical field of building materials. The mortar is prepared from the followingraw materials in percentage by mass: 20-30% of ordinary Portland cement, 6-15% of sulphoaluminate cement, 10-25% of quartz sand, 40-50% of redispersible latex powder, 3-8% of nano montmorillonite, 2-6% of calcium powder, 2-4% of sodium silicate, 1-2% of polyacrylamide and 1-4% of an additive. The mortar prepared by the invention can realize rapid film formation and cracking resistance, and realizes a self-closing waterproof repair function.
本发明公开了一种纳米改性的自封闭单组份成膜防水砂浆，属于建筑材料技术领域。其由下述原料按相应质量分数制成，普通硅酸盐水泥：20‑30%、硫铝酸盐水泥：6‑15%、石英砂：10‑25%、可再分散性乳胶粉：40‑50%、纳米蒙脱土：3‑8%、钙粉:2‑6%、硅酸钠:2‑4%、聚丙烯酰胺：1‑2%、外加剂：1‑4%。本发明所制得的砂浆通过能够实现快速成膜抗开裂，并实现自闭合防水修复功能。
