Self-repairing composite macromolecular self-adhesive film waterproof roll and preparation method thereof
The invention discloses a self-repairing composite high-molecular self-adhesive film waterproof roll which sequentially comprises a high-molecular sheet layer, a self-adhesive layer and an isolation sand layer from bottom to top, the isolation sand layer is prepared from the following raw materials in parts by weight: 20 to 30 parts of ordinary Portland cement or white cement, 5 to 10 parts of silica fume powder, 0.1 to 0.3 part of triethanolamine, 0.5 to 1.0 part of nano silicon dioxide, 40 to 60 parts of quartz powder, 0.3 to 0.6 part of silane coupling agent, 0.2 to 0.3 part of carboxylic acid water reducing agent and 20 to 30 parts of water. The self-repairing composite high-molecular self-adhesive film waterproof roll has the beneficial effects that the isolation sand layer contained in the self-repairing composite high-molecular self-adhesive film waterproof roll contains a large amount of hydroxyl (-OH), and the hydroxyl (-OH) can easily react with multivalent ions such as cement hydration products Ca < 2 + > and Al < 3 + > to generate a crystalline material. After the concrete is poured, active substances such as nano silicon dioxide and silica fume in the isolation sand migrate and diffuse into capillary pores of the concrete under the siphon action of water and partially react; when the concrete is dry, the active substance is in a dormant state, can be activated when meeting water, and reacts to generate crystals to repair concrete cracks.
本发明公开了一种自修复复合型高分子自粘胶膜防水卷材，由下至上依次包括高分子片材层、自粘胶层、隔离砂层，所述隔离砂层包括下述重量份的原料：普通硅酸盐水泥或白水泥20‑30份、硅灰粉5‑10份、三乙醇胺0.1‑0.3份、纳米二氧化硅0.5‑1.0份、石英粉40‑60份、硅烷偶联剂0.3‑0.6份、羧酸减水剂0.2‑0.3份、水20‑30份。本发明的有益效果为：本发明所述一种自修复复合型高分子自粘胶膜防水卷材所含隔离砂层中含有大量羟基(‑OH)，容易与水泥水化产物Ca2+、Al3+等多价离子反应生成结晶材料。当混凝土浇筑后，隔离砂中纳米二氧化硅、硅灰分等活性物质借助水的虹吸作用向混凝土毛细孔隙中迁移、扩散并且部分反应；当混凝土干燥时，活性物质处于休眠状态，遇水会被激活，反应生成结晶体，修补混凝土裂缝。
