Novel inorganic waterproof plugging material and application thereof
The invention discloses a novel inorganic waterproof plugging material and application thereof. The inorganic waterproof plugging material is prepared from, by mass, 89%-92% of a cementing material, 1.0%-2.5% of sodium silicate, 0.15%-0.25% of a thickening agent, 0.4%-0.6% of a waterproof agent and 2%-4% of redispersible latex powder, with the balance being silica fume, wherein the waterproof agent is one or two selected from calcium stearate and sodium stearate. Through reasonable collocation and combination of various raw materials, a rapid and violent hydration reaction occurs, and settingand hardening are completed within a few minutes, so various requirements on the quick-setting inorganic waterproof plugging material are met, and the strength and the impermeability of the material are excellent and far beyond the standard.
本发明公开了一种新型的无机防水堵漏材料及其应用，无机防水堵漏材料按质量分数包括胶凝材料89%‑92%、硅酸钠1.0%‑2.5%、增稠剂0.15%‑0.25%、防水剂0.4%‑0.6%、可再分散乳胶粉2%‑4%、硅灰余量，所述防水剂为硬脂酸钙和硬脂酸钠中的一种或两种，本发明通过多种原材料的合理搭配组合，产生迅速且剧烈的水化反应，在短短几分钟内完成凝结硬化，满足对速凝型无机防水堵漏材料的各项要求，表现出远超标准的出色的强度和抗渗能力。
