The invention discloses a preparation method of an environment-friendly novel waterproof plugging grouting material. The novel waterproof plugging grouting material is prepared from the following components in parts by weight: 30-45 parts of Portland cement, 60-70 parts of silica sand, 8-12 parts of active chemical substances and 14-32 parts of cyanogen setting slurry, the preparation method of the novel waterproof and leak-stopping grouting material comprises the following steps: preparing a grouting material; the preparation method comprises the following steps: S1, preparing an active chemical substance, namely mixing and stirring a certain amount of free ionized calcium, magnesium hydroxide, aluminum hydroxide and a nonionic surfactant, and selecting 14-32 parts of free ionized calcium, magnesium hydroxide and the nonionic surfactant for later use; the cyanogen setting slurry is added into the raw materials, the isocyanate-terminated group of a cyanogen setting prepolymer in the cyanogen setting slurry reacts with water to release gas CO2, a degassing reaction is carried out, and meanwhile, a chain extension reaction is also carried out, so that bubbles are eliminated in the grouting process of the waterproof leaking stoppage grouting material, the curing effect in the grouting process is ensured, and the waterproof leaking stoppage grouting material has the advantages that the waterproof leaking stoppage grouting material has good waterproof and leaking stoppage effects. Therefore, the connection firmness and the service life of the grouting part are ensured.
本发明公开了一种环保型新型防水堵漏灌浆材料制备方法，新型防水堵漏灌浆材料按重量份计由以下成分组成：硅酸盐水泥30‑45份、硅砂60‑70份、活性化学物质8‑12份和氰凝浆液14‑32份；所述新型防水堵漏灌浆材料的制备方法包括以下步骤；步骤S1：活性化学物质的制备，选取一定量的游离子钙与氢氧化镁、氢氧化铝和非离子型表面活性剂进行混合搅拌，并选取14‑32份备用。本发明通过在原料中添加了氰凝浆液，氰凝浆液中的氰凝预聚体的端异氰酸基与水反应放出气体CO2，进行脱气反应，与此同时，也进行了扩链反应，不仅保证了防水堵漏灌浆材料在灌浆的过程中，消除气泡，同时保证了灌浆古中的固化效果，从而保证了灌浆部位连接的牢固性和使用寿命。
