Preparation process of underwater polymer grouting slurry
The invention discloses a preparation process of underwater polymer grouting slurry. The preparation process comprises the following steps of weighing the following raw materials in parts by weight: 20-35 parts of modified epoxy resin, 15-30 parts of filler, 50-80 parts of Portland cement, 5-10 parts of calcium sulphoaluminate, 0.5-1.5 parts of sodium gluconate, 0.01-0.05 part of nano silicon dioxide, 0.1-0.5 part of a water reducing agent, 1-5 parts of an anti-dispersion compound and 100-150 parts of water, mixing the modified epoxy resin, the Portland cement and the filler, and stirring at the rotating speed of 60-80 r/min for 2 hours to obtain a mixture, adding calcium sulphoaluminate, sodium gluconate, nano silicon dioxide, a water reducing agent and water into a stirrer, stirring, adding the mixture prepared in the second step, continuously stirring, and adding an anti-dispersion compound to prepare underwater polymer grouting slurry, and adding polyacrylamide and hydroxypropyl guar gum as anti-dispersing agents, so that the anti-dispersing effect of the slurry when the slurry is used underwater is improved.
本发明公开一种水下高分子灌浆浆料制备工艺，称取如下重量份原料：20‑35改性环氧树脂，15‑30份填料，50‑80份硅酸盐水泥，5‑10份硫铝酸钙，0.5‑1.5份葡萄糖酸钠，0.01‑0.05份纳米二氧化硅，0.1‑0.5份减水剂，1‑5份抗分散化合物，100‑150份水；将改性环氧树脂、硅酸盐水泥和填料混合，以60‑80r/mi n的转速搅拌2h，制得混合料；将硫铝酸钙、葡萄糖酸钠、纳米二氧化硅、减水剂和水加入搅拌机中，搅拌后加入第二步制得的混合料，继续搅拌后加入抗分散化合物，制得水下高分子灌浆浆料；加入了聚丙烯酰胺和羟丙基瓜尔胶作为抗分散剂，提高该浆料在水下使用时的抗分散效果。
