Efficient water reducing agent and preparation process thereof
The invention discloses a preparation process of a high-efficiency water reducing agent. Comprising 0.4 to 0.5 part of sodium nitrite, 45 to 55 parts of lignosulfonate, 12 to 18 parts of water, 2 to 5 parts of potassium methyl silicate, 4 to 5 parts of sodium methenyl naphthalene sulfonate, 6 to 7 parts of cooked glutinous rice flour, 3 to 7 parts of water glass, 5 to 6 parts of fly ash, 3 to 5 parts of sodium tripolyphosphate, 0.5 to 0.6 part of silicon resin polyether emulsion, 9 to 11 parts of sodium gluconate, 0.03 to 0.04 part of sodium dodecyl benzene sulfonate, 0.03 to 0.04 part of triethanolamine and 9 to 11 parts of sodium sulfate. 3-4 parts of molasses, and 320-340 parts of modified naphthalene sulfonate. The overall formula is simple, the cost is low, the fluidity and impermeability of the concrete are improved through sodium nitrite, and the durability of the concrete is improved. The lignosulfonate improves the fluidity of the concrete, improves the working performance, reduces the water cement ratio, and improves the strength and durability of the concrete.
一种高效减水剂的制备工艺，包括亚硝酸钠0.4‑0.5份、木质素磺酸盐45‑55份、水12‑18份、甲基硅酸钾2‑5份、次甲基甲基萘磺酸钠4‑5份、熟糯米粉6‑7份、水玻璃3‑7份、粉煤灰5‑6份、三聚磷酸钠3‑5份、硅树脂聚醚乳液类0.5‑0.6份、葡萄糖酸钠9‑11份、十二烷基苯磺酸钠0.03‑0.04份、三乙醇胺0.03‑0.04份、硫酸钠9‑11份、糖蜜3‑4份、改性萘系磺酸盐320‑340份。本发明整体配方简单成本低，通过亚硝酸钠改善混凝土的流动性和抗渗性，提高混凝土的耐久性。通过木质素磺酸盐提高混凝土的流动性，改善工作性能，减少水灰比，提高混凝土的强度和耐久性。
