Concrete antifreezing agent and preparation method thereof
The invention discloses a concrete antifreezing agent and a preparation method thereof. The concrete anti-freezing agent is prepared from the following components: 30 to 38 parts of urea, 3 to 8 parts of sodium acetate, 3 to 10 parts of polyethylene glycol butyl ether or trimethyl nonanol polyvinyl ether, 10 to 15 parts of polycarboxylic acid high-performance water reducing agent, 2 to 3 parts of sulfonated acetone-formaldehyde condensate, 2 to 5 parts of polyacrylamide, 2 to 5 parts of diethanolisopropanolamine, 3 to 5 parts of sodium gluconate and 1 to 3 parts of calcium stearate. 2-3 parts of sodium abietate and water. According to the invention, the freezing point of liquid in a concrete mixture can be obviously reduced, ice crystals are refined, and the frost resistance of concrete is improved. In addition, the anti-freezing agent can also obviously improve the gas content, can obviously promote concrete hydration, accelerates concrete coagulation and further improves the compressive strength.
本发明公开了一种混凝土防冻剂及其制备方法，所述混凝土防冻剂包括如下组分：尿素30‑38份、乙酸钠3‑8份、聚乙二醇丁醚或三甲基壬醇聚乙烯醚3‑10份、聚羧酸高性能减水剂10‑15份、磺化丙酮‑甲醛缩合物2‑3份、聚丙烯酰胺2‑5份、二乙醇单异丙醇胺2‑5份、葡萄糖酸钠3‑5份、硬脂酸钙1‑3份、松香酸钠2‑3份和水。本发明能显著降低混凝土拌合物中液体的冰点，细化冰晶，提高混凝土的抗冻性能。此外该抗冻剂还可以显著提高含气量，可以明显促进混凝土水合作用，加速混凝土凝结以及进一步提高抗压强度。
