The invention provides an efficient composite concrete air entraining agent and a preparation method thereof, and relates to the field of concrete admixtures. The efficient composite concrete air entraining agent is prepared from the following components in parts by weight: 30-40 parts of sapogenin, 30-40 parts of sapindus saponin, 10-15 parts of sodium dodecyl benzene sulfonate, 5-10 parts of coco fatty acid diethanolamide, 3-6 parts of orange essential oil, 3-5 parts of itaconic anhydride, 2-4 parts of sodium alcohol ether sulphate, 0.1-0.5 parts of sulfonated castor alcohol sodium salt, 0.1-0.5 part of carboxymethyl cellulose, 5-15 parts of nano powder, 0.01-0.1 parts of a water reducing agent, 0.01-0.1 parts of a foam stabilizer, 10-15 parts of polyethylene glycol, 2-4 parts of pentaerythritol and 130-150 parts of water. The efficient composite concrete air entraining agent can effectively improve slump, fluidity and plasticity of concrete, can reduce bleeding and segregation of the concrete, can improve homogeneity of the concrete, can reduce thermal diffusion and conduction coefficient of the concrete, can improve volume stability of the concrete and can enhance weather resistance of a field structure.
本发明提供一种高效复合型混凝土引气剂及其制备方法，涉及混凝土外加剂领域，包括以下重量份数的成分组成：皂树皂苷30‑40份、无患子皂苷30‑40份、十二烷基苯磺酸钠10‑15份、椰油酸二乙醇酰胺5‑10份、橙子精油3‑6份、衣康酸酐3‑5份、脂肪醇聚氧乙烯醚硫酸钠2‑4份、磺化的蓖麻醇钠盐0.1‑0.5份、羧甲基纤维素0.1‑0.5份、纳米粉体5‑15份、减水剂0.01‑0.1份、稳泡剂0.01‑0.1份、聚乙二醇10‑15份、季戊四醇2‑4份、水130‑150份，本发明高效复合型混凝土引气剂能有效改善混凝土坍落度、流动性和可塑性，减少混凝土泌水和离析，提高混凝土的均质性，混凝土的热扩散及传导系数降低，提高了混凝土的体积稳定性，增强了野外结构的耐候性。
