The invention discloses a concrete air entraining agent with good foam stability. Characterized in that it is characterized in that it comprises, the feed additive is prepared from the following raw materials in parts by weight: 20 to 30 parts of a rosin-based hyperbranched surfactant, 5 to 10 parts of 1,4-cyclohexanedimethanol bis(3,4-epoxycyclohexaneformic acid)ester/4,4-cyclohexanedimethanol bis(3,4-epoxycyclohexaneformic acid) ester, 0.1 to 1.5 parts of phytolaccaside C, 5 to 10 parts of 2-acrylic-hexahydro-4,7-methylene-1H-indenyl ester/2-hydroxy-3-butenyl glucosinolate/vinyltrimethoxysilane/polyethylene glycol monoallyl ether copolymer, 8 to 15 parts of hyperbranched polyglycerol and 70 to 90 parts of water. The invention also discloses a preparation method of the concrete air entraining agent. The concrete air entraining agent disclosed by the invention is good in air entraining effect, good in compounding property with other additives and high in adaptability to concrete, and can effectively improve the bubble stability of fresh concrete, remarkably improve the strength of the concrete and improve the workability, durability and freezing resistance of the concrete.
本发明公开了一种稳泡性佳的混凝土引气剂，其特征在于，由以下重量份的原料制成：松香基超支化表面活性剂20‑30份、1,4‑环己烷二甲醇双(3,4‑环氧环己烷甲酸)酯/4,4'‑二氨基‑3,3'‑联苯二磺酸缩聚物5‑10份、商陆皂甙丙0.1‑1.5份、2‑丙烯酸‑六氢化‑4,7‑亚甲基‑1H‑茚基酯/2‑羟基‑3‑丁烯基硫甙/乙烯基三甲氧基硅烷/聚乙二醇单烯丙基醚共聚物5‑10份、超支化聚甘油8‑15份、水70‑90份。本发明还公开了所述混凝土引气剂的制备方法。本发明公开的混凝土引气剂引气效果佳，与其它外加剂的复合性好，与混凝土的适应性强，能有效改善新拌混凝土的气泡稳定性、显著提高混凝土强度、改善混凝土和易性、耐久性和抗冻性。
