Composite air entraining agent for lightweight concrete and preparation method of composite air entraining agent
The invention relates to the field of concrete additives, in particular to a composite air entraining agent for lightweight concrete and a preparation method thereof.The air entraining agent is prepared from internal olefin sulfonate, a foam stabilizer, an emulsifier, a dispersing agent, micro-nano bubbles and water, and the internal olefin sulfonate is prepared from internal olefin through a sulfonation reaction and a hydrolysis neutralization reaction. The preparation method provided by the invention is simple and efficient, and the prepared air entraining agent has good air entraining performance, foaming performance and foam stabilizing performance, can greatly reduce gas-liquid interfacial tension, can introduce a large number of uniform, tiny and stable bubbles into lightweight concrete, and is especially suitable for being applied to maritime work lightweight concrete construction engineering.
本发明涉及混凝土添加剂领域，特别涉及一种轻质混凝土用复合引气剂及其制备方法，引气剂原料包括：内烯烃磺酸盐、稳泡剂、乳化剂、分散剂、微纳米气泡和水，其中所述内烯烃磺酸盐由内烯烃经磺化反应和水解中和反应制得。本发明提供的制备方法简单高效，制得的引气剂具有良好的引气性能、起泡和稳泡性能，能大幅降低气‑液界面张力，能在轻质混凝土中引入大量均匀、微小、稳定的气泡，特别适合应用于海工轻质混凝土建筑工程。
