High-foam-stability and low-sensitivity concrete air entraining agent and preparation method thereof
The invention provides a high-foam-stability and low-sensitivity concrete air entraining agent and a preparation method thereof, and belongs to the technical field of concrete admixture preparation, the high-foam-stability and low-sensitivity concrete air entraining agent comprises the following raw material components in percentage by mass: 20-40% of a gemini surfactant, 2-4% of a viscosity modifier, 2-8% of a foam stabilizer, 1-3% of a synergist and 45-75% of water. According to the high-foam-stability and low-sensitivity concrete air entraining agent disclosed by the invention, the asymmetric gemini surfactant and multiple functional components have a synergistic effect, so the foaming and foam stabilizing capabilities are remarkably improved; compared with a conventional air entraining agent, the high-foam-stability and low-sensitivity concrete air entraining agent has the advantages of low mixing amount, high foam stability, high adaptability to hard water and the like, and can meet the use requirements in severe environments such as high cold and low air pressure.
本发明提供一种高稳泡、低敏感混凝土引气剂及制备方法，属于混凝土外加剂制备技术领域，其原料组分及组分占原料总量的质量百分比分别为：双子型表面活性剂20～40％，粘度调节剂2～4％，泡沫稳定剂2～8％，增效剂1～3％，水45～75％；本发明的高稳泡、低敏感混凝土引气剂以不对称双子型表面活性剂和多种功能组分协同作用，起泡和稳泡能力显著提升，相比于常规引气剂具有掺量低、稳泡性高、对硬水适应性高等优点，可以满足高寒低气压等严酷环境下的使用需求。
