The invention belongs to the technical field of air entraining agents, and particularly relates to a powdery air entraining agent for gypsum mortar and a synthesis method of the powdery air entraining agent. The powdery air entraining agent comprises the following components: a liquid air entraining agent, an anti-caking agent and an anti-sticking agent; the liquid air entraining agent comprises the following components: a foaming agent, a stabilizing agent, a dispersing and leveling agent, a wetting agent, a rheology modifier, a calcium and magnesium ion complexing agent and water, the powdery air entraining agent can effectively solve the problem of application in gypsum mortar, can show excellent foaming performance under the condition of high calcium ion concentration, is high in hard water resistance, reduces the surface tension of water, shows excellent foam stability, is fine and smooth in foam and is not easy to break, and the air entraining agent can be applied to gypsum mortar. The air entraining agent can keep the same state with initially stirred mortar for 2-3 hours when applied to gypsum mortar, keeps construction consistency, has no pungent smell, has unique wetting and dispersing capacity, can quickly disperse powder, and saves stirring time.
本发明属于引气剂的技术领域，具体涉及一种用于石膏砂浆的粉状引气剂及其合成方法。所述粉状引气剂的组分包括液体引气剂、抗结块剂和抗粘剂；所述液体引气剂的组分包括起泡剂、稳定剂、分散流平剂、润湿剂、流变改性剂、钙镁离子络合剂以及水；所述粉状引气剂能够有效解决石膏砂浆中应用的问题，该引气剂在较高钙离子浓度情况下能够表现出优异的起泡性能，抗硬水能力强，降低水的表面张力，并表现出极好的泡沫稳定性，且泡沫细腻不易破泡，应用于石膏砂浆可保持2～3小时与初始搅拌的砂浆状态相同保持施工的一致性，并且没有刺激性气味，另外该引气剂具有独特的润湿分散能力，能够快速分散粉料，节省搅拌时间。
