摘　　要：研究CaCl2、NaCl、KAl(SO42).12H2O复合激发剂掺量对干粉外墙腻子粘结强度、吸水率、透气性等性能的影响,对试验干粉外墙腻子水化试样进行DTA、XRD、SEM分析,确定了干粉外墙腻子中复合激发剂的最佳掺量为7%左右,并对复合激发剂对干粉外墙腻子的作用机理进行探讨。The influence of CaCl2,NaCl,KAl（SO4）2·12H2O compound activator amount on bond strength, water absorption ratio and air permeability of dry powder putty for exterior wall is studied. The hydration samples of dry powder putty for exterior wall to be tested are analyzed by DTA, XRD and SEM and it is confirmed that the optimal amount of compound activator in dry powder putty for exterior wall is 7%. The effect mechanism of compound activator in dry powder putty for exterior wall is discussed as well.
