摘　　要：通过研究可再分散乳胶粉的不同掺量对于粉外墙腻子粘结强度等性能的影响,对试验干粉外墙腻子水化试样进行SEM测试,确定了干粉外墙腻子中可再分散乳胶粉的最佳掺量为1．5%～2．5%,揭示了可再分散乳胶粉对干粉外墙腻子的作用机理。Study was carried out for effects of different additions of redispersible latex powder on properties of powdered putty for exterior wall such as bonding strength.. SEM was made of the hydration samples for powdered putty for exterior wall, The optimum addition of 1,5%-2.5% redispersible latex powder was determined for use in powdered putty for exterior wall and mechanism of redispersible latex powder on powdered putty for exterior wall was revealed.
