摘　　要：目的:制备Ag+-MMT改性含羟基苯丙抗菌乳液。方法:通过对含羟基苯丙抗菌乳液中Ag+-MMT的用量、热贮存稳定性,抗菌活性测试,确定最佳的加入量为3%,并通过透射电子显微镜(TEM)、红外光谱(FT-IR)等进行表征,并用SYNBIOSIS全自动微生物检测仪进行抗菌性能表征。结果:1加载银后,蒙托土结构没有发生根本性的变化;2Ag+-MMT的最佳用量为3%;3当Ag+-MMT的最佳用量为3%,抗菌性能为0级。结论:抗菌乳液有较好的乳液温度储存稳定性,较强的抗菌能力。Objective ：To prepare the styrene-acrylic-butyl antibacterial emulsions with core-shell structure which were modified by Ag^＋-MMT. Methods：The heat deposited stability and the antibacterial activity were characterized. The surface morphology and molecular structure were observed with Transmission Electron Microscope （TEM） and IR spectroscopy,Antimicrobial properties were studied by SYNBIOSIS autodetect microbe apparatus. Results：（1）MMT＇s structures had not changed atter affiliating Ag^＋ ;（2）The level of Ag^＋-MMT was 3% ;（3）When the level of Ag^＋-MMT was 3 %,antimicrobial properties was 0. Conclusion：Antibacterial emulsion has shown optimum heat deposited stability and antibacterial activity.
