摘要(Abstract)：

以天然驱蚊植物——艾叶提取物为芯材,采用复相乳液法制备驱蚊微胶囊。讨论了初乳中乳化剂用量、芯材与二氯甲烷体积比、壁材用量、保护性胶体浓度等对微胶囊粒径的影响,获得了最佳制备工艺。将粒径最小的微胶囊与黏合剂以一定比例混合后整理到涤纶织物上,并对驱蚊效果进行测试和分析。结果表明:最佳制备工艺为初乳中乳化剂体积分数为6%,芯材与二氯甲烷体积比为1∶6,壁材质量分数为4%,保护性胶体质量分数为2%;制得的微胶囊最小平均粒径为2.78μm;整理到涤纶织物上的驱蚊效果显著,蚊虫驱避率达到70%。
With the extraction of natural anti-mosquito folium artemisia argyi for core material,it can prepare anti-mosquito microcapsule by adopting composite phases emulsion method.Through discussing the influence of emulsifier dosage,internal aqueous phase to dichloromethane,dosage of wall material and concentration of protective colloid on particle size,the optimum preparation process is received.The polyester fabric is finished by capsules and adhesive with a certain proportion for anti-mosquito testing.The results show that emulsifier dosage is 6 %,internal aqueous phase to dichloromethane is 1:6,dosage of wall material is 4 %,concentration of protective colloid is 2 %,the minimum particle size of capsule is 2.78 μm,and the repellent rate reaches 70 %.This shows remarkable anti-mosquito effect.
