摘　　要：通过对乳胶粒均一结构与核壳结构的比较,确定工业羊毛脂的防尘螨功能与乳胶粒结构明显关系,但是为了通过内墙耐擦洗性的国标,确定了羊毛脂用量在3%(质量分数,后同)时,核层硅烷偶联剂为0.3%,壳层硅烷偶联剂为0.2%,且核壳比为3∶7时,最终乳液对尘螨的驱避率达到60%以上,且涂膜耐擦洗通过国标。By comparing the homogeneous structure of the latex particles with the core-shell structure, it is determined that the dust mite resistant function of the industrial lanolin is obviously related to the structure of the latex particles. But in order to meet the national standard of the inner wall scrubbing resistance, it is determined that when the lanolin dosage is 3%(wt%), the silane coupling agent in the core layer is 0.3%(wt%) and the silane coupling agent in the shell layer is 0.2%(wt%) and that when the core-shell ratio is 3∶7, the dust mite repellency rate of the final emulsion is over 60% and the paint film scrubbing resistance meets the national standard.
