摘　　要：传统烷基烯酮使用阳离子淀粉作为乳化剂和稳定剂,存在纤维上留着低、与纤维反应较慢和施胶熟化时间长等缺点。作者研究了高取代度阳离子木薯淀粉的制备工艺、AKD乳液的乳化工艺和施胶性能。结果表明,以木薯淀粉为原料和3-氯-2-羟丙基三甲基氯化铵为醚化剂制备的淀粉阳电荷密度为0.5-3.5 meq/g,取代度大于0.1的阳离子淀粉,对AKD蜡粉具有良好乳化稳定作用和纸张施胶性能。In this manuscript,a high substituted cationic starch was synthesized and then applied on the emulsification.The best performances of emulsification and sizing in papermaking were achieved at conditions：the cationic starch density of positive charge was 0.5-3.5 meqv/g,substitution was more than 0.1,viscosity was less than 1 000 mPa·s.
