摘　　要：运用粒子结构设计原理,合成了核壳型自交联聚丙烯酸酯乳液,并对其成膜性能进行了考察,探讨了温度、乳化剂及胶乳结构对成膜性能的影响,研究表明,成膜温度、乳化剂、胶乳结构,包括核壳比例,交联单体比例都对成膜的性能有直接的影响。成膜的最佳条件是成膜温度在80℃,乳化剂用量为4%(质量分数),核壳比1∶1,交联单体的用量10%为(质量分数)。A cross-linking polyacrylate emulsion with core-shell structure was synthesized based on the principle of designing particle structure in this paper and the film performance was also studied. The influences of emulsifiers, temperature and latex structure on the film performance have been discussed. Study shows there are some directly influences of film for ruing temperature, emulsifiers and latex structure including core /shell ratio and cross-linking monomer ratio on the film performance. The best conditions include, the temperature is 80 ℃, emulsifier ratio is 4%, Core /shell ratio is 1：1 and Cross-linking monomer ratio is 10%.
