摘　　要：运用可聚合乳化剂制备涂料印花黏合剂,研究乳化剂及其质量分数对单体转化率、聚合凝聚率、胶膜溶失率、胶膜力学性能及涂料印花色牢度的影响。结果表明,可聚合乳化剂与传统乳化剂复合,可以改善其聚合稳定性。键合在胶粒表面的可聚合乳化剂,可以明显降低胶膜溶失率,提升胶膜力学性能,提高涂料印花色牢度。可聚合复合乳化剂质量分数为6%时,乳液聚合具有较高的单体转化率和较低的聚合凝聚率,胶膜具有较低的溶失率,较高的断裂功和良好的涂料印花色牢度。可聚合复合乳化剂可作为制备涂料印花黏合剂的理想无APEO乳化剂。A pigment printing binder was prepared with polymerizable emulsifier.The influences of emulsifier and the mass fraction on the monomer conversion rate,polymerization coagulation rate,dissolve-loss rate and mechanical properties of latex film,and color fastness of the pigment printing binder were studied.It was found that compounding the polymerizable emulsifier with traditional emulsifier can improve the polymerization stability.The bonding of polymerizable emulsifier to the latex particle surface can reduce the dissolve-loss rate of latex film,and improve the mechanical properties of latex film and color fastness of the pigment printed fabric.Especially when the mass fraction of polymerizable compound emulsifier was 6%,the emulsion polymerization exhibited higher monomer conversion rate and lower polymerization coagulation rate,the latex film presented lower dissolve-loss rate and higher fracture work,and the pigment printed fabric had excellent color fastness.It is considered that polymerizable compound emulsifier is an ideal option for preparation of non-APEO emulsifier for pigment printing binder.
