摘要：

以硅烷偶联剂乙烯基三乙氧基硅烷（A-151）对纳米ZnO进行表面改性，进而通过原位聚合法制备聚丙烯酸酯/纳米ZnO复合乳液，并将其应用于涂料印花中。对A-151改性前后纳米ZnO进行了红外光谱和动态光散射（DLS）分析，对复合乳液进行了DLS和透射电镜表征，研究了聚合过程中改性纳米ZnO加入方式对复合乳液的影响。结果表明与未改性纳米ZnO相比，改性纳米ZnO粒径增大；聚丙烯酸酯/纳米ZnO复合乳液粒径大小较为均一，为190～200 nm；改性纳米ZnO的加入方式对复合乳液粒径的单分散性和粒径大小影响不大，但会对其粒径分布产生影响；将改性纳米ZnO在乳液聚合的第二阶段加入时，复合乳液的凝胶率较低；复合乳液涂料印花织物的各项性能与商品涂料印花粘合剂印花织物相当。

Abstract:

Nano-ZnO was modified by silane coupling agent vinyltriethoxysilane (A-151). Polyacrylate/nano-ZnO composite emulsion was prepared by in-situ polymerization, and was used for pigment printing. Nano-ZnO before and after modification were characterized by FT-IR and DLS. The composite emulsion was characterized by DLS and TEM. Effects of nano-ZnO feeding ways on the composite emulsion were studied. Particle size of modified nano-ZnO increased compared with unmodified nano-ZnO. Composite emulsion had a relatively uniform particle size of 190~200nm. Nano-ZnO feeding ways had little effect on particle size and its monodispersity of the composite latex but affected the particle size distribution. Gel rate of the composite emulsion was lower when nano-ZnO was added in the second stage of emulsion polymerization. Performance for printed fabric using the composite latex was basically the same as the fabric printed using commercial binder.

Key words: composite emulsion, polyacrylate, nano-ZnO, pigment printing binding agentt
