以硅烷偶联剂作为交联剂,制备了具有核交联结构的聚丙烯酸酯多元醇乳液(Si-PHA),并用FTIR、TEM、粒径分布仪对乳液进行结构表征。FTIR、TEM和粒径分布仪均证实,硅烷偶联剂在聚合过程中发生了部分水解、缩合反应,得到具有核交联结构的Si-PHA。Si-PHA乳胶粒为表面具有凹陷结构的近似球体,且粒径呈单分散分布。Si-PHA乳胶粒内的硅氧烷在贮存期间会继续发生水解、缩合反应,乳胶粒粒径进一步变小。 A polyacrylate polyol emulsion (Si-PHA) with a core-crosslinked structure was prepared by using a silane coupling agent as a crosslinking agent. The emulsion was characterized by FTIR, TEM and particle size distribution analyzer. FTIR, TEM and particle size distribution analyzer both confirmed that the silane coupling agent partially hydrolyzed and condensed during the polymerization process to obtain Si-PHA with nuclear cross-linked structure. Si-PHA latex particles as the surface has a concave structure of the approximate sphere, and the particle size was monodisperse distribution. Si-PHA latex particles within the siloxane will continue during storage hydrolysis, condensation reaction, latex particles further smaller particle size.
