In this paper, three kinds of hydroxyl component are prepared for two-component waterborne polyurethane paint, that is, acrylic dispersion, acrylic emulsion and silicone-modified acrylic emulsion. The influence of the composites of these dispersion and emulsions on polymerization process, viscosity, particle size and coagulum are investigated, infrared spectroscopy , inductance coupling plasma , transmission electron microscopy and thermogravimetric analysis are used to characterized their structure, composite, morphology and thermal stability, respectively.

本论文制备了三种用于水性双组分聚氨酯涂料的含羟基组分，即丙烯酸分散体、丙烯酸乳液和有机硅改性丙烯酸乳液，研究了这些分散体和乳液在制备过程中聚合物的羟值、酸值、玻璃化温度、乳化剂、反应温度等对聚合转化率、凝聚物含量、聚合物粘度和粒径的影响，用红外光谱、热重分析、透射电镜和感应偶合等离子技术表征了其结构、组成、形态和热稳定性。
