摘要:
为了改善水性醇酸树脂乳液耐水¸干燥¸硬度等性能,首先制备丙烯酸预聚物,然后进行酯化反应合成丙烯酸改性醇酸树脂(丙改醇树脂),用相反转法制备乳液结果表明:树脂合成过程中适宜的工艺条件为引发剂用量(质量分数)为2%,链终止剂的用量(质量分数)为1.5%,混合单体的滴加时间为4h,预聚物的保温时间为3h,酯化反应温度为210ª,酯化时间为150min适宜的乳化工艺条件制备的丙改醇树脂乳液的性能均有所改善,如干燥时间缩短¸硬度增强¸粒径减小等。
Abstract:
In order to improve the performance of alkyd resin in water resistance, drying and hardness, acrylic prepolymer was used to modify the alkyd resin, and the emulsion was prepared by using emulsion phase inversion method. The synthesis process was investigated. The results showed that the proper resin synthesis condition was that the amount of initiator was 2%; the amount of chain terminator was 1.5%; mixed monomer dropping time was 4 h; prepolymer holding time was 3 h; esterification reaction temperature was 210 ℃; and esterification time was 150 min. The properties of propanol alcohol emulsion prepared by suitable emulsification process conditions were improved, such as shortened drying time, enhanced hardness and reduced particle size.
