摘要
采用专用高分子表面活性剂研制了系列萜烯树脂乳液。研究结果表明,修正后的计算亲水亲油平衡值(HLB值)的方法可用于高分子表面活性剂中单体质量比的设计,萜烯树脂的HLB值被定为 13。乳化中应添加助溶剂来降低萜烯树脂的熔化温度和时间。高分子表面活性剂的结构极大地影响萜烯树脂的乳化结果,本研究中高分子表面活性剂苯乙烯-聚丙烯酰胺-单体 3(质量比 1∶0. 6∶0. 2)用量为 10%时能将萜烯树脂T-90、T-100和T-110乳化成稳定的乳液。
Series terpene-resin emulsions were prepared using polymeric surfactants designed for the emulsions.The results showed that hydrophile-lypophile balance(HLB) values could be used as the design basis to determine monomer ratios in the polymeric surfactants,HLB value of terpene-resins in this study was 13.Solvent was used to decrease melting temperature and time of the resin during emulsification.The structures and amounts of the polymeric surfactants influenced greatly the emulsification results.The polymeric surfactant with mass ratio of styrene,acrylamide and monomer 3 at mass ratio 1∶0.6∶0.2 was a good emulsifier for the terpene resins(T-90,T-100,T-110).The amount of the surfactant used in the emulsification was 10%.
