摘　　要：目的 了解水基胶固化过程中水分散失的规律。方法 建立基于纸胶体系及烘干模式的固化时间测定方法,提出水基胶“有效固化”的概念,利用皮尔模型对水基胶干燥曲线进行拟合,并研究5种水基胶在不同干燥温度下的干燥曲线。结果 结果表明,皮尔模型可以较好地拟合水基胶的干燥曲线。固化率在80%~90%存在一个拐点,具体位置与干燥温度有关。当固化率达到70%时纸胶体系已基本完成黏合,对应的有效固化时间相对于完全固化时间可缩短74.60%~83.70%。在干燥温度一定时,不同水基胶的固化时间有一定的差异,其差异性主要表现在低温干燥区域。结论 综上所述,干燥温度一定时,低玻璃化转变温度、低粒径、高固含量、高黏度的水基胶的固化时间更短。The work aims to understand the law of water loss during the curing process of water-based adhesives.The curing time measurement method based on the paper adhesive system and drying mode was established,and the"effective curing"concept of water-based adhesives was put forward.The drying curve of water-based adhesives was fitted with the Peel model,and the drying curves of five water-based adhesives at different drying temperature were studied.The results showed that the Peel model could better fit the drying curve of water-based adhesives.There was an inflection point in the curing rate between 80%and 90%,and the specific position was related to the drying temperature.When the curing rate reached 70%,the paper adhesive system basically completed the bonding,and the corresponding effective curing time could be shortened by 74.60%~83.70%compared with the complete curing time.At constant drying temperature,the cur-ing time of different water-based adhesives was different,and the difference was mainly reflected in the low-temperature drying area.In summary,at constant drying temperature,the curing time of water-based adhesives with low glass transi-tion temperature,small particle size,high solid content,and high viscosity is shorter.
