在乳液成膜过程中,毛细管力起辅助作用,本文对这些年来的理论模型进行综述。由于水面的消退形成的力是主要的驱动力,毛细管液体桥力作用较差,环境相对湿度(RH)对这些力无影响。利用光透射技术,研究了温度和湿度对无表面活性剂丁基丙烯酸酯乳液的成膜的影响。在稍低于Tg的温度下可以成功成膜,若假设水是一种溶剂,RH仅轻微促进涂膜的形成。本文对助溶剂在促进涂膜形成中的浓度影响进行了证实。 In the process of emulsion film formation, capillary force plays an auxiliary role. In this paper, the theoretical models of these years are reviewed. Due to the force formed by the subsidence of the water surface is the main driving force, the capillary force of the capillary liquid is poor, and the relative humidity (RH) has no effect on these forces. The effects of temperature and humidity on the film formation of the surfactant-free butyl acrylate emulsion were studied using light transmission techniques. Film formation can be successful at temperatures slightly below Tg, and if only water is assumed to be a solvent, RH only slightly promotes film formation. In this paper, the influence of co-solvent on the concentration in the formation of coating film was confirmed.
