环氧树脂的相反转乳化技术研究进展

介绍了相反转理论基础,阐述了采用相反转法制备水性环氧树脂乳液的研究进展,包括相反转乳化过程与分类、影响环氧树脂乳液稳定性的相关因素(如乳化剂种类、乳化剂含量、乳化温度和剪切速率等),提出了该领域目前存在对乳化剂要求苛刻、生产成本较高以及固化物性能有待突破等主要问题,认为今后研究方向应是进一步提高乳化剂的效率并改善固化物性能,同时满足生产成本要求,便于其工业化推广。

Research Progress in Phase Inversion Emulsification Technique of Epoxy Resin

The theoretical basis of phase inversion was briefly introduced in this paper, and the relevant research progress in the preparation of waterborne epoxy resin emulsion by phase inversion emulsification was described, including the process and classification of phase inversion emulsification, and the factors (such as the types and content of emulsifiers, the emulsifying temperature and the rate of shear, etc) influencing the stability of epoxy resin emulsion. The primal problems for this field were also presented, covering the strict demand on emulsifiers, the higher production costs and the properties of the cured resin needing to be solved. It is indicated that the development trend of waterborne epoxy resin should be focused on how to further increase the efficiency of emulsifiers and to improve the performance of cured products, meanwhile, meet the requirements of production costs so as to further industrialization.
