Research on Rheological Behavior and Property of Addition Polymerization of Waterborne Epoxy Resin/Waterborne Amine
摘要
Abstract
The rheological properties of the waterborne epoxy resin/waterborne amine system with addition-polymerization reaction are studied by using an R/S PLUS rheometer, and the effects of waterborne amine (HF or HG), reaction temperature and time on the rheo-logical behavior are discussed. The results show that both HF and HG waterborne amines could effectively make the addition-polymerization reaction of HF or HG waterborne amine with waterborne epoxy resin take place. With increase of temperature,the viscosity decreases in the first 30 min period and then it goes up fast, the viscosity increases with prolongation of reaction time, and then it tends to be a balance viscosity value. The waterborne epoxy resin, waterborne amines, and the addition-polymerization products are all non-Newtonian fluids. The rheological behavior in the addition-polymerization reaction process changes with the changes of temperature, time and shear velocity, and it could well be described by Her-schel Bulkley and Casson rheological model equations. Thermal stabilities of the cured films are also studied with dynamic mechanical thermal analysis and thermogravity analysis.关键词
