低温环境下水性外墙涂料的抗泛色性研究

Investigation on Flooding/floating Resistance of Water-borne Exterior Wall Coatings under Low-temperature Environment

重点分析了低温环境下水性外墙涂料出现泛色现象的主要因素及相应解决方案。结果显示,良好的润湿分散性、较低的颜料体积浓度、足够的防冻性能及体系触变性都有助于改善水性外墙涂料在低温环境下的泛色性问题。

This paper analyzes main factors and corresponding solutions of flooding/floating of water-based exterior wall coatings under low-temperature environment.The result shows that good humid dispersion,low pigment volume concentration,good freeze resistance and system thixotropy will contribute to improve the flooding/floating resistance of water-based exterior wall coatings under low-temperature environment.
