摘　　要：介绍了水性聚偏二氟乙烯(PVDF)树脂类型、水性PVDF涂料的基础配方及成膜温度。对制备的涂料进行性能检测,并与溶剂型PVDF涂料的加速老化性能进行对比。结果表明:水性PVDF涂料可以达到溶剂型PVDF相同的超耐候性能,满足AAMA 2605—2013要求,且具有低温固化的特点。分析了施工过程中温度、湿度对水性PVDF外观性能的影响,得出施工范围以确保施工顺利。This paper describes the type of waterborne PVDF resin, the basic formulation of waterborne PVDF coatings and the film-forming temperature. The properties of the prepared coatings are investigated. Meanwhile, a comparison of accelerated weathering resistance per- formance between waterborne PVDF coatings and solvent-based ones has been carried out. The results show that the waterborne and solvent-based PVDF coatings exhibit the similar weatherability which meets the AAMA 2605--2013 Specification. Besides, the waterborne PVDF coatings can be cured at low temperature. The effects of coating temperature and humid- ity on the appearance of the PVDF coatings are also examined so as to obtain the suitable pa- rameters for good coating process.
