摘　　要：选取不同水性建筑涂料对其耐沾污性进行研究。结果表明,涂膜的粗糙度、吸水率、硬度、静水接触角对涂膜的耐沾污性有重要影响,并简要分析了涂膜耐沾污的原理,为耐沾污水性涂料的研制开发提供科学依据。In the paper, dirt pick-up resistance performance of different water-borne architecture coatings are studied. The results indicate that the dirt pick-up resistance performance of coatings is better when coat has such properties as more smooth surface, higher hardness, lower rate of absorbing water and water contact angle near ninety degree,also the mechanism of dirt pick-up resistance performance is interpreted.
