摘　　要：选用4种最常用的混凝土涂料配套方案,通过比较涂料的耐老化性能和耐老化性实验前后的裂缝追随性能,研究了涂料耐老化性能和裂缝追随性的关系.结果表明,涂料的耐老化性能是裂缝追随性的重要影响因素,氟树脂面涂的耐老化性能最高且其涂装体系追随性在老化试验后得到良好的保持.In this paper,four kinds of the most commonly used concrete coating systems are chosen for a comparison between their aging properties and pursuit performance for concrete cracks before and after aging treatment, then the effect of aging on pursuit performance for concrete cracks of the coatings was outlined. The results showed that aging property is one of the most important factor related with its pursuit performance, among the four coatings studied,the fluoro-top-coating possesses the best aging property and pursuit performance ,hence, this painting system was durable.

关 键 词：混凝土涂料 耐老化性能 裂缝追随性
