摘　　要：混凝土结构中大量使用涂料进行防腐蚀和劣化修复,准确掌握涂料的各项性能对于监控其使用效果十分重要。为了能够快速检验和测试混凝土涂料性能的优劣,根据日本土木协会和日本道路协会标准,检测了分别以氟树脂、聚氨酯和环氧为面漆的涂层配套体系的耐碱性、附着强度、耐老化能力和对裂缝的追随性。对各种涂层的性能进行了对比和分析。结果表明,各类涂层均对混凝土底材具有优异的附着能力;耐碱性能具有较大差异;氟树脂涂层具有更好的耐老化能力和更优的裂缝追随性,对混凝土结构的防护效果最佳。In order to realize fast and accurate detect and test of the quality of coatings for concrete, the alkali-resistance, adhesion, weather resistance and crack-fitting ability of various kinds of reinforced concrete coatings with fluorine resin,polyurethane and epoxy resin as the primers were examined according to Japan Road Association criterion.And the performance of various types of coatings was compared.Results indicate thatall kinds of tested coatings have excellent adhesion to the concrete, but they show much different alkali-resistance.Specifically, fluorine resin-based coating had the best weather resistance and fitting ability to crack, showing the best protective efficiency for the concrete.
