摘要
通过室外海洋大气暴晒和室内紫外线照射对环氧涂层进行了老化试验,并运用光泽、颜色、粉化率、SEM以及电化学多重动电位扫描(MCPDP)等手段测试了涂层在室外大气暴晒和室内紫外加速老化下的表面形貌和对金属保护性能的变化,初步探讨室外海洋大气暴晒和室内紫外人工老化试验的相关性。发现对于环氧涂层室内紫外人工老化降解的效果强于室外海洋大气天然老化,基于光泽测试的加速因子约为5;基于颜色和粉化率测试的加速因子都大于12。
The outdoor-exposure test and indoor-accelerated ageing test were carried out, and a series of performance evaluations such as gloss, color, the degree of chalking, SEM and MCPDP were applied to test the transformation of the surface topography and protection properties of epoxy anticorrosion paint. The correlation between indoor-accelerated ageing test and outdoor-exposure test was discussed preliminary. It indicates that the results of degradation in the indoor-accelerated ageing test are greater than those in the outdoor-exposure test, the accelerating factor according gloss is about 5 and the accelerating factors according color and the degree of chalking are above 12.
