摘要
目的研究添加和未添加防霉剂的A04-60氨基烘干磁漆的抗霉性能。方法对添加和未添加防霉剂的A04-60氨基烘干磁漆样件进行霉菌试验,并对菌种进行分离、纯化和鉴定。采用扫描电子显微镜(SEM)分析涂层老化、变质特征。结果分离并鉴定出侵蚀菌种,获得了霉菌对A04-60氨基烘干磁漆涂层的侵蚀特征。结论添加防霉剂显著提高了A04-60氨基烘干磁漆的抗霉性能,黑曲霉是侵蚀A04-60氨基烘干磁漆涂层的主要菌种,并造成涂层疏松,且侵蚀孔洞结构随霉菌试验时间的增长而变得粗大。
Objective To study the anti-mildew capability of A04-60 amino baking enamel with or without addition of fungicide. Methods Fungus test was conducted for the samples of A04-60 amino baking enamel with or without addition of fungicide, and separation, purification and identification of the strains were performed. Scanning electron microscopy （SEM） observation method was used to analyze the erosion and deterioration characteristics of the coating. Results The erosion strains were isolated and identified, and the erosion characteristics of fungi on the coating was obtained. Conclusion Addition of fungicide could significantly improve the anti-mildew capability of A04-60 amino baking enamel. Aspergillus niger was the main erosion strain of the coating, which caused the coating porosity, and the erosion pore structure became thicker with the prolongation of the fungus test time.
