DBE脱漆剂的脱漆性能研究

研究了DBE(二元酸酯及其混合物)环保型脱漆剂的腐蚀性。实验结果表明,该脱漆剂对镀锡钢板的平均腐蚀速率分别为0.121 5 g·m-2·h-1;配制好的脱漆剂敞口放置48 h后,其质量保留率分别为84%。说明该脱漆剂的腐蚀性和挥发性均较小,环保性能稳定,使用寿命较长。扫描电镜(SEM)和能谱分析(EDS)结果表明,DBE脱DBE脱漆剂的脱漆性能研究漆剂在脱漆后金属基材表明仍存在连续的磷化膜,锡元素含量与原镀锡钢板基本保持在同一水平,样板表面锡层受破坏的程度较低,不影响镀锡钢板的二次涂装和利用。

The Stripping Performance of DEB Paint Stripper

The corrosivity of a kind of environmental friendly paint stripper, DEB （dibasic acid, ester and their mixture）, was studied in this paper. The test results show that, average corrosion rate of the paint stripper to tinplate is 0.121 5 g·m^-2·h^-1; After prepared paint stripper is exposed and placed for 48 h, its quality retention rate is 84%,which can prove that the paint stripper has low corrosivity and volatility, stable environmental performance and long service life. Scanning electron microscope （SEM） and energy dispersive spectroscopy analysis （EDS） results can prove that the surface of metal substrate still exists in continuous phosphating film after paint removal, its tin element content remains at the same level with the original tinplate; So the paint stripper has smaller corrosivity on the tin layer, and doesn＇t affect the second coating and reuse of the tinplate.
