摘要
目的考察可剥涂层在海洋大气环境下的大型工程建造中的临时防护作用。方法对来自两个厂家的可剥涂层进行了为期12周的耐候性试验,对可剥涂层在不锈钢及碳钢/环氧两种基底上的可剥离性、防护性和氟氯残留量进行了测试。结果两个厂家的涂层在外观、耐蚀性、附着力等方面的试验结果没有明显差异,涂层的剥离强度均低于0.05 kN/m,涂层剥离后不锈钢表面的氟氯离子残留量远低于15?g/dm2,试验周期内环氧漆色差变化较小。结论两个厂家的可剥涂层在光泽、硬度和剥离强度等测试方面的结果上存在差异,但对环氧漆均有着较好的防护作用,试验期内剥离性良好,且无有害化学元素残留,具有较高的工程应用价值。
Objective To investigate the temporary protective effect of strippable coatings on large engineering construction in marine atmospheric environment. Methods The weather resistance of strippable coatings from two manufactures was tested for a period of 12 weeks, including testing on strippable property, protective performance and residue of F/Cl elements of coatings on stainless steel and carbon steel/epoxy. Results Coating of two manufactures were similar in appearance, corrosion resistance and adhesive force. The peeling strength of the coatings was lower than 0.05 kN/m. The residue of F/Cl elements on the stainless steel surface was less than 15 μg/dm2 after the coatings were stripped. The color difference of epoxy paint changed a little during test period. Conclusion There are differences in the results of gloss, hardness and peel strength of strippable coatings from two manufacturers, but the epoxy paint coating has good protective and good strippable property but no residual of chemical elements. It has good engineering value.
