摘　　要：某换流站防污闪涂料涂覆后短时间内出现了憎水性快速失效的现象,其周边5公里范围内有国内某大型酒厂,属于特殊运行环境,为探究在这种特殊环境下防污闪涂料憎水性快速失效的原因,选取两组防污闪涂料放置在该换流站进行模拟试验,然后在现场和实验室对两组防污闪涂料进行憎水性、粗糙度和傅里叶红外光谱分析。结果表明:防污闪涂料的憎水性在7个月内由HC1级下降到HC4~HC5级。受周边酒厂影响,该换流站的防污闪涂料表面污秽中含有醇类、酚类等有机物,这一类有机污秽影响了小分子硅氧烷的迁移,导致防污闪涂料憎水性失效,但涂料并未出现明显老化,将涂料表面污秽擦洗后憎水性可立即恢复。The anti-pollution flashover coating in a converter station appears rapid hydrophobicity failure phenomenon in a short time after coating,and there is a large domestic winery within 5 kilometers of it,which belongs to a special operating environment.In order to analyze the reasons for the rapid hydrophobicity failure of the anti-pollution flashover coating in this special environment,two groups of anti-pollution flashover coatings were selected and placed in the converter station to conduct simulation tests,and then the hydrophobicity,roughness,and Fourier transform infrared spectroscopy of the two groups of anti-pollution flashover coatings were analyzed in the field and laboratory.The results show that the hydrophobicity of the anti-pollution flashover coating decreases from grade HC1 to grade HC4-HC5 within 7 months.Affected by the surrounding winery environment,the contamination on anti-pollution flashover coating surface in the converter station contains organic substances such as alcohols and phenols,which affects the migration of small molecular siloxanes,leading to the hydrophobicity failure of the anti-pollution flashover coating,while the coating does not show obvious ageing,and its hydrophobicity can be restored immediately after scrubbing the surface dirt.
