采用正十八烷基硫醇对环氧/丙烯酸树脂共混物进行改性,对改性漆膜进行红外光谱、吸水率、形貌、接触角、耐蚀性和自清洁分析,结果表明:傅里叶变换红外光谱测试反映硫醇与环氧/丙烯酸共混树脂产生了交联,并形成致密和准结晶的特定排列取向;正十八烷基硫醇改性环氧/丙烯酸树脂,在m(环氧树脂)∶m(丙烯酸树脂)=4∶6时,吸水率为0.36%,其二维形貌表征发现环氧树脂与丙烯酸树脂为有序密集点状组织,三维轮廓呈现出50μm山丘状结构及10μm簇状乳突结构,其接触角为140.98°,此时耐蚀性能最好,腐蚀电流密度为5.1054×10^(-10)A/cm^(2),自清洁能力也最强。

The epoxy/acrylic resin blends were modified with n-octadecyl mercaptan,infrared spectroscopy,water absorption,morphology,contact angle,corrosion resistance and self-cleaning analysis of the modified paint films demonstrated that:fourier transform infrared spectroscopies reflect the cross-linking of thiols with epoxy/acrylic blends and the formation of a dense and quasi-crystalline specific arrangement orientation;When n-octadecyl mercaptan modified epoxy/acrylic resin at weight ratio of epoxy and acrylic resin=4:6,the water absorption of coating is 0.36%,and its two-dimensional morphological characterization reveals that the epoxy/acrylic resin is ordered and dense dot-like organization,and the three-dimensional profile shows a 50μm hill-like structure and a 10μm clustered papilla structure with a contact angle of 140.98°,at which time the corrosion resistance of coating is the best,its corrosion current density is 5.1054×10^(-10)A/cm^(2),and the self-cleaning ability is the strongest.
