摘要
利用硅烷偶联剂KH-550对GO(氧化石墨烯)进行改性,并通过SEM、红外光谱、XRD和拉曼光谱对改性产物进行表征。将改性GO与WEP(水性环氧树脂)乳液混合,再涂抹于热镀锌钢板上,通过醋酸铅点滴试验和中性盐雾试验测其耐蚀性。研究结果表明:改性后的GO引入了新的官能团,亲水官能团减少,片层间距增大,结晶度减小;改性GO对水性环氧树脂乳液的耐蚀性有明显提高。
The graphene oxide(GO)was modified with silane coupling agent KH-550,and the modifiedproducts were characterized by SEM,infrared spectrum,XRD and Raman spectrum.The modified GO was mixedwith WEP(waterborne epoxy resin)emulsion,and then applied on the hot-dip galvanized steel sheet.The corrosionresistance was measured by lead acetate droplet test and neutral salt spray test.The research results showed that thenew functional groups were introduced into the modified GO,the hydrophilic functional groups were reduced,thelamellar spacing was increased,and the degree of crystallinity was reduced.The corrosion resistance of waterborneepoxy resin emulsion was improved obviously by the modified GO.
