摘要
利用改性后石墨烯与环氧树脂等原料通过一步法成功制备出系列石墨烯与环氧树脂复合材料,采用扫描电子显微镜(SEM)、电化学阻抗谱和极化曲线等表征其防腐性能.着重考察石墨烯含量对于环氧树脂防腐底漆性能的影响.结果表明,石墨烯/环氧树脂复合材料呈现块状结构,相比于单体石墨烯与环氧树脂,该防腐底漆能显著提高钢结构的防腐效果.防腐涂层的厚度与其防腐相关性能呈正相关.优化后的防腐底漆材料的耐盐雾实验时间可达2 000 h以上,研究结果可为机械工程材料的防腐蚀研究提供参考.
Abstract
A series of graphene and epoxy resin composites were successfully prepared by one-step method from modified graphene and epoxy resin,and their anticorrosion properties were characterized by scanning electron microscope(SEM),electrochemical impedance spectroscopy and polarization curve.In this paper,the influence of graphene content on the properties of epoxy anticorrosive primer was investigated.The results show that the graphene/epoxy resin composite presents a block structure.Compared with the monomer graphene and epoxy resin,the anti-corrosion primer can significantly improve the anti-corrosion effect of steel structures.The thickness of anti-corrosion coating is positively related to its anti-corrosion related properties.The salt spray test time of the optimized anti-corrosion primer material can reach more than 2 000 h,and the research results can provide reference for the anti-corrosion research of mechanical engineering materials.
