摘要:
以钴( Co )作为金属源,均苯三甲酸( H 3 BTC )作为有机配体,采用水热法将两者配位,制备得到钴基金属有机框架化合物( Co-MOFs )。利用扫描电子显微镜( SEM )及 X 射线粉末衍射( XRD )对 Co-MOFs 的形貌及结构进行研究,证实其被成功制备。将 Co-MOFs 作为功能填料掺杂于松香基醇酸树脂中,均匀涂覆于 Q235 低碳钢电极及马口铁片上。采用极化曲线、交流阻抗技术、盐雾腐蚀试验等研究了 Co-MOFs 的添加量对漆膜性能的影响。结果表明:当 Co-MOFs 在松香基醇酸树脂清漆中的质量分数为 0.10% 时,复合涂层的腐蚀电流密度为 2.27uA/cm 2 ,防腐效率达 98.9% ,硬度达到 5 H ,盐雾试验测试结果与电化学测试一致,说明 Co-MOFs 的添加可以显著地提高涂层的防腐性能,且添加的最佳质量分数为 0.10% 。
Abstract:
: Shuttle-like cobalt based organic framework materials ( Co-MOFs ) were prepared by hydrothermal coordination of cobalt ( Co ) as metal source and H 3 BTC as organic ligand. The morphology and structure of Co-MOFs were studied by scanning electron microscope ( SEM ) and X-ray powder diffraction ( XRD ) and it was confirmed that they were successfully prepared. Co-MOFs were doped to rosin-based alkyd resin varnish as functional fillers , and coated evenly onto the carbon steel electrode and tinplate. The effect of Co-MOFs amount on the film properties was studied by polarization curve , AC impedance technology and salt spray corrosion test. The results show that the corrosion current of the composite coating is 2.27uA.cm-2, the anticorrosion efficiency is 98.9% , and the hardness is 5 H when the mass fraction of Co-MOFs in rosin-based alkyd resin varnish is 0.10% , and the salt spray test results are consistent with those of the electrochemical test , indicating that the addition of Co-MOFs can significantly improve the corrosion resistance of the coating , and the best mass fraction is 0.10%.
