摘要： 通过一锅法在硅烷偶联剂改性的玄武岩鳞片（ MBS）表面原位生长沸石咪唑骨架材料（ZIF-8）得到 MBS@ZIF-8新型复合填料，随后与环氧树脂（ EP）复合构建了一种新型抗菌耐腐蚀环氧涂层（ MBS@ZIF-8/EP）。通过扫描电子显微镜（ SEM）、 X射线衍射仪（XRD）和傅立叶变换红外光谱仪（FT-IR）对 MBS@ZIF-8的形貌、成分进行表征，通过平板计数法探究了 MBS@ZIF-8对大肠杆菌和金黄色葡萄球菌的抑菌性能，通过电化学阻抗谱（ EIS）探究 MBS@ZIF-8对环氧涂层耐腐蚀性的影响。结果表明：制备的 MBS@ZIF-8复合填料表现出优异的抗菌性能，对大肠杆菌和金黄色葡萄球菌的抑菌效率均可达 90%以上；同时 MBS@ZIF-8能有效提高环氧涂层的耐腐蚀性和机械性能。其中， MBS@ZIF-8/EP涂层的 |Z|_{0. 01 Hz}相较于 EP涂层提升了 3个数量级，硬度为 6H。在 1 080 h的中性盐雾试验后，该涂层表面无明显腐蚀现象，表明 MBS@ZIF-8/EP涂层具有优异的机械性能与防腐抗菌性能。

Abstract: In this study，the Zeolite imidazolate framework-8（ZIF-8）was in-situ grown on the surface of silane coupling agent modified basalt scale（BS）by one-pot synthesis to obtain the new composite filler（MBS@ZIF-8），which was then used to construct a new type ofanti-bacterial and corrosion-resistant epoxy coating（MBS@ZIF-8/EP）. The morphology andcomposition of MBS@ZIF-8 was characterized by scanning electron microscope（SEM），X-ray diffractometer（XRD）and Fourier transform infrared spectroscopy（FT-IR）. The bacteriostatic properties against E. coli and S. aureus of MBS@ZIF-8 were investigated by plate countingmethod，and its effect on the corrosion resistance of epoxy coating was investigated byelectrochemical impedance spectroscopy（EIS）. The results showed that the preparedMBS@ZIF-8 composite filler had excellent antibacterial performance，with the antibacterial efficiency of E. coli and S. aureus more than 90%. Meanwhile the MBS@ZIF-8 couldeffectively increase the corrosion resistance and mechanical properties of the epoxy coating.Compared with the pure epoxy coating，the |Z|_{0. 01 Hz} of MBS@ZIF-8/EP was upgraded by 3 orders of magnitude，and the hardness reached 6H. No obvious corrosion phenomenon wasobserved on the MBS@ZIF-8/EP coating surface after 1 080 h of neutral salt spray，showingexcellent mechanical and anti-corrosion properties.

Key words: ZIF-8, basalt scale, epoxy resin coating, synergistic anti-corrosion effect, antibacterial
