摘　　要：纳米材料可大幅度提高环氧树脂的力学性能、抗腐蚀性能等,利用纳米材料改性环氧树脂是目前涂料领域的一个重要研究方向。利用纳米材料ZSM-5分子筛、还原氧化石墨烯(rGO)和两者相互作用(ZSM-5-rGO)对熔结环氧树脂(FBE)进行改性,并研究其对显微硬度、结合力和抗腐蚀性能的影响。结果表明:ZSM-5改性熔结环氧树脂后的显微硬度值有所提高,提升比例为44%;rGO改性熔结环氧树脂后的显微硬度值有所提高,提升比例为25.7%,其防腐性能有所提高,阻抗值从6421Ω·cm^(2)提高到75371Ω·cm^(2);ZSM-5-rGO改性熔结环氧树脂后的抗腐蚀性能好并且提高了近两倍的与铝合金基体的结合力,其中当ZSM-5与rGO配比为2∶1时,其对熔结环氧树脂的综合改性效果最佳,硬度为38.84HV,与铝合金基体的结合力为67.5N。Nanomaterials can greatly improve the mechanical properties and corrosion resistance of epoxy resin,and the use of nanomaterials to modify epoxy resin is an important research direction in the field of coatings.Fusible bonded epoxy resin(FBE)was modified by ZSM-5 molecular sieve,reduced graphene oxide(rGO)and their interaction(ZSM-5-rGO).The effects of FBE on microhardness,adhesion and corrosion resistance were studied.The results show that the microhardness of ZSM-5 modified fused epoxy resin is increased by 44%.The microhardness value of rGO modified fused epoxy resin is increased by 25.7%,and its corrosion resistance is improved from 6421Ω·cm^(2) to 75371Ω·cm^(2).ZSM-5-rGO modified fused bonded epoxy resin has good corrosion resistance and improves the binding force with aluminum alloy matrix by nearly two times.When the ratio of ZSM-5 to rGO is 2∶1,the comprehensive modification effect of ZSM-5 on fusion bonded epoxy resin is the best,the microhardness is 38.84,and the binding force with aluminum alloy matrix is 67.5 N.
