Epoxy resin-organic bentonite-metal oxide composite material and preparation method thereof

The invention discloses an epoxy resin-organic bentonite-metal oxide composite material. The epoxy resin-organic bentonite-metal oxide composite material is formed by dispersing and compounding nano particles formed by mixing organic bentonite and ZnO-ZrO2 metal oxides in an epoxy resin matrix material; the preparation method of the composite material comprises the following steps of: uniformly dispersing nano particles of organic bentonite and ZnO-ZrO2 metal oxides into epoxy resin liquid by a mechanical mixing method; finally obtaining a novel epoxy resin-organic bentonite-ZnO-Zr2O2 metal oxide composite material by a series of stirring, adding and processing. In a preparation process, a leveling agent and a defoaming agent are not used, and therefore, preparation cost of the material is further lowered. An anti-corrosive coating material disclosed by the invention has good corrosion resistance and can be applied in marine engineering architectures and structural steel or a reinforcing steel bar in a relati
