Abstract The graphene oxide (GO) was prepared by the Hummers method, and then modified with ethylenediamine to obtain aminated graphene oxide (NGO). The anti-corrosion and fire-proof waterborne epoxy composite coating was prepared by adding pentaerythritol phosphate (PEPA), aluminum triphosphate (ATP) and NGO to the waterborne epoxy resin, and then applied on the surface of steel sheet by air spraying method. The structure and morphology of GO and NGO were characterized by IR, XRD and SEM. The performance in anti-resistance and fire-proof resistance of the prepared coatings with different color ratios (pigment/resin ratio: P/B) was further investigated by means of electrochemical test, salt spray test, fire resistance test, residual carbon morphology analysis and thermogravimetric analysis. The results show that the composite coating with the P/B ratio of 0.2 presents the best comprehensive performance in anti-resistance and fire-proof.
