| description | The invention belongs to the technical field of functional coatings, and particularly relates to a water-based aviation nano composite coating and a preparation method thereof. The coating comprises a component A and a component B. The component A is prepared from, by weight, 6%-10% of waterborne epoxy hardener, 2%-5% of modified graphene oxide dispersion liquid, 10%-15% of anti-rust pigment, 0.5%-2% of corrosion inhibitor, 30%-50% of pigment filler, 1%-3% of silane coupling agent, 10%-30% of deionized water and 3%-8% of auxiliaries. The component B is water-borne epoxy resin emulsion, the solid content is 40%-60%, and the addition amount of the component B is 30%-45% of that of the component A. The modified graphene oxide is added to optimize the performance of the waterborne epoxy primer for the aircraft skin, and the technical problems that an existing aircraft surface skin coating is poor in filamentous corrosion resistance, poor in salt fog resistance and the like in a high-damp-heat environment are solv |
