The invention discloses an epoxy anticorrosive paint, and a preparation method thereof. The epoxy anticorrosive paint comprises, by weight, 100 parts of modified epoxy resin, 80 to 120 parts of a pigment filler, 2 to 5 parts of a dispersant, 15 to 20 parts of a film forming auxiliary agent, 1 to 3 parts of a leveling agent, and 1 to 3 parts of an antifoaming agent. According to the preparation method, epoxy resin is modified without influencing the viscosity of epoxy resin, active anticorrosive functional groups are introduced into the epoxy resin through grafting, so that the epoxy resin paint is provided with excellent scrubbing resistance, shedding of the anticorrosive function groups is not easily caused, and the corrosion resistance of the epoxy resin paint can be maintained for a long term. 本发明公开了一种环氧防腐涂料及其制备方法，该环氧防腐涂料包括以下重量份的原料：改性环氧树脂100份、颜填料80-120份、分散剂2-5份、成膜助剂15-20份、流平剂1-3份、消泡剂1-3份；在不影响环氧树脂粘性的前提下，采用对环氧树脂进行改性的方式，将活性防腐官能基团通过接枝的方法引入到环氧树脂中，使得环氧树脂涂料具有良好的耐擦洗性，其耐腐蚀官能机构不易脱落，可长久的维持环氧树脂涂料的耐腐蚀性能。
