A new method for the preparation of waterborne micro-nano thin layer graphite materials by expansion-dispersion-sanding was proposed and successfully applied to waterborne industrial anti-corrosive coating.The morphology， width， thickness and particle size of the prepared waterborne micro-nano thin layer graphite materials were characterized by field-emission scanning electron microscopy （FESEM）， atomic force microscopy （AFM） and nano-particle size analyzer.The corrosion resistance of the waterborne micro-nano thin layer graphite anti-corrosive coating was evaluated by water and salt water resistance tests.The results show that the thickness and width of waterborne micro-nano thin layer graphite materials are 5 nm to 27 nm and 5 μm to 50 μm respectively，and the average particle diameter is about 17 μm.The anti-corrosion property of coating prepared by waterborne micro-nano thin layer graphite materials is good， and the sample board is the same as the original board after soaking for 720 h， which far exceeds the standard requirement of 48 h.The volatile organic content （VOC）of the coating was less than 10 g/L， which is much lower than 300 g/L.
