The invention relates to a waterborne epoxy self-leveling anti-scratch floor paint and a preparation process thereof. The waterborne epoxy self-leveling anti-scratch floor paint is characterized by being prepared from a component A and a component B, wherein the component A comprises, by mass, 80 parts of waterborne epoxy resin and 20 parts of an active diluent; and the component B comprises, by mass, 20-25 parts of a waterborne epoxy curing agent, 22-33 parts of deionized water, 0.2-0.6 part of a wetting and dispersing agent RS610, 0.3-0.5 part of a defoaming agent DF681F, 0.5-1 part of an anti-scratch aid, 0.2-0.4 part of an alkali swelling thickener A401, 4-6 parts of titanium dioxide, 2-3 parts of phthalocyanine blue BGS, 1-1.5 parts of strontium chrome yellow 801, 10-15 parts of lightcalcium carbonate, 20-25 parts of precipitated barium sulfate, 2-3 parts of an anti-scratch agent and 10-15 parts of ultrafine talcum powder. The paint provided by the invention utilizes water as a dispersion medium, does not contain volatile organic solvents such as toluene and xylene, saves a lot of resources, eliminates the possibility of fire hazards during construction, reduces pollution tothe atmosphere, and enhances working environment conditions. A coating formed by the paint has good adhesion; and a paint film formed by the paint has greatly improved scratch resistance and good adhesion to most substrates.
