The invention relates to the technical field of paint, in particular to a two-component high-hardness scratch-resistant waterborne matt finish paint and a preparation method thereof. The two-componenthigh-hardness scratch-resistant waterborne matt finish paint is prepared by a component A, a component B and water; the component B is waterborne polyisocyanate; the component A consists of cross-linked acrylic resin, a polysiloxane de-foaming agent, an organic silicon leveling and slipping agent, a polyether modified wetting agent, a polymeric dispersant, a silicon dioxide matting agent, dipropylene glycol methyl ether, dipropylene glycol butyl ether, a polyurethane associative rheological aid and water; through the synergistic effect of all the components, the water resistance and the chemical resistance of waterborne wood paint can be effectively improved, and the hardness, the fullness, the hand feeling and the adhesion resistance of a paint film are improved. The preparation method of the two-component high-
