The PUA emulsion having super strong ability of covering the matting powder and realizing high extinction and high permeability includes a polyester diol, diisocyanate, a methacrylate monomer, a chain extender, dibutyltin dilaurate, an initiator, a buffer agent, an emulsifier, triethylamine, an ammonia aqueous solution and water. The PUA emulsion not only has high hardness, but also has better water and solvent resistance, and more important, the PUA emulsion has low costs and can bring higher economic benefits; the water-based polyurethane dispersion mainly plays the role of a high-efficiency dispersant and can efficiently disperse an inorganic matting agent, so that a paint film can still maintain high permeability under the condition of high extinction; and the preparation method of the PUA emulsion having super strong ability of covering the matting powder and realizing high extinction and high permeability has the characteristics of a simple process, low production costs, and suitability for large-scale production.
