The invention relates to a quick dissolution and quick dispersion emulsion powder and a manufacturing method thereof. The EVA emulsion and PAA emulsion are used as main materials, and EDTA, cellulose ether or polyvinyl alcohol or polyacrylic amide, silicone emulsion, magnesium silicate, dolomite powder and triethanolamine are used as auxiliary materials, and are stirred, mixed, atomized, dried, cooled, tested and packaged. It can dissolve rapidly in water, disperse rapidly and evenly, and form latex with original liquid property. It can be made with a variety of inorganic cementitious materials, such as cement, hemihydrate gypsum and so on, which have special properties and uses, such as polymer cement dry mixed mortar, polymer plastering gypsum and other finished dry mortar. It has stable quality, easy packaging, moisture-proof, antifreeze, easy transportation, easy storage, and no breeding of bacteria or microorganisms. It is suitable for the manufacture of building exterior wall exterior insulation or exterior wall interior insulation polymer Bonding mortar, covering mortar, tile binder, elastic putty, self leveling mortar, plaster, etc.
