Polyester acrylate hybrid dispersions prepared mixing water

The present invention provides a method of preparing the polyester polyol acrylate heteroaryl mixed aqueous dispersion, belongs to the chemical industry, including the preparation of the polyester polyols, polyester-acrylic hybrid prepared blended polyol resin, neutralized to salts and to ionized water dispersion. The polymerization method employed to prepare the polyester simultaneously mixed polyester polyol resin and the acrylate monomer mixture was added dropwise a mixed-acrylic hybrid resins, effectively formed between the two segments interpenetrating network resin structure, improved two compatible resin; in addition, the polymerization solution was added dropwise by fractional carboxylic acid monomer, an acid value of the resin is reduced, reducing the amount of amine neutralizing agent, improved water resistance of the coating, the resulting water higher stability of the dispersion. The dispersion can be prepared by mixing an isocyanate and an amino resin curing agent or curing agents or two-component coatings and one-component aqueous resin binder of high performance, a good cured coating film density, high gloss, especially the solvent excellent type.
