| Abstract: | Viewed from technology for industrializing production of the resin, the influence of dispersing equipment, dispersing temperature, maturing time, and distilling temperature on the storage stability of aqueous polyurethane dispersion and its paint product is explored. By investigating on the formulation technology and formula ingredients of waterborne polyurethane coatings, the effects of dispersing speed and time, matting agents and thickeners of the formula ingredients of coatings on storage stability of the coatings and paint film properties are analyzed. The production technology to produce waterborne polyurethane coatings with remarkable storage stability and the optimal method for the formulation technology as well as the formula ingredients are obtained. |
