Abstract

The invention discloses super fast-drying high-solid polyurethane paint and a preparation method thereof. The polyurethane paint comprises base stock and a curing agent, wherein the base stock comprises hydroxy acrylic resins, coloring pigments, a filler, an enhancer, an additive and a solvent. The preparation method comprises the following steps: uniformly dispersing the hydroxy acrylic resins with an antifoaming agent, a dispersing agent and a solvent, adding the coloring pigments and the filler, and shearing and dispersing at a high speed; deeply dispersing by a sanding and sealing process;and finally, adding the enhancer and a surface additive to prepare the paint. The application method comprises the following steps: mixing the base stock and the curing agent according to a ratio, uniformly stirring, blending to applicable viscosity, and applying and coating. According to the super fast-drying high-solid polyurethane paint disclosed by the invention, the problem that the conventional coating is high in emission of VOCs (Volatile Organic Compounds), slow in surface drying and long in turnover construction period is solved, the decoration requirement and corrosion prevention requirement of equipment manufacturing devices can be met, the environmental requirement can also be met, and the construction is rapid.
