The solvent-free coating with the low-viscosity has the positive effects of freeness from volatilizable solvent, capability of eliminating coating pin holes, high adhesion, high permeation resistance, high wear resistance, high corrosion resistance, smooth coating surface after being sprayed, good anti-drag and wear-resisting effects, and popularization and application prospects.

The invention discloses an aqueous dispersion coating prepared by adopting a PET waste material and soya oil acid. The aqueous dispersion coating is prepared from the following ingredients in percentage by weight: 30-60% of aqueous dispersion prepared by adopting a PET waste material and soya oil acid, 5-30% of a water-based color paste, 0-10% of an amine neutralizer, 0-20% of a cosolvent, 30-60% of distilled water and 5-20% of other addition agents. The aqueous dispersion coating is prepared through the following steps: mixing the ingredients; adopting a medium speed blunger for stirring. The aqueous dispersion coating is mainly used for surface coating of woodware, can enhance storage stability of a water-borne alkyd coating, and has the advantages of being quick-drying, high in hardness and excellent in decoration effect; the aqueous dispersion coating is adopted to replace a solvent-based alkyd resin coating, so that pollution of a solvent to the atmospheric environment is reduced.

The invention provides a water-based paint and preparation and application methods thereof. The water-based paint is mainly prepared from a specific amount of water-based polyurethane resin, water-based organosilicon-modified polyurethane dispersion, organic silicon resin, water-based fluorocarbon resin, water-based organosilicon-modified acrylate, polyethylene wax slurry and water-based acrylic resin.
