Abstract

The invention discloses a water-based paint suitable for automobile hubs and a preparation method thereof, and the water-based paint comprises 10-15 parts of water-based blocked isocyanate resin, 50-60 parts of water-based acrylic acid modified epoxy resin, 25-30 parts of water-based polyurethane resin, 8-10 parts of water-soluble amino resin, 0.1-2 parts of a water-based dispersant, 0.1-2 parts of a water-based brightener, and 0.1-2 parts of a water-based defoaming agent. The water-based paint is prepared from the following components in parts by weight: 0.2-0.5 part of a water-based mixed drier, 0.1-2 parts of a water-based light stabilizer, 1-2 parts of rheology modified wax emulsion, 20-30 parts of deionized water, 3-5 parts of a coalescing agent, 0.2-0.5 part of a base material wetting agent, 3-8 parts of an adhesion promoter, 5-30 parts of pigment, 0.5-2 parts of nano fumed silica slurry and 15-20 parts of functional filler. The water-based paint suitable for the automobile hub has the advantages that the construction environment is improved, the paint is safe and environment-friendly, the product quality is ensured, the weather resistance is excellent, the stone impact resistance is good, the drying speed is high, the flexibility is good, the glossiness is high, and the use requirements are met, so that the water-based paint suitable for the automobile hub has relatively high innovativeness.

Description

technical field [0001] The invention relates to the technical field of water-based coatings for automobile wheels, in particular to a water-based coating suitable for automobile wheels and a preparation method. Background technique [0002] At present, the most common coating products on the surface of automobile wheel hubs are acrylic amino baking paint, polyester amino baking paint, etc. They are all oily products, and their general disadvantages are: toluene, xylene, ethyl acetate, butyl acetate are all used. Ester and other harmful volatile solvents. It requires high construction conditions and is extremely harmful to the environment, which greatly increases the probability of operators and users suffering from respiratory diseases, reproductive system diseases, cancer and other malignant diseases. In addition, the above-mentioned products all contain a large amount of harmful heavy metals, which will remain in the coating for a long time and seriously affect the enviro...
