Abstract

The invention relates to the technical field of a paint, and concretely discloses a vehicle multifunctional aqueous paint and a preparation method thereof. The vehicle multifunctional aqueous paint comprises the following components in parts by weight: 15-25 parts of an aqueous polyethersulfone dispersing emulsion, 25-30 parts of an aqueous hydroxy acrylic emulsion, 5-7 parts of a curing agent, 1-5 parts of organic silicone powder, 1-5 parts of nano alumina, 0.05-0.5 parts of nano titanium dioxide, 1-8 parts of a pigment, 3-10 parts of a fire retardant, 0.05-0.5 parts of nano zinc oxide, 0.1-1part of fluorescent powder, 0.1-0.2 parts of a pH conditioning agent, 0.1-0.2 parts of an antifoaming agent, 2-5 parts of a film-forming auxiliary agent, 0.3-0.5 parts of a dispersant, 0.3-0.5 partsof a base material wetting agent, 0.5-1.0 parts of a thickening agent, 2-3 parts of a cosolvent, and 5-10 parts of deionized water. The vehicle multifunctional aqueous paint is a normal-temperature air-drying coating, has the advantages of excellent anti-corrosive property, safety and no toxicity, and convenient construction, has fluorescent effect and fireproof effect, protects the metal base material and increases the work security, and is especially suitable for special vehicles such as a large-scale outdoor work vehicle which is not suitable for baking.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a multifunctional water-based coating for vehicles and a preparation method thereof. Background technique [0002] With the sustained and high-speed development of the national economy, my country's automobile industry has developed rapidly in recent years, and my country's automobile production has leapt to the forefront of the world. However, with the rapid development of China's automobile industry, the pressure on environmental protection is also increasing. At present, the domestic automobile industry generally uses traditional solvent-based paints in automobile painting, which contain high volatile organic compounds (VOC). The coating process causes serious environmental pollution and endangers human health. Compared with traditional solvent-based coatings, water-based coatings replace organic solvents with a large amount of water, and the volatilization of organic solven...
