Problems solved by technology

[0002] With the rapid development of China's economy, cars, once a luxury, have officially entered thousands of households. Now almost every household has at least one car. Every car owner basically cherishes his car and often decorates himself. There are many kinds of paints currently used for car decoration, but most of them contain organic toxic solvents such as toluene and xylene, which greatly affects the working environment of paint coating. At the same time, these toxic solvents Volatilization will do great harm to the health of car owners and their families, and will also cause certain environmental pollution.
[0003] In the prior art, the Chinese patented water-based automobile axle paint with the application number CN201610989233.8 uses water as the solvent and water-based epoxy resin as the main body, which is non-toxic and environmentally friendly. It can be applied to the decoration and protection of various automobile axles; however, with long-term exposure to ultraviolet rays, its hardness will be greatly reduced

Abstract

The invention discloses water-based automobile decorative paint. Water-based polyurethane resin and water are used as main materials of the whole paint, and the paint does not contain any organic solvent and is environmentally friendly, free of toxicity and conductive to the health of the human body; at the same time, thickeners, dispersants, defoaming agents, leveling agents, film forming agents,solubilizers, buffering agents, wetting agents, hardening agents and color paste are also added. Six substances including bis-(2,2,6,6-tetramethyl-4-piperidyl)sebacate, 4-benzoyl-5-methyl-2-phenyl-2H-pyrazole-3 (4H)-ketone, zirconia diisopropylbis-(2,2,6,6-tetramethyl-3,5-heptanedionate), 3-methacryloxypropylmethyldimethoxysilane, 3-methylamino-1,2-propanediol and triethanolamine are adopted as the hardening agents. Under the combined action of these substances, the hardness of the finally prepared water-based automotive decorative paint is up to 3H and remains basically unchanged under long-term irradiation of ultraviolet rays at the same time.
