A water-based coating solution

Abstract

The invention relates to a water-based coating solution, the main active components and their mass parts are: 0.1-10 parts of special resin, 0.1-10 parts of silicone oil emulsion, 0.1-10 parts of wax emulsion, 0.1-10 parts of nano-silica sol, 0.1-10 parts of amphoteric surfactant, 50-99.5 parts of deionized water. The invention also relates to a preparation method of the aqueous coating solution. The coating solution of the present invention is water-soluble, environmentally friendly, and does not contain harmful substances to the human body; it can be quickly coated, and the operation is simple, the film is smooth, the film thickness is uniform and dense, the hydrophobic effect is excellent, and it is not easy to be stained with dust, which can make the surface of the car paint Bright, reduces the aging of the car paint, improves the protective effect of the car paint surface; the film has strong adhesion, is not easy to fall off, and has a long effective life. The coating solution of the invention is widely used, and can be used in many places such as mobile phone screens, computer screens, digital lenses, automobile rearview mirrors, automobile paints, and automobile glass.

Description

technical field [0001] The invention relates to an aqueous coating solution, belonging to the technical field of auto parts. Background technique [0002] The coating solution can form a protective film on the car paint, car glass, rearview mirror, etc., which can reduce the damage of acid and alkali substances to the car paint, reduce the aging of the car paint, improve the surface protection effect of the car paint, and reduce the Rain and other residues, easy to drive on rainy days. [0003] The current coating method is to first clean the surface of the car to remove all moisture on the surface of the car, spray the oily coating solution on the car paint windows and other positions, wait for half an hour to two hours until the solvent in the coating solution evaporates, the resin It is cured to form a polymer film in places such as car paint and windows. However, the method of using oil-based coating liquid coating not only has a long operation time, but also the whole...

AI Technical Summary

Problems solved by technology

However, the method of coating with oily coating solution not only takes a long time to operate, but also must not have dust in the whole process, otherwise the coating will be uneven, and dust will be mixed in the middle of the polymer film, which will affect the appearance. Therefore, the operation accuracy is extremely high, and the operation is slightly If you are not careful, the coating will be uneven and the surface will be uneven

In addition, this kind of polymer film has strong adsorption and is very difficult to clean. After a period of use, if you want to remove the old film on the surface, it is difficult to remove, and it is easy to leave a lot of polymer film residue on the surface of the car paint window. The car paint forms color difference, which greatly affects the appearance

And this kind of film is generally not resistant to gray

In addition, this oily coating solution contains a large amount of solvent, and operators often feel uncomfortable.

[0004] Recently, some water-based coating solutions have appeared on the market, but these water-based coating solutions have the problems of short effective time and easy to be washed away by water. Usually, the film will fall off two or three days after coating
