Problems solved by technology

[0002] The surface coating of the car is made of organic paint. Due to its low hardness, some fine sand and other substances will inevitably remain on the rag when cleaning the surface, which will cause scratches on the car surface, which will not only affect the appearance of the car, but also shorten the service life of the car surface paint. Recently, a ceramic coating that can be used on the outer surface of automobiles has been developed, with a hardness of 9H. On the one hand, it can greatly alleviate the scratches on the outer surface of the car caused by cleaning; When it rains, the rainwater can clean the dust and dirt on the surface of the car, prolonging the interval between car washes

Abstract

The invention relates to a ceramic coating for an automobile surface as well as a preparation method and application thereof. The ceramic coating consists of the following raw materials in percentage by mass: 60-70% of siloxane, 18-21% of solvent, 2-5% of water, 0.1-1% of aid and the balance of acid. According to the ceramic coating for the automobile surface, the hardness is 9H, and thus the phenomenon of surface scratch caused by cleaning of an automobile is greatly relieved; and moreover, the coating has super-hydrophobicity as well as self-cleaning feature, the dust and dirt on the surface can be rinsed off by rainwater, and thus the interval time of each automobile washing can be prolonged. The shelf life of the one-component ceramic coating is about 3 months; the ceramic coating provided by the invention is a one-component ceramic coating; by adopting the ceramic coating to the automobile surface, the surface hardness can be enhanced to avoid scratch of automobile paint; the rain wash realizes an automobile washing effect; and the preparation method and formula are totally different from those of the existing ceramic coating.
