Problems solved by technology

However, palm wax can only effectively achieve the effect of brightening, but the maintenance time is relatively short, and it can only maintain the effective hydrophobic function for a few months at most. After being washed by rain, it will gradually lose its luster. At present, most of the color changes are still using film. , the operation is cumbersome. Therefore, it is urgent to develop a hydrophobic crystal coating with long-lasting brightening effect and simple operation in this field, which can meet the needs of deep and effective hydrophobic protection function for many years in the application of film-forming materials other than automotive paint.

Description

technical field [0001] The invention relates to the technical field of hydrophobic coating materials specially used for car clothing and paint surfaces, and more specifically relates to a highly efficient and brightening transparent hydrophobic crystal coating composition and a preparation method. Background technique [0002] Since ancient times, it has been said that "lotus leaves will not be stained with mud, and they will not be demonized when they are washed clean." The reason is that the surface of lotus leaves has superhydrophobic and self-cleaning properties. It has been widely used in various daily necessities, such as automobiles, airplanes, spacecraft and so on. Specifically, when the contact angle between the solid surface and water is greater than 150°, the surface is superhydrophobic. [0003] Nano-titanium dioxide is an important multi-purpose inorganic functional material, widely used in the automotive industry, cosmetics, wastewater treatment, coatings and ...
