Problems solved by technology

However, some existing hydrophobic products or technologies usually do not have high optical transmittance, and are not suitable for use on solar panels and glass surfaces. Some require high temperature curing, or the preparation process is complicated and expensive, making it difficult to popularize and use.

Embodiment 1

[0029]

[0030] In the above table, C 14 h 19 f 13 o 3 Si is a perfluoropolyether containing alkoxysilane functional group.

[0031] By fully stirring and mixing the raw materials at room temperature for 2 hours, the formula sol-gel solution of the coating can be obtained, and the chemical components in the sol-gel solution can be fully hydrolyzed to form hydrophobic properties after standing for 24 hours, and the high-grade sol-gel solution of the present invention can be obtained. A hydrophobic and dustproof nano-coating composition with transmittance, because it is used as a film liquid coating. Therefore, the "hydrophobic and dustproof nano-coating composition with high transmittance" is simply referred to as "film liquid coating" below. The film liquid coating is used to cover the surface of the substrate with the commonly used coating method, which can be cured not only naturally at room temperature, but also by proper heating.

[0035]

[0036] In the above table, C 12 h 19 f 9 o 3 Si is a perfluoropolyether containing alkoxysilane functional groups.

[0037] By fully stirring and mixing the raw materials at room temperature for 4 hours, the sol-gel solution of the paint formula can be obtained, and the chemical components in the sol-gel solution are fully hydrolyzed to form hydrophobic properties after standing for 24 hours. The film liquid coating is used to cover the surface of the substrate with the commonly used coating method, which can be cured not only naturally at room temperature, but also by proper heating.

[0038] It is found from the experimental results that different concentrations of silica nanoparticles in all components have different effects on improving the light transmittance. For example, when the concentration of silica nanoparticles in the film liquid coating is 3 wt%, the light transmittance of the glass substrate will continuously increase with the increas...

Description

technical field [0001] The invention relates to the technical field of nano-coating materials, in particular to a hydrophobic and dust-proof nano-coating composition with high transmittance, a preparation method and application thereof. Background technique [0002] China's solar energy is developing rapidly, and its installed capacity ranks among the top in the world. However, the photoelectric conversion efficiency of solar panels is attenuated by sand and dust, which can reach a loss of 40% of battery efficiency. China's cars are becoming more and more popular. According to the survey and analysis of car consumers, most consumers think that blurred car windows in rainy days are the biggest safety concern. At the same time, because automobiles are often driven in some harsh environments, the vehicle glass and the vehicle body itself are easily covered by sand, dust and sludge and corroded by acid rain. These not only affect the appearance of the car, but also cause expen...
