Description

Technical Field

[0001] The present invention relates to the technical field of coating layers, and particularly to a hydrophobic and wear-resistant coating for glass. Background Art

[0002] Automobile side window glass is an indispensable part of an automobile. When it rains, rainwater will adhere to the glass surface, causing light refraction, making it difficult for the driver to clearly observe the vehicles coming from the side and rear, and affecting driving safety. To solve this problem, there are currently mainly two technical paths: hydrophobic modification or hydrophilic modification of the glass surface. The hydrophilic modification solution is to reduce the contact angle of water droplets so that the water droplets form a uniform water film. A typical method is to generate nano-silica by hydrolysis of tetraethyl orthosilicate to form a hydrophilic coating on the glass surface. This hydrophilic coating is easily contaminated by dust, dirt, etc. in the environment during actual use and loses its hydrophilic effect; the hydrophobic modification solution is to coat a hydrophobic coating on the glass. By increasing the contact angle of water droplets, it is difficult for the water droplets to adhere and they slide off quickly, improving the clarity of the automobile glass during rainy driving.

[0003] The existing hydrophobic coatings endow their surfaces with excellent superhydrophobic properties due to their multi-level micro-nano structures and hydrophobic waxy materials. However, when these hydrophobic coatings are formed on glass, they will affect the light transmittance of the glass. In addition, the low surface energy of the hydrophobic coating surface results in poor adhesion to the glass substrate and easy detachment. The multi-level rough structure is damaged by various external force impacts, friction, or liquid corrosion, not only greatly reducing the hydrophobic performance, but also possibly causing adhesion to water.

[0004] To solve the above problems, the Chinese invention patent with the authorization announcement number CN112210272B discloses a wear-resistant superhydrophobic composite material and its preparation method. By combining a micron-sized particle composed of a multi-stage nano-particle combination with strong mutual particle interaction and a stable structure with an epoxy-based adhesive, a composite superhydrophobic coating with a micro / nano-level surface structure is prepared. This method improves the mechanical stability of the superhydrophobic coating to a certain extent. However, the preparation process of the terminal amino hyperbranched polysiloxane and ACNTB-SiO2-coupling agent particles used in the coating is complex, requires high reaction conditions, is not easy to prepare in batches, and uses multi-walled carbon-oriented carbon nanotube bundles as one of the main fillers, resulting in a high cost and having limitations in actual use. The light transmittance and light aging resistance of the prepared coating still need to be further improved.

[0005] It can be seen that developing a hydrophobic and wear-resistant coating for glass with high light transmittance, good hydrophobicity, excellent wear resistance and light aging resistance meets the market demand, has broad market value and application prospects, and is of great significance for promoting the development of the hydrophobic and wear-resistant coating field.
