AI Technical Summary

Benefits of technology

This patented method uses an ultra- hydrophilicity material on top of a colored paint layer during production or painting processes. By doing this, there are fewer tiny particles called waxes attached to the painted surfaces when they come into direct contact with rainwater compared to other methods like silicon oil. These small particles help keep these coatings clean from dirt and debris over time. Additionally, the use of such materials helps prevent damage caused by excessive pressure applied across them while still maintain their appearance after being exposed to harsh environments. Overall, this new technique enhances durability against contamination and makes maintenance easier than previous techniques.

Problems solved by technology

The technical problem addressed in this patented text relates to improving the quality of painted surfaces used on building outer walls while maintaining its strength against damage caused during use due to factors like weather conditions (rain) and other external influences. This includes developing better colored paints without compromising their effectiveness over time under various environments where they may come into contact with each other's environment.

Abstract

The invention relates to a super-hydrophobic stain-resistant multicolor coating and a preparation method thereof. The super-hydrophobic stain-resistant multicolor coating comprises, by weight, 10-30% of protective sol, 30-50% of dispersion phase base paint, 20-50% of continuous phase varnish. The preparation technique for super-hydrophobic surfaces is applied to the continuous phase varnish, so that the entire multicolour coating shows up lotus effect. After spraying and drying, the contact angle of the coating surface and water can reach the standards of super-hydrophobic surfaces, the multicolor coating is enabled to have low-adhesion and self-cleaning capabilities, water droplets are difficult to adhere to the surface of the coating, easily roll on the surface and slide off to take away pollutants, and self-cleaning effect is achieved. The super-hydrophobic stain-resistant multicolor coating integrates advantages of economy, attractiveness and environmental protection, meets the requirements of sustainable development and has huge market development potential.
