People's Daily: A new preparation technology for nano-self-cleaning coatings has been introduced.

Reporters from the Chinese Academy of Sciences Hefei Institute of Material Science was informed that: Recently, the Institute of Technology and Biology Wu Zhengyan team using new technology means to develop nano-self-cleaning
coating
, the technical raw material cost of up to 5000 yuan / ton, experiments show that the paint surface dust stains can be reduced by more than 50%, saving more than 50% labor costs.
green production mode is the main trend of the current development of coatings, there is an urgent need to develop low-cost, high efficiency, strong stability, environment-friendly self-cleaning coating preparation technology through scientific and technological innovation, to promote The supply side of China's coating industry structural reform and transformation and upgrading. Wu Zhengyan team used physical modification of natural nano-clay as the main material, after organic modification, the preparation of ultra-hydrophobic nanocomposite materials, the material as an additive in accordance with a certain proportion added to the coating, preparation from the cleaning coating. The technology can also regulate the coating surface potential, effectively reduce the coating surface to dust electrostatic adsorption capacity, significantly enhance the coating anti-dust performance.
