My countrys self-cleaning coatings market is vast and technology is mature

Architectural exterior paint can beautify the environment and living room, but due to the poor washability of traditional paint, the coating will not last for a long time. Discoloration and shedding occur, and the glass curtain wall or tile veneer will bring light pollution, increase the weight of the building, and have potential safety hazards. And with the urban environmental pollution is intensifying, dust pollution, gas pollution is particularly serious. Building facades, especially high-rise buildings, are being increasingly eroded. The ideal exterior wall protection and decoration materials in the 21st century should have excellent water resistance, permeability to water vapor, anti-ultraviolet light and self-cleaning functions, and can maintain a clean and beautiful appearance for a long time. How to make the exterior wall of the building last for a long time? At present, the curtain wall self-cleaning paint will create a cleaner, healthier and more beautiful living environment for people. The field of curtain wall self-cleaning coatings already has mature technical strength: in Shanghai World Expo alone, the exterior walls of the Japan Pavilion and the exterior walls of the China Aviation Pavilion adopt ETFE self-cleaning film technology and PVC self-cleaning film technology, both of which have well demonstrated the curtain wall. Advantages of self-cleaning coatings.

According to the regulations of the city appearance and environmental sanitation industry associations in major domestic cities (Beijing, Shanghai, Guangzhou, etc.), the exterior walls of buildings are made of glass. Or fluorocarbon curtain wall, it must be cleaned every 3 to 6 months; it is stone or veneer brick, it must be cleaned once a year. Some people have done such statistics and also calculated: For example, the curtain wall area of 10,000 square meters needs about 20 tons of water to be cleaned twice a year. At present, there are more than 400 high-rise buildings over 100 meters in Shanghai alone. According to the definition of the Ministry of Public Security, more than ten stories are high-rise buildings. The number of high-rise buildings in Shanghai should be more than 10,000. Nano self-cleaning coatings, the amount of water saved every year is also amazing. It can be said that only from the perspective of the self-cleaning paint market for architectural self-curtain walls, the economic benefits cannot be underestimated.

“Curtain Wall Self-Cleaning Paint” is not a new term. As early as 2000, Germany launched a silicone resin exterior wall paint with the function of "lotus leaf self-cleaning", and the dust on the wall can achieve self-cleaning effect through rainwater; in 2001, Japan also launched a light Catalytic self-cleaning exterior wall paint can achieve self-cleaning effect by decomposing the oil stain on the wall. In recent years, many domestic scientific research institutions have launched products such as self-cleaning coatings with their own characteristics, which not only improves the scrub resistance of exterior wall coatings from more than 1,000 times to more than 10,000 times, but also prolongs the aging time by more than 2 times. , and coating the surface of glass and ceramic tiles with a nano-thin layer to make self-cleaning glass and ceramic tiles, which can make oil stains, bacteria, etc. adhering to the surface become gas or gas under the irradiation of light and the catalysis of nano-materials. Substances that are easily wiped off.
