With the implementation of residential industrialization and building energy conservation in my country, the demand for high-weather-resistant self-cleaning exterior wall coatings is increasing. Curtain wall self-cleaning painthas the following characteristics: not easy to adhere to pollution, or adhere to pollution The material energy is removed by external natural conditions such as rain and wind. Therefore, improving the stain resistance of building exterior walls has become an important indicator to measure the quality of high-performance coatings. Due to the poor scrub resistance of traditional coatings, the coating will change color and fall off after a long time, and the glass curtain wall or tile veneer will bring light pollution, increase the weight of the building, and have potential safety hazards.
1. Light intensity and light time
Nano self-cleaning coating is excited by ultraviolet light to produce super-hydrophilic properties, the hydrophilicity decays after stopping the light, and becomes hydrophilic after a period of time Sex disappears. The light intensity and light time directly affect the hydrophilicity of the coating, which in turn affects the self-cleaning performance.
2. Coating structure
The coating structure includes two aspects, one is the composition of the coating, and the other is the thickness of the coating. For example, "Glossy" is composed of a transition layer and a surface layer (self-cleaning layer). The transition layer can significantly improve the adhesion of the surface layer. The thickness of the surface coating film has a great influence on the self-cleaning performance and adhesion: the coating film is thin, the hydrophilicity of the coating film becomes worse, and the hydrophilicity decays quickly in the dark; The hydrophilic retention ability in the dark is improved; if the coating is too thick, the adhesion becomes poor.
3. Other factors
There are many other factors that affect the performance of curtain wall self-cleaning coatings, such as the crystal form, grain size and other internal factors of nano-titanium oxide, and Environmental factors during the use of self-cleaning coatings, such as PH, the type and degree of organic pollutants, etc.
