Antireflection coating for solar glass with anti-ash function, preparation method thereof, and anti-ash high anti-reflection solar glass

Abstract

The invention relates to the technical field of glass coating coatings, in particular to an anti-reflection coating for solar glass with an anti-ash function, a preparation method thereof, and anti-ash high anti-reflection solar glass. The components of the solar glass anti-reflection coating with anti-ash function include water-based silicon dioxide resin, organic template agent, functional nano particle solution and water. Components of the functional nanoparticle solution: needle-like nano-ATO or / and carbon nanotubes, nano-NTO and water. The solar glass anti-reflection coating with anti-dust function can lift dust to reduce the contact area between the dust and the film layer, so that the dust is not easy to absorb and slip off more easily, and the anti-dust effect is better. The anti-ash and anti-reflection solar glass not only has high light transmittance, but also has anti-static super-hydrophilic function, which can strongly inhibit the adhesion of dust, thereby reducing the problem of power generation efficiency degradation caused by solar photovoltaic modules being easily stained with dust outdoors, and It can reduce the cleaning frequency of solar photovoltaic modules to reduce cleaning and maintenance costs.

Description

technical field [0001] The invention relates to the technical field of glass coating coatings, in particular to an anti-reflection coating for solar glass with an anti-ash function, a preparation method thereof, and anti-ash high anti-reflection solar glass. Background technique [0002] At present, the solar photovoltaic module market in various countries in the world is growing rapidly, especially the construction of solar power generation facilities in the Middle East and other regions with an average sunshine time of more than 12 hours. There is a lot of dust on the surface of photovoltaic modules, which affects the power generation efficiency. If it is not cleaned, the power generation can be reduced by up to 20% after the dust adheres to the surface. However, due to the lack of water in the desert area, manual or mechanical cleaning is very inconvenient, resulting in high costs for solar cell maintenance and manual cleaning. [0003] In recent years, self-cleaning coa...

[0004] However, the above three anti-fouling self-cleaning anti-reflection coatings all have defects: the super-hydrophobic anti-fouling anti-reflection coating increases the surface resistance of the glass and accumulates static electricity due to the hydrophobic component, so it is difficult to achieve the purpose of making solar glass anti-dust , and mechanical friction and weather aging will make the superhydrophobic properties of the film gradually disappear and lose the self-cleaning effect; and the photocatalytic superhydrophilic antifouling and antireflection coating due to TiO 2 The high refractive index affects the light transmittance of the glass, and it is easy to absorb stains and can only decompose organic stains such as oil stains, but cannot decompose inorganic stains such as dust and yellow sand

However, it is well known that ATO is a blue-black powder with a high refractive index. Too much addition will result in low light transmittance of the film layer and even blue light on the film layer. However, to make the film layer have an antistatic effect, nano-ATO particles must be able to contact each other to form Conductive circuit, so the amount added will affect the light transmittance and antistatic effect of the glass, which makes increasing the light transmittance and antistatic effect a contradiction
