Abstract

The invention discloses a hardening film for protecting a photovoltaic glass anti-reflection layer. The hardening film is obtained after coating the surface of the photovoltaic glass anti-reflection layer with hardening liquid and carrying out ultraviolet curing. The thickness of the hardening film coating ranges from 2 micrometers to 5 micrometers, and the hardening liquid is obtained after modified acrylate, photoinitiator, infrared reflection filler, a flattening agent and a solvent are evenly mixed according to the mass ratio of 100:(5-10):(0.1-0.5):(0.1-1):(10-30). Damage of severe external factors such as wind sand and hail to the glass anti-reflection layer can be effectively blocked, a proper amount of infrared reflection filler is added into the hardening liquid, part of pyrogenic infrared rays causing heating of an assembly can be reflected, the temperature of the inner layer is reduced, and good application prospects are achieved in the photovoltaic field, the photothermal field, the building field, the greenhouse field, the decoration field and other fields.

Description

technical field [0001] The invention relates to a hardened film, in particular to a hardened film for protecting the anti-reflection layer of photovoltaic glass. Background technique [0002] With the continuous reduction of global fossil fuels and the resulting environmental problems, new types of renewable energy have attracted more and more attention. The field of photovoltaics has also achieved long-term development in recent years due to the use of solar energy, an inexhaustible energy source with zero emissions and pollution-free energy, as an energy source. [0003] Due to the difference in refractive index between photovoltaic glass and air in the current photovoltaic module structure, photovoltaic glass still partially reflects visible light. By coating a layer of anti-reflection layer on the surface of photovoltaic glass, the transmittance of light can be greatly improved, thereby increasing the power of photovoltaic cell modules. Anti-reflection glass has also b...
