Problems solved by technology

At present, the anti-reflection film obtained by the sol-gel process is mainly composed of silica, and the refractive index of its dense structure is about 1.45. Now the anti-reflection coating solution on the market adopts a loose and porous structure to improve the transmittance. That is, the structure of openings or through holes, but this structural feature will make it easy for pollutants or water vapor in the environment to enter the interior of the film or adhere to the surface of the film, thereby affecting the transmittance of the film and making the film show poor performance. At the same time, in the prior art, due to the presence of a large number of hydroxyl groups on the surface of the inorganic silica anti-reflection film, the surface activity is very high, and it is easy to adhere to pollutants, which reduces the transmittance of the film

Abstract

The invention discloses a high-transmittance and anti-fouling coating solution and a preparation method thereof. The preparation method comprises the following steps that 1, a film forming matter solution is uniformly dispersed into a solvent by taking isopropanol as a main solvent under the room temperature condition; 2, a hole sealing structure matter solution and a hole forming matter solution are added into a dispersion solution prepared in the step 1 separately under the high-speed stirring condition; 3, the solution prepared in the step 2 is uniformly stirred and subjected to standing for 1 hour, and then the coating solution can be prepared. According to the coating solution, hole sealing structure matter and a functional auxiliary are used, the good anti-fouling property is provided while the high transmittance is guaranteed, and the condition of widely applying the coating solution to the field of optical devices such as solar cells, photovoltaic glass and flat-panel displayers is met.

Description

technical field [0001] The invention relates to the field of anti-reflection films, in particular to a high-transparency and anti-pollution coating solution and a preparation method thereof. Background technique [0002] Anti-reflection coatings are widely used in solar cells, photovoltaic glass, flat panel displays and other optical devices to reduce the reflection of light from interfaces. At present, the anti-reflection film obtained by the sol-gel process is mainly composed of silica, and the refractive index of its dense structure is about 1.45. Now the anti-reflection coating solution on the market adopts a loose and porous structure to improve the transmittance. That is, the structure of openings or through holes, but this structural feature will make it easy for pollutants or water vapor in the environment to enter the interior of the film or adhere to the surface of the film, thereby affecting the transmittance of the film and making the film show poor performance. ...
