Problems solved by technology

[0006] 1. Add Ti component to form a super-hydrophilic structure, but if the addition amount is too low, the anti-fouling performance of the membrane surface will not be effectively improved; but if the addition amount exceeds a certain value, the anti-reflection rate of the membrane surface will be significantly reduced
[0007] 2. Form a micro-nano structure on the glass surface by sputtering to improve the anti-fouling performance of the film surface. The advantage of this method is that it is easier to control the thickness of the film layer, but its cost is high, and it is difficult to produce large-scale coatings.

Abstract

The invention discloses a hole sealing agent for improving the anti-fouling performance of an antireflection coating, a preparation method of the hole sealing agent and an antireflection coating solution, and the hole sealing agent comprises the following components in percentage by mass: 10-40% of low-hydrogen silicone oil, 25-35% of allyl polyether, 30-60% of a solvent and 10-20 ppm of a catalyst. According to the antireflection coating solution, the hole sealing agent for improving the anti-fouling performance of the anti-reflection coated glass is added, the surface energy of the hole sealing agent is low, by adding into an antireflection coating solution, migration to the surface of the film layer is easy, in a high-temperature curing process, the anti-fouling agent can be crosslinkedwith the organic silicon resin in the coating solution to form the compact structure so as to provide the hole sealing effect on the surface of the film layer, such that the binding force between theEVA adhesive film, the sealing silica gel and other media and the film layer surface group is reduced, and the excellent anti-fouling performance is provided on the basis of the high transmittance ofthe film layer when the anti-fouling agent is used in the antireflection coating.
