Problems solved by technology

Its technical thinking is mainly to achieve better compatibility between the resin and the system through molecular design, and does not involve the interaction between the resin and silica sol to achieve the technical design of the closed pores on the surface of the anti-reflection film; and it is in the process of preparing the coating solution , It also needs to mix silica sol and template agent and add silane coupling agent before heating and heating reaction treatment. The steps of preparing coating solution are cumbersome and consume a lot of energy.

Abstract

The invention discloses an anti-reflection coating liquid with a surface hole sealing function, a preparation method thereof, anti-reflection coated glass and a photovoltaic module, wherein the anti-reflection coating liquid comprises the following components in percentage by mass: 50%-60% of a carrier solvent, 27%-35% of a film forming substance, 11.5%-15.5% of a resin diluent and 0.005%-0.015% of a pH regulator. The resin pore-forming agent comprises the following raw material components in percentage by mass: 34%-45% of a monomer composition, 54.5%-65% of a dispersing solvent and 0.5%-1% ofan initiator. The compatibility of the resin pore-forming agent and the silica sol and the interaction situation of the resin pore-forming agent and the silica sol in the film forming, curing and toughening stages of the coating liquid are comprehensively considered, and the resin pore-forming agent is synthesized through molecular design. The resin pore-forming agent not only has good compatibility with silica sol, but also can interact with the silica sol in a curing and toughening stage to realize surface pore closing of an anti-reflection film layer. Based on the synthesis of the resin pore-forming agent, pore closing of the surface of a film layer can be realized without adding a pore-sealing substance, so that the types of raw materials in the formula of the antireflection coating liquid are reduced.
