Abstract

The invention discloses a preparation method of an antireflection coating liquid. The preparation method comprises the following steps: 1) preparing a silane polymer, wherein the silane polymer is prepared from silane under the condition of an acid catalyst by adopting a sol-gel method; 2) preparing nano microspheres by an emulsion polymerization method: mixing and stirring an active monomer, water, an emulsifier and an initiator for emulsification, heating to 70-90 DEG C, carrying out a heat preservation reaction, adding a stabilizer, continuing the heat preservation reaction, and obtaining the nano microspheres after the reaction is finished; and 3) preparing the anti-reflection coating liquid: uniformly mixing the silane polymer and the nano microspheres to obtain the anti-reflection coating liquid. According to the preparation method of the anti-reflection coating liquid, the nano-microspheres are prepared by adopting an emulsion polymerization method, the particle size is controllable, the process is simple, the reaction time is short, and the production efficiency is high; and the mass ratio of the silane polymer to the nano microspheres is controlled, so that the photovoltaic glass prepared from the coating liquid has moderate film porosity, and the film has high anti-reflection and weather resistance.
