Abstract

The invention relates to the field of antireflection film coating liquid and particularly relates to a template agent for the antireflection film coating liquid as well as a preparation method and application of the template agent. The preparation method comprises the following steps: firstly preparing the template agent: reacting by virtue of at least three monomers, a solvent, an initiator and an aid; preparing silica sol: putting alkoxy silane and a solvent into a reaction container, adding a catalyst at a temperature of the room temperature to 90 DEG C, so as to react; and finally preparing the antireflection film coating liquid: mixing the synthesized template agent and the synthesized silica sol, adding a silane coupling agent to react, and adding a diluent for dilution. By carrying out molecular designing according to the property of the silica sol, the template agent with good consistency with the silica sol is synthesized, so that the development efficiency is improved; and by adding the silane coupling agent, the stability of the antireflection film coating liquid is enhanced, the film forming property of the film coating liquid is improved, and the antireflection rate and dirt resistance of an antireflection film are increased.

Description

technical field [0001] The invention relates to the field of anti-reflection and anti-reflection coating liquid, in particular to a template agent for anti-reflection and anti-reflection coating liquid and its preparation method and application. Background technique [0002] The template plays a vital role in the anti-reflection and anti-reflection coating solution. The template is generally an organic polymer such as resin or emulsion. After the anti-reflection and anti-reflection film is coated, cured, and tempered, the template in the film layer After the agent is burned, a cavity is formed, which reduces the refractive index of the film layer, thereby achieving the effect of anti-reflection and anti-reflection. Therefore, choosing a suitable templating agent is critical to the gain effect of coated glass. [0003] At present, the sol-gel method is the most commonly used preparation method for preparing ultra-clear photovoltaic glass coating solution. The coating solutio...
