Embodiment 1

[0038] 1. Preparation of self-cleaning high AR coating solution:

[0039] Step a, utilize soap-free emulsion polymerization method to prepare cationic polystyrene emulsion:

[0040] In terms of mass percentage, 2% comonomer acryloyloxyethyltrimethoxyammonium chloride and 82.5% water are placed in a reaction vessel, 15% styrene is added for stirring, and the temperature is raised to 50° C. under nitrogen protection, and then 0.5% potassium persulfate initiator aqueous solution is added dropwise, and cationic polystyrene emulsion is obtained after reaction.

[0041] Step b. Mix the cationic polystyrene emulsion and solvent ethanol evenly. The amount of solvent is to dilute the cationic polystyrene emulsion to a solid content of 1%, and then add the silicon source substance tetramethoxysilane under stirring at 15°C The reaction is carried out to obtain the nano-core-shell silica microsphere sol coated with polystyrene by silica. In this step, the mass ratio of the solid mass of...

Abstract

The invention relates to the technical field of anti-reflection coating solutions, particularly to a self-cleaning highly-anti-reflection coating solution, a preparation method thereof and a self-cleaning highly-anti-reflection solar glass. The preparation method of the self-cleaning highly-anti-reflection coating solution comprises preparing nanometer core-shell silicon dioxide colloidal microspheres, coating titanium dioxide layers onto the surfaces of core-shell silicon dioxide colloidal microspheres to obtain nanometer core-shell silicon dioxide / titanium dioxide colloidal microspheres, andthen diluting the nanometer core-shell silicon dioxide / titanium dioxide colloidal microspheres until the solid content is 3-10% to obtain the self-cleaning highly-anti-reflection coating solution. The preparation method of the self-cleaning highly-anti-reflection coating solution reduces the mass ratio of titanium dioxide / silicon dioxide, and meanwhile, maximizes the effective area of exposure, solves the technical problems of contradiction of increasing transmittance and self-cleaning effects and greatly improves the problem of low porosity of coating membranes with solid silicon dioxide asthe main component in the prior art.

Description

technical field [0001] The invention relates to the technical field of antireflection and antireflection coating solution, in particular to a self-cleaning high antireflection coating solution, a preparation method thereof, and a self-cleaning high antireflection solar glass. Background technique [0002] Solar photovoltaic is one of the clean energy sources with the most development potential at present. In order to improve the photoelectric conversion efficiency, most photovoltaic glass manufacturers are making efforts to improve the light transmittance of photovoltaic glass, that is, to add a layer on the glass by using the principle of light interference. Anti-reflection coating, many anti-reflection coating solutions on the market mostly achieve the effect of increasing light transmittance by about 3%, but there is little room for further improvement. With the development of modern industry and urban construction, environmental pollution such as air and water is serious...
