A METHOD FOR PREPARING A COATING COMPOSITION HAVING IMPROVED LIGHT TRANSMITTANCE AND ANTI-STATIC FUNCTIONS AND LIGHT REFLECTION REDUCTION FUNCTIONS AND A COATING FILME USING THE COATING COMPOSITION PREPARED BY THE SAME

摘要

The present invention comprises the steps of preparing a silicate sol by adding a colloidal silica dispersion to a solution containing water-soluble ethyl silicate obtained by hydrolyzing tetraethoxysilane using an acid catalyst (S1); (S2) preparing an oxide sol by mixing an aqueous metal oxide fine particle and a colloidal silica dispersion; And (S3) mixing and then polymerizing the silicate sol and the oxide sol; and the light transmittance by the AR (anti-reflective) and the AS (anti-static) and the fractal layer structure The present invention relates to a method for preparing a coating composition having enhanced anti-fouling function, and a coating composition prepared according to the present invention and a coating film prepared by coating the coating composition on a polymer resin material. According to the present invention, an anti-reflective (AR) Coating composition that enhances light transmittance and antifouling function by AS (anti-static) and fractal layer structure by coating on polymer resin material and improves light transmittance and antistatic It is possible to produce a coating film that can prevent contamination by minimizing the adhesion of fine dust to the surface layer of the function and fractal structure.
