The present invention relates to a porous silica coating composition and a method for producing the same, and more particularly, in the silica coating composition, 4 to 5 mol of water, 10 to 11 mol of ethanol, and 0.55 to 0.6 mol of polyglycol per 1 mol of silicon. It includes, and relates to a porous silica coating composition comprising the acid solution so that the pH of the entire composition is adjusted to 1 ~ 1.5 and a method for producing the same, according to the present invention, the porous silica coating excellent in the surface strength and transmittance of the film at the same time There is an effect of providing a composition and a method for producing the same. |
