摘要： Provided are a method for preparing a transparent coating agent, a transparent coating agent composition, a method for preparing a colored coating agent, and a colored coating agent composition to improve working stability and storage stability by using colloidal silica sol and silane. The preparation method of a transparent coating agent comprises the steps of mixing a silica sol, a silane, an alcohol and a catalyst with stirring to prepare a solution A; mixing a silane and a catalyst with stirring to prepare a solution B; and mixing the solution A and the solution B with stirring and maturing the mixture at a room temperature for a certain time. The transparent coating agent composition comprises 10-60 parts by weight of colloidal silica; 10-50 parts by weight of a first silane; 10-40 parts by weight of an alcohol; and 0.5-5 parts by weight of an acid, wherein the first silane is represented by RSi(OR')3; R is CH3, CH2CH3, CH2CH2CH3, CH2CH2CH2CH3, C6H5 or CH2CH2CH2CH2CH2CH2CH2CH3; and the acid is hydrofluoric acid, hydrochloric acid, sulfuric acid, nitric acid, formic acid, propionic acid or acetic acid.
