The invention discloses a method for preparing a double-component aqueous cellulose acetate butyrate resin. The method comprises the following steps: firstly, preparing an aqueous acrylate modified cellulose acetate butyrate resin and silane coupling agent hydrolysate or an amino resin solution; and by taking the modified cellulose acetate butyrate resin as a component A, and the silane coupling agent hydrolysate or the amino resin solution as a component B, preparing the double-component aqueous cellulose acetate butyrate resin. Compared with a conventional cellulose acetate butyrate resin use method, the method for preparing the aqueous resin is capable of reducing resource waste and environment pollution caused by solvents, the solvent cost of the cellulose acetate butyrate resin in theuse process can be also reduced, and meanwhile the working environment of operators is improved. In addition, the aqueous resin can be well cross-linked and cured at a relatively low temperature, properties of a cellulose ac
