A method for preparing a self-cleaning transparent thermal insulation nanocoating includes steps of (1) preparing an acidic aqueous solution, and adding polyoxyethylene dinonyl phenyl ether and graphene into the acidic aqueous solution; (2) preparing a transparent composite nanosol by adding titanate, zinc alkoxide, ytterbium alkoxide and siloxane into the acid aqueous solution through sol-gel reaction; (3) preparing a primary coating by spraying the transparent composite nanosol onto a glass surface; and (4) spraying a dilute alkaline solution onto the primary coating to condense and crosslink components in the primary coating, so that the self-cleaning transparent thermal insulation nanocoating is in-situ generated.
