The application belongs to the technical field of functional pigments, and particularly relates to a preparation method of high-light-resistance composite pigments. The preparation method of the application is that: after pretreatment and cleaning, hexagonal boron nitride is obtained to be modified boron nitride nanosheet, and then the modified boron nitride nanosheet is compounded with organic pigments to obtain ideal high-light-resistance composite pigments. The modified boron nitride nanosheet used in the application can be better combined with the organic pigments by using the principle of entropy increase, the rich electron boron-nitrogen plane of the hexagonal boron nitride and the aromatic conjugated system of the lithol red molecules produce pi-pi stacking interaction, and then the two are driven to self-assemble to form high-light-resistance composite pigments, and the high-light-resistance composite pigments form a structure that is compact. The high-light-resistance composite pigments obtained by the application still maintain the chemical structure and gloss of the original organic pigments, and have excellent stability and good light resistance, and the problem of poor light resistance of the organic pigments is solved.
