Preparation method and application of anti-aging material for asphalt

The invention belongs to the technical field of preparation of modified asphalt materials, and particularly relates to a preparation method and application of an anti-aging material for asphalt. The method comprises the following steps: (1) adding a copper salt and a sulfide salt into an organic solvent, and performing stirring at room temperature until complete dissolution to obtain a precursor solution A; adding a zinc salt and a sulfide salt into an organic solvent, and performing stirring at room temperature until the zinc salt and the sulfide salt are completely dissolved to obtain a precursor solution B; reacting the precursor solution A at a certain temperature to obtain a copper sulfide nanosheet; continuously injecting the precursor solution B, and performing reacting, centrifuging, separating and drying to obtain copper sulfide/zinc sulfide nanosheets; (2) adding the copper sulfide/zinc sulfide nanosheet, an intercalator and an ultraviolet absorbent into n-hexane, adding a dispersing agent, dispersi
