The present invention provides a preparation method and application of a diatomite and zinc oxide composite high-density polyethylene material, belonging to the technical field of solid adsorbent composition materials. Firstly, high-density polyethylene composite material is prepared from diatomite, zinc oxide and polyethylene in a certain proportion. Then, to improve its performance and UV resistance, Tinuvin 770 is added and mixed with the composite polyethylene material in a gear mixer. Subsequently, a twin-screw extruder is set at a certain temperature and speed for extrusion, and the extrudate is cut into microspheres by a tray machine. Finally, these microspheres are injected into an injection molding machine, and a target mold is selected for molding. Meanwhile, when used as a food packaging bag material, it can inhibit the growth of Staphylococcus aureus and Escherichia coli, has a minimum content of UV stabilizer, is a cost-effective and high-performance choice, has strong UV blocking ability, and can well protect the quality of packaged food.
