[0002] Polyether ether ketone is a linear aromatic polymer compound containing chain segments in the molecular backbone, and the constituent unit is oxygen-p-phenylene-oxygen-carbonyl-p-phenylene, which is a semi-crystalline and thermoplastic plastic. Polyether ether ketone has excellent mechanical properties, good self-lubricating property, chemical corrosion resistance, flame retardation, peeling resistance and wear resistance, and can be used in high-end machinery, nuclear engineering and aviation technology, and can also be used as a high-temperature structural material and an electrical insulating material or a reinforcing material prepared by compounding with carbon fibers or carbon fibers.

[0016] The modified spherical zinc oxide is put into the upper solution generated by the reaction of 3-chloropropyltriethoxysilane, 1,3-benzenediol monobenzoate and sodium carbonate, and finally 1,3-benzenediol monobenzoate is grafted on the surface of the modified spherical zinc oxide and the inner cavity of the porous structure by chemical reaction under the action of bismuth isooctoate, to prepare an anti-aging additive. The prepared anti-aging additive has a spherical zinc oxide as a core, and a double-layer coating structure with a tert-butyl acrylamide sulfonic acid as an inner coating layer and a 1,3-benzenediol monobenzoate as an outer coating layer on the surface of the spherical zinc oxide. This makes the finally prepared anti-aging additive have a clear core-shell structure, and the anti-aging additive prepared by the synergistic cooperation of the spherical zinc oxide, the tert-butyl acrylamide sulfonic acid and the 1,3-benzenediol monobenzoate has excellent anti-aging performance. When the anti-aging additive is used as a polyether ether ketone composite material, it can significantly improve the anti-aging performance of the polyether ether ketone composite material, effectively prolong the service life of the polyether ether ketone composite material and ensure the quality of the polyether ether ketone composite material.
