The present invention relates to the field of composite materials, in particular to a corrosion-resistant PEEK sealing material for sealing retainers and a preparation method thereof, specifically comprising the following steps: Step 1: subjecting double bond-containing PEEK resin, PTFE micropowder and sodium allylsulfonate to polymerization initiated by UV irradiation to obtain modified PTFE resin; Step 2: grafting oxidized carbon fiber with a silane coupling agent to obtain modified carbon fiber; Step 3: adding PEEK resin, modified PTFE resin, modified carbon fiber, methyl vinyl ether-maleic anhydride copolymer, carbon fiber and lubricant into a twin-screw extruder, mixing uniformly, extruding and pelletizing to obtain the corrosion-resistant PEEK sealing material for sealing retainers. The PEEK sealing material exhibits excellent corrosion resistance, wear resistance and processability, enabling fabrication of sealing retainers with superior sealing performance.
