The present invention relates to the technical field of polyphenylene sulfide flame-retardant materials, and discloses a high oil-resistant polyphenylene sulfide flame-retardant material for automotive charging systems. The present invention obtains a high oil-resistant polyphenylene sulfide flame-retardant material for automotive charging systems by mixing, melting and stirring polyphenylene sulfide, a silicon-containing flame retardant, modified benzoxazine and antioxidant 1035, and feeding the mixture into a twin-screw extruder for extrusion. The high oil-resistant polyphenylene sulfide flame-retardant material contains a large amount of silicon elements and has a good flame-retardant effect. Benzoxazine forms a heat-resistant phenolic resin structure at high temperatures, providing excellent flame retardancy. Polyphenylene sulfide and polyphenylene sulfide in modified benzoxazine synergistically resist oil, achieving a good oil-resistant effect. Cardanol has long chains that entangle with polyphenylene sulfide to form a crosslinked network, providing good tensile properties.
