The invention belongs to the technical field of polyamide materials and discloses an oxidation and aging resistant polyamide material for automobile door frame trim strips. Polyamide resin, Antioxidant H3386 and silicon-containing hyperbranched polyester are melt-blended, extruded and granulated in a twin-screw extruder, followed by injection molding to produce the target material. The sulfur and silicon elements in silicon-containing hyperbranched polyester endow the material with good flame retardancy, oxidation resistance and aging resistance. Rich amide groups in hyperbranched polyester ensure high compatibility with polyamide, and the hyperbranched structure further strengthens the tensile properties of the polyamide composite.
