The invention relates to the technical field of TPE elastomers, and discloses a preparation method of an ultraviolet-resistant TPE thermoplastic elastomer material. The invention blends hydrogenated styrene-butadiene-styrene block copolymer SEBS, polypropylene, polystyrene-based ultraviolet absorber, glycidyl methacrylate-grafted polypropylene and antioxidant, adds the mixture into a twin-screw extruder, and performs melt extrusion and granulation to obtain the ultraviolet-resistant TPE thermoplastic elastomer material. The polystyrene-based ultraviolet absorber of the invention has good compatibility with SEBS and polypropylene in the elastomer material, so that the ultraviolet absorber is uniformly dispersed in the elastomer material, which is beneficial to improving the tensile strength, elongation at break and hardness of the material, and simultaneously enhances the ultraviolet aging resistance of the elastomer material.
