The present invention relates to the technical field of polymer materials, and specifically discloses a flame-retardant polymer composition for new energy vehicles and a production process thereof. The production process of the flame-retardant polymer composition for new energy vehicles comprises the following steps: S1: weighing resin powder, plasticizer, stabilizer, aluminum hydroxide, calcium carbonate, zinc borate, antimony trioxide, calcium stearate, stearic acid, polyethylene wax and antioxidant in parts by weight, and mixing uniformly to prepare a prefabricated material; S2: weighing didecyl phthalate, hybrid flame retardant and compatibilizer in parts by weight, and mixing uniformly to prepare an intermediate material; S3: feeding the prefabricated material and the intermediate material into a twin-screw extruder at a mass ratio of (1–1.2):1 for plasticization and extrusion, followed by pelletization to obtain the final product. The flame-retardant polymer composition for new energy vehicles prepared by the present invention has excellent flame retardant properties.
