The present invention relates to the technical field of wire harness material preparation, and discloses a wire harness material with good flexibility and easy bending and a preparation method thereof. The mixture is plasticized and pelletized in a twin-screw extruder, and the wire harness material with good flexibility and easy bending is obtained through melt extrusion, strand drawing, air cooling, pelletizing and drying. The material improves the wear resistance, flexibility, chemical resistance, stress cracking resistance and flex resistance of soft polyvinyl chloride (SPVC), endowing the wire coating material with good thermal stability, light resistance and aging resistance. Meanwhile, it has good fluidity, excellent processability, high ignition point and meets the standard of high flame retardancy. The wire coating material of the present invention has good flexibility and excellent bending resistance. During preparation, polytrimethylene terephthalate (PTT) and polybenzoxazole (PBO) are added to modify SPVC, and inorganic fillers such as carbon nanotubes, ultrafine whisker silicon and nano magnesium titanate are added at the same time, ensuring that the wire harness material has the characteristics of good flexibility, high tensile strength, strong crack resistance and high temperature resistance.
