The invention belongs to the technical field of composite processing, and relates to a natural fiber-reinforced thermoplastic composite material prepreg tape, and a preparation method thereof. The method comprises the following steps of (a) cutting the natural fiber-reinforced thermoplastic composite material prepreg tape and laying; (b) heating the prepreg tape layer into an infrared-ray oven and melting; (c) putting the melted layer into a cold press machine to carry out cold press and cooling to obtain a sheet material; and (d) after the cooling process is finished, cutting the obtained sheet material, punching, polishing, cleaning burs, carrying out precision grinding, spraying paint and applying a surface to obtain a skateboard surface. The prepared natural fiber/thermoplastic resin skateboard surface can be stored for a long time, and after hot press, the natural fibers can be impregnated by the resin thoroughly, so that the material particularly the natural fibers can be kept dry. The natural fibers ar
