The invention provides a coating sunshade composite material with high reflectivity. The composite material comprises a polyester base material layer, wherein the two side surfaces of the polyester base material layer are coated with a polyvinyl chloride (PVC) thin film layer respectively; a reflecting layer is coated on one side surface of each PVC thin film layer and comprises a PVC base coating layer and a PVC top coating layer; and the aperture rate of the composite material is 2 to 6 percent. The invention also provides a preparation method for the composite material. The composite material has good sunshade and heat-isolation effects.
