The invention belongs to the technical field of pipeline, and discloses a composite metal plastic corrosion-proof wear-resistant material and preparation technology thereof. The method mainly comprises the following technical schemes: taking and adding polypropylene, polyolefin, polytetrafluoroethylene and polyethylene adhesive to the surface of a metal base through abrasive blasting and napping and heating treatment by mixing extruding, pelleting and grinding; uniformly attaching plastic powder material to the inner wall surface after rotation; and uniformly attaching the material on the inner wall of the steel pipe after dissolution so as to form a composite metal plastic corrosion-proof wear-resistant body after cooling solidification. In the composite metal plastic corrosion-proof wear-resistant material prepared by the technology, the high-temperature characteristic of plastic material layer is greatly improved, the service life is prolonged, and the acid and alkaline resistant performance is improved.
