The invention discloses a plastic alloy, a preparation method and application thereof, belongs to a composition using a macromolecular compound as a raw material and a preparation method thereof, in particular to a composition of a macromolecular compound using super-high density polythene and polyurethane as main raw materials. The invention discloses a technique for preparing a UHMWPE-LCPU-EAA plastic alloy using the super-high density polythene and the polyurethane as the main raw materials, wherein the plastic alloy and a steel plate or a steel pipe have quite high adhesive strength, so as to ensure that a composite layer does not to drop off and block a pipeline, reduce flowing resistance, resist corrosion and abrasion, and improve service life. The composite steel pipe taking the plastic alloy as a lining material provides a material transmission pipeline with long service life, corrosion resistance and abrasion resistance for the chemical industry, and provides a new pipeline for urban main water suppl
