The invention belongs to the technical field of decoration material floors, and relates to a multi-layer composite floor with an electronic wire curing film and a manufacturing method thereof. The multi-layer composite floor with the electronic wire curing film sequentially comprises a UV (ultraviolet) paint film, the electronic wire curing film and a multi-layer substrate layer from top to bottom, wherein the multi-layer substrate layer is a plywood which is formed by transversely and longitudinally staggering and laminating fast-growing wood single plates; the upper surface of the plywood isadhered with the electronic wire curing film by polyvinyl alcohol glue; the surface of the electronic wire curing film is adhered with a decoration wood texture pattern layer, and the thickness of the electronic wire curing film is 0.2 to 0.6mm. The multi-layer composite floor manufactured by the manufacturing method has the advantages that the surface is sprayed with the UV paint film, so that the defect of poor burning-resistant property of the electronic wire curing film is effectively overcome; because the molecular structure of the electronic wire curing film is highly regular, the anti-bending fatigue property and the elasticity are very strong; the color permeability of surface texture is good, the foot feel is good, the surface density is strong, the cleaning is easy, and the easiness in scratching is avoided.
