Abstract

The invention relates to a manufacturing method of a transfer printing film. The manufacturing method comprises the steps of: mixing a liquid wear resistant substrate raw material and a parting raw material, or mixing a solid wear resistant substrate raw material and a parting raw material; blending the mixed raw materials into a liquid with an aqueous solvent, a natural solvent or an oil solvent; and spraying, coating or printing the blended parting and wear resistant substrate raw materials on the surface of a film. The wear resistant substrate raw material and the parting raw material are automatically separated into a required parting layer and a required wear resistant substrate layer on the surface of the film under physical and chemical change actions of each other, such as different specific gravities of compound compositions, molecular surface tension, repulsive force, reaction mechanisms or binding force, and the like, or under the chemical and physical change actions, such as different reaction speeds, and the like; the parting raw material polymerizes or attaches to the surface of the film to form the parting layer; and the wear resistant substrate raw material polymerizes on the surface to form the wear resistant substrate layer.
