Manufacturing method of transfer printing film

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.

Description

technical field [0001] The invention relates to a method for manufacturing a transfer film, in particular to a method for manufacturing a transfer film by simultaneously combining a wear-resistant base layer and a release layer on the surface of the film. Background technique [0002] refer to figure 1 and figure 2 As shown, the known transfer film or in-mold transfer film, etc., are usually coated or printed with an ink layer 20 on the inner surface of the hardened outer layer 10, and then the metal layer 30 is electroplated on the inner surface of the ink layer 20, and then coated or printed. Adhesive layer 40; In addition, a release layer 50 is coated or printed on the surface of the hardened outer layer 10, and a thin film 60 is implemented on the release layer 50 in addition; After 40 is pasted on the surface of plastic or metal products, such as mobile phone casings, notebook computer casings and other products, the film 60 can be easily torn off by the effect of th...

Problems solved by technology

[0003] But the manufacture mode of the release layer 50 and the thin film 60 of known transfer film or in-mold transfer film, as above-mentioned earlier in hardening outer layer 10 surface coating or the raw material (release agent) of print release layer 50, then The film 60 is pasted on the release layer 50, so at least multiple manufacturing procedures must be carried out to complete it. This will not simplify the manufacturing process, reduce manufacturing costs and increase market competitiveness, and the thickness of the release layer 50 is only 1 μm to 2 μm. After coating, it is easy to be scratched during the manufacturing process, which affects the quality of the product
