Embodiment 1

[0036] A cold transfer film is composed of a base film, a release layer coated on one side of the base film and an ink layer coated on the release layer, wherein the thickness of the release layer is 10-20 μm.

[0037] The base film is a PET film, and the peeling layer is a general fiber powder release agent peeling layer, which is composed of a fiber powder release agent and a solvent; the ink is a fluorocarbon ink (the ink model PVDF).

[0038] Apply the adhesive on the side of the stainless steel workpiece to be transferred with the roller coating method (the viscosity of the adhesive is 60 seconds for the No. The ink layer of the printing film is attached to the surface of the stainless steel workpiece coated with the adhesive, and the machine is used to press at 0.05-0.2MPa for 1 second, and the base film is peeled off, and the transfer printing is firm and the color is not distorted. , Stainless steel with clear pattern and texture.

Embodiment 2

[0040] On the side of the aluminum workpiece to be transferred and the surface of the ink layer of the fluorocarbon transfer film (Dongguan, China, model WP9938), spray the adhesive (the viscosity of the glue is 60 seconds for the No. 2 zat cup), and the adhesive layer The thickness is 10-20μm. After standing for half-drying, stick the ink layer of the fluorocarbon transfer film on the surface of the stainless steel workpiece coated with the adhesive, and press it by hand for 3 minutes to imprint, peel off the base film, and transfer. Get stainless steel with firm paste, undistorted color, and clear pattern and texture.

Embodiment 3

[0042] On the side of the iron workpiece to be transferred and the surface of the ink layer of the fluorocarbon transfer film (Dongguan, China, model WP9938), apply the adhesive (the viscosity of the glue is 60 seconds for No. The thickness is 10-20μm. After standing for half-drying, stick the side of the ink layer of the transfer film coated with the adhesive to the surface of the iron workpiece coated with the adhesive, and use the machine to keep it at 0.05-0.2MPa for 5 seconds. Carry out embossing, heat at 60°C for 3 minutes, peel off the base film, cool to room temperature, and transfer to obtain stainless steel with firm adhesion, undistorted color, and clear pattern and texture.

Abstract

The invention belongs to the technical field of transfer printing, and discloses a cold transfer printing method and a cold transfer printing film for color printing or pattern printing on the surface of metal materials. In this method, the ink on the transfer film is transferred to the surface of a metal workpiece through an adhesive, and the material of the metal workpiece is preferably stainless steel, aluminum or iron. The invention also provides a stainless steel, aluminum or iron workpiece printed with fluorocarbon ink on the surface, and a cold transfer film, the ink on the transfer film is preferably fluorocarbon ink. The cold transfer printing method of the present invention does not need heating, and the color and pattern can be transferred to the surface of the workpiece by embossing, which is easy to produce, and has firm adhesion, no distortion of color, and clear pattern texture. The cold transfer printing method of the present invention realizes the transfer printing of fluorocarbon ink on the surface of metal materials, especially stainless steel, aluminum and iron workpieces, and solves the problem that fluorocarbon ink cannot be transferred on the surface of stainless steel, aluminum and iron materials, and the used The materials are all common materials, easy to obtain, and excellent technical effects have been achieved through technical improvement.

Description

technical field [0001] The invention belongs to the technical field of transfer printing, and in particular relates to a cold transfer printing method and a cold transfer printing film used for color printing or printing on the surface of metal materials. Background technique [0002] The existing methods for transferring colors and patterns on the surface of metal materials are mainly thermal transfer methods. The thermal transfer printing method is to sublimate the ink on the transfer film (or transfer paper) under high temperature, penetrate into the surface of the object, and form colors and patterns after sublimation. The application conditions of the heat transfer method are harsh, the steps are cumbersome, and it is difficult to produce. In addition, due to reasons such as partial escape of ink molecules or contact with air during the heat sublimation process, problems such as decreased clarity and high defect rate are caused. In addition, the heating process of the ...
