Embodiment 1

[0083] The first step of graphic design: make 3 films. The first sheet is a pattern and text (trademark), but its border size is 0.5 mm thicker than the real trademark; the second sheet is the real trademark size; the third sheet is a trademark, but its border size is 1 thicker than the real trademark mm.

[0084] The second step of plate making and printing: use the first film to make a screen printing plate with a mesh of 250, use the second film to make a screen printing plate with a mesh of 380, and use the third film to make a screen printing plate with a mesh of 180 Silkscreen version.

[0085] The third step screen printing: on the carrier film side of the coating release agent, carry out the first pass printing with the first screen printing plate, and print the metal varnish liquid in the present invention by flat printing; carry out the second screen printing plate with the second screen printing plate Two-pass printing, plane missing printing The metallic red ink ...

Embodiment 2

[0088] According to the description of Embodiment 1, but the red metallic ink is changed to the yellow metallic ink of the present invention to make a yellow trademark, and the yellow trademark is hot-melt transferred to the metal to make a top-level adhesion. It has been confirmed by testing and comparison that performance indicators such as fastness, gloss, abrasion resistance, weather resistance, and solvent resistance exceed those of metal printed matter baked at high temperature for a long time.

Embodiment 3

[0090] According to the description of Embodiment 1, but the red metallic ink is changed to the blue metallic ink of the present invention to make a blue trademark, and the blue trademark is hot-melt transferred to the metal to have top adhesion. It has been confirmed by testing and comparison that performance indicators such as fastness, gloss, abrasion resistance, weather resistance, and solvent resistance exceed those of metal printed matter baked at high temperature for a long time.

Abstract

The invention relates to a method for preparing macromolecule metallic printing ink with hot-melt transfer function, a bonder and finish liquid. Patterns and characters (trademarks) prepared by silk screen skip printing can be transferred onto the surface of a metal article by hot melting. Therefore, top-level firmness is achieved, and long-term high-temperature roasting is not required.

Description

technical field [0001] The invention relates to the preparation of hot-melt transfer functional polymer metal printing ink, adhesive, varnish liquid and metal printing. Background technique [0002] Metal materials commonly used in industry include tinplate, stainless steel, aluminum, copper, etc., and the surface printing and decoration of their parts have always been regarded as a research topic with great commercial value. For a long time, metal printing inks have used amino resin and epoxy resin as binders. The inks are thermosetting. Printed patterns and characters (trademarks) need to be baked at high temperatures for a long time to make the ink binders change from low molecular weight to low molecular weight. The macromolecular network structure forms a tough ink film. For example, when using amino resin ink, it needs to be baked at 150°C for more than half an hour to have good adhesion. To use epoxy resin ink, you need to add a certain amount of curing agent before...
