Embodiment 1

[0017] A primer oil for cold ironing machines, which is made of the following raw materials by mechanical physical stirring: 35 parts of water-based acrylic resin, 40 parts of water-based polyurethane resin, 2 parts of ethanol, isopropyl 2 parts of alcohol, 0.2 part of antifoaming agent SP-843 water-based varnish defoamer, 0.3 part of antifoaming agent APR874 water-based varnish defoamer, 0.1 part of raw material wetting agent TEGOWet 270 substrate wetting agent , Surface wetting agent FY-3102 wetting agent 0.1 part.

[0018] Effect: The primer oil has poor affinity.

[0019] According to the test, the unit area of ​​hot stamping peeling off of the cold foil film reaches 1.5%.

Embodiment 2

[0021] A primer oil for cold ironing machines, which is made by fully stirring the following raw materials by weight: 45 parts of water-based acrylic resin, 50 parts of water-based polyurethane resin, 6 parts of ethanol, isopropyl 6 parts of alcohol, 0.5 part of antifoaming agent SP-843 water-based varnish defoamer, 0.8 part of antifoaming agent APR874 water-based varnish defoamer, 0.3 part of raw material wetting agent TEGOWet 270 substrate wetting agent , 0.7 parts of surface wetting agent FY-3102 wetting agent.

[0022] Effect: The affinity of primer oil is average.

[0023] According to the test, the unit area of ​​the hot stamping shedding of the cold film reaches 1%.

Embodiment 3

[0025] A primer oil for cold ironing machines, which is made by fully stirring the following raw materials by weight: 39 parts of water-based acrylic resin, 42 parts of water-based polyurethane resin, 3 parts of ethanol, isopropyl 3 parts of alcohol, 0.3 part of antifoaming agent SP-843 water-based varnish defoamer, 0.5 part of antifoaming agent APR874 water-based varnish defoamer, 0.2 part of raw material wetting agent TEGOWet 270 substrate wetting agent , 0.7 parts of surface wetting agent FY-3102 wetting agent.

[0026] Effect: The affinity of primer oil is average.

[0027] According to the test, the unit area of ​​hot stamping peeling off of the cold foil film reaches 0.8%.

Abstract

The invention relates to an openpore coating for a cold-hot combined machine, in particular to an openpore coating which can improve surface affinity during printing and belongs to the field of coatings. The openpore coating is prepared by mechanically and physically stirring the following raw materials in part by weight: 35 to 45 parts of waster-based acrylic resin, 40 to 50 parts of waster-based polyurethane resin, 2 to 6 parts of ethanol, 2 to 6 parts of isopropanol, 0.5 to 1.5 parts of defoaming agent and 0.2 to 1 part of wetting agent. The openpore coating has the characteristics of achieving high surface affinity, realizing a process of firstly printing and secondly stamping in the cold-hot stamping process, greatly decreasing production cost, improving production speed and the like.

Description

technical field [0001] The invention relates to a primer for cold ironing machines, in particular to a primer that can improve surface affinity during printing, and belongs to the field of coatings. Background technique [0002] The working principle of in-line cold stamping in offset printing in the prior art is, firstly, use the traditional offset printing ink supply unit and offset printing plate to coat high-viscosity glue on the printing material; then, use pressure to compound the bronzing foil on the printing material; finally , peel off the hot stamping foil, and let the hot stamping foil transfer to the glue-coated part of the printing material. Hot stamping technology refers to the use of special metal hot stamping plates to transfer the hot stamping foil to the surface of the printing material by means of heating and pressure. High speed, low cost, hot stamping before printing, printing after stamping, and positioning graphics are the advantages of cold stamping,...
