Embodiment Construction

[0023] The present invention will be further described below in conjunction with embodiment.

[0024] In the embodiment of the present application, a UV-LED magenta ink for iron printing is given, including photoinitiator, magenta pigment powder, prepolymer, reactive diluent and auxiliary agent. The mass parts of each component are as follows: 5-10 parts of photoinitiator, 17-22 parts of magenta pigment powder, 55-65 parts of prepolymer, 5-10 parts of reactive diluent, and 3-6 parts of other additives.

[0025] Each component is made up according to the better quality parts: 8 parts of free radical photoinitiator, 20 parts of magenta pigment powder, 60 parts of prepolymer, 7 parts of reactive diluent, and 5 parts of other additives.

[0026] The photoinitiator is a free radical photoinitiator.

[0027] The pigment powder is an organic pigment.

[0028] The prepolymers are polyester acrylates, epoxy acrylates and acrylated polyesters.

[0029] The reactive diluent is an acry...

Abstract

The invention relates to the technical field of printing, in particular to UV-LED fuchsin ink for metal printing, which is prepared from the following components in parts by mass: 5-10 parts of a photoinitiator, 17-22 parts of fuchsin pigment powder, 55-65 parts of a prepolymer, 5-10 parts of a reactive diluent monomer and 3-6 parts of an auxiliary agent. The UV-LED fuchsin ink for metal printinghas the advantages of energy conservation, environmental protection, high production efficiency, low unit consumption cost and the like.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a UV-LED magenta ink for iron printing. Background technique [0002] At present, in the field of iron printing, most of the production processes use traditional thermosetting inks. After the ink printing process is completed, it is necessary to connect a tens of meters of high-temperature drying room to heat the tinplate printing material, so that the solvent of the ink layer on the surface of the tinplate material is volatilized and then cured and dried. The operation of the drying room needs to burn a large amount of gas, so that the temperature of the drying room can be maintained at 140°C-170°C for a long time. This process consumes a lot of gas and will generate a large amount of VOCs (volatile organic compounds). Subject does not match. There is also a part of the production process that uses UV ultraviolet curing inks. UV mercury arc lamps are installed in the printing ...
