Problems solved by technology

[0004] Provide a thermoforming plastic printing ink using ultraviolet-infrared drying technology, which can overcome the deficiencies in the existing technology, not only solve the harm to human health and environmental pollution caused by solvent-based inks, but also overcome the UV drying and curing ink banding. In particular, it can meet the printing suitability of plastic products using the "vacuum thermoforming" process; it is easy to make, easy to apply, safe and pollution-free in use, and can improve product quality

Embodiment Construction

[0009] 1. Raw materials and selection of components

[0010] 1. The prepolymer, also known as an oligomer, is an ultraviolet curable resin, hereinafter referred to as A, which is a low-molecular polymer containing unsaturated functional groups and is the most important component in ultraviolet curable inks. Its performance has great influence on the curing process. And the properties of the cured film play a decisive role. The photoinitiator under ultraviolet irradiation can make the prepolymer and the active monomer into an excited state, continuously cross-link and polymerize, and quickly solidify into a film. It can be composed of one, two or three substances Composition, selected materials are as follows:

[0011] Epoxy acrylic resin, such as: HL-103 series bisphenol A epoxy acrylate [2], modified epoxy acrylic resin HL-140 [1]; ethoxylated bisphenol A diacrylate resin [1];

[0012] Polyurethane acrylic resin, such as: aliphatic polyurethane acrylic resin HL-203Z[2]; poly...

Description

technical field [0001] The invention belongs to the field of printing ink, and relates to a thermoforming plastic printing ink using ultraviolet-infrared drying technology. Background technique [0002] In the prior art, plastic printing inks are roughly divided into two categories, one is solvent-based inks, which have the advantage of having good temperature and pressure adaptability in the "vacuum thermoforming" process, that is, they can withstand industrial processes The disadvantage is that this type of ink contains a large amount of flammable, explosive, volatile and harmful organic solvents, such as xylene, acetone, ethyl acetate, etc., so it not only gives It has caused great harm to the health of workers and also caused great pollution to the environment. Therefore, it has been included in the national dangerous goods control catalogue. Western countries have adopted legal means to restrict this type of ink; the other type is ultraviolet drying and curing ink. It ...
