Embodiment 1

[0027] Embodiment 1 (blue ink)

[0028] Accurately weigh each raw material according to the following weight, 45g of epoxy acrylate half ester, 14g of difunctional polyurethane acrylate, 0.1g of 2,6-di-tert-butyl p-cresol, 20g of glycidyl methacrylate, 6511.5g, diphenyl Methanone 1.5g, 11731.5g, titanium dioxide 8g, phthalocyanine blue 6g, start stirring at 300-400rpm, pre-disperse for 20 minutes, after the dispersion is uniform, pass through a three-roll mill controlled by cooling water, and roll twice. Then add 1.5g of dicyandiamide and 0.8g of PN-230, stir evenly, pass the material through a three-roll mill controlled by cooling water, and roll it once, and the fineness is required to be below 10μm. Add 0.5g of silicone oil, 0.5g of TEGO FoamexN and 8g of methacrylate to the dispersed ink. Stir at medium speed for 20 minutes, stir evenly, and it is the finished product.

Abstract

The invention provides ultraviolet-thermal dual-curing glass printing ink. The glass printing ink comprises resin containing epoxy groups and double bonds, urethane acrylate, acrylic ester active monomers, and the glass printing ink further comprises a latent curing agent, photoinitiator, promoter, an antifoaming agent, a flatting agent, padding materials, a polymerization inhibitor and organic dyestuff. The printing ink is cured type glazed printing ink, excellent adhesive force is achieved on various types of glass, and the printing ink has the advantages of being good in water resistance, solvent resistance and grease resistance, free of net-blocking and high in ultraviolet curing speed, the printing ink is particularly suitable for being used for printing some certain exquisite images and texts, a full, distinct, bright and sharp printing effect is achieved, and meanwhile the high hiding rate is achieved.

Description

technical field [0001] The invention belongs to the technical field of inks, and in particular relates to an ultraviolet-heat dual curing glass ink and a preparation method thereof. Background technique [0002] Ink products in the prior art generally belong to high-temperature sintering inks, which need to consume a large amount of energy; in addition, many products use volatile solvents, which will pollute the environment; although existing water-based inks avoid using volatile solvents, the environment is relatively Friendly, but the curing speed of water-based ink is slow, it usually takes a week to reach a higher strength, and in the heat curing process, the curing surface is easily polluted, and in the case of multi-color overprinting, frequent operations are required, which is very inconvenient to use; now UV-curable glass inks on the market have the advantages of environmental protection, rapid curing, and improved product production efficiency. However, UV-curable g...
