Embodiment 1

[0025] Embodiment 1: 45Kg epoxy resin ink prepolymer, 2Kg 2, or 4-isopropyl thioxanthone, 3Kg p-dimethylaminobenzoic acid ethyl ester, 0.5Kg p-hydroxybenzoic acid under room temperature condition Ether and 8Kg of tripropylene glycol diacrylate are mixed evenly in a container, and then 12Kg of titanium dioxide pigment with a fineness of ≤20um and 2.5Kg of calcium carbonate with a fineness of ≤20um are added in turn, and fully stirred to make the above materials fully mixed evenly.

[0026] The difference between other embodiments and embodiment 1 is shown in the table below:

[0027] Unit: (Kg)

[0028]

[0029] The fineness of solid materials such as pigments and additives in the above embodiments is ≤20um.

[0030] After measurement, the fluidity of the UV-curable offset printing ink prepared in the above examples is: 20-35mm / room temperature, viscosity: 100-300pa.s / 30°C, drying time: 150-800s / room temperature.

Abstract

The invention discloses an ultraviolet light curing offset printing ink which is formed by epoxide resin printing ink pre-polymer, 2, or 4-isopropyl thioxanthone, dimethylin ethyl benzoate, triethylene glyceryl alcohol methyl acrylate, painting and calcium carbonate. It can adjust the painting ink by different painting craft with the ink moving speed: 2-35mm / normal temperature, the viscosity ratio: 100-300pa.s / 30 deg. and the drying time: 150-800s / normal temperature.

Description

technical field [0001] The invention relates to printing ink, in particular to a high-gloss, high-performance UV-curable offset printing ink. Background technique [0002] UV-curable inks are widely used in the packaging industry, but the existing UV-curable inks have single performance, poor gloss of printed products, difficult to adjust ink properties, and difficult to adapt to complex printing processes, which has become an important factor affecting the printing quality of high-end packaging products. factor. [0003] purpose of invention [0004] The invention provides an ultraviolet curing offset printing ink with high gloss and excellent performance to overcome the deficiencies in the prior art. Contents of the invention [0005] To realize the purpose of the present invention, this UV-curable offset printing ink is characterized in that it is made of the following components in parts by weight: [0006] Epoxy ink prepolymer 50~70 [0007] 2, or 4-isopropylthiox...
