Problems solved by technology

Most of the initiators used in existing UV inks are small molecular weight free radical initiators. After the curing is completed, the small molecular weight initiators can easily penetrate into the packaged food or medicine through the barrier layer of the packaging material, thereby causing harm to the human body. harm

[0032] (2) Move the mixture in step (1) to a disperser and stir evenly, and stir for 10 minutes under the condition of 800 rpm, so that the mixture is uniformly dispersed, and then ground to a fineness below 10 μm through a three-roller machine, That is, a yellow low-migration UV flexographic ink was obtained.

Embodiment 2

[0034] A low migration UV flexographic ink (red)

[0035] Composed of raw materials in the following weight percentages: EB657 8.0%, CN294 9.0%, 6351 8.0%, EB605 18.0%, TMP(PO)TA 10.0%, EB168 2.0%, Irgacure 127 1.0%, Irgacure754 2.0%, Omnipol BP 2.0%, C.I. Pigment Red 57:1 36.0%, RAD 2500 1.0%, BYK-163 1.0%, 3062 1.0%, BYK-335 1.0%.

[0036] Its preparation method is:

[0037] (1) Weigh EB657, CN294, 6351, EB605, TMP(PO)TA, EB168, Irgacure 127, Irgacure754, Omnipol BP, C.I. Pigment Red 57:1, RAD 2500, BYK-163, 3062 and BYK- 335, add in the dispersion container and mix to obtain the mixture;

[0038](2) Move the mixture in the step (1) to a disperser and stir evenly, and stir for 11 minutes under the condition of 800 rpm, so that the mixture is uniformly dispersed, and then ground to a fineness below 10 μm through a three-roller machine, That is, red low-migration UV flexographic ink was obtained.

Embodiment 3

[0040] A low migration UV flexographic ink (blue)

[0041] Composed of raw materials in the following weight percentages: EB450 6.0%, CN2203 7.0%, 6313 7.0%, EB3701 10.0%, CN386 15.0%, SR9008 3.0%, KIP150 2.0%, Omnipol TX 1.0%, C.I. Pigment Blue 15:4 46.0%, RAD 270 1.0%, BYK-345 1.0%, BYK-991 1.0%.

[0042] Its preparation method is:

[0043] (1) Weigh EB450, CN2203, 6313, EB3701, CN386, SR9008, KIP150, Omnipol TX, C.I. Pigment Blue 15:4, RAD 270, BYK-345 and BYK-991 according to the above proportions, add them into the dispersion container and mix to obtain mixture;

[0044] (2) Move the mixture in step (1) to a disperser and stir evenly, and stir for 12 minutes under the condition of 800 rpm, so that the mixture is uniformly dispersed, and then ground to a fineness below 10 μm through a three-roller machine, That is, the blue low-migration UV flexographic ink is obtained.

Abstract

The invention belongs to the technical field of ink preparation, and in particular relates to low-migration UV flexible printing ink and a preparation method thereof. The low-migration UV flexible printing ink consists of the following raw materials in percentage by weight: 15.0-30.0% of multifunctional polyesteracrylate, 10.0-20.0% of epoxy acrylate oligomer, 5.0-20.0% of a monomer with a special functional group, 0-5.0% of an adhesion promoter, 5.0-10.0% of a molecular weight photoinitiator, 15.0-50.0% of low-migration pigment and 0-5.0% of additives. The low-migration UV flexible printing ink provided by the invention is simple in preparation method, relatively small in fineness, moderate in viscosity, rapid in curing velocity, low in migration capacity, applicable to high-speed machine printing, and high in security.

Description

technical field [0001] The invention belongs to the technical field of ink preparation, and in particular relates to a low-migration UV flexographic ink and a preparation method thereof. Background technique [0002] Ultraviolet (UV) curing is an advanced material surface treatment technology that appeared in the 1960s. It uses ultraviolet light to trigger rapid polymerization and crosslinking of chemically active liquid materials, and instantly solidifies them into solid materials. It is an efficient, Environmental protection, energy saving, high-quality material surface treatment technology. Among them, UV curable inks have fast curing, high coating quality, high hardness, scratch resistance, and corrosion resistance. They conform to the development direction of modern coatings and inks, and have attracted people's attention. They have developed rapidly in the packaging and printing industry and the printed circuit industry. And a wide range of applications, UV curing app...
