preparation example Construction

[0057] Another embodiment of the present invention also provides a method for preparing the UV-LED curing pad printing ink as described above, comprising the following steps:

[0058] Add acrylic acid prepolymer, monomer and dispersant to the mixer, stir at 600 rpm for 10 minutes, and stir evenly to obtain a mixture;

[0059] Put the adhesion promoter, photoinitiator, pigment, and surface additive into the mixture, disperse for 30 minutes at a speed of 1000 rpm, and stir evenly to obtain a premix;

[0060] The premix is ​​ground to a fineness of less than 10 μm by a three-roll machine to obtain a UV-LED curable pad printing ink.

[0061] Another embodiment of the present invention also provides the application of the above-mentioned UV-LED curable pad printing ink in special advertisements, automobile industry, capacitor aluminum case, computer keyboard, instrument and meter.

Embodiment 1

[0072] This embodiment is used to illustrate the UV-LED curing pad printing ink disclosed in the present invention and its preparation method, including the following steps:

[0073] Step 1: According to the components and mass ratio listed in Example 1 in Table 1, under the mixer in the starting state of the batching kettle, add polyester acrylic resin, polyurethane acrylic resin, monomer, dispersant, and stir at 600 rpm for 10 minutes , to obtain a mixture.

[0074] Step 2: According to the components listed in Example 1 in Table 1 and the mass ratio, the adhesion promoter, photoinitiator, pigment, surface additives, and anti-scratch additives are put into the mixture, at a speed of 1000 rpm / min for 30min to obtain a premix.

[0075] Step 3: Grinding the above-mentioned premix to a fineness of less than 10um through a three-roller machine to obtain UV-LED curable pad printing ink.

Embodiment 2～7

[0077] Embodiments 2 to 7 are used to illustrate the UV-LED curing pad printing ink disclosed in the present invention and its preparation method, including most of the operating steps in Embodiment 1, the difference being:

[0078] In the step 1 and the step 2, the components and mass ratios listed in Examples 2 to 7 in Table 1 were used to prepare UV-LED curing pad printing ink.

Abstract

The invention provides UV-LED curing transfer printing ink in order to solving the problem that existing transfer printing ink is poor in adhesive force. The UV-LED curing transfer printing ink is prepared from, by mass, 40-60 parts of crylic acid prepolymer, 5-25 parts of adhesion promoter, 5-15 parts of monomers, 5-15 parts of photoinitiator, 5-25 parts of pigment and 0.3-3 parts of surface aid.Meanwhile, the invention discloses a preparation method and application of the UV-LED curing transfer printing ink. The adhesive force of the UV-LED curing transfer printing ink on all kinds of basematerials is good, the alcohol resistance and boiling water resistance are excellent, the durability at high temperature and high humidity is good, the scratch resistance is prominent, and the workingtime is short.

Description

technical field [0001] The invention belongs to the technical field of pad printing inks, and in particular relates to a UV-LED curing pad printing ink, a preparation method and an application thereof. Background technique [0002] Pad printing is one of the special printing methods. It can print text, graphics and images on the surface of irregular shaped objects, and is now becoming an important special printing. In special advertisements, the automobile industry, and the surface printing of many electronic products such as computer keyboards, instruments, and meters, all are done by pad printing. [0003] The adhesion of pad printing ink to the printing material is mainly based on the matching of the physical and chemical properties of the resin in the ink and the printing material. Solvent-based inks can conveniently choose various types of resins to achieve good adhesion. Therefore, solvent-based ink systems occupy a dominant position in pad printing inks. [0004] ...
