Embodiment 1

[0046] Embodiment 1: A kind of printing ink, the included components and corresponding parts by weight are shown in Table 1, and are prepared through the following steps:

[0047] Step 1, stirring the oily solvent and the colorant according to the parts by weight;

[0048] Step 2, fully mixing the phenolic resin, curing accelerator, polyethylene wax and the oily solvent obtained in Step 1 according to the parts by weight to form the first mixture;

[0049] Step 3: Add tert-butylhydroquinone to the first mixture obtained in Step 2 according to parts by weight, mix thoroughly, filter to remove impurities, and obtain printing ink.

[0050] Wherein, the vegetable oil is soybean oil; the particle size of the coloring agent is 0.01 μm;

Embodiment 2

[0051] Example 2: a printing ink, the difference from Example 1 is that the components included and their corresponding parts by weight are shown in Table 1.

Embodiment 3-5

[0052] Example 3-5: a printing ink, the difference from Example 1 is that the components included and their corresponding parts by weight are shown in Table 1. During preparation, in step 1, the nano-microcrystalline cellulose colloid, oily solvent, and coloring agent are first stirred and mixed, and then ultrasonically treated; when stirring and mixing, the rotating speed is 300rpm, and the stirring time is 30s; the frequency of ultrasonic emulsification treatment 60kHz, ultrasonic treatment time is 1min. Wherein, the nano-microcrystalline cellulose is spherical, and the nano-microcrystalline cellulose colloid contains 0.01-0.025 wt% of the nano-microcrystalline cellulose, and the rest is ethanol.

[0053] The components included in Table 1 Embodiment 1-5 and their corresponding parts by weight are shown in Table 1

Abstract

Belonging to the field of printing technology, the invention discloses a printing ink and a preparation technology thereof. The printing ink comprises the following components by weight: 18-20 parts of a colorant; 0.98-1.08 parts of a curing accelerator; 0.19-0.23 part of tert-butyl hydroquinone; 31-39 parts of an oily solvent; 18-22 parts of phenolic resin; and 1.8-2 parts of polyethylene wax. The colorant includes at least one of benzidine yellow, pigment carbon black, lithol magenta and phthalocyanine blue, and has a particle size of 0.01-0.02micrometer. The curing accelerator includes at least one of cobalt iso-octoate and manganese iso-octoate. The printing ink provided by the invention has the advantages of bright color and moderate drying speed.

Description

technical field [0001] The invention relates to the technical field of printing, more specifically, it relates to a printing ink and a preparation process thereof. Background technique [0002] In the process of comparing printing inks, the color, rheological properties, and drying properties of printing inks are the most critical. They should have bright colors, good printing adaptability, and appropriate drying speed. [0003] However, many printing inks currently on the market have many disadvantages, such as: too thick or too thin, which makes it difficult to control the drying speed, which in turn easily brings inconvenience to the printing operation. Contents of the invention [0004] In view of the deficiencies in the prior art, the first purpose of the present invention is to provide a printing ink with the advantage of moderate drying speed. [0005] To achieve the above object one, the present invention provides the following technical solutions: [0006] A pri...
