[0049] A printing ink with high adhesion, the content of each component is shown in the table below,

[0050] Table 1.

[0051]

[0052] Among them, shell powder and coral powder are obtained by crushing natural shells and corals, with a particle size of ≤10 μm; commercially available sodium polyacrylate is sodium polyacrylate with a degree of polymerization of 12 and a sodium polyacrylate content of ≥90%; n-butanol is commercially available n-butanol with a purity of ≥99%; in actual production, disperse dyes can be selected from low-temperature, medium-temperature or high-temperature disperse dyes of different colors according to needs, and the disperse dye used in this example is C.I. Disperse Red 60.

[0053] Preparation

[0054] The technical process of the preparation method of the high adhesion printing ink of embodiment 1-6 is as figure 1 As shown, specifically include the following steps,

[0055] Weighing: Weigh chlorinated polypropylene resin, polyacrylic acid ...

Embodiment 7-12

[0061] A printing ink with high adhesion, the content of each component is shown in the table below,

[0062] Table 2.

[0063]

[0064] Examples 7-9 are based on Example 3, and differ from Example 3 only in that the amount of sodium polyacrylate (polymerization degree 12) is different, which are 3kg, 4kg, and 5kg in sequence.

Embodiment 10

[0065] Embodiment 10-12 is based on embodiment 9, and the difference with embodiment 9 is only: select commercially available polyacrylate sodium polyacrylate content ≥ 90% that the degree of polymerization is 14 in embodiment 10; Commercially available sodium polyacrylate with a degree of polymerization of 16 and a content of sodium polyacrylate ≥ 90% was selected; in Example 12, a commercially available sodium polyacrylate with a degree of polymerization of 18 and a content of sodium polyacrylate ≥ 90% was selected.

[0066] Preparation

[0067] The technical process of the preparation method of the high adhesion printing ink of embodiment 7-12 is as figure 1 As shown, specifically include the following steps,

[0068] Weighing: Weigh chlorinated polypropylene resin, polyacrylic acid resin, diethylene glycol, thiodiglycol, ethyl acetate, shell powder, naphthalenesulfonic acid formaldehyde condensation polymer, sodium polyacrylate, n-butanol and C.I. Disperse Red 60;

Abstract

The invention discloses high adhesion printing ink. The high adhesion printing ink is characterized by being prepared from the following raw materials in parts by weight: 20 to 30 parts of chlorinatedpolypropylene resin, 10 to 20 parts of polyacrylic resin, 9 to 24 parts of organic solvent, 1 to 5 parts of inorganic filler, 0.2 to 1.0 part of modifier, 0.1 to 0.5 part of cosolvent and 1 to 5 parts of disperse dye, wherein the solvent is prepared by mixing diethylene glycol, thiodiglycol and ethyl acetate in a mass ratio of 1 to 1 to 1, and the inorganic filler is less than or equal to 10 mu min particle size. The printing ink does not need to be doped with graphene, and is low in cost and high in adhesion fastness. The invention correspondingly discloses a preparation method of the highadhesion printing ink. The printing ink prepared with the method has the advantages of high adhesion, and flatness and smoothness after film formation.

Description

technical field [0001] The invention relates to the technical field of printing ink, more specifically, it relates to a high-adhesion printing ink and a preparation method of the high-adhesion printing ink. Background technique [0002] Ink is a substance used to form graphic information in the printing process. It is a paste-like adhesive body with a certain fluidity composed of colored bodies (such as pigments, dyes, etc.), linking materials, filling (filling) materials, and additional materials. A homogeneous mixture that can be printed and dried on the printed object. Therefore, the ink should have bright colors, good printing adaptability, and appropriate drying speed. In addition, it also has certain application indicators such as resistance to solvents, acids, alkalis, water, light, heat, abrasion resistance, sterilization and mildew resistance. [0003] Fading and discoloration are common problems of ink printing products. In addition to fading and discoloration ca...
