preparation example Construction

[0045] The invention provides a preparation method of the ink composition, comprising mixing epoxy vinyl ester resin, thermosetting hydroxyacrylic resin, silane-modified polyisobutylene resin, polyamide adduct, liquid paraffin, glycerin and organic solvent in proportion uniform, the ink composition can be obtained.

[0046] In the present invention, there is no particular limitation on the order of adding the components in the ink composition, they can be added in batches or together, and finally mixed evenly. Preferably, in order to uniformly mix the components in the ink composition, firstly mix the components except the organic solvent, use a three-roll mill to grind until the fineness is below 10 microns, and add organic solvents during the grinding process. solvent, mixed uniformly to obtain the ink composition of the present invention.

[0047] The present invention also provides a stainless steel workpiece, including a stainless steel substrate and an ink pattern layer...

Embodiment 1

[0053] (1) Mix the components except the organic solvent, and then grind them with a three-roller mill until the fineness is below 10 microns. During the grinding process, add an organic solvent and mix well. The content ratio of each component is as follows; The ink composition of embodiment, denoted as S1;

[0054] Epoxy vinyl ester resin: 8084, vinyl content 42wt% 30%

[0055] Thermosetting hydroxyl acrylic resin: SC341, hydroxyl value 86 mgKOH / g 25%

[0056] Silane modified polyisobutylene resin: EPION TM , silicon content 10wt% 10%

[0057] Polyamide adduct: kingcure 450, amine value 300mgKOH / g 3%

[0058] Liquid paraffin 5%

[0059] Glycerin 6%

[0060] Additives: Defoamer: EFKA2022 0.5%

[0061] Leveling agent: EFKA3883 0.5%

[0062] Wetting and dispersing agent: Kerper-602 0.8%

[0063] Pigment: Carbon Black 6%

[0064] Organic solvent: isophorone, cyclohexanone volume ratio 2:1 13.2%

[0065] (2) Print the ink composition S1 on the surface of the...

Embodiment 2

[0067] The ink composition S2 was prepared by the same method as in Example 1, and transferred to the surface of the stainless steel substrate, and solidified to prepare the stainless steel workpiece S22. The difference was that the components and weight percentages in the ink composition S2 were as follows:

[0068] Epoxy vinyl ester resin: 411-400, vinyl content 33wt% 35%

[0069] Thermosetting hydroxyl acrylic resin: A909, hydroxyl value 70mgKOH / g 22%

[0070] Silane modified polyisobutylene resin: EPION TM , silicon content 15wt% 12%

[0071] Polyamide adduct: kingcure46, amine value 190mgKOH / g 7%

[0072] Liquid paraffin 5%

[0073] Glycerin 5%

[0074] Auxiliary: Defoamer: BYK352 0.5%

[0075] Wetting and dispersing agent: CFC-500HP 0.5%

[0076] Pigment: Iron Red 3%

[0077] Organic solvent: isophorone, cyclohexanone, isobutanol volume ratio 1:0.2:0.2 10%.

Abstract

The invention provides a printing ink composition, which comprises the following components in percentage by weight: 30 to 40 percent of epoxy vinyl ester resin, 20 to 30 percent of thermoset hydroxy acrylic resin, 10 to 15 percent of silane modified polyisobutene resin, 3 to 10 percent of polyamide adduct, 5 to 10 percent of liquid paraffin, 5 to 10 percent of glycerol and 10 to 20 percent of organic solvent. The printing ink composition still can be transferred to the surface of a die from a release film after being surface-dried at room temperature, the transfer patterns are high in accuracy and a transfer process is simplified.

Description

technical field [0001] The invention belongs to the field of ink, and in particular relates to an ink composition, a preparation method thereof and a stainless steel workpiece. Background technique [0002] The various patterns on the surface of the interior and exterior parts of the car can conceal the defects on the surface of the product on the one hand, make the product look beautiful, and meet the needs of vision; Easy to demould. For example, the texture of automobiles is mainly formed on the surface of the mold through chemical corrosion, and the injection molding interior parts are formed after painting. Before chemical etching, it is necessary to form an anti-etching texture pattern on the surface of the mold. Generally, the anti-etching photosensitive ink is sprayed on the entire surface of the mold, and then pasted with soft film. After exposure and development, an anti-etching pattern can be formed on the surface of the mold. However, due to the different shap...
