Example Embodiment

[0022] At the same time, the method for preparing the above mirror silver ink disclosed in the present invention includes the following steps:

[0023] (1) Prepare materials according to the following components and content (wt%):

[0024] Aluminum paste 45~59;

[0025] Main body resin 20~30;

[0026] The first solvent 20-30;

[0027] Additive 0.5~1.5;

[0028] (2) Mix the first solvent, the auxiliary agent, the aluminum paste, and the main resin in sequence, and fully stir evenly after adding one of them. The main resin is an ether modified polyurethane resin and a CAB modified acrylic resin prepared in proportion.

[0029] In addition, the present invention also provides a printed matter, which is printed on a substrate using the mirror silver ink disclosed in the present invention. The substrate used is a plastic sheet, and its composition is one or more of PC, PET, PMMA, PE, and PP.

Example Embodiment

[0031] Example 1:

[0032] This example is used to illustrate the ink composition of the present invention and its preparation method and printed matter.

[0033] (1) First weigh the required first solvent according to the formula ratio, then slowly add the required amount of auxiliary agent and stir for 5 minutes; then add the aluminum paste and stir for 15 minutes; finally add the main resin and stir for 15 minutes to get the mirror silver Ink; the components and their contents in the ink composition are as follows:

[0034] The first solvent: (14wt% ethylene glycol butyl ether and 10wt% ethyl acetate) 24wt%

[0035] Additive: EDL-CR200 1wt%

[0036] Aluminum paste: Ciba Metasheen 41-0710 (the thickness of the aluminum sheet is 0.03μm, the average particle size is 10μm) 50wt%

[0037] Main resin: (12.5wt% ether modified polyurethane resin and 12.5wt% CAB modified acrylic resin) 25wt%

[0038] (2) Print the ink composition of step (1) on a PC sheet. The printing screen uses a 270 mesh n...

Example Embodiment

[0039] Example 2:

[0040] The ink composition was prepared by the same method as in Example 1, and the PC sheet was printed, except that the components and contents in the ink composition were as follows:

[0041] First solvent: (14wt% ethylene glycol butyl ether and 10wt% ethyl acid) 24wt%

[0042] Additive: EDL-CR200 1wt%

[0043] Aluminum paste: Ciba Metasheen 41-0710 (the thickness of the aluminum sheet is 0.03μm, the average particle size is 10μm) 55wt%

[0044] Main resin: (10wt% ether modified polyurethane resin and 10wt% CAB modified acrylic resin) 20wt%

[0045] Through the above steps, a printed matter A2 is obtained.

Abstract

The invention relates to a mirror-like silver ink and a preparation method thereof, and a printed matter. The components of the mirror-like silver ink include aluminum paste, a matrix resin, a first solvent and an auxiliary, wherein the matrix resin is composed of an ether modified polyurethane resin and a cellulose acetate butyrate modified acrylic resin. The mirror-like silver ink disclosed in the invention has excellent resistance to high temperature and has wider application range; the ink can be combined with the in-mold labeling injection molding process to show new decoration effect and even to replace the appearance effect that generally only a metal can achieve; therefore, the process is simplified and the cost is reduced. The printed matter obtained through printing using the mirror-like silver ink disclosed in the invention has excellent mirror-like effect.

Description

【Technical field】 [0001] The invention belongs to the field of ink, and in particular relates to a mirror silver ink, a preparation method thereof and a printed matter printed with the ink. 【Background technique】 [0002] Mirror silver ink is made of special metal aluminum paste and resin as the basic material, supplemented with a suitable first solvent. It is suitable for printing on the back of transparent film, and the metal mirror effect can be seen on the front. Most of the existing mirror silver ink products can only guarantee a mirror effect after printing, but when applied to the manufacturing process of in-mold labeling (IML), they cannot withstand the 200 to 300 degrees Celsius of the injection molding section. The high temperature will cause the mirror effect to be greatly weakened, and its adhesion to the substrate will also be significantly reduced. [0003] In the production process of the known mirror silver ink, the research of aluminum paste has been widely...
