Embodiment 1

[0012] An alcohol-soluble easy-to-scratch silver ink is composed of the following components in parts by mass: 25 parts of aluminum-based silver paste, 29 parts of ethanol, 29 parts of ethyl acetate, 2 parts of plasticizer, and 15 parts of nitrocellulose resin. Wherein, the plasticizer is tri-n-butyl citrate, and the nitrocellulose resin is 1 / 8 second nitrocellulose resin.

[0013] The alcohol-soluble easy-to-scratch silver ink composed of the above composition is prepared by the following steps:

[0014] 1) Weigh the materials, weigh the required parts by weight according to the formula, and set aside;

[0015] 2) To dissolve the resin, take all the nitrocellulose resin by weight, dissolve it in one-third by weight of ethanol and one-third by weight of ethyl acetate, turn on the disperser and stir evenly, and dissolve to obtain nitrocellulose resin liquid;

[0016] 3) Disperse, gradually add the nitrocellulose resin solution obtained in step 2), all the aluminum-based silve...

Embodiment 2

[0019] An alcohol-soluble easy-scratch silver ink is composed of the following components in parts by mass: 28 parts of aluminum-based silver paste, 32 parts of ethanol, 32 parts of ethyl acetate, 1.5 parts of plasticizer, and 20 parts of nitrocellulose resin. Wherein, the plasticizer is tri-n-butyl citrate, and the nitrocellulose resin is 1 / 8 second nitrocellulose resin.

[0020] The alcohol-soluble easy-to-scratch silver ink with the above components was prepared into a finished ink according to the preparation process in Example 1.

Embodiment 3

[0022] An alcohol-soluble easy-to-scratch silver ink is composed of the following components in parts by mass: 30 parts of aluminum-based silver paste, 25 parts of ethanol, 25 parts of ethyl acetate, 2 parts of plasticizer, and 18 parts of nitrocellulose resin. Wherein, the plasticizer is tri-n-butyl citrate, and the nitrocellulose resin is 1 / 8 second nitrocellulose resin.

[0023] The alcohol-soluble easy-to-scratch silver ink with the above components was prepared into a finished ink according to the preparation process in Example 1.

[0024] The quality index of alcohol-soluble easy-scratch silver ink in the above-mentioned embodiment is as follows:

Abstract

The invention discloses alcohol-soluble easily-scraped silver ink which comprises the following components in parts by mass: 22-30 parts of aluminum-based silver slurry, 25-35 parts of alcohol, 25-35 parts of ethyl acetate, 1-5 parts of plasticizing agents and 10-25 parts of nitro-cotton resin. The alcohol-soluble easily-silver-scraping ink disclosed by the invention can be suitable for film printing and intaglio printing; the high-covering-power low-brightness environmental-friendly aluminum-based silver slurry is used, so that the prepared ink has high covering power and can be not transmitted by being irradiated by adopting infrared light; after the prepared ink is printed, the ink automatically falls back without being dispersed in a powder shape after an ink layer is scraped, so that environmental friendliness is achieved; and the scraping difficulty cannot be increased with the increase of storage time, so that good usability is achieved.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to an alcohol-soluble easy-scratch silver ink. Background technique [0002] Due to the rapid development of the modern economy and today's increasingly rich spiritual and cultural life, it has become a trend to pursue luxurious and high-end products with unique performance and green environmental protection. In recent years, various functional pigments with special effects have been highly valued. Aluminum-based silver paste is a pigment made of aluminum powder through a special surface treatment process and corresponding solvents. It can reflect visible light and appear silvery white, making it have good decorative and covering properties. However, the easy-to-scratch silver inks of the prior art are generally not stable enough in performance, not convenient and thorough in scraping off, or the production process is complicated, and the production process and raw materials are not e...
