Embodiment 1

[0053] This embodiment prepares a kind of scraping ink, and this scraping ink comprises the following components by weight:

[0054] Color paste: 80 parts,

[0055] Water-based resin: 50 parts,

[0056] Leveling agent: 0.05 parts,

[0057] Defoamer: 0.05 parts.

[0058] Wherein, the water-based resin is water-based acrylate or water-based polyurethane.

[0059] The leveling agent is acrylate or modified polydimethylsiloxane.

[0060] Antifoaming agents include silica-containing mineral oil type antifoaming agents.

[0061] The scraping ink also contains an appropriate amount of pH adjuster ammonia water, which adjusts the pH to a pH value of 7-8, so that the resin can be stably dispersed in the solution.

[0062] The preparation method of the scratch-off ink is as follows: in a stirring state, add water-based resin, leveling agent, defoamer and pH regulator into the color paste in sequence, and disperse evenly. The stirring speed is 500rpm, and the time is 45min.

Abstract

The invention provides scraping ink as well as a preparation method and application thereof. The scraping ink is prepared from the following raw materials: color paste, water-based resin, a leveling agent, a thickener and an antifoaming agent. According to the scraping ink, the water-based scraping ink is prepared by compounding the color paste, the water-based resin, the leveling agent, the thickener and the antifoaming agent, so that the scraping ink is green and environment-friendly, and can be suitable for various printing modes. The scraping layer obtained by printing is good in covering property, still has excellent covering property even if the thickness is as thin as 1-5 microns, and meets the national standard and cold light source irradiation requirements. Besides, the prepared scraping layer is balanced between wear resistance and easy scraping performance, and is not easy to wear and fall off in production and circulation links while being easy to scrape. When the prepared scraping layer is used for scraping, the ink is agglomerated and cannot be pulverized, and the cleaning degree is high. The performance of the scraping ink is stable, and the situation that ink is obviously difficult to scrape off due to long storage time is avoided.

Description

technical field [0001] The invention belongs to the technical field of printing inks, and in particular relates to a scraping ink and a preparation method and application thereof. Background technique [0002] Scratch ink is an ink used for scratch-off printing of scratch cards, invoices, consumer coupons, etc. The scratch-off layer is a coating that covers the graphic information on the substrate, and the covered information can be seen by scraping it off with a fingernail or a hard object. [0003] For the scratch layer, wear resistance and easy scratch off are relative and contradictory. The actual product is the result of a balance between the two indicators of wear resistance and ease of scratching. The scraping layer needs to be easy to scrape off, but not too easy to scrape off, otherwise it will be easily worn off during production and distribution; at the same time, it should not be too wear-resistant, otherwise it will be difficult to scrape off.
