Problems solved by technology

[0003] However, for the instant lottery ink imported from abroad, after the printing is completed, the tape fastness test sometimes fails in the safety performance. If there is no off-machine test, the safety performance testing personnel will not be able to accurately judge whether it is the ink of this batch or the working condition of the machine, which will easily cause downtime and reduce production efficiency

Embodiment 1

[0023] A kind of scratch-off white ink that solves the problem of poor fastness of the instant lottery scratch-off ink machine tape, comprising the following components in parts by weight: titanium dioxide 30, acrylic resin 18, pure propanol liquid 10, dispersant 4, slip agent 2. Deionized water 28, the solid content of pure propanol liquid is 49%.

[0024] The preparation method of the above-mentioned scratch-off white ink that solves the poor fastness of the instant-open lottery scratch-off ink machine tape:

[0025] 1) Weigh titanium dioxide, acrylic resin, pure propanol liquid, dispersant, smoothing agent, deionized water, mix, and stir at a high speed to obtain a mixture by weight; the stirring time of mixing and stirring is 40-50min, and the stirring speed is 800-1200r / min;

[0026] 2) Determination of product inspection after passing the package.

Embodiment 2

[0028] A scratch-off white ink that solves the poor fastness of the instant lottery scratch-off ink machine tape, comprising the following components in parts by weight: titanium dioxide 50, acrylic resin 26, pure propanol liquid 5, dispersant 6, slip agent 4. Deionized water 15, the solid content of pure propanol liquid is 61%.

[0029] The preparation method is the same as in Example 1.

Embodiment 3

[0031] A kind of scratch-off white ink to solve the problem of poor fastness of the instant lottery scratch-off ink machine tape, comprising the following components in parts by weight: titanium dioxide 35, acrylic resin 24, pure propanol liquid 8, dispersant 5.5, slip agent 2.5, deionized water 20, the solid content of the pure propanol solution is 49%.

[0032] The preparation method is the same as in Example 1.

Abstract

The invention discloses scraping white ink for solving the problem of poor off-machine adhesive tape fastness of scraping ink of an instant lottery ticket. The scraping white ink comprises the following components in parts by weight: 30-50 parts of titanium dioxide, 18-26 parts of acrylic resin, 5-10 parts of pure propanol liquid, 4-6 parts of a dispersing agent, 2-4 parts of a slipping agent and15-28 parts of deionized water, wherein the solid content of the pure propanol liquid is 49-61%. According to the scraping white ink, on the premise that scraping white and even other properties of the whole scraping layer are not affected, the instantaneity problem of the adhesive tape fastness of the scraping layer is effectively solved; and compared with foreign imported products, the off-machine instant adhesive tape fastness of the scraping white ink in the invention is obviously improved, and the off-machine adhesive tape fastness of the scraping white ink after ink printing is basicallyat the fourth level or above.
