Problems solved by technology

Water-based ink, also called water-based ink, refers to a volatile and dry ink that uses water and a small amount of alcohol as the main solvent medium. However, due to the difficulty in overcoming the problem of ink printing dryness, about 30% of organic solvents still need to be added to water-based ink, otherwise The drying speed after printing is extremely slow, which may easily cause problems such as reverse printing of printed matter

preparation example 1

[0035] A kind of vegetable oil for high stability printing ink, its preparation method is as follows:

[0036] Take 20kg of castor oil into the reactor, heat up to 55±2°C, add 6kg of maleic anhydride, stir at 60r / min for 5min, then add 0.5kg of CaO-ZrO 2 The catalyst was reacted for 2 hours, and the filtrate was filtered to obtain esterified modified castor oil. Weigh 9kg of esterified modified castor oil, 3kg of linseed oil and 3kg of palm oil into a stirring tank, stir and disperse evenly to obtain final product.

[0038] A kind of vegetable oil for high stability printing ink, its preparation method is as follows:

[0039] Take 20kg of castor oil into the reactor, heat up to 55±2°C, add 6kg of maleic anhydride, stir at 60r / min for 5min, then add 0.5kg of CaO-ZrO 2 The catalyst was reacted for 2 hours, and the filtrate was filtered to obtain esterified modified castor oil. Weigh 6kg of esterified modified castor oil, 2kg of linseed oil and 2kg of palm oil into a stirring tank, stir and disperse evenly to obtain final product.

preparation example 3

[0041] A kind of vegetable oil for high stability printing ink, its preparation method is as follows:

[0042] Take 20kg of castor oil into the reactor, heat up to 55±2°C, add 4kg of maleic anhydride, stir at 60r / min for 5min, then add 0.5kg of CaO-ZrO 2 The catalyst was reacted for 3 hours, and the filtrate was filtered to obtain esterified modified castor oil. Weigh 7kg of esterified modified castor oil, 2.5kg of linseed oil and 2.5kg of palm oil into a stirring tank, stir and disperse evenly to obtain final product.

Abstract

The invention relates to high-stability ink and a preparation method thereof, belonging to the field of ink. The printing ink is prepared from the following raw materials: pigment, water, n-butyl methacrylate, acrylic modified alkyd resin, vegetable oil, ammonia water, an anti-reverse printing agent, a penetrating agent and a defoaming agent. The preparation method comprises the following steps: weighing the pigment, and grinding and mixing the prepared pigment; mixing the n-butyl methacrylate, the acrylic modified alkyd resin and the vegetable oil, and carrying out uniform stirring and dispersing under the protection of nitrogen to obtain a No.1 base solution; uniformly stirring and dispersing water, the anti-reverse printing agent, the penetrating agent, the defoaming agent and ammonia water to obtain a No.2 base solution; and mixing the ground pigment, the No.1 base solution and the No.2 base solution, conducting heating to 55 + / -2 DEG C under the protection of nitrogen, and carrying out uniform dispersing to obtain the ink. The ink disclosed by the invention has the advantages of low VOCs volatility, fast printing and drying, high stability and the like, and the problem that printing quality is influenced by reverse printing of ink and pigment deposition after long-time storage is not easy to occur.

Description

technical field [0001] The invention relates to the field of inks, in particular to a highly stable ink and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy, the requirements for industrial environmental protection are also increasing. In the printing industry, the volatile organic compounds (VOCs) of ink are the main environmental pollution problems. [0003] The main source of VOCs is organic solvents. In order to reduce the emission of VOCs, water-based ink has become the main type of ink used in the printing industry. Water-based ink, also called water-based ink, refers to a volatile and dry ink that uses water and a small amount of alcohol as the main solvent medium. However, due to the difficulty in overcoming the problem of ink printing dryness, about 30% of organic solvents still need to be added to water-based ink, otherwise The drying speed after printing is extremely slow, which is likely to cause prob...
