Embodiment 1

[0041] The raw material formula of water-based ink is as follows:

[0042]

[0043] The 60% iron oxide color paste and 60% titanium dioxide powder paste in the formula can be prepared as follows:

[0044] Wash 58.2 parts by weight of iron oxide or titanium dioxide, adjust the pH value to 7.0-7.5, centrifuge and dehydrate to form a filter cake with a solid content of 81%, add coupling agent, 21 parts of ammonia with a solid content of 20% Mix acrylic resin aqueous solution and 16.49 parts of water, stir, add 0.345 parts of defoamer during stirring, and then grind to an average particle size of 1-3 μm; wherein, the amount of coupling agent added is 5% of iron oxide or titanium dioxide -6% (percentage by weight).

[0045] Then prepare water-based ink as follows:

[0046] (1) Weigh the above components according to the formula ratio and grind them finely; during the fine grinding process, the temperature is 55°C, the pH value is 7.0, and the grinding time is 3 hours;

Embodiment 2

[0052] The raw material formula of water-based ink is as follows:

[0053]

[0054] Prepare water-based ink as follows:

[0055] (1) Weigh the above components according to the formula ratio and grind them finely; during the fine grinding process, the temperature is 65°C, the pH value is 7.0, and the grinding time is 5 hours;

[0056] (2) Mix the materials obtained in step (1) evenly, add 50% benzoyl peroxide while stirring, and then gradually increase the temperature;

[0057] (3) When the temperature rises to 130°C, start to keep warm, and add the remaining benzoyl peroxide in batches, the total amount of benzoyl peroxide added is 0.2% of the total amount of each raw material component in step (1), Reflux and heat preservation for 1.5 hours; reflux heat preservation until the viscosity is 170 seconds / 25°C according to the No. 4 cup, and the acid value is 50 mgkoh / g;

[0058] (4) Cool down to 70°C, add ammonia water to ammonify to pH 7; then dilute with a mixture of etha...

Abstract

The invention relates to the technical field of ink, and particularly relates to special water-based ink for tipping paper as well as a preparation method and an application thereof. In the special water-based ink for tipping paper provided by the invention, the raw material comprises the following components in parts by weight: 20-30 parts of iron oxide color paste, 10-20 parts of titanium dioxide color paste, 1-5 parts of carbon black paste, 20-30 parts of water-based acrylic resin, 10-20 parts of dispersing agent, 10-20 parts of water and 0.3-0.5 part of auxiliary. Compared with the prior art, the water-based ink provided by the invention does not contain organic volatile matters and can improve the safety of the cigarette tipping paper serving as a mouth contact material without causing environmental pollution.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a special water-based ink for tipping paper and its preparation method and application. Background technique [0002] Water-based ink is referred to as water-based ink. The main difference between water-based ink and oil-based ink is the difference in solvent. Water-based ink uses water as a solvent, and the VOC (Volatile Organic Compounds, abbreviation for volatile organic compounds) content is extremely low, which pollutes the environment less; oil-based ink uses organic solvents ( Toluene, xylene, industrial alcohol, etc.) as solvents. In the flexible packaging industry, since oil-based inks are mainly volatile and dry, the lower the boiling point of the solvent, the easier it is to volatilize and release toxic gases to pollute the environment. After printing, there are residual toxic substances on the surface, while water-based inks use The solvent is water and ethanol excluded...
