Embodiment 1

[0035] The formula of water-based gold ink is as follows:

[0036]

[0037] Prepare water-based gold ink as follows:

[0038] 1) Weigh the water-based color paste, water-soluble acrylic resin, dispersant, additives and water according to the formula ratio and grind them finely; during the fine grinding process, the temperature is 60°C, the pH value is 7.0, and the grinding time is 3 hours;

[0039] 2) Mix the raw materials and stir evenly, first add 50% of the polymerization initiator, then raise the temperature under stirring, add the remaining polymerization initiator in batches during the heating process; the total amount of the polymerization initiator added is 0.3%;

[0040] 3) Reaction under reflux conditions for 1.5 hours;

[0041] 4) Focus on controlling the viscosity of the polymer. The viscosity is 160 seconds / 25°C in the No. 4 cup, and the acid value is 45 mgkoh / g. Add ammonia solution for neutralization, and control the final pH value to 8.0;

[0042] 5) Dilut...

Abstract

The invention relates to the field of tobacco preparation, in particular to a water-based gold ink for tipping paper and a preparation method thereof. The water-based gold ink comprises the following raw materials in parts by weight: 60-65 parts of water-based color paste, 10-16 parts of water-soluble acrylic resin, 10-15 parts of a dispersing agent, 10-30 parts of water and 0.5-1 part of additive. Compared with the prior art, through the utilization of a special formula and processing process, the problem that the water-based gold ink becomes aeruginous due to oxidation reaction is solved, the printing fastness of the water-based gold ink is also improved, the printing effect can reach or exceed the effect of a conventional solvent type gold ink, and the gold ink has a very big practical application value.

Description

technical field [0001] The invention relates to the field of tobacco preparation, in particular to a special water-based gold ink for tipping paper and a preparation method thereof. Background technique [0002] Cigarette tipping paper is currently generally used for surface gravure printing with organic solvent-based inks, so that the surface of the currently used tipping paper contains a lot of organic volatile residues, such as benzene series, esters, ethers, and ketones; the above substances It will enter the human body through direct contact with the mouth of cigarette smokers, causing certain potential hazards. At the same time, due to the use of solvent-based inks, the printing process will inevitably bring about a large amount of volatilization of organic solvents, which will generate a large amount of VOC emissions to the working environment and the surrounding atmosphere, causing certain environmental pollution, and the application of water-based inks can greatly r...
