Abstract

The invention relates to the field of tobacco preparation, particularly to a special aqueous gold ink for tipping paper, a preparation method and an application thereof. The special aqueous gold ink comprises the following raw materials, by weight: 25-30 parts of bronze powder, 35-48 parts of alcohol-waterborne polyurethane, 15-25 parts of ethanol, 10-25 parts of water, and 0.5-1.5 parts of coconut oleic acid amide. The present invention further provides a preparation method and an application of the special aqueous gold ink. Compared with the special aqueous gold ink in the prior art, the special aqueous gold ink of the present invention has the following characteristics that: with the special formula and the treatment process, the problem that the aqueous gold ink contacts water to carry out an oxidation reaction so as to change into the aerugo is solved, the printing fastness of the obtained aqueous gold ink is improved, the printing effect of the aqueous gold ink can achieve or exceed the printing effect of the currently-used solvent type gold ink, and great practical application values are provided.

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 its preparation method and application. 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...
