Biodegradable color printing ink auxiliary

Abstract

The invention discloses a biodegradable color printing ink auxiliary which comprises the following main raw materials in parts by weight: 5-10 parts of menthol, 2-6 parts of glaucocalyxin, 17-22 parts of hasmanine, 20-30 parts of 13-dehydroxyindaconintine, 8-17 parts of gomisin G, 15-25 parts of rhoifolin, 11-14 parts of scopolin, 5-9 parts of 2-chlorin-6-fluorophenol, 7-12 parts of chloromethyl methyl ether, 0.5-0.8 part of boron trifluoride methyl alcohol, 2-4 parts of pentobarbital sodium salt, 2-4 parts of 2-aminophenol-4-(2-carboxyl) sulphonanilid and 2-4 parts of cis-dichloride (diethyl sulfide) platinum. The biodegradable color printing ink auxiliary has the advantages of environmental protection, harmless effect, high safety, stable property and good printing effect. When the wastes are recycled, under the effect of a decolorizing agent, the ink can be quickly decolorized, the problem of volatilization of the organic solvent in the oil-based ink can be eliminated and the problems of high deinking difficulty of wastepaper and serious sewage discharge can be solved.

Description

technical field [0001] The invention relates to the field of preparation of ink additives, in particular to a biodegradable color printing ink additive. Background technique [0002] With the development of social culture, science and technology, and economy, the printing industry is developing at an unprecedented speed, and ink is the biggest source of pollution in the printing industry. Traditional oil-based inks use organic solvents such as aromatic hydrocarbons, esters, and ketones as solvents. The content of organic solvents in inks is generally 50%-70%. Most of these solvents will volatilize during the printing process, which seriously pollutes the environment and directly harms human health. The solvent used in water-based ink is mainly deionized water, which can greatly reduce the emission of volatile organic solvents (VOC) and reduce air pollution. Therefore, the research and development of water-based ink is becoming the mainstream of the printing industry. Howev...

Problems solved by technology

However, in the current research and development of water-based inks, people only pay attention to the printing process of the ink, emphasizing the strong adhesion and no decolorization, completely ignoring the deinking process during waste paper recycling, resulting in deinking during waste paper recycling. The ink is difficult and the process is complicated

Not only pollute the environment due to the discharge of sewage, but also affect the recycling rate of waste paper due to the difficulty of deinking, which greatly wastes resources
