Problems solved by technology

Due to the organic components in offset printing ink, the prepared ink will have a certain odor. After the ink is printed on finished products such as books, it will affect the sensory experience of users.
[0004] In view of the related technologies mentioned above, the inventor believes that the existing environment-friendly soybean oil offset printing ink still adds odor-masking agents to reduce the odor of the ink, and does not solve the odor problem of offset printing ink from the source

Abstract

The invention relates to the field of offset printing ink, and particularly discloses low-odor offset printing ink and a preparation method thereof.The low-odor offset printing ink is prepared from, by weight, 40-70 parts of binder, 10-20 parts of pigment, 10-20 parts of vegetable oil fatty acid ester, 0.4-1 part of drying agent, 0.5-2 parts of wear-resistant agent, 1-3 parts of dispersing agent and 5-15 parts of filler; the binder comprises epoxidized soybean oil, soybean oil derivatives and rosin modified phenolic resin; the offset printing ink prepared by the invention has the advantages of ultralow odor, low VOC content and good wear resistance.

Description

technical field [0001] The present application relates to the field of offset printing ink, and more particularly, to a low-odor offset printing ink and a preparation method thereof. Background technique [0002] Traditional offset printing inks for paper are composed of pigments, binders and additives. Generally, the drying method is a combination of penetration drying and oxidation crust drying. In order to prepare high-brightness and fast-fixing inks, brightly colored organic pigments and minerals are often used. The oil dissolves and dilutes the resin. Due to the migratory nature of inks, organic pigments can migrate to the surface of the printing substrate, and organic contaminants and heavy metals can be potentially harmful to consumers. And the use of mineral oil will not only pollute the atmosphere during the printing process, but also have a negative impact on the health of printing operators, and will also cause pollution to packaging products. Especially for foo...
