Problems solved by technology

[0007] However, although water-based ink has many advantages and is in line with the development trend of safety and environmental protection, its development in China is still very slow. This is because it still has many shortcomings, among which low peel strength and poor bonding stability are the most important. This will cause the ink to fall off easily, which will affect the use effect of the product

Abstract

The invention discloses anti-dropping ink. The anti-dropping ink is prepared from the following raw materials in parts by weight: 10 to 20 parts of biphenol-A modified phenolic resin, 1 to 2 parts oftert-butyl-p-diphenol, 0.4 to 1 part of polysorbate, 0.1 to 0.2 part of barium naphthenate, 4 to 5 parts of nano silicon dioxide, and 3 to 5 parts of stearic acid. By adopting the anti-dropping ink, the dispersion compatibility between the nano silicon dioxide and the phenolic resin can be realized, the mechanical performance of the ink can be improved, the added phenolic resin has good viscosity,and the anti-dropping performance of a finished product can be effectively improved.

Description

technical field [0001] The invention belongs to the field of inks, and in particular relates to an anti-shedding ink and a preparation method thereof. Background technique [0002] Water-based ink uses water as a dissolution carrier, which has advantages different from other inks. Its main characteristics are manifested in the following four aspects; [0003] Does not pollute the atmosphere: less VOC emissions. In water-based ink, water exists as the main solvent, with a small amount of alcohol added, so almost no volatile organic gases (VOC) are emitted into the air, causing pollution to the atmosphere. [0004] Reduce residual toxic substances on the surface of printed matter. In water-based ink, water exists as the main solvent, and a small amount of alcohol is added. After the printed water-based ink dries, the water and alcohol will volatilize into the air, so there will be no toxic organic residues in the printed matter, ensuring Hygienic safety of printed matter. ...
