Abstract

The invention relates to an alcohol-soluble letterpress ink which is prepared from the following raw materials in parts by weight: 15-25 parts of pigment, 35-40 parts of binder, 15-18 parts of barium sulfate, 20-30 parts of anhydrous ethanol, 1-2 parts of TX-9, 1-3 parts of tridecanol, 1-2 parts of di-n-butyltin dilaurate and 0.5-1 part of vaseline. The binder is prepared from the following raw materials in parts by weight: 25-28 parts of polyvinyl butyral resin, 7-13 parts of acrylic acid monomer, 3-7 parts of phenol aldehyde resin, 4-7 parts of tung oil, 40-45 parts of anhydrous ethanol, 5-7 parts of nitrocellulose solution and 0.5-1.5 parts of paraffin. The ink can be degrade in an alcohol solvent, has the advantages of environmental protection, no pollution, high adhesive force, favorable wear resistance and high glossiness, and is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of printing ink, in particular to a green and environment-friendly ink formula. Background technique [0002] With the continuous improvement of people's quality of life and living environment, people's requirements for energy-saving, low-consumption, non-toxic, non-polluting, and easily degradable products are getting higher and higher, and printing ink is one of the most polluting materials. Solvent-based printing inks contain a large number of toxic and harmful chemicals, including heavy metals, residual solvents, organic volatiles, and polycyclic aromatic hydrocarbons. These toxic and harmful substances can send chemical transfer, so that people are contaminated with toluene, xylene, lead, mercury, arsenic, chromium and other harmful substances in life, work and study. At present, environmentally friendly inks represented by water-based inks, alcohol-soluble inks, and UV inks are increasingly favored by...
