Alcohol-soluble silk-screen printing ink

Abstract

The invention relates to alcohol-soluble silk-screen printing ink. The alcohol-soluble silk-screen printing ink is prepared from the following raw materials in parts by weight: 15-20 parts of pigment, 45-55 parts of binder, 25-32 parts of anhydrous ethanol, 0.5-0.8 part of alum, 0.2-0.5 part of turpentine, 0.5-1 part of pentaerythritol, 0.5-1 part of alkyl modified organic siloxane and 1-2 parts of oleamide, wherein the binder is prepared from the following raw materials in parts by weight: 20-24 parts of polyester resin, 15-20 parts of polyvinyl butyral resin, 10-20 parts of acrylic resin, 15-20 parts of amino resin, 20-35 parts of anhydrous ethanol and 30-40 parts of titania. The ink disclosed by the invention can be degraded in alcohol solvents, is environmental-friendly and pollution-free, is strong in adhesion, good in wear resistance and high in glossiness, and is applicable to 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...
