Problems solved by technology

As the requirements for environmental protection are getting higher and higher, the traditional quick-drying glossy inks are becoming less and less suitable for environmental protection requirements. Although high-boiling kerosene has been changed from high-aromatic kerosene to low-aromatic or even aromatic-free kerosene in recent years, kerosene is ultimately It is a petrochemical product and a non-renewable resource
The environmentally friendly offset printing inks currently on the market use a large amount of dry vegetable oil and semi-dry vegetable oil instead of high-boiling kerosene for environmental protection, sacrificing the fixing performance of the ink, and cannot meet the requirements of modern high-speed printing.

Abstract

The invention discloses quick-dry high-gloss environment-friendly offset printing ink which is prepared from the following components in percentage by weight: 55 to 65 percent of environment-friendly bonding material, 20 to 28 percent of pigment and filler, 0 to 5 percent of alkyd resin, 0 to 5 percent of vegetable oil, 0 to 1 percent of dispersing agent, 0 to 2.5 percent of drier, 0 to 2 percent of wax and 5 to 10 percent of vegetable oil fatty acid ester, wherein the environment-friendly bonding material is prepared from the following components in percentage by weight: 35 to 45 percent of rosin modified phenolic resin, 20 to 40 percent of vegetable oil, 10 to 30 percent of vegetable oil fatty acid ester and 0 to 2 percent of gel. The quick-dry high-gloss environment-friendly offset printing ink disclosed by the invention has an identical or higher setting speed in comparison with that of general quick-dry high-gloss ink, is excellent in glossiness and is free from VOC (Volatile Organic Compounds); due to the use of a large amount of renewable resource, the quick-dry high-gloss environment-friendly offset printing ink is excellent in environment protection.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to an environmentally friendly offset printing ink. Background technique [0002] The drying form of traditional offset printing ink is a mixed drying form combining osmotic fixation and oxidative polymerization: the ink is printed on the paper, first the solvent penetrates into the capillary pores of the paper, the resin is precipitated and fixed, and then the dry vegetable oil in the binder and Its chain polymer is oxidized and cross-linked into a network structure macromolecule, which is cured to form a solid ink film. The dry vegetable oils in traditional offset printing inks are mostly dry vegetable oils such as linseed oil, catalpa oil, and tung oil, and the dilution solvent is kerosene with a high boiling point, and the distillation range is between 270 and 320°C. As the requirements for environmental protection are getting higher and higher, the traditional quick-drying glossy...
