Stereoscopic offset printing ink prepared by using waste vegetable oil foots as well as preparation method and application of stereoscopic offset printing ink

Abstract

The invention discloses stereoscopic offset printing ink prepared by using waste vegetable oil foots. The stereoscopic offset printing ink is prepared from the following raw materials: linolin, fatty acid methyl ester, a rosin modified phenolic resin, a dimer acid polyamide resin, a modified alkyd resin, aluminum gel, pigments, fillers and wax powder. The method for preparing the printing ink comprises the following steps: (1) weighing the linolin, rosin modified phenolic resin, dimer acid polyamide resin, modified alkyd resin and fatty acid methyl ester, raising the temperature until the resins are dissolved, raising the temperature again, and preserving the heat, thereby obtaining a resin linkage material; and (2) adding the pigments, fillers and aluminum gel, uniformly dispersing, grinding, adding the wax powder, and uniformly dispersing. The waste vegetable oil foots are taken as raw materials, the fatty acid methyl ester, is prepared, the wastes are changed into valuable materials, and the waste vegetable oil foots serve as solvents, so that the problems of plant oil base printing ink are solved. Meanwhile, an alkyd resin is synthesized by taking the waste vegetable oil foots as raw materials, the formula is adjusted, the drying speed of the printing ink is controlled, and the printing ink can be used for paper printing and film printing.

Description

technical field [0001] The invention relates to a three-dimensional offset printing ink prepared from waste vegetable oil residues, a preparation method and application thereof. Background technique [0002] With the dwindling of oil resources and the worsening of global environmental problems, traditional mineral oil-based offset printing inks are increasingly being impacted due to their high VOC emissions and many problems in printing adaptability. Pure vegetable oil ink has become an ideal substitute for traditional ink because of its excellent environmental protection performance and good printing adaptability. However, so far, among the world's mainstream ink manufacturers, except Japan's CIC and TOYO, and the United States' Sunchemical and other large ink manufacturers who have mastered the production technology of pure vegetable oil inks, most of the soybean oil inks produced by other companies are actually only Contains a small amount of soybean oil as a diluent, an...

Problems solved by technology

Traditional printed matter does not have a three-dimensional effect. Although stencil screen printing was used to obtain a three-dimensional printed matter, it has not been able to achieve this goal through lithographic offset printing.
