AI Technical Summary

Problems solved by technology

[0004] (1) The osmotic drying and volatilization drying of vegetable oil are much smaller than those of petroleum-based mineral oil, and the drying problem will cause problems such as stickiness, poor adhesion, and poor overprinting during printing.
[0005] (2) With the increase of the vegetable oil content of the ink, the ink will appear thixotropic increase, the body bone will become tighter, and the flow will be smaller
In the actual printing situation, the balance of ink and water is not easy to control, resulting in unstable conduction and poor printing.
[0007] (4) At the same time, with the increase of vegetable oil content in the ink, the cost of raw materials is also on the rise
[0008] (5) Due to the improvement of modern printing machines, printing companies have higher and higher requirements for printing speed, but vegetable oil inks cannot meet the above requirements

Abstract

The invention relates to all vegetable oil high-speed planographic printing ink. The all vegetable oil high-speed planographic printing ink comprises the following components in parts by weight: 20-80 parts of a binder A, 0-50 parts of a binder B, 0-30 parts of a binder C, 0-10 parts of a binder D, 10-20 parts of a pigment, 1.6-12 parts of an auxiliary and 0-15 parts of a vanish, wherein the binder A, the binder B, the binder C and the binder D are respectively composed of soybean oil, dry vegetable oil, resin and / or a resin tackifier. According to the all vegetable oil high-speed planographic printing ink, vegetable oil is used for substituting petroleum base mineral oil in the traditional printing ink, and no petroleum solvent is contained, so that the all vegetable oil high-speed planographic printing ink has excellent environmental protection property; and under middle and high speed printing conditions, the all vegetable oil high-speed planographic printing ink has the advantages of good suitability, high speed, stability on a printing machine and quick drying on a piece of paper and can meet the requirement of a printing company on an increasing printing speed as the modern printing machine is improved.

Description

technical field [0001] The invention relates to an all-vegetable oil high-speed lithographic printing ink, which is a high-speed lithographic printing ink made by basically using vegetable oil instead of solvent oil extracted from petroleum. The lithographic ink can meet the high-speed printing of 10,000 to 20,000 sheets per hour, and the printing color complies with the ISO12647-2 standard. Background technique [0002] In traditional lithographic offset printing inks, it generally contains 30-60% of petroleum-based mineral oils (organic solvent oils containing aromatics). Even soybean oil lithographic inks that meet the national offset printing environmental protection standard 370 also use 20-30% of petroleum. It is mineral oil (belonging to non-aromatic organic solvent oil). In the drying process of this type of offset printing ink, these mineral oils need to be volatilized, and a large amount of organic solvents will be released into the air, thereby causing air pollut...
