Problems solved by technology

However, due to foreign restrictions on high technology, the domestic development of weak solvent inkjet inks has been restricted.
In China, almost all of them rely on imported inks to meet market demand. Due to their high price, long transportation period, and difficulty in mass production, this results in high cost of use; while domestic weak-solvent inkjet inks have clogging during use, color Incorrect, not environmentally friendly and other technical problems have greatly affected the user's work efficiency

Abstract

The invention relates to ink-jet ink and particularly relates to weak-solvent ink-jet ink for an industrial piezoelectric jetting head and a preparation method thereof. The weak-solvent ink-jet ink contains the following ingredients in percentage by weight: 1-5% of organic pigment, 1-5% of humectant, 1-10% of macromolecular polymer resin, 1-10% of quick drying agent, 1-10% of solvency promotor, 0.1-2% of wetting agent, 0.1-40% of dispersing agent, 0.01-2% of performance modifier and the balance of environmental-friendly weak solvent. The preparation method of the weak-solvent ink-jet ink for the industrial piezoelectric jetting head comprises the steps of preparing color paste and preparing a finished product. According to the weak-solvent ink-jet ink for the industrial piezoelectric jetting head, the weak-solvent ink-jet ink is environmental-friendly and is harmless to human bodies, the particle diameter can reach a nanoscale, the smoothness performance is excellent, and jetting holes of a printer can not be blocked; the preparation method of the ink is simple, is relatively low in cost and is applicable to batch production, and no difference exists among batches.

Description

technical field [0001] The invention relates to an ink-jet ink, in particular to a weak-solvent ink-jet ink for industrial piezoelectric nozzles and a preparation method thereof. Background technique [0002] There are two types of inkjet inks on the market: one is pigment-based inkjet ink; the other is dye-based inkjet ink; the advantages of pigment-based inkjet ink are outdoor waterproof, light-resistant, and the printed image is saturated and bright in color and has a strong texture. Mainly used for printing outdoor advertising screens. The advantage of dye-based inkjet ink is that it can restore the true color of the image and has high precision. However, the disadvantage of dye-based inkjet ink is that it is not waterproof, not light-resistant, and it is not easy to store images for a long time, so it is suitable for indoor image production. [0003] With the rapid development of inkjet printing technology and the increasing social awareness of environmental protection...
