Problems solved by technology

With the continuous expansion of the application field of digital inkjet, the corresponding increase in scale, the demand for screen diversity, and the faster and faster printing speed of the machine, the drying time of the screen is getting shorter and shorter, which leads to the current use of inkjet. The ink can not dry well on the medium, and the mucous membrane is not tight, which affects the production speed. At the same time, the screen is polluted and scrapped due to the slow drying time of the screen.
[0003] Publication number is that the Chinese patent of CN 1386802A discloses quick-drying inks for inkjet printers, which includes adding specific proportions of short-chain alcohols and oligomers and / or polymers in the ink composition, but due to the The quick-drying ink for inkjet printers achieves the purpose of quick-drying by reducing alcohols in the ink composition. This ink can no longer meet the needs of today's high-speed printers, and today's advertising screens use color inkjet inks, printing media Nor is the paper mentioned in the patent

Abstract

The invention discloses a high-concentration quickly-dried digital ink-jet ink and a preparation method thereof. The high-concentration quickly-dried digital ink-jet ink is composed of the following components by weight percent: 20-40% of liquid dye, 20-40% of a viscosity modifier, 0.1-2% of a surfactant, 0.1-2% of a pH value adjusting agent, 0.01-1% of an antiseptic bactericide and the balance of de-ionized water. When ink provided by the invention is used for printing in a machine, a smaller amount of ink can meet requirements of a screen and reach bright color; meanwhile, the amount of the high-concentration ink printed on paper is low, so that the contained solvent components are fewer, to greatly increase the evaporation speed of the solvent on the paper, thereby achieving the purpose of quickly drying; even in case of today's advertising paper coating being thinner and thinner, the problems of mess-up screen and loose adhesive film can also be solved, so as to improve the printing quality and reduce the scrap of screens.

Description

technical field [0001] The invention relates to the field of inks for large-format printers, and more specifically relates to a high-concentration fast-drying digital inkjet ink and a preparation method thereof. Background technique [0002] In recent years, digital inkjet has become the first choice for advertising in all walks of life due to its advantages of no need for plate making, instant printing, bright colors, high picture precision, and environmental friendliness. With the continuous expansion of the application field of digital inkjet, the corresponding increase in scale, the demand for screen diversity, and the faster and faster printing speed of the machine, the drying time of the screen is getting shorter and shorter, which leads to the current use of inkjet. The ink cannot dry well on the medium, and the mucous membrane is not tight, which affects the production speed. At the same time, the screen is polluted and scrapped due to the slow drying time of the scr...
