Problems solved by technology

Usually ink printing is carried out under continuous high-speed operation. The ink transferred to the printing paper cannot be dried immediately, and the printed matter is easy to stick when stacked together, resulting in dirty and sticky pages on the back, which affects the quality of the printed matter.
[0003] Although many fast-fixing inks have been developed at present, it is intended to accelerate the initial solidification of the ink by means of the physical changes of the ink

Abstract

The invention provides a printing ink composition containing starch. 2 to 2.5 weight parts of starch of which the fineness is 8 to 12 microns is added into 100 weight parts of printing ink; and the printing ink containing starch comprises the following components in percentage by weight: 9 to 15 percent of pigment, 40 to 45 percent of ester gum, 4 to 8 percent of acrylic resin, 18 to 20 percent of linseed oil or soybean oil, 20 to 25 percent of isopropanol and ethyl acetate mixture, and 3 to 8 percent of aid. Due to the adoption of the technical scheme, the obtained printing ink composition can effectively accelerate the drying speed of ink, solve the problems that printing matters are adhered to each other, and ensure that a printer has a normal printing speed; a product can be dried completely, and the phenomenon of set-off and the phenomenon that the products are adhered to be dimmed can be avoided; the product is high in glossiness; and the printing ink composition has the advantages of simple component, convenience in preparation and obvious effect.

Description

technical field [0001] The invention belongs to the field of printing inks, in particular to a printing ink composition containing starch. Background technique [0002] The problem of staining of printed matter has always been a difficult problem in ink printing. Usually, ink printing is carried out under continuous high-speed operation. The ink transferred to the printing paper cannot be dried immediately, and the printed matter is easy to stick when stacked together, resulting in dirty and sticky pages on the back, which affects the quality of the printed matter. [0003] Although many fast-fixing inks have been developed at present, it is intended to accelerate the initial solidification of the ink by means of the physical changes of the ink and the paper itself, so as to support the successive piles of paper and slight dragging during printing, but the problem has not yet been completely solved. solve. At present, the commonly used method is still to spray a layer of p...
