Problems solved by technology

Although large-format color inkjet printers are equipped with the original ink of the manufacturer when purchasing, and imported original ink is also available in the later use, but its price is expensive, causing higher costs to users
In recent years, although the variety of digital inkjet inkjet inks is increasing, some of the existing digital inkjet inkjet inks are darker in color, easy to fade, poor in stability, easy to spread pictures, easy to wrinkle paper, and easy to clog the nozzles. Recycled filling, with a strong smell, causing certain harm to the human body

Abstract

The invention relates to digital printing inkjet ink, which is prepared by the following materials: pigment (red / yellow / blue / black), sodium dodecyl benzene sulfonate, N n-dimethylformamide, 1.2-propylene glycol, polyvinylpyrrolidone K30, deionized water. The invention relates to a preparation method of the digital printing inkjet ink, which includes the following steps: the pigments, sodium dodecyl benzene sulfonate and 1.2-propylene glycol are respectively weighed, and put in container A, stirred, and mixed evenly; deionized water and polyvinylpyrrolidone K30 are respectively weighed, and deionized water and polyvinylpyrrolidone K30 accounting for 10 percent of the total weight are put in container B, and heated and stirred until the two materials are completely dissolved, and then are put in the container A, and stirred and mixed evenly; N n-dimethylformamide is weighed, and the weighed N n-dimethylformamide and the residual deionized water are put in the container A, and are stirred, placed statically and filtered to produce the finished product. The digital printing inkjet ink applies to different models of machines, and is material saving and convenient; the colors are rich, beautiful and stable, and are strongly coated without plugging; the spraying is mellifluent; the character strokes in pictures do not proliferate, the paper is not easily wrinkled, the fastness is high, the product is ultraviolet radiation resistant, and the images can be reserved for fifty years without fading.

Description

technical field [0001] The invention relates to a stationery product, in particular to a digital inkjet inkjet ink and a preparation method of the digital inkjet inkjet ink. Background technique [0002] With the development of society, all kinds of color inkjet printers have been rapidly developed and widely used. They are popular with users for their fast, efficient, and high-quality features, and have been widely used in the advertising industry. However, the selection of its consumable inkjet inkjet ink has become the main problem that plagues the industry. Although the large-format color inkjet printers are equipped with the original ink of the manufacturer when purchasing, and imported original ink is also available in the later use, but its price is expensive, causing higher costs to users. In recent years, although the variety of digital inkjet inkjet inks has been increasing day by day, some of the existing digital inkjet inkjet inks are darker in color, easy to fa...
