Description

A kind of ink and ink preparation method

technical field

The invention relates to the technical field of ink, in particular to an ink and an ink preparation method.

Background technique

Ink is a uniform mixture composed of colored bodies (such as pigments, dyes, etc.), binders, fillers, additives, etc.; it can be printed and dried on the printed body; it is colored and has a certain flow. Therefore, color (hue), body (rheological properties such as thinness, fluidity, etc.) and drying properties are the three most important properties of inks. There are many types of them, and their physical properties are also different. The same, some are very thick and sticky; some are quite thin, some use vegetable oil as the binder; some use resin and solvent or water as the binder. It depends on the method, the type of printing plate and the drying method.

Ink is a substance used to form graphic information in the printing process. It directly determines the tone, color and clarity of the image on the printed matter. Therefore, it plays a huge role in the printing process. At present, most of the non-stick pans have no patterns. It is because of the technical limitations of the existing inks. In recent years, a small number of products have patterns, and the methods of rolling printing, pad printing or mold spraying are used. Roll printing generally requires large batches (more than 5,000 pieces) to be produced on a large scale, and Only flat material can be printed, and pad printing must be operated by special pad printing machines and technicians. Mold spraying cannot achieve multi-color and fine patterns, nor can it be produced on curved materials. The pattern of decal transfer can be adapted. Most of the products are screen-printed on flat decals first, so the number of colors and the difficulty of printing are relatively easy, and there is no limit to the number of prints, and the transfer can be easily done without the need for technical personnel, but the inks of decals also have Certain requirements, such as fast drying speed, tough film formation, non-erosion to release paper, etc., and for different materials and usage requirements, inks must use different resins and materials to integrate with decal paper crafts and products. Therefore, it is necessary to design an ink with fast drying speed, high hardness, and wear resistance and hardness.
