Abstract

The invention discloses printing ink and a preparation method thereof. The printing ink is prepared from raw materials in parts by weight as follows: 90-100 parts of deionized water, 4-6 parts of dye, 1-3 parts of a nonionic surfactant, 14-16 parts of glycerin, 4-6 parts of ethylene glycol, 3-5 parts of ethanol, 0.8-1.2 parts of benzoic acid, 1-3 parts of a preservative and 4-6 parts of an anti-blocking agent; the anti-blocking agent is a mixture of octyl palmitate and methyl acrylate in the weight ratio being (3-5):1. The printing ink is low in cost and doesn't easily block an inkjet head. The preparation method of the printing ink is simple and the printing ink can be self-prepared with simple equipment.

Description

technical field [0001] The invention belongs to the field of printing consumables, and in particular relates to a printing ink and a preparation method thereof. Background technique [0002] Printing ink, also known as printing oil, is mostly thick liquid. It can be divided into two categories: (1) water-based printing ink, using water as a solvent, using water-soluble dyes plus glycerin and gum arabic, etc., suitable for rubber printing and wood printing; (2) oil-based printing ink, using non-drying oil as a solvent , made with oil-soluble dyes or pigments, suitable for metal printing. [0003] At present, the biggest problem with using printing ink is that the ink is easy to clog the inkjet head, and the price of ink with good anti-clogging effect is too high. The market urgently needs low-cost inks that are not easy to clog inkjet heads. Contents of the invention [0004] The object of the present invention is to provide a printing ink and a preparation method thereo...
