Abstract

The invention relates to a process for processing ink for printers, comprising the steps of: uniformly mixing the following components according to parts by weight, and then passing through a 0.02 micron filter to obtain a finished product: 10-30 parts of black dye, 1-5 parts of ethylene glycol, 2-8 parts of alkoxylated alcohol, 1-6 parts of polyethylene glycol, 5-7 parts of sodium bicarbonate, 1-3 parts of sodium fatty alcohol ether sulfate, 1-3 parts of pyrrolidone, 2-5 parts of polyacrylic acid Ester emulsion, 1‑3 parts dipropylene glycol ether, 100‑150 parts deionized water. The ink prepared by the invention has good stability, and no flocculation and precipitation will occur after being placed for a long time.

Description

technical field [0001] The invention relates to a printing ink processing technology. Background technique [0002] According to the applicant's knowledge, the ink used in the black ink cartridge of the existing inkjet printer has stability problems, and flocculation and precipitation will occur after long-term storage, resulting in blockage of the nozzle of the ink cartridge. Contents of the invention [0003] In order to solve the problems existing in the prior art, the invention provides a method for preparing ink for ink-jet printer black ink cartridges [0004] method, the prepared ink has good stability, and no flocculation and precipitation will occur after long-term storage. [0005] The printing ink processing technology of the present invention comprises the following steps: [0006] Mix the following components uniformly according to parts by weight, and pass through a 0.02 micron filter to obtain the finished product: [0007] 10-30 parts black dye, 1-5 part...
