Problems solved by technology

[0002] At present, most of the color jet printing inks used for ink cartridge filling in the market are dyes, which are poor in light resistance and water resistance. The clogging of the holes greatly reduces the life of the nozzle; it is difficult to describe the delicate details in the pattern, and the color level and transition are also difficult to achieve the expected effect; the quality of inkjet printing cannot be guaranteed, or even cannot be printed at all; secondly, the pH value and conductivity of the ink are unstable. It is easy to corrode and damage the internal parts of the printer, pollute the environment, and cause damage to the health of users

[0024] Preparation method, the steps are as follows:

[0025] 1) Take each component in proportion, stir and mix the colored nano light fast dye with deionized water to form a uniform color paste;

[0026] 2) Under stirring conditions, heat the color paste to 60-70°C and keep the temperature constant for 1.5-2 hours;

[0027] 3) Cool the color paste to normal temperature, add ethylene glycol, absolute ethanol and glycerin, and stir evenly;

[0028] 4) Put it into a multi-stage filter, and filter it at least three times under a pressure of 1.5-2Kg to obtain a color jet printing ink.

Embodiment 1、2

[0029] Examples 1 and 2, the color paste was heated to 60°C, kept at a constant temperature for 2 hours, and filtered three times under a pressure of 1.5Kg.

Embodiment 3

[0030] Examples 3 and 4, the color paste was heated to 70°C, kept at a constant temperature for 1.5 hours, and filtered three times under a pressure of 2Kg.

Abstract

The invention discloses a method to manufacture colorful jet printing ink that includes the constituent of color nm light resistance dye 3.5-7.5 portions, deionized water 55-66 portions, ethylene glycol 1.5-4 portions, anhydrous alcohol 15-20 portions and glycerin 2-3 portions. It has the features of water endurance, light endurance, no-precipitation and fastness. It could be widely used in kinds of different series of jet printer.

Description

technical field [0001] The invention relates to a color jet printing ink and a preparation method thereof. Background technique [0002] At present, most of the color jet printing inks used for ink cartridge filling in the market are dyes, which are poor in light resistance and water resistance. The clogging of the holes greatly reduces the life of the nozzle; it is difficult to describe the exquisite details in the pattern, and the color level and transition are also difficult to achieve the expected effect; the inkjet printing quality cannot be guaranteed, or even cannot be printed at all; secondly, the pH value and conductivity of the ink are unstable, It is easy to corrode and damage the internal parts of the printer, pollute the environment, and cause damage to the health of users. Contents of the invention [0003] The object of the present invention is to provide a color jet printing ink with excellent performance and a preparation method thereof. [0004] The col...
