Embodiment Construction

[0023] The formula of the embodiment of the invention is referring to Table 1:

[0024] Table 1: (unit: weight percentage)

[0025]

[0026] According to above-mentioned prescription, preparation method carries out as follows:

[0027] (1) Stir the carbon black slurry produced by Kunshan Shiming Company at a speed of 1000-2000r / min, and slowly add polymer latex and adsorption accelerator during the stirring process; gradually increase the stirring speed to 2000-4000r / min, The continuous stirring time is not less than 60min, and the latex adsorption type carbon black slurry is obtained.

[0028] (2) Stir the latex adsorption type carbon black slurry obtained in step (1) at a speed of 1000 to 2000r / min, and slowly add a thickener, a defoamer and a surplus of deionized water during the stirring process. Stirring is continued for 30 minutes after the thickener to obtain latex adsorption type carbon black pigment pseudoplastic color paste.

[0029] (3) Filtrate the latex adso...

Abstract

The invention discloses emulsion absorption black gel ink and a preparation method of the gel ink. The gel ink is composed of carbon black paste, polymer emulsion, absorption accelerator, functional assistant, thickening agent, defoaming agent and deionized water; the raw materials are proportioned according to the total weight percents as follows: 10.0-40.0 percent of the carbon black paste, 2.0-20.0 percent of the polymer emulsion, 0.1-0.5 percent of the absorption accelerator, 10.0-30.0 percent of the functional assistant, 0.5-10.0 percent of the thickening agent, 0.1-0.2 percent of the defoaming agent and the rest percent of the deionized water. The emulsion absorption black gel ink prepared in the invention has the advantages of higher color depth in writing, good hand feel and good glossiness, keeping unchanged writing performance after being stored for 12 months under normal temperature, applying to industrial production, and having significant commercial value.

Description

technical field [0001] The invention relates to a black neutral ink, in particular to a latex absorption type black neutral ink and a preparation method thereof. Background technique [0002] The full name of neutral ink is "water-based pigment medium viscosity ink". The so-called neutral ink means that its viscosity is between the oily ballpoint pen ink and the water-based ballpoint pen ink. Neutral inks use water and water-soluble solvents as dispersion media, and use rheology modifiers to provide ink pseudoplasticity. Pseudoplasticity means that the viscosity of the ink is very high under static conditions, and the ink cannot flow. Under the action of shearing, the viscosity of the ink becomes smaller, reflecting flowability. Neutral ink has the advantages of both oil-based ballpoint pens and water-based ballpoint pens. The neutral ballpoint pen writes fluently and feels light. At the same time, after the ink is transferred to the writing material, it has a high viscos...
