Embodiment 1

[0023] The red ink for cleaning label printing in this embodiment includes 0.8% C.I. Acid Red 52, 0.7% C.I. Acid Red 289, 16% diethylene glycol, 9% triethylene glycol monobutyl ether, 0.5 % Surfactant ProxelXL2, balance deionized water.

[0024] Preparation method: mix according to the above formula, then magnetically stir at 50 ° C for 2, cool to room temperature, filter with a membrane with a pore size of 0.45 μm, and adjust the pH of the ink to 9.05 with dilute hydrochloric acid.

[0025] Tests and Results:

[0026] The physical properties of the above-mentioned ink at 24°C are as follows: surface tension 29Mn / m (measured by BZY-2 automatic surface tension meter), viscosity 3.30cP (measured by R / S coaxial cylindrical rheometer), average particle size of ink particles The diameter is 108nm (measured by Malvern particle size tester), the ink has good printing fluency, good printing pattern quality, little or no bleeding, and few burrs.

Embodiment 2

[0028] The red ink for washing label printing in this embodiment includes 0.8% C.I. Acid Red 52, 0.7% C.I. Acid Red 289, 17% diethylene glycol, 8% triethylene glycol monobutyl ether, 0.5 % Surfactant ProxelXL2, balance deionized water.

[0029] Preparation method: mix according to the above formula, then magnetically stir at 50 ° C for 2, cool to room temperature, filter with a membrane with a pore size of 0.45 μm, and adjust the pH of the ink to 9.05 with dilute hydrochloric acid.

[0030] To sum up, the black ink obtained by this method has good pattern quality, is not easy to bleed, has no burrs, has good rubbing fastness, and has certain light fastness, and the preparation method is simple and economical.

Abstract

The invention discloses red printing ink for wash label printing, which comprises the following components according to mass percent: 0.8% of C.I. acid red 52, 0.7% of C.I. acid red 289, 16-19% of diethylene glycol, 6-9% of triethylene glycol monobutyl ether, 0.4-0.5% of surfactant and the balance of deionized water. The invention further discloses a preparation method of the red printing ink for wash label printing. A pattern printed by the red printing ink prepared by the method is good in quality, unlikely to bleed, free of bur and good in fastness to rubbing, and the pattern has certain light fastness.

Description

technical field [0001] The invention belongs to the field of printing, and more particularly, relates to a red ink for washing and printing and a preparation method thereof. Background technique [0002] Ink is an important material for packaging material printing. It expresses patterns and characters on the substrate through printing. The ink includes main components and auxiliary components. They are uniformly mixed and rolled repeatedly to form a viscous colloidal fluid. It consists of pigments, binders, additives and solvents. For books, packaging and decoration, architectural decoration, trademarks and other printing. With the increase of social demand, the variety and output of ink also expand and grow accordingly. [0003] At present, the inks on the market are not environmentally friendly, the printed patterns are of poor quality, easy to bleed, burrs, poor rubbing fastness, and poor light fastness. [0004] In view of this, it is necessary to provide a new type o...
