Example Embodiment

[0022] An aqueous ink composition for inkjet printers, consisting of the following weight (kg) raw materials:

[0023] Water-soluble rosin modified maleic resin 25

[0024] Pigment 12

[0025] 2-amino-2-methyl-1-propanol 7

[0026] Tall oil 5

[0027] Waterborne high density polyethylene wax 1

[0028] Ethylene glycol butyl ether 8

[0029] Cocamidopropyl amine oxide 1.5

[0030] Sodium nonylphenol polyoxyethylene ether sulfate 1

[0031] Isopropyl tris (dioctyl pyrophosphate acyloxy) titanate 0.8

[0032] Simethicone 0.7

[0033] Composite filler 4

[0034] Deionized water 22.

[0035] The preparation method of the composite filler is as follows: a. Weigh the bentonite, barite and illite in a weight ratio of 5:3:2 and mix them evenly, calcinate at 6560°C for 3h, cool to room temperature and add a 20% hydrochloric acid solution Soak in medium for 25min, take it out and wash it with deionized water to neutrality, dry it, calcinate at 830℃ for 1h, crush, add 4% sodium lignosulfonate, 2% trie...

Abstract

The invention discloses a water-based ink composition for an ink-jet printer. The composition comprises the following raw materials in parts by weight: 20-30 parts of water-soluble rosin modified maleic resin, 10-15 parts of pigment, 5-10 parts of 2-amino-2-methyl-1-propanol, 4-6 parts of tall oil, 1-2 parts of water-based high-density polyethylene wax, 5-10 parts of butyl cellosolve, 1-2 parts of cocamidopropyl dimethylamine oxide, 1-2 parts of sodium nonylphenol polyoxyethylene ether sulfate, 0.5-1 part of isopropyl tri(dioctylpyrophosphate) titanate, 0.5-1 part of dimethyl silicone oil, 3-5 parts of composite filler, and 15-25 parts of deionized water. The water-based ink can be dispersed uniformly, is excellent in comprehensive performance, good in saving stability, good in printing adaptability of typed characters, high in glossiness and high in adhesion, has excellent water-proofing, wipe-proofing, solvent-proofing, mildew-proofing and antibacterial performances, is environment-friendly, can completely meet the requirement of ink-jet printing to the performance of water-base ink, and has important economic and social values.

Description

technical field [0001] The invention relates to an ink composition, in particular to a water-based ink composition for an inkjet printer. Background technique [0002] The mass fraction of volatile organic compounds (VOC) in traditional solvent-based inks is as high as 50%-80%, which not only consumes a large amount of organic solvents, but also causes environmental pollution and seriously endangers human health. Because water-based ink does not contain volatile organic solvents, it greatly reduces the emission of volatile organic compounds (VOC), thereby reducing air pollution and improving the safety environment of printing operators. It is more and more widely used and has replaced solvent-based inks. part of the market share. However, the current domestic water-based inks have problems such as poor stability, poor water resistance, low gloss and low adhesion fastness, which seriously hinder the development and application of water-based inks in inkjet printing. Conten...
