Embodiment 1

[0028] A highly weather-resistant inkjet ink composition, based on weight percentage, prepared from the following components: rutile titanium dioxide: 20%, SN-5040 dispersant: 10%, LR-9610: 30%, propylene three Alcohol: 5%, propylene glycol: 2%, Capstone FS-61: 1.5%, sodium hydroxide: 0.01%, citric acid: 0.1%, triethanolamine: 0.1%, 5-chloro-2-methyl-4-isothiazole Lin-3-one: 0.05%, deionized water: the balance. The preparation steps of the inkjet ink composition include:

[0029] 1) The weight of rutile titanium dioxide, SN-5040 dispersant, glycerol, Capstone FS-61, triethanolamine, 5-chloro-2-methyl-4-isothiazolin-3-one, and the After mixing the ionized water, grind it with a nano sand mill until the particle size of the mixture is D90≤200nm;

[0030] 2) Add LR-9610 of the above weight to the ground mixture of step 1), stir and mix well at a speed of 300 rad / min, and filter with a filter with a filtration accuracy of 0.22 μm to obtain the spray Ink ink composition.

Embodiment 2

[0032] A highly weatherable inkjet ink composition, calculated by weight percentage, which is prepared from the following components: C.I. Pigment Black 7:1%, DF1213 dispersant: 0.2%, HD-8327: 15%, glycerol: 15%, propylene glycol methyl ether: 15%, PF151N: 0.01%, lactic acid: 0.5%, triethanolamine: 1%, 5-chloro-2-methyl-4-isothiazolin-3-one: 0.05%, deionized water: the balance. The preparation process of the inkjet ink composition is similar to that of Example 1.

Embodiment 3

[0034] A highly weatherable inkjet ink composition, based on weight percentage, prepared from the following components: Pigment Blue 28: 5%, SN-5040 dispersant: 3%, HD-8327: 20%, ethanol: 10%, 1,2-hexanediol: 10%, Capstone FS-61: 1%, citric acid: 1%, lactic acid: 0.2%, 5-chloro-2-methyl-4-isothiazoline-3- Ketone: 0.05%, deionized water: the balance. The preparation process of the inkjet ink composition is similar to that of Example 1.

Abstract

The invention discloses a high-wear resistance inkjet ink composition. The inkjet ink composition is prepared from 1-20 wt% of a pigment, 0.2-10 wt% of a dispersant, 5-30 wt% of a polymer, 5-30 wt% of a humectant, 0.01-1.5 wt% of a surfactant, 0.1-1.5 wt% of a pH adjuster, 0.05-0.5 wt% of a fungicide, and the balance of deionized water. A preparation method of the inkjet ink composition comprises the following steps: 1) mixing and grinding the pigment, the dispersant, the humectant, the surfactant, the pH adjuster, the bactericide and the deionized water according to above weight percentages until the particle size D90 of the obtained mixture is not more than 200 nm; and 2) adding the polymer to the ground mixture obtained in step 1), stirring and uniformly mixing the mixture and the polymer, and filtering the newly obtained mixture to obtain the inkjet ink composition. The inkjet ink composition has the advantages of simple preparation method, high weather resistance, excellent storage stability and excellent printing stability.

Description

Technical field [0001] The invention relates to an ink composition, in particular to an aqueous inkjet ink composition with high weather resistance. In addition, the present invention also relates to a method for preparing the inkjet ink composition. It belongs to the technical field of inkjet printing. Background technique [0002] Fluorocarbon coating refers to coatings with fluororesin as the main film-forming substance. In recent years, fluorocarbon coatings have become a kind of coatings with excellent comprehensive performance and develop rapidly with their own unique functions such as super weather resistance, heavy anti-corrosion, anti-staining, flame retardant and antibacterial. Fluorocarbon coatings are mainly divided into powder fluorocarbon coatings, solvent-based fluorocarbon coatings and water-based fluorocarbon coatings. Among them, due to the environmental protection of water-based fluorocarbon coatings, more and more people pay attention. [0003] Due to the hig...
