Embodiment 1

[0033] Example 1: The preparation process of blue neutral ink is as follows:

[0034] 1. Preparation of phthalocyanine blue paste: Weigh a certain amount of hyperdispersant, mix it fully with deionized water, add phthalocyanine blue pigment into the above solution until the pigment particles are all wetted, and obtain a predispersion of the pigment. Use a basket grinder to grind for 1.5 hours, place the coarse color paste formed after the basket grinder in a nano-grinder until the pigment particle size D90<350nm is discharged, and obtain a phthalocyanine blue paste system;

[0035] 2. Preparation of mixing and dispersing aids: After uniformly mixing lubricant, humectant, defoamer, fungicide, and pH regulator, etc., stir evenly to obtain a mixed solution, and heat at 50°C;

[0036] 3. Preparation of blue neutral ink: Add phthalocyanine blue paste to the above mixed solution, bathe in water at 50°C for 1 hour, then stir at 4000rpm at high speed for 10 minutes, and finally add ...

Embodiment 2

[0048] Example 2: The preparation process of the blue neutral ink of the present embodiment is identical with embodiment 1, and ink formula is as follows:

[0049] Phthalocyanine blue pigment, 10%

[0050] Hyperdispersant Y3, 5%

[0051] Lubricant (oleic acid), 1%

[0052] Humectant (Diethylene Glycol), 25%

[0053] Thickener (PTF), 3%

[0054] Defoamer (n-octanol), 0.5%

[0055] Fungicide (imidazoline), 1%

[0056] PH regulator (triethanolamine), 2%

[0057] Deionized water 52.5%

[0058] The blue neutral ink is bright in color, bright in color, comfortable to the touch when writing, round and smooth, full in lines, and even in ink. The performance test results of the ink are shown in Table 1.

Embodiment 3

[0060] The preparation process of the blue neutral ink of the present embodiment is identical with embodiment 1, and ink formula is as follows:

[0061] Phthalocyanine blue pigment, 10%

[0062] Hyperdispersant Y3, 6%

[0063] Lubricant (oleic acid, fluorosilicone oil compounded at a mass ratio of 1:1), 1%

[0064] Moisturizing agent (polyethylene glycol 200, glycerol compounded at a mass ratio of 1:1), 20%

[0065] Thickener (PTF), 1%

[0066] Defoamer (n-octanol), 0.5%

[0067] Fungicide (imidazoline), 1%

[0068] PH regulator (triethanolamine), 1%

[0069] Deionized water 59.5%

[0070] The blue neutral ink is bright in color, bright in color, comfortable to the touch when writing, round and smooth, full in lines, and even in ink. The performance test results of the ink are shown in Table 1.

Abstract

The invention relates to a blue neutral ink and a preparation method thereof. The blue neutral ink comprises the following components in percentage by mass: 8-12 parts of a phthalocyanine blue pigment, 4-6% of a hyperdispersant, 1-3% of a lubricant, 10-30% of a humectant, 1-3% of a thickener, 0.5% of a defoaming agent, 1% of a bactericidal agent, 3-5% of a PH modifier and 39.5-72.5% of deionized water. The blue neutral ink is of a bright color, can be used for writing words of bright color, has the advantages of comfortable handfeel, rich and fluent writing effect, full lines and uniform ink release when used for writing, and has good stability after long-term storage.

Description

technical field [0001] The invention relates to a blue neutral ink and a preparation method thereof. Background technique [0002] Blue gel ink is one of the most commonly used inks, and a large amount of blue gel ink is demanded all over the world every year. The output of my country's gel pens has reached more than 1 billion, of which the export volume exceeds 700 million, but the nib and ink are all imported, so the price has been high, and the high price of imported neutral ink has become a burden for my country's pen manufacturers. As a result, my country's pen-making companies have become "profit porters" for foreign ink companies, making the sustainable development of the industry lose the initiative. The reason is that the poor stability and easy aggregation of blue ink are the biggest technical bottlenecks restricting the quality of domestic blue ink. [0003] At present, there have been related reports on the patent of the neutral ink preparation method, such as p...
