Problems solved by technology

The fly in the ointment is that because the water-based ballpoint pen uses pure water-based ink, the paper has a strong absorption of ink, resulting in frequent feathering of the handwriting. There is a great risk in the writing of documents in formal occasions, the signing of agreements, etc., and it is beautiful It is also uncoordinated, which limits the application range of water-based ballpoint pens
Although the water-based inks prepared by the prior art can reduce feathering, these inks are only used in inkjet technology and cannot be applied to water-based ballpoint pens

Embodiment 1

[0029] Add 8.0 parts by weight of propylene glycol, 0.4 parts by weight of hydroxysulfonate, 0.3 parts by weight of polyoxyethylene polyoxypropylene monobutyl ether, 25.0 parts by weight of acrylic resin, and 1.0 parts by weight of triethanolamine to 65.0 parts by weight of deionized After uniform dispersion in water, add 25.0 parts by weight of high-pigment carbon black while stirring to fully wet the carbon black, and evenly disperse it in the above-mentioned mixed solution to make a color paste. Then emulsify the prepared color paste with an emulsifier for 10 minutes to obtain a color paste precursor; transfer the color paste precursor to a horizontal sand mill filled with 0.3mm diameter zirconium beads, and start circular grinding, During the grinding process, the temperature of the material is controlled at 25° C. until the particle size of the material is less than or equal to 88 nm, and the grinding is completed. After the material is discharged, the acrylic resin pigmen...

[0032] Add 7.0 parts by weight of propylene glycol, 0.3 parts by weight of hydroxysulfonate, 0.4 parts by weight of polyoxyethylene polyoxypropylene monobutyl ether, 20.0 parts by weight of acrylic resin, and 2.0 parts by weight of triethanolamine to 70.0 parts by weight of deionized After uniform dispersion in water, add 30.0 parts by weight of high-pigment carbon black while stirring to fully wet the carbon black, and evenly disperse it in the above-mentioned mixed solution to make a color paste. Then emulsify the prepared color paste with an emulsifier for 10 minutes to obtain a color paste precursor; transfer the color paste precursor to a horizontal sand mill filled with 0.4mm diameter zirconium beads, and start circular grinding, During the grinding process, the temperature of the material is controlled at 30°C until the particle size of the material is less than or equal to 90nm, and the grinding is completed, and the acrylic resin pigment paste is obtained after the mat...

Embodiment 3

[0035] (1) In parts by weight, 20.0 parts of deionized water was heated at a constant temperature of 65°C, and then 0.01 part of an acrylamide water-soluble polymer with a molecular weight of 3 million and a solid content of 88.5% was added under constant stirring. In deionized water, keep stirring until it is completely dissolved, and place it to cool to obtain a viscous aqueous solution of acrylamide water-soluble polymer;

[0036] (2) Add 10.0 parts of propylene glycol, 0.1 part of benzotriazole, 0.1 part of fatty acid polyoxyethylene ether, and 1.0 part of diethylene glycol into 10.0 parts of deionized water to obtain a mixture, and stir for 1.0 h to obtain an ink base liquid;

[0037] (3) Then, the acrylamide water-soluble polymer aqueous solution obtained by completely dissolving the step (1) is added into the ink base liquid of the step (2) under stirring state, and mixed and stirred for 1.0 h;

[0038] (4) Finally, add 22.0 parts of acrylic resin pigment paste with a p...

Abstract

The invention belongs to the technical field of ink, and discloses pigment type roller pen ink capable of avoiding blurring of handwriting and a preparation method thereof. The pigment type roller pen ink comprises the following components in parts by mass: 10.0-15.0 parts of a humectant, 0.01-0.03 parts of an acrylamide water-soluble polymer, 0.1-0.3 parts of a preservative, 0.1-0.3 parts of a lubricant, 1.0-5.0 parts of an auxiliary agent, 22.0-28.0 parts of pigment type color paste and 51.37-61.79 parts of deionized water. The prepared ink is low in viscosity, so that ink feeding is smooth, writing is fluent, writing is not blurred during application, no obvious trace exists on the back face of writing paper, and the trace is kept visible after being wiped. The ink can be applied to important occasions such as writing of files and signing of agreements in official occasions.

Description

technical field [0001] The invention relates to the technical field of ink, and more specifically relates to a pigment-type ballpoint pen ink with no feathering of handwriting and a preparation method thereof. Background technique [0002] Since 1984, Japan's SARURA Co., Ltd. has developed a product called "Ballsign" and put it on the market. In 1988, another Japanese company, Pentel Co., Ltd., developed a product called "Hybrid". Thus was born. With the development of gel pens, they are classified into three categories according to their different writing media: the writing instruments whose writing media are oily and use the ball ball to roll out the writing media (ink or ink) are collectively called ballpoint pens; Those whose writing medium is water-based are called water-based ballpoint pens (water-based ink pens), also known as rollerball pens and ballpoint pens; and those whose writing medium has a viscosity between water-based and oily are called gel pens. With the...
