CN104046129A - No-drying yellow ink for water gel pen - Google Patents

Abstract

The invention discloses no-drying yellow ink for a water gel pen. The ink is prepared from the following components in percentage by weight: 1-18% of a colorant, 0.5-5% of a thickener, 0.01-0.5% of a lubricant, 0.5-5% of a pH adjustor, 0.1-5% of a fungicide and 80-95% of water. By using a polyether chain-containing aniline azo yellow dye which is liquid at room temperature, sticky and flowing, bright in color and safe and non-toxic as the colorant which is matched with a water-based ink formula system, the ink can be used for preparing ink with long uncapping time and unblocked pen point and is particularly suitable for a water-based ball point pen.

Description

A non-drying water-based pen yellow ink

technical field

The invention relates to a water-based pen yellow ink, in particular to a non-drying water-based pen yellow ink.

Background technique

For water-based ballpoint pen ink, it is generally required to have good writing performance-clear writing, good lubricity, and good uniformity of lines, etc. It is also required to have excellent cap removal, that is, to place it in the state of removing the pen cap for a long time, with a pen tip The non-drying property can achieve the effect of instant writing. If you want to improve the non-drying performance of the water-based ballpoint pen, you need to add a large amount of humectant, so that the performance of the ink will not meet the target; to ensure the writing performance of the ink, the water-based ballpoint pen has poor moisture retention, and the cap will be blocked for a long time. Cannot write on the fly.

CN1415674A discloses the yellow ink composition of water-based ballpoint pen, selects the black colorant that solubility is large, compatibility is good acidic or direct dyestuff-red, yellow, blue three primary colors are blended together, adds purified water, non-aqueous polar solvent, corrosion inhibitor Additives, preservatives, solubilizers, viscosity reducers, acidity regulators, etc. are used to make black ink. This ink is used in ballpoint pens. It can be stored for up to 14 days without the cap, and it cannot achieve the characteristics of non-drying. Therefore, in order to solve the disadvantages of poor cap-opening properties of inks formulated with traditional dyes due to inorganic salts and poor solubility, it is necessary to modify the structure of the dyes so that the dyes can match the ink formulation system.

Contents of the invention

Aiming at the deficiencies of the prior art, the invention provides a non-drying water-based pen yellow ink which has good reconstitution of dye and ink and does not block the pen head.

In order to achieve the above object, the technical scheme adopted by the present invention is as follows:

A kind of non-drying water-based pen yellow ink is formulated by the following components by weight percentage:

Coloring agent 1-18%;

Thickener 0.5-5%;

Lubricant 0.01～0.5%;

pH regulator 0.5-5%;

Antiseptic and fungicide 0.1-5%;

80-95% water.

The above-mentioned colorant is selected from azo yellow dye containing polyether chain aniline.

The above-mentioned thickener is polyvinylpyrrolidone and/or polyvinyl alcohol.

The aforementioned lubricants are phosphate esters.

The above-mentioned pH regulator is triethanolamine.

Above-mentioned anticorrosion bactericide is isothiazolinone

The above water is deionized water.

Further, a kind of non-drying water-based pen yellow ink is formulated from the following components by weight percentage:

Coloring agent 7-8%;

Thickener 1.5-2%;

Lubricant 0.1～0.2%;

pH regulator 0.02-0.05%;

Antiseptic bactericide 0.5%;

The rest is water.

The compounding method of the present invention is: according to the component of the raw material of non-drying water-based pen yellow ink and percentage by weight, under room temperature condition, polyether chain aniline azo yellow dye is dissolved in deionized water; Add thickeners, lubricants, preservatives and fungicides gradually; finally add pH regulator, mix well and stir evenly.

Compared with the prior art, the beneficial effects of the present invention are as follows:

The present invention selects polyether dyes that are liquid at room temperature, viscous and flowing, brightly colored, safe and non-toxic as the coloring agent, which matches the water-based ink formula system, and can be used to prepare inks that have a long uncapping time and do not block the tip of the pen; in addition , the invention has simple formula, easy process control, good safety, good stability and good writing performance, and is especially suitable for water-based ballpoint pens.
