Description

technical field [0001] The invention belongs to the application field of fine chemicals, and in particular relates to a pigment carbon black gel pen ink and a preparation method thereof. technical background [0002] The gel pen is a new type of writing tool that is currently popular in the world. The so-called "neutral" of a gel pen means that its ink viscosity is between the viscosity of oil-based ball-point pen ink and the viscosity of water-based ball-point pen ink. Gel pens use simple pens, medium-viscosity ink and water- and light-resistant pigments as the color base, so that the writing is smooth and smooth, the ink is firm and firm, and can be stored permanently. At the same time, it also has the characteristics of uniform ink flow and long uncapping time. . [0003] Because it overcomes the shortcomings of oily ball-point pens that are not smooth and water-based ball-point pens that are not lubricated. Once the gel pen came out, it has developed rapidly. The ink...
