Problems solved by technology

Although this method can achieve the purpose of fast drying, adding an air-drying device to the top of the pen is not only unsightly but also damages the writing experience, which is not conducive to market application
[0006] Generally speaking, the quick-drying writing instruments announced so far all use volatile solvents or external air-drying functions to speed up the volatilization of the system to achieve quick-drying ink, which has problems such as environmental protection or inconvenient use.

Abstract

The present invention provides a pigment-type quick-drying neutral ink and a ball point pen containing the pigment-type quick-drying neutral ink, wherein the pigment-type quick-drying neutral ink comprises, by weight, 25.0-35.0 parts of an aqueous pigment paste, 10.0-25.0 parts of a humectant, 1.0-5.0 parts of a lubricant, 0.1-0.3 part of a sterilization agent, 1.0-2.0 parts of a pH value adjusting agent, 0.8-1.5 parts of a thickener A, 0.8-1.5 parts of a thickener B, 0.1-0.5 part of a penetrant, and 29.2-61.2 parts of deionized water. According to the present invention, the pigment-type quick-drying neutral ink controls the surface tension and the rheological parameter so as to make the writing line rapidly penetrate on the paper surface, such that the rapid drying purpose is achieved.

Description

technical field [0001] The invention relates to the field of writing implements, in particular to a pigment type quick-drying neutral ink and a ballpoint pen containing the neutral ink. Background technique [0002] As a writing tool, the ballpoint pen is used to meet the functions of recording and marking. With the gradual improvement of people's quality of life, consumers' demand for personalized and functional products is becoming more and more prominent. There are many functional writing products on the market, such as super-smooth medium oil pens, erasable magic friction pens, and large-capacity pens with long writing life. [0003] When writing with a ballpoint pen, due to the slow drying of the stitches, it is accidentally contaminated by hands or other objects and the handwriting is blurred and the paper surface is dirty, which is extremely unfavorable for students' homework or exams. In response to this problem, a kind of quick-drying pen has appeared on the market...
