Pigment type neutral pen ink having good freezing resistance

Abstract

Pigment type neutral pen ink having good freezing resistance is prepared from, by mass, 0.5-2 parts of sorbitol powder, 1-1.5 parts of a thickening agent, 0.5-1 part of an antirust agent, 0.5-1 part of fungicide, 0.2-0.5 part of a wetting agent, 0.1-0.2 part of a flatting agent, 0.5-1.5 parts of an antifreeze agent, 15-25 parts of pigment type color paste and 60-75 parts of purified water through mixing. The ink enables writing on paper to be smooth, can adapt to writing on various types of paper, lines of writings on the various types of paper are attractive, normal writing can be performed in winter or in other lower-temperature environments, and no line breakage occurs.

Description

Technical field: [0001] The invention relates to the technical field of inks, in particular to a pigment type gel pen ink with excellent frost resistance. Background technique: [0002] Now more and more students use gel pens and ballpoint pens to write. They don't need to absorb ink frequently, but they can write the effect of pen characters, so they are very popular among students. However, many neutral inks on the market are not frost-resistant enough. When the weather is cold, especially in the northern market, the writing effect is not good, and there will be situations of no writing and short lines, which seriously affect normal writing. Invention content: [0003] In order to solve the existing problems of the background technology, the present invention adopts the following technical scheme: it is formed by mixing the following components and mass ratios: 0.5-2 parts of sorbitol powder, 1-1.5 parts of thickener, 0.5-1 part of antirust agent 0.5-1 part of fungicide...
