Quick-drying pen core of rolling pen

Abstract

The invention discloses a quick-drying pen core of a rolling pen. The quick-drying pen core is prepared from the following components in parts by weight: 100 parts of phthalocyanine-series dyes, 25-30 parts of trihydroxymethyl ethane, 12-20 parts of polyurethane-35, 5-15 parts of EVA, 8-14 parts of ethylene glycol, 2-6 parts of dichloromethane, 2-6 parts of sodium hexametaphosphate, 0.5-3 parts of paraffin and 1-4 parts of magnesium stearate VE. The quick-drying pen core of the rolling pen provided by the invention can be completely dried within half a second after writing, so that the paper surface is not stained due to the touch of hands, and the lines are clear.

Description

technical field [0001] The invention relates to a ball pen refill material. Background technique [0002] Ballpoint pen, also called ballpoint pen or ballpoint pen, is a writing tool that uses dry thick ink, which is brought out by the freely rotating steel ball on the pen tip and transferred to paper. It is longer, does not need to be filled with ink frequently, and the price is relatively low. It is the most popular writing tool in the world in recent years. [0003] The writing principle of the rollerball pen is mainly to use the direct contact between the ball and the paper surface to generate friction when writing, so that the ball rolls in the ball seat and brings out the ink or ink in the refill to achieve the purpose of writing. [0004] A rollerball pen is a pen that uses ink and different pigments to write. The tip of the pen is a small steel ball. The small steel ball is embedded in a small cylindrical copper bowl, and then connected to a plastic tube with ink. ...

AI Technical Summary

Problems solved by technology

Because the salt-based dyes are not lightfast (the lightfastness is only 1-2), not heat-resistant, not resistant to acid and alkali, so the durability is poor, and has been eliminated

[0006] At present, the refills of rollerball pens still cannot be used in formal occasions. There are two main reasons for this. One is that it dries slowly, and it is easy to stain the paper and make the writing blurred. The other is that the ink has poor stability and should not be used for a long time. save
