Problems solved by technology

In order to improve the stability of neutral ink, polymer water-based resin is all added in the existing formula, such as polyacrylic acid water-based resin (U.S. patent technology, application number 09 / 947,191, US2002 / OO717O9A1, add the molecular weight range of 2wt% in the formula 5000-10000 acrylic resin), which increases the storage time of the ink to a certain extent, but because the introduced polymer resin itself or the organic solvent present in the system are prone to polymerization and crosslinking, the molecular weight of the resin increases with the storage period. And the continuous increase will lead to the increase of ink viscosity and poor fluidity, which will lead to poor ink output after long-term storage of gel pens, and even failure to write normally.

Abstract

The present invention is one kind of resin-free neutral blue ink, and features the resin-free neutral blue ink comprising phthalocyanine blue pigment 8-14 weight portions, dispersant 0.5-1 weight portion, wetting agent 0.15-0.5 weight portion, PVP 1-6 weight portions, oleic acid 0.5-2 weight portions, water soluble lower alcohol 20-35 weight portions, benzotriazole 0.05-0.5 weight portion, triethanolamine 1-3 weight portions, preservative 0.1-0.5 weight portion, thickener 0.5-2 weight portions, and deionized water 55-65 weight portions. The present invention has the advantages of homogeneous pigment dispersion, stable system, proper and stable flowability, influent writing and long preservation period.

Description

technical field [0001] The invention belongs to a neutral ink, in particular to a blue neutral ink suitable for a ballpoint pen and a preparation method thereof. technical background [0002] Neutral ink pen (gel pen) is a new type of ballpoint pen products. Compared with traditional oily ballpoint pens, it has not been around for a long time, but because of the smooth writing of neutral ink pens, the writing feels light and comfortable, and the writing is clear. It has good color sense, and the handwriting is water-resistant, light-resistant, and has a long shelf life, so it is quickly accepted by consumers and widely used. my country is the largest country in the production of gel ink pens, but so far the ink used in the production of gel ink pens is almost entirely dependent on imports, mainly from Japan, South Korea, the United States and Germany. [0003] Neutral ink is a suspension of pigment particles. Because the density of solid pigment is significantly greater tha...
