Abstract
The present invention relates to black resin-free neutral ink of which the raw materials have the components by the following weight proportion: 6 to 14 portions of black pigment, 0.5 to 1 portion of dispersant, 0.15 to 0.5 portion of humectant, 1 to 6 portions of polyvinylpyrrolidone, 0.5 to 2 portions of oleic acid, 20 to 35 portions of water soluble low carbon alcohol, 0.05 to 0.5 portion of benzotriazole, 1 to 3 portions of triethanolamine, 0.1 to 0.5 portion of antiseptic, 0.5 to 2 portions of thickening agents and 55 to 68 portions of deionized water. The present invention has the advantages of homogeneous pigment dispersion, stable system and appropriate viscous flow without changing with time, the writing of neutral ink pens made from the black neutral ink is gliding, and the preservation period is long.
Description
Technical field
The invention belongs to a kind of Neutral writing ink, relate in particular to a kind of black Neutral writing ink that is suitable for ballpoint pen and preparation method thereof.
Technical background
Neutral writing ink pen (gel ink pen) is the novel kind in the ballpoint pen series products, compare with traditional oiliness ballpoint pen, though the appearance time is also not long, because of a Neutral writing ink fluent writing, it is spry and light comfortable to write feel, writing is clear, the color and luster sense is good, and handwriting is water-fast, sun-proof, characteristics such as long preservative period, so accepted by the human consumer rapidly, and obtain widely-used.China produces first big country for the Neutral writing ink pen, but produces the almost whole dependence on import of the used ink of Neutral writing ink pen so far, mainly comes from Japan, Korea S, the U.S. and Germany.
The suspension of Neutral writing ink series pigments particulate, because solid pigment density is obviously greater than fluid density, so in fact Neutral writing ink belongs to Unstable Systems, the present external product quality guaranteed period only is about 1 year.In order to improve the stability of Neutral writing ink, all be added with the aqueous polymer resin in the existing prescription, as polyacrylic acid water-base resin (United States Patent (USP) technology, application number 09/947,191, US2002/0071709A1, be added with the acrylic resin of the molecular weight ranges 5000-10000 of 2wt.% in the prescription), increased the shelf-time of ink to a certain extent, but since the fluoropolymer resin introduced itself or be easy to generate polymerization and crosslinked with organic solvent that system exists, the molecular resin amount is constantly increase with the increase of preservation period, cause ink viscosity to improve, mobile variation, thus cause gel ink pen postpone of a specified duration to go out Mo Buchang, even can't normally write.
