Neutral ink base material with wide application and flash neutral ink prepared by same

Abstract

The invention discloses medium-viscosity water-borne paint ink base material with wide application and flash medium-viscosity water-borne paint ink prepared by the same. The ink base material comprises the following components in parts by weight: 40 to 60 parts of deionized water, 15 to 45 parts of alcohol, 1 to 10 parts of wetting agent, 0.3 to 10 parts of active agent, 0.5 to 3 parts of coupling agent, 1 to 5 parts of thickener, 0.01 to 1 part of antifreeze agent, 0.01 to 0.3 part of preservative, and 0.05 to 0.5 part of defoamer. The base material has the characteristic of wide application, not only can be used for preparing conventional neutral ink, but also is suitable for preparation of flash neutral ink. The flash neutral ink consists of the following components in parts by weight:60 to 90 parts of the binder, 0.1 to 5 parts of flash color paste, 1 to 10 parts of performance additive, and 5 to 25 parts of deionized water. The neutral ink has proper viscosity and stable system,and overcomes the defects of pen block, ink leakage, over ink and the like in writing.

Description

technical field [0001] The present invention relates to writing materials, in particular, the present invention is a neutral ink base material with wide applicability and the flash neutral ink prepared therefrom. Background technique [0002] At present, China is a big pen-making country. For example, the annual output of fountain pens has reached about 200 million pieces, ranking first in the world; the output of ballpoint pens exceeds 15 billion pieces, ranking first in the world; the annual output of mechanical pencils is about 500 million pieces, ranking third in the world. . But China is not a strong pen-making country, and some core technologies of the pen-making industry have not yet been mastered. Especially for gel pens that have the advantages of smooth writing, clear handwriting, good color feeling, and light resistance, etc., which are rapidly rising in the market, there is insufficient preparation and insufficient research. Neutral ink as a key material still ...

AI Technical Summary

Problems solved by technology

For example: poor versatility of base materials, residual harmful substances, insufficient improvement of ink system stability, single compatibility with other pen-making materials, etc.

[0004] Chinese patent application CN101319112 discloses a kind of water-based pigment neutral ink, which adopts polycarboxylate to improve the defects of easy delamination, precipitation and poor storage stability of pigment ink

[0005] Chinese patent application CN101302379 then provides a kind of dye type neutral ink, and its color and luster is limited to five kinds, and its base material is a kind of high molecular copolymer that is made through condensation of sulfosalicylic acid, formaldehyde and acetic acid, because The reactant contains concentrated sulfuric acid, formaldehyde, sulfosalicylic acid, acetic acid, etc., which may have an impact on the environment during the synthesis process, especially when there is formaldehyde residue, it will cause certain harm to the pen user. harm

[0006] Chinese patent application CN101104760 has introduced a kind of preparation method of carbon black neutral ink, and this method and CN1847329, CN1847330 and CN1847331 are respectively the same as no resin red, blue color, green neutral ink and preparation method thereof, their base material exists Single disadvantage of applicability to color (dye) materials
