Description
Technical field
The present invention relates to a kind of ink and manufacture method thereof, relate to a kind of ethereal blue Neutral writing ink and manufacture method thereof particularly.
Background technology
Characteristics such as gel ink pen has fluent writing, hand feel and drape, writing is water-fast, sun-proof, shelf time are long, thereby become at present popular writing implement in the world.With regard to China, middle nineteen nineties, a domestic part factory begins to set foot in the production of gel ink pen, and through the effort in surplus ten years, the gel ink pen volume of production and marketing of China now occupied prostatitis, the world.But the higher Neutral writing ink of its technology content is dependence on import still, mainly from Japan, Germany, the U.S. and Korea S, so price remains high always.For making China develop into system pen power by a system big country, domestic many factories and research unit carry out a large amount of exploratory studys to the Neutral writing ink technology of preparing.Usually the Neutral writing ink of office usefulness comprises black Neutral writing ink, blue-black Neutral writing ink, ethereal blue Neutral writing ink (described " ethereal blue " is relative " blue-black ", and therefore described " ethereal blue Neutral writing ink " also can be called " blue Neutral writing ink ").But present ethereal blue Neutral writing ink is generally pigment style, does not still resolve the efficient dispersion and the emulsification of pigment fully, causes product stability poor, and long-term storage is prone to precipitation and blocks nib, and color and luster dimness, corrodibility are strong simultaneously, the phenomenon of swimming occurs.And the dye-type Neutral writing ink has that manufacturing process is simple, steady quality, rich color are bright-coloured, write along advantage such as sliding, but that its maximum shortcoming is a handwriting is not water-fast.
In sum, this area lacks a kind of good stability, the water-proof ethereal blue Neutral writing ink of writing.Therefore, this area presses for exploitation good stability, the water-proof ethereal blue Neutral writing ink of writing.
Summary of the invention
First purpose of the present invention is to obtain a kind of good stability, the water-proof ethereal blue Neutral writing ink of writing.
Second purpose of the present invention is to obtain the preparation method of a kind of good stability, the water-proof ethereal blue Neutral writing ink of writing.
Provide a kind of ethereal blue Neutral writing ink in a first aspect of the present invention, it comprises following component:
(a) water-soluble blue dyes 2.0-7.0 weight part
(b) thickening material 0.1-0.2 weight part

(e) Antisepticize and mildew preventive 0.05-0.3 weight part
(f) auxiliary agent 0.1-0.5 weight part
(g) water 74.5-82.25 weight part;
And the weight summation of above-mentioned (a)～(g) component accounts for 95～100% of composition total weight.
A second aspect of the present invention provides a kind of preparation method of ethereal blue Neutral writing ink, comprises the steps:
(1) provides the water-soluble blue dyes 2.0-7.0 of following component (a) weight part, (b) thickening material 0.1-0.2 weight part, (c) acrylic resin 0.5-2.5 weight part, (d) wetting Agent for Printing Inks 10.0-15.0 weight part, (e) Antisepticize and mildew preventive 0.05-0.3 weight part, (f) auxiliary agent 0.1-0.5 weight part, (g) water 74.5-82.25 weight part; And the weight summation of above-mentioned (a)～(g) component accounts for 95～100% of composition total weight;
(2) successively the described wetting Agent for Printing Inks of step (1), Antisepticize and mildew preventive, auxiliary agent, acrylic resin, water-soluble blue dyes are added in the entry; Obtain mixture;
(3) after the mixture stirring fully with step (2), add described thickening material, and restir fully obtains described ethereal blue Neutral writing ink.
Embodiment
The inventor by improving preparation technology, has obtained the inventor through extensive and deep research through extensive and deep research, by a large amount of raw material screenings and prescription trial-production, has obtained a kind of water-fast effective ethereal blue dyestuff Neutral writing ink.And finished the present invention on this basis.Finished the present invention on this basis.
Herein, described " Neutral writing ink " except as otherwise noted, refers to viscosity and is positioned at ink between water-base ink (for example fountain pen ink) and oil-based ink (for example ball pen ink) viscosity.The implication of described " Neutral writing ink " is known for those skilled in the art.Particularly, Neutral writing ink of the present invention is a water soluble dyestuffs type Neutral writing ink, and " water-based " is meant that the main body solvent of ink is a water, and " dye-type " is meant that coloring material is a dye granule.
Herein, described " water-fast effective ", except as otherwise noted, it is still clear and legible after 1 hour to refer to the handwriting water logging.
Herein, described " ethereal blue ", typically referring to Pantone look card number is the color gamut of 2726C～2736C.
Unless otherwise defined or explanation, same meanings of being familiar with of all specialties used herein and scientific words and those skilled in the art.Any in addition method similar or impartial to described content and material all can be applicable in the inventive method.In addition, raw material of the present invention all can obtain or conventional synthetic method prepares by commercially available.
Below each component of the present invention is elaborated.
Dyestuff
The present invention can adopt various water-soluble dyes.
Preferably, in order to reach the better fit purpose, select acidity or substantive dyestuff for use.For example, can select Acid Blue 7, acid blue 9, Blue VRS, sun blue 199, sun blue 106, sun blue 86, sun blue 84, sun blue 74, sun blue 70 etc. (the described CI of being numbered Colour Index numbering) for use.
The consumption of dyestuff is too high, can cause the dyestuff cohesion, stops up nib; If consumption is low excessively, ink color insufficient strength then, writing color and luster dimness.Comparatively suitable, the consumption of dyestuff is at the 2.0-7.0 weight part.(this moment, amount of thickener was that 0.1-0.2 weight part, resin content are that 0.5-2.5 weight part, wetting Agent for Printing Inks content are that 10.0-15.0 weight part, fungus-proof antisepsis agent content are that 0.05-0.3 weight part, auxiliary agent content are that 0.1-0.5 weight part, deionized water content are the 74.5-82.25 weight part)
