Abstract
A water black ink composition for ball-point pen is prepared from water-soluble dyes (red, yellow and blue), purified water, polar solvent, corrosion inhibitor, dissolving promoter, viscosity regulator, acidity regulator, etc. Its advantage is excellent drying and high temp resistance.
Description
The present invention relates to a kind of fluid of writing with pen, specifically, relate to a kind of water base India ink of writing with ballpoint pen.
The colorant of the used with water ball-point pens India ink in past is carbon black or single black pigment or dyestuff.Carbon black, pigment is water insoluble and non-aqueous polar solvent, and it is very limited to absorb alternative black dyes in whole visible spectrum tool balance, and molar mass is big and cause water-soluble reduction relatively.The lines color and luster that the ballpoint pen made from this type of India ink is write is more shallow, desiccation resistance (' raising one's hat property ') is relatively poor, and ink is to written tool corrodibility, writes feel and lines homogeneity and is difficult to satisfy and normally writes needs.
The objective of the invention is to provide a kind of drawback that can overcome above-mentioned existing aqueous ballpoint pen India ink, and has good writing quality, color and luster is dark, coloured light can be selected, and has the excellent anti-drying and the aqueous ballpoint pen India ink composition of resistance to elevated temperatures simultaneously.
Technical scheme of the present invention is: be chosen in solubleness is big, compatibleness is good in the mixed solvent of nearly neutral water and ethylene glycol acidity or substantive dyestuff-red, yellow, primary colors are combined into black pigment; Make chaotropic agent with organic bases; Be equipped with the improved properties auxiliary agent; Prepare aqueous ballpoint pen India ink composition by the physics and chemistry allocation processing.
Realize the detailed description of the object of the invention
The used colorant of aqueous ballpoint pen India ink composition of the present invention is different from and only adopts single colorant to make tinting material in the prior art, but adopt water-soluble red, yellow, primary colors dyestuff fabulous, that molar mass is lower, polarity is big relatively, at least use three kinds of dye combinations, the requirement of black coloured light (routine ruddiness is black, blue light black) colorant match allotment is by a certain percentage formed according to the user.This technology has been expanded the selectable range of dyestuff greatly, for preventing that separating out dyestuff because of moisture evaporation in the ink stops up written significant.Operable dyestuff example includes, but is not limited to redness: acid bright red 3r (C.I.16255), Acid Red B (C.I.14720), acid bright red b S (C.I.16045), direct pink (C.I.29100); Yellow: Methanil Yellow G (C.I.13065), Acid Orange II (C.I.15510), acid orange G (C.I.16230), direct orange S (C.I.29150); Blue: acid navy blue R (C.I.13390), acid blue-black 10b (C.I.20470), sun blue 3B (C.I.23850), direct acid blue 5B (C.I.24400); Used have the black dyes that can add remarkable decrement in the colorant: direct fast black G (C.I.35255), an acid particle element (C.I.50420).
In order to improve the flow condition of ink in the excellent capillary channel of feedwater, adding in composition for ink and being used for the suitable chaotropic agent of this purpose is urea, short carbon chain fatty amine and anion surfactant one Sodium dodecylbenzene sulfonate.
Aqueous ballpoint pen India ink composition of the present invention adopts water and non-polar solvent mixture to make solvent.Non-aqueous polar solvent comprises: ethylene glycol, glycerol, low-molecular-weight polyoxyethylene glycol, trolamine, these solvents all can be miscible with water, have good moisture preserving, wetting action.
Ball pen head adopts copper or Cu alloy material mostly at present, and water-base ink is a kind of polar electrolyte solution, and long-term the contact with air of nib that fills ink forms corrosion cell, and be very serious to the corrosion of written material.Corrosion results is that ball comes off or corrosion product stops up nib, and ballpoint pen can not normally be write.By adding the nitrogen heterocyclic ring class organic compound corrosion speed of ink that can slow down greatly to written material.Be applicable to that limiting examples of the present invention is that toluene triazole, benzo are narrowed azoles, benzoglyoxaline triazole, benzotriazole.
The non-limiting acidity regulator example that is suitable for use among the present invention is that sodium hydroxide, examples of preservatives are that Sodium Benzoate, viscosity modifier example are xanthan gum.
The composition and the weight percent of the aqueous ballpoint pen India ink composition material that requires according to right 1, each component is handled through physics and chemistry such as batching, mixing, stirring, filtrations and is made aqueous ballpoint pen India ink composition.The ballpoint pen made from aqueous ballpoint pen India ink of the present invention has good writing quality, and color and luster is dark, coloured light can be selected, and has excellent anti-drying and resistance to elevated temperatures simultaneously.In the process of depositing of raising one's hat, the vaporization losses of moisture does not have dyestuff yet and separates out.Ballpoint pen raise one's hat under 25 ℃ and 50% relative humidity condition horizontal positioned 14 days or 65 ℃ of bakings of ballpoint pen band cap after 7 days initial 5cm still can keep fluent writing.
Following case description implement mode of the present invention, these examples are to be used for describing of the present invention, and should not be construed as any specific material of restriction and condition.
