Abstract
The invention discloses an aqueous pigment gel ink. According to weight percent, the gel ink comprises 1.0 to 10.0 percent of dispersible pigment, 0.1 to 10.0 percent of polycarboxylate, 1.0 to 5.0 percent of thickening agent, 10.0 to 35.0 percent of humectant, 0.5 percent of sterilization mildew inhibitor, 3.0 percent of pH regulator, 1.0 percent of surface active agent and 39.0 to 61.1 percent of deionized water. The aqueous pigment gel ink containing polycarboxylate can effectively improve the stability of pigment ink and increases the adhesive force between the ink and paper, thereby increasing the water resistance, light fastness and dispersion stability of products; moreover, the gel ink can solve the technical problems of the prior pigment type ink including easy delaminating precipitation and poor storage stability, and can effectively ensure that no ink interruption and pen blockage occurs during writing.
Description
Technical field:
The present invention relates to ink, particularly a kind of water-based paint Neutral writing ink and manufacture method thereof.
Background technology:
The colorant of ink mainly divides dyestuff and pigment two classes.Wherein, dye-type soluble in water, so make it can't have excellent water tolerance comparatively speaking, the documents of being write contacts with water, and dyestuff will be dissolved again, makes that the writing lines are smudgy, even decolouring and influence result of use.The photostabilization of dyestuff is poor simultaneously, and fadedness is fairly obvious after illumination, can not be used for filing and preserve.
The great advantage of pigment colorant is color fastness to water and the light fastness that it is good.But pigment ink has particle size because of its pigment, and influences its perviousness, and layering and precipitating very easily simultaneously causes the stability of ink difference and can not use.
Summary of the invention:
The invention provides a kind of aqueous pigment ink and manufacture method thereof, can solve the existing easy layering and precipitating of pigment ink, ink package stability technical problem, and do not cut off the water supply can effectively guarantee to write the time, stifled pen.
The present invention comprises pigment dispersion 1.0%-10.0%, polycarboxylate 0.1%-10.0%, thickening material 1.0%-5.0%, wetting Agent for Printing Inks 10.0%-35.0%, biocide mildewcide 0.5%, PH conditioning agent 3.0%, tensio-active agent 1.0% and deionized water 39.0%-61.1% according to weight percent.
The water-base ink that contains polycarboxylate of the present invention can improve the stability of paint ink effectively, increases ink and paper ground sticking power, and then water tolerance, photostabilization and the dispersion stabilization of increase product.
Embodiment:
Water-based paint Neutral writing ink mill base, it comprises: polycarboxylate, pigment dispersion and aqueous solvent, being applied to aqueous solvent of the present invention can be water.
In addition, can also comprise according to the ink that purpose of the present invention proposed: relevant additives such as tensio-active agent, adhesive agent, thickening material, PH conditioning agent, wetting Agent for Printing Inks, anticorrosion and bactericidal agent, so that form preferred embodiment of the present invention.
The preferred addition of the polycarboxylate among the present invention is 0.1%-10.0% (weight percent); The particle size of preferred pigment dispersion is less than 1.0 μ m, and addition is about 1.0%-15.0%.Preferred thickening is the composite resin of alkali thickening, and its purpose is to make the viscosity of ink reach certain numerical value.Preferred wetting Agent for Printing Inks is the complex solvent of polyvalent alcohol, is not volatile water-soluble organic compounds, and as ethylene glycol, glycerine, polyvalent alcohol etc., the preferred addition of wetting Agent for Printing Inks is 10.0%-35.0%.In addition, in ink of the present invention, preferably also add sterilant and PH conditioning agent.Sterilant can suppress bacterium to be grown in ink, and the PH conditioning agent can adjust suitable substance P H value, makes colorant show the ideal colour system.
The present invention, according to weight percent, comprise pigment dispersion 1.0%-10.0%, polycarboxylate 0.1%-10.0%, thickening material 1.0%-5.0%, wetting Agent for Printing Inks 10.0%-35.0%, biocide mildewcide 0.5%, PH conditioning agent 3.0%, tensio-active agent 1.0% and deionized water 39.0%-61.1%.This pigment dispersion is a carbon black, and its particle is less than 1.0 μ m; Wetting Agent for Printing Inks is ethylene glycol or glycerine; Thickening material is the acrylic resin of alkali thickening; Tensio-active agent is the tensio-active agent of the polyethenoxy ether class of non-ionic type; Biocide mildewcide is the biocide mildewcide of Polyphenols.
Preferred thickening is the composite resin of alkali thickening, and its purpose is to make the viscosity of ink reach certain numerical value.Preferred wetting Agent for Printing Inks is for not volatile water-soluble organic compounds, as ethylene glycol, glycerine, polyvalent alcohol etc.In addition, in ink of the present invention, preferably also add sterilant and PH conditioning agent.Sterilant can suppress bacterium to be grown in ink, and the PH conditioning agent can adjust suitable substance P H value, makes colorant show the ideal colour system.
The preferred embodiment prescription is as follows:
The stability of ink test is that the check ink guarantees the stay-in-grade ability within a certain period of time, and paint ink was stored one to three months under 45 ℃ of temperature, surveys its viscosity and pH value and changes.The said products after tested, excellent in stability is preserved three months its viscosity in the time of 45 ℃.PH value is constant substantially, does not have precipitation.
Water-proof test is the ability of check ink opposing water logging, with a certain amount of water of spray on the ink writing, at the regular hour point, observes the degree that ink melts, and the degree that melts represents that the more water tolerance is poorer.After testing, water-base ink writing of the present invention is clear, water-tolerant.
The light permanency test is the ability of check ink writing opposing ultraviolet lighting.After testing, the sun-resistant fastness of ink of the present invention is 8 grades, can be used as files and writes.
The above results illustrates the water-base ink that contains polycarboxylate of the present invention, can improve the stability of paint ink effectively, increases ink and paper ground sticking power, and then increases water tolerance, photostabilization and the dispersion stabilization of product.
Method feature of the present invention is its method of manufacturing technology.It is characterized in that earlier pigment, dispersion agent, solvent etc. being reached dispersing and mixing after colloidal mill grinds, behind high speed sand mill sand milling 6-8h, obtain the mill base mother liquor again, add mixed dilutings such as wetting Agent for Printing Inks, thickening material, antimildew disinfectant again and form.
