Abstract
The invention relates to ink, in particular to alcohol soluble erasable pigment ink and a preparation method thereof. The erasable pigment ink includes the following components by weight percent: 3.0-17.0 of dispersible pigment, 0.2-15 of release agent, 8-16 of alcohol soluble solvent, 3-10 of humectant, 0.3 of PH conditioning agent, 3 of surface active agent and 39.7-78.5 of alcoholic solvent. The preparation steps are as follows: firstly, the dispersible pigment, the surface active agent, the release agent and the alcohol soluble solvent are dispersed and mixed at high speed and are processed by a high-pressure collider to obtain a mother solution, and the humectant and the PH conditioning agent are added to and mixed with the mother solution; and finally, the erasable pigment ink can be obtained after dilution. The invention can thoroughly prevent the existing pedagogical chalks from harming the health, and has the characteristics of immediate erasing, erasable long-term board remaining, no discolourment under long-term sunlight illumination, repeatable writing and beautiful color.
Description
Technical field:
The present invention relates to ink, particularly a kind of pure dissolubility erasable pigment ink and manufacture method thereof.
Background technology:
Teaching, teaching, still prolong in decades in China and to commonly use chalk as writing implement, along with social progress, people more and more pay attention to healthy and environmental protection, write the pollution of wiping the examination dust for solving chalk, need to adopt the novel writing implement environment friendly and pollution-free, that color is more gorgeous.
The great advantage of erasable pigment China ink is: liquid ink, but the writing that forms after writing can be wiped to the greatest extent immediately, Palingraphia leaves no trace; There are not irritating smell, dust and obnoxious flavour; The long-term reservation of ink marks can not faded, and ink marks stays plate still to keep erasable performance for a long time.
Summary of the invention:
The invention provides a kind of erasable pigment ink and manufacture method thereof.Can thoroughly solve existing teaching with the injury of chalk to health, but and have immediately can wipe, stay for a long time that plate can be wiped, the long-term colour-fast Palingraphia of illumination, characteristic beautiful in colour.
For solving above technical problem, the present invention is achieved in that
A kind of erasable pigment ink is characterized in that it comprises pigment dispersion 3.0-17.0%, stripper 0.2～15% and pure soluble solvent 8%-16%, wetting Agent for Printing Inks 3-10%, PH conditioning agent 0.3%, tensio-active agent 3% and alcoholic solvent 39.7-78.5% according to weight percent.
Described erasable pigment ink is characterized in that this alcohol soluble solvent is an ethanol.
Described erasable pigment ink is characterized in that this stripper is a cithrol.
Described erasable pigment ink is characterized in that this wetting Agent for Printing Inks is a Macrogol 200.
Described erasable pigment ink is characterized in that this PH conditioning agent is a trolamine.
Described erasable pigment ink is characterized in that this tensio-active agent is polyxyethylated phosphoric acid ester.
Described erasable pigment ink, the particle size that it is characterized in that the addition of this pigment dispersion is 100-200nm.
A kind ofly be used to make the method for erasable pigment ink as mentioned above, it is characterized in that the steps include: earlier pigment dispersion, tensio-active agent, stripper, pure soluble solvent high speed dispersion being mixed, handle through the high pressure collider again and obtain mother liquor, add wetting Agent for Printing Inks again, PH conditioning agent mixed diluting forms.
Specific implementation method:
The invention discloses a kind of erasable pigment ink, it comprises pigment dispersion 3.0-17.0%, stripper 0.2～15% and pure soluble solvent 8%-16%, wetting Agent for Printing Inks 3-10%, PH conditioning agent 0.3%, tensio-active agent 3% and alcoholic solvent 39.7-78.5% according to weight percent.
Wherein: this wetting Agent for Printing Inks can be high molecular polymer, and this alcohol soluble solvent can be ethanol, and this stripper is a cithrol, and this wetting Agent for Printing Inks is a Macrogol 200, and this PH conditioning agent is a trolamine, and tensio-active agent is polyxyethylated phosphoric acid ester.
The particle size of the addition of this pigment dispersion is 100-200nm.
The manufacture method of erasable pigment ink as mentioned above, the steps include: earlier pigment dispersion, tensio-active agent, stripper, pure soluble solvent high speed dispersion to be mixed, handle through the high pressure collider again and obtain mother liquor, add wetting Agent for Printing Inks again, PH conditioning agent mixed diluting forms.
The preferred addition of the stripper among the present invention is 0.2%-15.0% (weight percent), can wipe even make ink write the back; The particle size of preferred pigment dispersion is 100-200nm, and addition is about 3.0%-17.0%, guarantees that ink has than the high light-fast grade; Preferred wetting Agent for Printing Inks is not volatile pure soluble macromolecular polymkeric substance, and preferred addition is 3.0%-10.0%, makes the cap time of not doing of opening of pen reach 8 hours at least.In addition, in ink of the present invention, preferably also add the PH conditioning agent.The PH conditioning agent can adjust suitable substance P H value, improves and a written performance of joining, and 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 six months under 50 ℃ of temperature, surveys its viscosity and pH value and changes.The said products after tested, excellent in stability is preserved six months its viscosity, pH value is constant substantially, does not have precipitation in the time of 50 ℃, and control group was reunited at 50 ℃ in following 10 days, viscosity rises.
The light permanency test is the ability of check ink writing opposing ultraviolet lighting.Through the test of national product quality monitoring testing station, the sun-resistant fastness of ink of the present invention is 6 grades.
The The above results explanation pure dissolubility erasable ink that contains stripper of the present invention, can reduce the clinging power of ink and bright and clean plate (paper) face effectively, ink marks can be wiped easily, even if stay plate can not change greater than 30 days performances, ink marks can not produce bonding with plate, but and Palingraphia.Simultaneously, contain the tensio-active agent that adapts with ink system among the present invention, and then be added to the dispersion stabilization of ink.
Method feature of the present invention is its method of manufacturing technology.It is characterized in that elder generation with high speed dispersing and mixing such as pigment, tensio-active agent, stripper, solvents, handle (being forced into 10000-12000t/m again through the high pressure collider
2Bump is pulverized) obtain mother liquor, add mixed dilutings such as wetting Agent for Printing Inks, PH conditioning agent again and form.
In sum, though the present invention has as above described preferred embodiment, they are not to be used for limiting the present invention, and protection scope of the present invention should be as the criterion with the scope that claim of the present invention was defined.
