Abstract
The invention discloses an erasable gel-ink pen ink and a preparation method thereof. The ink at least consists of 45 to 55 percent of acrylic resin liquid, 10 to 15 percent of pigment, 15 to 20 percent of ethanol, 10 to 15 percent of deionized water, 8 to 12 percent of deaerating agent WGL and 1 to 2 percent of defoamer, with the percentage being as weight percentage. The preparation method includes the steps of: dissolving the pigment in an ethanol solution, using a grinder for grinding fully and filtering the mixture, obtaining the pigment ethanol solution, and finally mixing the pigment ethanol solution and the acrylic resin liquid, deaerating agent WGL, the defoamer and the deionized water fully to be dispersed for 1 to 1.5 hours by ultrasonic to prepare the erasable gel-ink pen ink. The prepared ink has the advantages of being smooth in writing, erasable in ink mark convergence, even in ink flow, long in decapping time, etc.; the written handwriting is waterproof, sun proof and long in preserving time.
Description
Technical field
The present invention relates to a kind of gel ink pen ink and preparation method thereof of wiping.
Background technology
Gel ink pen is a kind of writing implement of popular in the world at present, because this writing implement has much advantage, its distinctive feature is arranged, and is known as cross-centennial writing implement.Gel ink pen is a color base according to the ink and the employing pigment of its simple sign an undertaking structure, medium viscosity, make write lubricated smooth, the ink marks convergence is strong, can do permanent preservation, it is even also to have ink flowrate simultaneously, the characteristics of the time length of raising one's hat, its physicochemical property are much higher than oiliness and aqueous ballpoint pen uses the interface.Can wipe gel ink pen and be the novel kind in the gel ink pen series products,, have correctability again, use common stationery rubber just can easily wipe change again and write literal with the advantage of gel ink pen.Because the keying action that the gel ink pen ink is risen in gel ink pen, the simplification that should adapt to a tool effectively has the unicity of mating with nib again, and can wipe the gel ink pen ink because technical complexity, the technic index uniqueness has increased the difficulty that ink is researched and developed greatly.
Summary of the invention
Purpose of the present invention just provides a kind of gel ink pen ink and preparation method thereof of wiping, this ink is the pigment style Neutral writing ink, have and write lubricated smooth, ink marks convergence and can wipe and advantage such as change, all even time of raising one's hat of ink flowrate is long, the writing that writes out is water-fast, sun-proof, shelf time is long, and the preparation method is simple.
Realize that the technical scheme that the object of the invention adopts is: a kind of gel ink pen ink of wiping, ink is at least by 45～55% acrylic resin liquid, 10～15% pigment, 15～20% ethanol, 10～15% deionized water, 8～12% air release agent WGL and 1～2% defoamer are formed, and above per-cent is weight percentage.
The described preparation method who wipes the gel ink pen ink may further comprise the steps: get 45～55% acrylic resin liquid by weight percentage, 10～15% pigment, 15～20% ethanol, 10～15% deionized water, 8～12% import air release agent WGL, 1～2% defoamer, then pigment is dissolved in ethanolic soln, grind abundant after-filtration through sand mill and get the pigment ethanolic soln, at last pigment ethanolic soln, acrylic resin liquid, air release agent WGL, defoamer and deionized water thorough mixing can be wiped the gel ink pen ink after ultrasonic dispersing promptly made in 1～1.5 hour.
The gel ink pen ink of wiping provided by the invention has the following advantages:
1.PH value is 7.8～8.6, is slight alkalinity, to the stability of ink and to the corrodibility generation effect of nib.
2. black 2500～3000CP, adjustable extent is wide, adjusts in the time of can reflecting when the winter summer temp changes.
3. have the surface tension of 30～38 dynes per centimeter, adjustable extent is wide, can require to adjust erasability according to difference.
4. thixotropy is 2.4～4.4, directly reflects i.e. nib the giving full play at static excellent handle viscosity, surface tension, fluency when these several states of speed are changed when writing between state and write of ink.
5. tolerable temperature is-25～60 ℃, and is applied widely.
6. has stronger dry resistance.
