Description
Technical field
The present invention relates to white board pen ink, relate in particular to a kind of nano-level pigment-type white board pen ink and manufacture method thereof, belong to the ink technology field.
Background technology
The blank pen is the new class product that a system industry is developed in recent years, the basic dependence on import of supporting with it white board pen ink.Hang Xiao high-grade special-purpose ink is all being changed to pigment style by dye-type in the market.The shortcoming of dye-type white board pen ink is: the easy crystallization of dye component, and cause China ink inhomogeneous, write not smooth; Poisonous, not environmental protection.
The pigment style white board pen ink is to be scattered in the ink system with pigment particles it is effective.Common pigment style white board pen ink pigment particles is big, and dispersion effect is poor, and directly influence is write.A kind of nano-level pigment-type white board pen ink can overcome above-mentioned deficiency effectively.But along with diminishing of particle, specific surface area will increase greatly, and the Van der Waals force between the particle will become greatly, very easily produce cohesion between micropartical, thereby cause producing in storage process layering, precipitation iso-metamorphism phenomenon.General Technology and equipment are difficult to make that pigment particles reaches initial nanometer in the ink system, are difficult to the dispersion stabilization that keeps good.Moreover, keep low viscous stable be again an important index, viscosity is bigger than normal, it is little to use black quantitative change, causes phenomenons such as writing smooth, broken string, wire drawing; Viscosity is too little, the ink leak phenomenon can occur, and keeping low viscosity is another technical barrier of white board pen ink.So, produce desirable high quality nanometer level pigment style white board pen ink, in preparation, must capture above technical problem.
Summary of the invention
The purpose of this invention is to provide a kind of white board pen ink and manufacture method thereof, adopt " superfine grinding technology " and " scientific formula ", be intended to effectively solve particle diameter, viscosity, the cohesion layering of white board pen ink pigment and write erasability, technical problem such as raise one's hat, make it can mate various homemade, import rolled cores and fiber nib.
Purpose of the present invention is achieved through the following technical solutions:
White board pen ink is characterized in that its component has following weight percent: pigment 3.5～5.0%, the agent 1.0～5.0% of raising one's hat, ethanol 48.0～71.0%, propyl alcohol 15.0～25.0%, but liniment 5.0～10.0%, resin 3.5～5.0%, dispersion agent 1.0～2.0%.
Further, a kind of in black, red, blue, green four base colors of pigment of above-mentioned white board pen ink, described pigment; The described agent of raising one's hat is the how pure lipoid of long carbochain; But described liniment is long chain fatty acid fat; Described resin is polyvinyl butyral acetal (PVB); Described dispersion agent is the polymkeric substance macromolecule dispersing agent.
Again further, above-mentioned white board pen ink, its component has following weight percent: pigment 4.25%, the how pure lipoid 3.0% of long carbochain, ethanol 59.5%, propyl alcohol 20.0%, long chain fatty acid fat 7.5%, polyvinyl butyral acetal 4.25%, polymkeric substance macromolecule dispersing agent 1.5%.
Again further, the manufacture method of above-mentioned white board pen ink, it is characterized in that: earlier ethanol, propyl alcohol are added in the pre-dispersed pot, add raise one's hat agent liniment, resin, dispersion agent down successively but stir, even up to whole dissolvings, add pigment at last, after fully mixing, carried out superfine grinding then 20～30 hours, the granularity that makes granules of pigments is the nano level specification, stop to grind discharging.
Further, the manufacture method of above-mentioned white board pen ink, the particle diameter after described granules of pigments grinds is D
50=100～200 nanometers.
Further, the manufacture method of above-mentioned white board pen ink, earlier ethanol, propyl alcohol are added in the pre-dispersed pot, stir and add the how pure lipoid of long carbochain, long chain fatty acid fat, polyvinyl butyral acetal (PVB), polymkeric substance macromolecule dispersing agent down successively, even up to whole dissolvings, add pigment at last, after fully mixing, carried out superfine grinding then 25 hours, and made the granularity D of granules of pigments
50=160 nanometers stop to grind discharging.
The outstanding substantive distinguishing features and the obvious improvement of technical solution of the present invention is mainly reflected in:
1. adopt advanced " superfine grinding technology ", make the pigment particles median size reach 100～200 nanometers, method is easy, and technology is reasonable;
2. the uses advanced scientific formula all can keep low viscosity under high temperature, low temperature, normal temperature;
3. bright in colour, go out China ink evenly, write delicate and smooth, no wire drawing sense, neat in edge;
4. long-term storage steady quality, not stratified, do not precipitate, have good dispersion stabilization, still can normally write after raising one's hat 8 hours;
5. erasability is good, writes afterwards still very easily to wipe more than 30 days, and leaves no trace;
6. be adapted at writing on any smooth clean planes such as blank, glass, plastics, can mate various homemade, import rolled cores and fiber nib, effect is good.
