Description
Technical field
The present invention relates to direct liquid type water pen ink, relate in particular to a kind of nano level direct liquid type water pen ink and manufacture method thereof, belong to the ink technology field.
Background technology
Aqueous pen in direct liquid type is the new class product that a system industry is developed in recent years, the basic dependence on import of supporting with it direct liquid type water 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 direct liquid type water pen ink is: the water of spreading and sinking in, light fugitive, fade easily, and can not long term archival preserve; The easy crystallization of dye component causes China ink uneven, writes not smooth; Poisonous, not environmental protection.
The pigment style direct liquid type water pen ink can effectively overcome above-mentioned shortcoming, pigment ink is scattered in the ink system equably with particle and makes it painted, but common pigment style direct liquid type water pen ink is because pigment particles is big, and dispersion effect is poor, can not reach the ideal writing effect.A kind of nano-level pigment-type direct liquid type water pen ink can overcome above-mentioned deficiency preferably, but along with diminishing of size of particles, specific surface area will increase greatly, it is big that Van der Waals force between the particle will become, very easily produce cohesion between micropartical, thereby cause in storage process, producing 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 keeping low viscous stablizing is again an important indicator, because direct liquid type water pen ink is directly to add in the aqueous pen in direct liquid type spare, so, have relatively high expectations; Viscosity is bigger than normal slightly, will influence the China ink amount, causes and writes not smooth or broken string, and viscosity is low excessively, the ink leak phenomenon can occur again.But in process of production, elongated along with the increase of grinding rate and time, the viscosity of ink system will become greatly, and keeping low viscosity and being controlled at is the another important technology difficult point of direct liquid type water pen ink more among a small circle.So, produce desirable high quality nanometer level direct liquid type water pen ink, be the important technology problem that is worth research.
Summary of the invention
The purpose of this invention is to provide a kind of direct liquid type water pen ink and manufacture method thereof, adopt " superfine grinding technology " and " scientific formula ", be intended to effectively solve particle diameter, viscosity, the storage layering of direct liquid type water pen ink pigment and write technical problems such as infiltration, be fit to the pigment style aqueous pen in direct liquid type, can mate various aqueous pen in direct liquid type spares.
Purpose of the present invention is achieved through the following technical solutions:
Direct liquid type water pen ink is characterized in that its component has following weight percent: pigment 3.0～10.0%, resin 3.0～8.0%, solvent 10.0～20.0%, dispersion agent 2.0～5.0%, wetting Agent for Printing Inks 2.0～10.0%, sterilant 0.1～0.3%, deionized water 79.9～46.7%.
Further, above-mentioned direct liquid type water pen ink, described pigment be deceive, a kind of in red, blue, green, yellow five base colors of pigment, be the P.Bk.7 black pigment, it perhaps is any one red pigment in the middle of the P.R.48:2/P.R.48:3/P.R.53:1/P.R.112/P.R.170/P.R.213/P.R.2 54, perhaps be any one blue look pigment in the middle of the P.B.15/P.B.15:1/P.B.15:3/P.B.60, or P.G.7 veridian, or any one yellow ultramarine in the middle of the P.Y.74/P.Y.93/P.Y.150; Described resin is a water-borne acrylic resin; Described solvent is ethylene glycol or glycerol; Described dispersion agent is the polymkeric substance macromolecule dispersing agent; Described wetting Agent for Printing Inks is polyoxyethylene glycol or glycol ethers.
Again further, above-mentioned direct liquid type water pen ink, its component has following weight percent: pigment 6.5%, water-borne acrylic resin 5.5%, ethylene glycol 15%, polymkeric substance macromolecule dispersing agent 3.5%, polyoxyethylene glycol 6%, sterilant 0.2%, deionized water 63.3%.
Again further, the manufacture method of above-mentioned direct liquid type water pen ink, it is characterized in that: deionized water is added in the pre-dispersed pot earlier, add solvent, dispersion agent, resin, wetting Agent for Printing Inks, sterilant successively under stirring, even up to whole dissolvings, add pigment at last, after fully mixing, carried out superfine grinding then 4～12 hours, the granularity that makes granules of pigments is the nano level specification, stop to grind discharging.
Further, the manufacture method of above-mentioned direct liquid type water pen ink, the particle diameter after described granules of pigments grinds is D
50=100～200 nanometers.
Further, the manufacture method of above-mentioned direct liquid type water pen ink, earlier deionized water is added in the pre-dispersed pot, stir and add ethylene glycol, polymkeric substance macromolecule dispersing agent, water-borne acrylic resin, polyoxyethylene glycol, sterilant down successively, even up to whole dissolvings, add pigment at last, after fully mixing, carried out superfine grinding then 8 hours, and made the granularity D of granules of pigments
50=150 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 the superfine grinding technology, make the granules of pigments median size reach 100～200 nanometers.Adopt the polymkeric substance macromolecule dispersing agent, can be dissolved in fast in the solvent, significantly reduce the viscosity of dispersion system in the particulate process of lapping, improve the pigment particles wetting property, shorten the granules of pigments milling time, improve the dispersion stabilization in the long-time storage process of pigment dispersion system;
2. the unique scientific formula of utilization makes ink have good dispersion stabilization and lower viscosity;
3. the ink lovely luster, go out China ink evenly, fluent writing, the long-term storage steady quality, not stratified, do not precipitate, sun-proof, water-repellancy extra-heavy, colour-fast, writing can prolonged preservation;
4. ink PH is neutral, and is less to nib corrodibility;
5. ink normal temperature of the present invention raise one's hat reach 30 days, high temperature raise one's hat for 50 ℃ reach 15 days, normal temperature block is after 1 year, all can normally write; In following 1 year of the barreled ink normal temperature, layering, separation, precipitation iso-metamorphism phenomenon do not appear;
6. extensively be fit to the pigment style aqueous pen in direct liquid type, can mate various aqueous pen in direct liquid type spares.
