Abstract
The invention relates to black gel ink for gel ink pens and a method for preparing the black gel ink. The black gel ink for gel ink pens is characterized by being mainly made of color black, propylene glycol, styrene-acrylate copolymer sodium salt, ethylene glycol, crosslinked acrylate copolymer sodium salt, sodium benzoate, benzotriazole, xanthan gum, softened water and the like. The black gel ink for gel ink pens has the advantages of high writing stability, uniformity in ink outlet rheology, high writing fluency durability and the like.
Description
Technical field
The present invention relates to a kind of black gel ink pen ink and preparation method thereof, belong to the writing ink field.
Background technology
China is gel ink pen big producing country; Its output occupies the first in the world always; But the core material-Neutral writing ink that is used for gel ink pen up to now is dependence on import still; And the price of import Neutral writing ink is high always, causes China's system sustained development of enterprises to obtain hindering, and has also restricted China simultaneously by a system big country striding forward to system pen power.Therefore, research and solution Neutral writing ink prepare the technical bottleneck in the process, realize that the production domesticization of high-quality Neutral writing ink is significant to the sound development that promotes China's gel ink pen industry.
The tradition ballpoint pen belongs to solvent type ink with ink; Be insoluble in water and have slight irritating smell, and mostly the oiliness ball pen ink is dye-type, can on absorption interface and non-absorption interface, write; The writing that forms be difficult for being wiped and but be prone to oxidizedly, not can be used as file records and use.Simultaneously, because of oiliness ball pen ink viscosity is high, cause ballpoint pen when writing, to exist black undercurrent smooth, it is poor to write the effort feel, goes out problems such as the China ink amount is inhomogeneous; Aqueous ballpoint pen uses the water-based ink, and paper is strong to its adsorptivity, has problems such as surperficial anchorage difference is prone to wipe when writing at non-absorbing material interface.
The appearance of Neutral writing ink has overcome the defective of above two kinds of lettering pen tools; Neutral ballpoint pen characteristic circle is between oiliness ballpoint pen and aqueous ballpoint pen; It write principle with above-mentioned two kinds the same; But in using, the requirement of property ink is very high, particularly the dispersiveness of Neutral writing ink, thixotropy etc. all had very high requirement.
The present invention is exactly the problem and the defective that will overcome and solve above-mentioned existence, and a kind of Neutral writing ink of writing good stability, going out characteristics such as black rheology is even, fluent writing, weather resistance height that has is provided.
Summary of the invention
To the effect that of the present invention: this black gel ink pen ink mainly by: colour black, Ucar 35, styrene-propene hydrochlorate multipolymer sodium salt, terepthaloyl moietie, cross-linked acrylic acid salt copolymer sodium salt, Sodium Benzoate, benzotriazole, XG 550, softening water etc. are formed.
By being: colour black 2.0～6.0 with mass percent; Ucar 35 8.0～12; Styrene-propene hydrochlorate multipolymer sodium salt 1.0～3.0; Terepthaloyl moietie 2.0～6.0; Cross-linked acrylic acid salt copolymer sodium salt 1.0～4.0; Sodium Benzoate 0.5～2.0; Benzotriazole 0.2～1.0; XG 550 0.1～1.0; Softening water 65～80 is formed.
Its preparation method is: under agitation in a little softening water, add XG 550, get clear solution; Colour black, styrene-propene hydrochlorate multipolymer sodium salt and surplus water are added in the above-mentioned glue through the suspension-s that high-speed stirring is processed, mix, be dispersed to fineness with sand mill and be less than or equal to 5 μ m; Move under the impeller; Add other component and dissolving, continue 1h, regulate pH value to 8.0 with sodium hydroxide solution; Filter, promptly get black gel ink pen ink in the package encapsulation container of packing into after the assay was approved.
The practical implementation method
1, takes by weighing colour black 4.0 by mass percent respectively; Ucar 35 10.0; Vinylbenzene-
Acrylate multipolymer sodium salt 1.0; Terepthaloyl moietie 5.0; Cross-linked acrylic acid salt copolymer sodium salt 2.0; Sodium Benzoate 1.0; Benzotriazole 0.5; XG 550 0.2; Softening water 75.3, for use.
2, under agitation in 35% softening water, add XG 550, get clear solution; Colour black, styrene-propene hydrochlorate multipolymer sodium salt and surplus water are added in the above-mentioned glue through the suspension-s that high-speed stirring is processed, mix, be dispersed to fineness with sand mill and be less than or equal to 5 μ m; Move under the impeller; Add other component and dissolving, continue 1h, regulate pH value to 8.0 with sodium hydroxide solution; Filter, promptly get black gel ink pen ink in the package encapsulation container of packing into after the assay was approved.
