Abstract
The invention discloses an aqueous anti-counterfeiting stamp ink with stronger anti-counterfeiting performance. The aqueous anti-counterfeiting stamp ink comprises the following components in percentage by weight: 60%-70% of aqueous polyurethane, 15%-25% of infrared transformed fluorescent powder, 1%-2% of super-concentrated slurry, 6%-8% of light calcium carbonate, 6%-8% of polyethylene wax and 2%-4% of mineral oil. The aqueous anti-counterfeiting stamp ink has the advantages of stable stamping performance, good detection on information provided by anti-counterfeiting feature substances, long-term preservation and rapid and accurate true and false discrimination by adopting a discriminating system for collecting stamp features.
Description
Technical field
The present invention relates to anti-counterfeiting stamp ink material field, more particularly, relate to a kind of water-based stamp-pad ink with stronger antifalsification.
Background technology
Stamp-pad ink comprises ink paste, ink pad stamp-pad ink and atomic seal ink (comprising osmosis type and solid type).Stamp-pad ink is false proof to be realized by attaching detectable substance in the stamp-pad ink.Relatively successful stamp-pad ink anti-counterfeiting technology comprises at present:
Fluoresent printing ink, optical disclour printing ink, temperature sensitive ink, wet quick printing ink, infrared excitation printing ink, daylight color shifting ink, watermark printing ink, magnetic ink, hollow out are destroyed printing ink, chemical stain printing ink, pressure-sensitive color shifting ink, mirror image color shifting ink etc.
At common stamp-pad ink, in a single day above-mentioned stamp-pad ink is false proof all to have stronger antifalsification, yet obtains corresponding detectable substance, and its seal all can be copied to some extent.If in common stamp-pad ink, add detectable substance, as thermochromic material or Ultraluminescence, imitated temperature-sensitive anti-counterfeiting stamp ink or Ultraluminescence anti-counterfeiting stamp ink, the seal of this counterfeit stamp-pad ink has fluorescigenic characteristic under the thermo-color of chance or the ultra violet lamp equally.In this case, be difficult to judge the true and false by thermal source or ultraviolet lamp.Therefore, the information of relevant detectable substance must have singularity in the anti-counterfeiting stamp ink, must have corresponding identification measure.If this information is disclosed, the identification measure corresponding with it is also just nonsensical.Because it is a lot of to have the false proof material of Ultraluminescence, whether fluoresce if only detect seal. so, this identification measure is easy to occur erroneous judgement.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiencies in the prior art, and a kind of aqueous anti-counterfeiting stamp ink with stronger antifalsification is provided.
Aqueous anti-counterfeiting stamp ink of the present invention, be achieved by following technical proposals, form according to described mass percent: aqueous polyurethane 60-70%, infrared up-conversion phosphor 15-25%, the slurry 1-2% of hyperconcentration group by following component, light calcium carbonate 6-8%, polyethylene wax 6-8%; Dormant oils 2-4%.
Described infrared up-conversion phosphor is last conversion 980nm infrared excitation visible green fluorescent material.
The marking stable performance of aqueous anti-counterfeiting stamp ink of the present invention, anti-counterfeiting characteristic material provide information detection property good, but prolonged preservation, recognition system is gathered marking feature, and it is rapid, accurate to discern the false from the genuine.Infrared up-conversion phosphor is that organic polymer is synthetic, has very good perviousness, stability and quick-drying; Free settling not, the high trace long preservative period of colour density, seal is clear evenly, and the paper of not spreading and sinking in spreads little.Seepage velocity is fast, and transfer performance is good, and outward appearance is gorgeous, the trace indiffusion; Under the irradiation of the infrared lamp of wavelength 980nm, produce bright-coloured green fluorescence, fluorescence radiation intensity height, differentiability are good.General ultraviolet anti-counterfeiting stamp ink and temperature sensitive ink antifalse effect can only be preserved about 12 months, and have degradation period.And infrared up-conversion phosphor is because the rare earth element good stability, and the antifalse effect preservation period can prolong greatly, accomplishes in 5 years effectively.General ultraviolet anti-counterfeiting stamp ink scientific and technological content is few, and it is low to make threshold, can be copied at present, and the infrared excitation anti-counterfeiting stamp ink adopts infrared up-conversion phosphor false proof, and anti-counterfeiting performance is outstanding, and it is higher to make threshold, is difficult for being copied.
Aqueous polyurethane occurs as solvent among the present invention, too much can weaken infrared up-conversion phosphor brightness, very fewly can not fully dissolve each component, through test 60-70% the best, hyperconcentration group slurry occurs as adhesion agent, because degree of enrichment is bigger, using too much to make stamp-pad ink solidify, used that I haven't seen you for ages and produce sedimentation phenomenon, polyethylene wax improves pigment-dispersing, infrared up-conversion phosphor is effectively disperseed and improves gloss and stereoscopic sensation, Dormant oils is as thinner, auxiliary solvability and the viscosity of going up the conversion powder of adjusting, light calcium carbonate improves the pigment fastness to rubbing, and excessive meeting makes the stamp-pad ink granular sensation overweight, I haven't seen you for ages shortens the stamp-pad ink preservation period for amount, determine the slurry 1-2% of hyperconcentration group, light calcium carbonate 6-8%, polyethylene wax 6-8% through repeatedly testing; The proportioning of Dormant oils 2-4% can reach not free settling of anti-counterfeiting stamp ink of the present invention, the high trace long preservative period of colour density, and seal is clear evenly, and the paper of not spreading and sinking in spreads little; Seepage velocity is fast, and transfer performance is good, and outward appearance is gorgeous, the trace indiffusion.
