Description
Technical field
The present invention relates to a kind of aqueous fluorescent anti-counterfeit paint composition of only ultraviolet identification.
Background technology
For a long time, people abhor fake and forged behavior always, in order to hit it is fake and forged also generate it is a variety of
The product such as anti-counterfeiting technology, bank note, packaging, stamp it is false proof, mainly pass through having used to Antiforge fluorescent ink in printing process
Into the use of fluoresent printing ink plays central role wherein.Fluorescent material in fluoresent printing ink mainly has as follows
It is several：1st, Inorganic fluorescent paint, its stability is good, but is difficult to disperse in oil medium；2nd, organic RE fluorescent material, it is such
Material has the advantages that preparation is simple, and dissolubility is good in oil medium, but cost is higher；3rd, organic fluorescence materials, synthesis is simple,
It is scattered in oil medium, but mostly daylight excites, and most stability are poor.Applied at present in anti-forgery ink is at most dilute
Earth metal complex compound, defect are that fluorescence intensity reduces after placing for a long time.Tetraphenylethylene (TPE) class compound is that one kind has
The organic fluorescence materials of aggregation-induced emission (AIE) characteristic, it is colourless in the solid state not to shine, when be subject to ultraviolet light (300~
The visible ray of different-waveband, and good stability can be launched when 400nm) irradiating, be easy to disperse in media as well, be it is a kind of be beneficial to it is false proof
The novel fluorescent material of effect.
In recent years, the concern of country and society to environmental problem increasingly rises, and widely using for water paint is imperative,
And aqueous fluorescent material is most at present applied to indoor paint, glo-stick etc., the fluorescent material being related to is mainly daylight excitation
Organic fluorescence thing, the aqueous anti-counterfeiting coating for not depending on ink is still commercially blank.
The content of the invention
The defects of for the prior art, the object of the present invention is to provide a kind of aqueous fluorescent anti-counterfeit paint of only ultraviolet identification
Composition, due to the poor solvent that water is tetraphenylethylene class organic compound, when system is water-based emulsion, tetraphenylethylene
The problems such as can not being dispersed in after directly being mixed with lotion in system, causing opaque coating appearance, precipitation, particle to suspend,
It can not be used as stable prod；The present invention passes through many experiments, using containing can reaction active groups (hydroxyl, carboxyl, amino)
Tetraphenylethylene, by rear reagentia by the fluorescent material uniform graft to latex particle, there is provided a kind of appearance is saturating
Bright aqueous anti-counterfeiting coating, it is apparent transparent after being coated with and has high gloss, and different ripples can be only sent under ultraviolet light
Section fluorescence, can both be coated on the base material without printing such as paperboard, lining paper, packaging material after printing can be also coated on as varnish
On, play anti-fake effect.One-pass molding of the present invention, improves production efficiency, has saved big energy, while the coating is a kind of
Environmental Protective Water-paint.The present invention still belongs to blank in package coating field at present.
The present invention is achieved through the following technical solutions：
The present invention provides a kind of aqueous fluorescent anti-counterfeit paint composition of only ultraviolet identification, the composition include component and
Percentage by weight is as follows：
Preferably, the high-temperature resistant acrylic emulsion, Gu it is between 50~60%, Tg is 90~110 DEG C to contain；It is preferred that
A1091, A662 or A639 of DSM N. V..
Preferably, the reactable acrylic emulsion, predominantly high hydroxyl value acrylic emulsion, solid containing be 40~
60%, Tg are 10~30 DEG C, and hydroxyl value is 2.0~4.0mgKOH/g；It is preferred that the AC 27401 of Opel enlightening company, AC 2597, AC
31 etc..
Preferably, the fluorescence indicator, for containing the tetraphenylethylene class chemical combination that can react hydroxyl, carboxyl or amino
Thing, such as amino TPE, carboxyl TPE, hydroxyl TPE.
Preferably, the crosslinking agent is aziridines crosslinking agent, methylol dimethicone, acrylic dimethyl-silicon
The ZC-100 of the one or more that oil collects, preferably DSM N. V..
Preferably, the defoamer is the dimethicone of fluorine richness；
Preferably, the wetting dispersing agent is polyether-modified dimethicone；
Compared with prior art, the present invention possesses following beneficial effect：
Tetraphenylethylene class compound with aggregation-induced emission characteristic is grafted to third by the present invention by crosslinked action
On latex particle in olefin(e) acid lotion, high yield (100%) transparent water-based emulsion is obtained；It is purple by tetraphenyl ethylene compound
The characteristic of outer light excitation fluorescence, makes emulsion coating have only ultraviolet light evident characteristics after forming a film.
