Description
Technical field
The present invention relates to a kind of dumb light aqueous transfer coating and preparation method thereof.
Background technology
Modern packaging increasingly pursues personalization, wherein has the In Aluminium Foil Packing of matte effect with its high-end and atmospheric regarding
Sense, is increasingly welcome by market, is applied to some more and more than packagings such as the cigarette of higher gears, wine, cosmetics, food
In.This packaging majority is to use aluminium foil anti-mounting technology to be combined by adhesive with the base material such as paper or film by aluminium foil, makes aluminium foil
Dumb light visual sense is directly presented in outside packaging.But, this technique aluminium foil consumption is big and cost is high, cannot degrade, and does not meets
The main trend of modern packaging environmental protection, gradually by the replacement of the transfer aluminum plated technique of cost more advantage, i.e. uses dumb light transfer
Aluminizer is packed.
The prevailing technology that the transfer coatings of matt transferring aluminum-plating film is current is by adding flatting silica in transfer coatings
(such as delustring wax, silicon dioxide powder etc.) realize matte effect, and its deficiency is due to flatting silica particle and gathering in transfer coatings
The polymer resin compatibility is the best easily there is lamination, it is impossible to store for a long time, can only now with the current, add production exercise workmanship
Sequence, also control to production technology are had higher requirement, and earlier patent application CN 102367348 A is above-mentioned situation.
Although earlier application CN 103360934 A discloses a kind of aqueous mute silver transfer coatings and preparation method thereof, but it uses gas phase
Aluminium oxide, ethanol and water are mixed to get mute slurry, substantially still use the additional quenching matter incompatible with resin to obtain mute
Light effect, it is impossible to fundamentally solve long-term storage problem；Turn although CN 105462471 A discloses a kind of aqueous from delustring
Shifting aluminium-plating coating, but the resin that two kinds of compatibilitys of dependence are bad (aqueous polyurethane emulsion B and waterborne polyurethane modified propylene
Acid) obtain matte effect, although its long term storage stability can than CN 102367348 A Yu CN 103360934 A
Improve, but still more than 6 months shelf appeal steady in a long-term cannot be met.
Summary of the invention

Second aspect, the present invention provides the preparation method of a kind of described dumb light aqueous transfer coating, comprises the steps:
By waterborne polyurethane resin, dispersing aid mix homogeneously, obtain mixture A；
In mixture A, add aqueous dumb light resin, water, mix homogeneously, obtain mixture B；
In mixture B, add auxiliary agent again, filter after mix homogeneously, obtain described dumb light aqueous transfer coating.
Preferably, the mode of described mix homogeneously is stirring；It is further preferred that the time of stirring is 15～30 minutes.
Preferably, aqueous dumb light resin, water add under agitation；It is further preferred that the speed of described stirring
Degree is 500～800rpm, and the lowest then dispersion effect of mixing speed is the best and efficiency is on the low side, too high, may bring breakdown of emulsion problem.
Preferably, the described size filtering employing screen is 80～120 mesh, filters mesh too small (aperture is excessive) and does not has
Good filter effect, the excessive then filter efficiency of mesh the lowest (speed is the slowest).
Preferably, described preparation method completes in a kettle..
Preferably, described preparation method also includes the step packing gained dumb light aqueous transfer coating.
Compared with prior art, the present invention has a following beneficial effect:
(1) eliminating flatting silica, the present invention is that a kind of aqueous not using flatting silica to realize matte effect transfer dumb light is coated with
