Description
Technical field
The invention belongs to chemical coating fields, and in particular to a kind of water-borne UV-curing vacuum plating priming paint；In addition, of the invention
Also relate to the preparation method and electric plating method of the water-borne UV-curing vacuum plating priming paint.
Background technology
UV vacuum plating coatings are a kind of new ultra-violet photocureable coating to grow up on the basis of UV plastic paints.With
The development of decorative plastic technology, a kind of plastic products metallization decoration technique generates therewith, it is to utilize plastic basis material application bottom
After paint, through vacuum plating or dash coat, one layer of metal film layer of application, re-coating finishing coat forms.It is complete by the frosting of application
Metallic luster is flickered entirely, noble and magnificent metal quality is showed, does not see it being plastic products at all.The metal of plastics
Makeup decorations can not only save the metal material of a large amount of preciousnesses, quality of item be also significantly reduced, in recent years in cosmetic package
It obtains in the manufactures such as bottle and packing box, automobile lamp, bottle package bottle cap, mobile phone plastic key, casing for clock and watch and widely recognizes
It can and apply.
The vacuum plating scope of application is wider, the product expected such as ABS material, ABS+PC material, PC.The way of general vacuum plating is
One layer of priming paint is first sprayed on material, then is electroplated.Since material is plastic part, the meeting residual air bubble in injection molding, organic gas,
And the moisture in air can be sucked when placing.In addition, since frosting is not smooth enough, the workpiece surface being directly electroplated is not only
Sliding, gloss is low, and metal sense is poor, and will appear bubble, the undesirable conditions such as bubble.After spraying last layer priming paint, one can be formed
Smooth surface, and the generation for the existing bubble bubble that prevented plastics itself so that the effect of plating is showed.
Polyurethane（PU）Lotion and polyacrylic acid（PA）Lotion has inexpensive, safety compared with its solvent based product, non-ignitable
Burn, it is nontoxic, it is free from environmental pollution the advantages that.Pure PA lotions are single there are wearability, the defect of water resistance and chemical-resistant difference
There is also some shortcomings for PU lotions, and the gloss retention such as stability, white thickening property and film is poor, and solid content is high, and application range is not wide etc..
PU and PA has complementation in nature.The advantages of PUA complex emulsions have had both the two, have it is wear-resisting, corrosion-resistant and bright,
The characteristics such as softness is flexible, and water resistance and mechanical mechanics property are good, and weatherability is good, therefore it is known as " the aqueous poly- ammonia of the third generation
Ester " becomes a development trend of current coating.
Since economic rapid development and China are as global manufacture base, to vacuum plating ultraviolet-curing paint
Demand pressure it is increasing.PUA complex emulsions have wear-resisting, corrosion-resistant and bright, soft flexible, water resistance and mechanical force
Learn the characteristics such as performance is good, and weatherability is good.Using aqueous polyurethane acrylate complex emulsions as raw material, in conjunction with vacuum plating process
One important directions of China's coatings industry Future Development will be become, had broad application prospects.
Invention content
It, can be with the purpose of the present invention is on the basis of existing technology, providing a kind of water-borne UV-curing vacuum plating priming paint
The workpiece surface for solving plating is rough, and gloss is low, and metal sense is poor, the bad problem such as poor adhesive force, not wear-resisting.
Another mesh of the present invention is to provide a kind of preparation method of above-mentioned water-borne UV-curing vacuum plating priming paint.
The present invention also provides a kind of water-borne UV-curing vacuum plating priming paint to carry out electric plating method.
The priming paint of UV vacuum platings is the coating coated in plastic basis material surface, its effect is closing plastic basis material, is prevented
Only volatile materials when vacuum plating in base material influences the quality of plated film.Frosting is rougher, can be obtained by priming paint coating
Smooth mirror effect, be conducive to obtain thicker and uniform vacuum metal coating, show higher metallic luster with
Reflecting effect.For the lower base material of some polarity, by priming paint transition can make the metal coating of vacuum plating obtain compared with
Good adhesion property.The plastic basis material poor to part heat resistance, priming paint also play certain hot cushioning effect.
The priming paint of UV vacuum platings must have to plastic basis material and the good adhesive force of vacuum coating metal layer, that is
Coating should be good with the attachment of low pole plastic rubber substrate well, there is good adhesive attraction with polar metal again, this ratio
Simple plastic coating requires higher.In order to ensure that the high glaze and mirror effect of the coat of metal, priming paint must have very excellent
Different flow leveling.In addition, there should not be volatile small molecule after solidifying priming paint again, the quality and property of the coat of metal otherwise can be destroyed
Energy.
