Description
Technical field
The present invention relates to polymeric material field, and in particular to a kind of ultraviolet light cure solvent-free coated matte finishing coat and its
Preparation method.
Background technology
UV paints are the english abbreviations of Ultraviolet Curing Paint, i.e. ultraviolet-curing paint, its principle of solidification
It is coating under ultraviolet light, photoinitiator absorbs ultraviolet light and then decomposition, generates free radicals and light-cured resin and work
Property diluent crosslinks, in moment, that is, curable film-forming.There is environmental protection, efficient, low cost.Spraying is photo-curing paint
A kind of conventional construction technology, conventional ultraviolet light cure coated matte finishing coat need add 30%-50% organic solvent it is dilute
Construction is released, since VOC volatilizees so that the coating of original environmental protection loses an advantage of maximum.How to solve the problems, such as this, subtract
It is small extremely urgent to large natural environment pollution.
The content of the invention
, also can be normal in the case of organic solvent-free it is an object of the present invention to provide a kind of UV-curable finish coat
Construct and obtain preferable lacquer painting effect.
Technical solution provided by the invention is as follows：
A kind of ultraviolet light cures solvent-free coated matte finishing coat, including following weight percent composition：
Nine functional group ultra-branched polyurethane acrylate resin 5%-25%,
Modified epoxy acrylic ester resin 5%-20%,
Auxiliary agent 10.8%-26%,
Photoinitiator 3%-6%,
UV reactive diluents 30%-60%.The UR2044 of the preferred blue card of the nine functional groups ultra-branched polyurethane acrylate resin;
The 6210G in described preferred Changxing of modified epoxy acrylic ester resin.
Further, it is described account for percentage by weight 10.8%-26% auxiliary agent be：
Dispersant 0.3%-3%,
Defoamer 0.1%-0.5%,
Flatting silica 10%-20%,
Polyethylene wax powder 0.1%-1%,
Levelling agent A0.2%-1%,
Levelling agent B0.1%-0.5%.The Luwax A of the preferably German BASF of the Tissuemat E or the 3620 of Clariant.
Further, the dispersant is for the high-molecular block copolymer of the affinity groups containing pigment or containing acidic-group
Copolymer solution.It is preferred that BYK-163, BYK-110, BYK-2009 etc..
Further, the defoamer is modified polyorganosiloxane defoamer.The modified polyorganosiloxane defoamer is excellent
Select 5300 or 5400 or BYK-141 that moral is modest etc..
Further, the flatting silica is aerosil flatting silica.The preferred Gray of aerosil flatting silica
This RAD2105, the flatting silica oil absorption are 120g/100m, are much smaller than most of flatting silica, such as Degussa
OK500 oil absorptions are 260g/100m；Therefore viscosity increase to system is minimum, is conducive to be not added with organic solvent directly to spray
Apply construction.
Further, the levelling agent A is fluorine-carbon modified polyacrylate high polymer.It is preferred that BYK358N, excellent card
376S。
Further, the levelling agent B is the polyether-modified dimethyl silicone polymer of finger.It is preferred that TEGO245, BYK333.
Further, the photoinitiator for 2- hydroxyls -4 ' -（2- hydroxy ethoxies）- 2- methyl phenyl ketones.It is preferred that Bath
The 2959 of husband.
Further, the UV reactive diluents for tripropylene glycol diacrylate, two contracting propane diols double methacrylates,
One or both of hydroxyethyl methacrylate.It is preferred that the HEMA in Changxing, DPGDA, TPGDA etc..
A kind of ultraviolet light cures the preparation method of solvent-free coated matte finishing coat, includes the following steps：
Step A. first puts into resin and UV reactive diluents, dispersant to reaction kettle in formula, with 1000-1200 rpms
Rotating speed disperses 20-30 minutes；
Step B. is disperseed 20-30 minutes according to formula input defoamer, levelling agent with 800-1200 rpms of rotating speed；
Step C. puts into photoinitiator, is disperseed 20-30 minutes with 1000-1200 rpms of rotating speed；
Step D. disperses 30-40 points according to formula input flatting silica and polyethylene wax powder with 1200-1800 rpms of rotating speed
Clock；
Step E. puts into all remaining UV reactive diluents, is disperseed 15-20 minutes with 600-800 rpms of rotating speed, after
Filtered and packaged with 300 mesh filter screens.
Compared with prior art, innovative point of the invention is：
Introduce nine functional group's super branched polyurethanes and high reaction rate is provided, it is with extremely low viscosity（600-1200mpa•s）,
So that in the case where curing rate is exceedingly fast, it can not construct without because of the excessive viscosity of resin, avoid organic volatile
The generation of thing.Also arrange in pairs or groups modified epoxy acrylic ester resin, while low viscosity is kept, gloss protrudes after curing, has reason
The appearance thought, hardness, wear-resisting property, weatherability, chemical-resistant, resistance tocrocking etc. is good.
UV reactive diluents select low-shrinkage, monomer HEMA, DPGDA of highly diluted, so as to reduce the receipts of system
Shrinkage, greatly reduces the viscosity of spraying paint, makes the solvent-free spraying paint more convenient in construction.
