Description
Technical field
The invention belongs to technical field of coatings, and in particular to a kind of water-based UV of Diamond Search (ultraviolet light) cured varnish and its system
Preparation Method and application.
Background technology
UV is coating material solidified in publicity, and it is mainly characterized in that without solvent, clean and effective, 100% film-forming, paint film
Energy is excellent, can effectively reduce organic volatile (VOC) discharge etc., therefore extremely wide application has been obtained in recent decades；But
It is actually traditional UV coating material solidified not entirely without noxious pollutant and Diamond Search.It is coating material solidified mainly due to traditional UV
Use the prepolymer of low molecule amount, viscosity is higher, it is necessary to add and adjusted containing a large amount of small molecule response type reactive diluents
System viscosity and rheological characteristic, improve the performance of cured film., can be right and these reactive diluents largely have toxicity and excitant
Environment and health cause necessarily to damage.

Part, 0.2~0.4 part of levelling agent, 0.2~1.5 part of thickener, 0~2 part of cosolvent.The addition of the coalescents can enter one
Step improves the filming performance and paint film self performance of paint film.
The defoamer is selected from organosiloxane class defoamer, the hydrophobic solid without organosilicon and brokenly bubble polymer
Mix one kind in species defoamer；Present invention preferably employs the BYK024 of German BYK companies, German Di Gao companies
TEGO810 type products.
The wetting agent is organosilicon moistening flatting agent；The wetting agent has a variety of work(such as reduction surface tension, wetting
Can, dynamic moisture ability of the system to various base materials can be improved, reduces surface tension strongly；Present invention preferably employs Bi Ke chemistry
BYK349 type products.
The levelling agent is polysiloxane-based levelling agent；The levelling agent can effectively reduce body surface tension force, promote stream
It is flat, while there is improvement transparency, slipping, anti-shrinkage cavity effect.Present invention preferably employs the high company's T EGO450 models of German enlightening
Product.
The one kind of the thickener in polyethers thickener, polyether-modified polyurethanes thickener；Polyethers of the present invention
Class thickener is preferably using the modest R299 type products of the RM-2050D type products or Shanghai moral of ROHM AND HAAS.The cosolvent
For TPNB.
The present invention especially with the addition of cosolvent and two kinds of defoamers, have its described water-based UV varnish preferably penetrating
Property and gloss.As the preferred scheme of the present invention, the water-based UV varnish, by weight, including following component：70~90 parts
