1-2 parts；
(3) preparation of water soluble acrylic acid dispersion: water-based acrylic resin be added under the conditions of 80-90 DEG C neutralizer carry out in and
Reaction is cooled to 60-70 DEG C, and deionized water is added and carries out dispersing to be made water soluble acrylic acid dispersion, based on parts by weight, aqueous
35-45 parts of acrylic resin, 55-65 parts of deionized water.
It can further improve the comprehensive performance of compound resin system using water soluble acrylic acid dispersion provided by the invention.
Further, solvent described in step (1) is selected from butyl acetate；Initiator described in step (2) is selected from persulfuric acid
Ammonium, sodium peroxydisulfate, potassium peroxydisulfate.
Further, the cosolvent is selected from one or both of dipropylene glycol methyl ether or dipropylene.
Further, the photoinitiator is selected from alpha-alcohol ketone, benzophenone, 2- hydroxy-2-methyl -1- phenyl -1- acetone
One of or it is a variety of.
Further, the wetting aid is selected from dodecyne glycol polyoxyethylene ether.
Dodecyne glycol polyoxyethylene ether have extremely low dynamic surface tension and static surface tension (1b/s is static,
6b/s dynamic), paint film can be made to soak substrate rapidly, go deep into wood grain wood hole.
Further, the defoaming agent be selected from acetylenic glycols surfactant, alkyl diol one of surfactant or
Two kinds.
Wetting aid dodecyne glycol polyoxyethylene ether in formula is super wetting aid, with defoaming agent acetylenic glycols table
The surfactant of face activating agent and alkyl diol is arranged in pairs or groups use jointly, reaches wetting wood after paint film can be made to spray in 5~15s
Line, the wooden hole, bubble-free good result, one of prebake process can be quickly entered down.
Further, the auxiliary rheological agents are selected from modified urea solution.
In conclusion the invention has the following advantages:
The first, in UV-curable waterborne woodenware priming paint provided by the invention using waterborne ultraviolet curing resin and it is aqueous from
Crosslinked resin, the two collocation are main film forming substance, enhance the adhesive force and closure of UV-curable waterborne woodenware priming paint.
The second, both water-based aliphaic polyurethane dispersion and water soluble acrylic acid dispersion combination can be made comprehensive
The excellent compound resin system of energy.
Third significantly improves UV-curable waterborne woodenware priming paint using water soluble acrylic acid provided by the invention dispersion physical efficiency
There is very strong practicability there are also the anti-effect for spitting oil to the adhesive force and closure of substrate, while for the timber of oiliness weight.
