Description
Technical field
The invention belongs to paint fields, and in particular to a kind of electrostatic spraying UV finishing coat and preparation method thereof.
Background technique
Timber electrostatic spraying light UV is in industry still in blank, and technological difficulties are that UV light effect difficulty is done, timber
The problem of area is big, and integral spray will coordinate the light effect and performance of paint, usually, the film of facade spraying will not
It is too thick, therefore, high plentiful effect how is realized under conditions of relatively thin spray, is technological difficulties one；Reach high plentiful effect
Under the premise of, film can not be too thick, because being vertical spray, it is easy to and how sagging accomplishes facade spraying not sagging, this
It is technological difficulties two.
Summary of the invention
In view of the problems of the existing technology, one of the objects of the present invention is to provide a kind of electrostatic spraying UV finishing coats.This
The another object of invention is to provide the preparation method of electrostatic spraying UV finishing coat.
Electrostatic spraying UV finishing coat of the invention, is achieved through the following technical solutions:
A kind of electrostatic spraying UV finishing coat, according to parts by weight, including following raw material components:
Preferably, the electrostatic spraying UV finishing coat, according to parts by weight, including following raw material components:
Preferably, the electrostatic spraying UV finishing coat, according to parts by weight, including following raw material components:
Further, the epoxy resin is Changxing epoxy 621A-80.
Further, the dispersing agent is Bi Ke chemistry BYK103 dispersing agent；The defoaming agent is Ai Fukena
EFKA2072；The levelling agent is Bi Ke chemistry BYK300.
Further, the modified polyester acrylate ester resin is 2316 model resins of double bond chemistry, admittedly contain 100%.
Further, the monomer is NPGDA, which is the acrylic ester monomer that three wooden chemistries provide, molecular weight
212。
Further, the photoinitiator is 184 (1- hydroxycyclohexyl phenylketone, λ of 1-2 parts of BASF chemistrymax?
246nm, 280nm, 333nm), TPO (the 2,4,6- trimethylbenzoyl madder ethoxyl phenenyl oxidations of 0.5-1 parts of BASF chemistry
Phosphine), 1173 (2- hydroxy-2-methyl -1- phenylacetone, λ of 3-5 parts of double bond chemistrymaxIn 245nm, 280nm, 331nm).
Further, the A81 of the aldehyde ketone resin model BASF chemistry, solid content 70%.The aldehyde ketone resin can mention
While high coating film gloss and richness, play the role of resist sagging, using general UV resin cannot play improve gloss and
The effect of anti-sag, aldehyde ketone resin are originally the materials for PU system, as the effect for improving richness, but since itself belongs to
Self-drying type resin, is not involved in the photocuring reaction of UV, therefore typically no in UV system, partially slow if processing is bad
Dry characteristic will affect the performance of UV paint.
Further, the solvent is ethyl ester.
A kind of preparation method of electrostatic spraying UV finishing coat, comprising the following steps: by epoxy resin, modified polyester acrylate ester
Resin, dispersing agent, defoaming agent, levelling agent mixing, are dispersed 5-30 minutes using dispersion machine 500-800rpm, add monomer, light
Initiator, 1000-1500rpm disperse 10-30 minutes, add solvent, aldehyde ketone resin, and 500-800rpm disperses 5-15 minutes,
Up to the electrostatic spraying UV finishing coat.
When product of the present invention (UV sprays light top coat top coat) construction, is sprayed using electrostatic reciprocating engine facade, be directly connected to spraying machine
The gear pump of machine is pumped into paint into paint finishing and sprays, which is electrostatic spraying, and electrostatic spraying utilization rate reaches
80%, and general hand spray or the utilization rate of plane machine reciprocating engine spraying only have 30%；Since the equipment is facade spraying,
Therefore coating weight must spray low than plane, and the coating weight of plane spraying is 300g/ squares (containing loss)；And electrostatic spraying
Coating weight is 130g/ squares (containing loss), therefore by the cooperation of equipment, the UV spray light top coat top coat with oil at instinct substantially
Decline, through calculating, former PU product is 8.4 yuan/square with oily cost, and the UV electrostatic spraying light top coat top coat is with oily cost
6.5 yuan/square, it is lower with oily cost, and bring maximum value to be Furniture Factory, the yield bottleneck of PU is originally used daily
300 sets/day, 800 sets/day can be promoted to by the transformation of UV, yield promotes 265%.
Compared with the existing technology, beneficial effects of the present invention:
(1) UV finishing coat of the invention has good light effect under conditions of thin spray and filling is plentiful；
(2) UV finishing coat facade of the invention sprays not sagging.
