A kind of paint coating process of UV priming paint and aqueous face
Technical field
The present invention relates to water paint spraying technology field, the paint coating process of specifically a kind of UV priming paint and aqueous face.
Background technique
It is all with water as solvent or to make the coating of decentralized medium, it all can be described as water paint.Water paint includes water-soluble, water
Dilution type, 3 kinds of water-dispersion type (emulsion paint).
It is novel contaminated product water paint application technology that UV, which adds at bottom color contaminated product aqueous finish paint coating process, is mainly used in house
Tool, door, window, wallboard etc., contaminated product product in the market generally have three kinds of the bottom the PU face PU, the bottom the NC face NC and PU bottom water face, use
Mostly oiliness Polyester Paint, environmental-protecting performance is poor, poor safety performance, and later period benzene and voc release are all very high, not only pollutes ring in this way
Border, and be absolutely unsafe, complex process long construction period inefficiency;Although it is mixed also to begin to use the bottom UV to add color now
Its effect of oily aqueous finish paint, is reduced environmental pollution by water paint, reduces human injury, but existing water paint sprays work
Skill is complicated, and the spraying application period is long, low efficiency.
Summary of the invention
The purpose of the present invention is to provide the paint coating process of a kind of UV priming paint and aqueous face, to solve above-mentioned background technique
The problem of middle proposition.
To achieve the above object, the invention provides the following technical scheme:
A kind of paint coating process of UV priming paint and aqueous face, comprising the following steps:
Step 1, the coating of first time UV priming paint, roller coating amount is 25g/ ㎡ -35g/ ㎡, is dried after coating, is passed through when dry
Ultraviolet light solidifies UV priming paint;
Step 2 carries out first time sanding to the UV priming paint after drying;
Step 3 carries out second of UV priming paint coating to the lacquer painting after first time sanding, and quantity for spray is 110 g/ ㎡ -130g/ ㎡,
UV priming paint is solidified by ultraviolet light after spraying;
Step 4 carries out secondary sanding to the lacquer painting of the UV priming paint after secondary coating;
Step 5 sprays aqueous finish paint to the UV priming paint lacquer painting after sanding, and quantity for spray is 120g/ ㎡ -140g/ ㎡;
Step 6 carries out levelling in the environment of 20 DEG C -30 DEG C of constant temperature, humidity 40%-55%;
Step 8 is dried in the environment of 50 DEG C -60 DEG C of constant temperature, humidity 30%-50%;
Step 9 is dried under normal temperature environment.
As a further solution of the present invention: first carrying out putty roller coating and super white before the coating of UV priming paint in the step 1
Bottom roller applies, and the putty roller coating amount is 20g/ ㎡ -40g/ ㎡, carries out half-dried processing after roller coating;The roller coating amount of super white background is
30g/ ㎡ -40g/ ㎡, carries out half-dried processing after coating;Absolutely dry processing is carried out after the coating of UV priming paint.
As a further solution of the present invention: the roller coating amount of the putty is 30g/ ㎡, the roller coating amount of the super white background
For 35g/ ㎡, the coated weight at the bottom UV is 30g/ ㎡.
As a further solution of the present invention: coating method in the step 1 is soft roller roller coating, in the step 3
Coating method is reciprocating engine covering spraying, and the coating method in the step 5 is spraying method.
As a further solution of the present invention: sanding first carries out sanding using piano type sander in the step 2 makes again
Sanding is carried out with Heterotype sander, the key sander uses 320#-400# emery stick, and the Heterotype sander uses 240#-
320# emery stick.
As a further solution of the present invention: second of UV basecoat paint use solvent-free UV priming paint, described second
The quantity for spray of secondary UV priming paint is 120g/ ㎡.
As a further solution of the present invention: secondary sanding first uses Heterotype sander to carry out sanding again in the step 4
Sanding is carried out using piano type sander, the Heterotype sander uses 320#-400# emery stick, and the piano type sander uses
400#-600# emery stick.
As a further solution of the present invention: carrying out removing surface after the secondary sanding, pass through the sand paper of 400#-600#
To after secondary sanding plane and corner clear up.
As a further solution of the present invention: aqueous finish paint is single color contaminated product aqueous finish paint or more face in the step 5
Color contamination oil aqueous finish paint, the quantity for spray of the water paint are 130g/ ㎡.
As a further solution of the present invention: the flash-off time in the step 9 is 12 hours.
Compared with prior art, the beneficial effects of the present invention are:
1, the application carries out UV light after UV basecoat paint and dries processing, can reach at immediately dry instant sanding
Reason, thus the drying time of priming paint is greatly reduced, the production time is thereby reduced, production efficiency is improved;
2, the application uses single-component water-based paint, in equipment spraying, can carry out recycling and reusing to extra water paint, because
And the usage amount of whole water-based paint is reduced, reduce production cost.
