Abstract
A kind of water colour paint film build method, on metal base, by water colour paint blade coating into wet film, colored paint, which dodges to do to film coated surface, to be dried, and then in water colour paint surface showering varnish from top to bottom, obtains varnish paint film, varnish dodges the final paint film of dry doubling drying.The method of the present invention, knife coating and curtain coating are combined, shortens and prepares the film time, improves the efficiency of film forming, and Fast Evaluation is carried out beneficial to the pin hole foams performance to water colour paint.
Description
Technical field
The present invention relates to a kind of detection method of coating property, more particularly to a kind of water colour paint film build method, to realize
Caused pin hole foams performance in water colour paint application is used for quickly detecting, to shorten the screening cycle of colored paint formulation.
Background technology
In drying process of the water colour paint coating after application, because moisture is not discharged in time, varnish is being sprayed simultaneously
During height baking (baking temperature is more than the boiling point of water), water occurs boiling and produces Pinhole-shaped aperture or showing as leather pore
As being referred to as " pin hole " in industry, being a kind of film defect common in paint spraying and drying process.
Among the construction application process of water colour paint, pin hole bubble is to be easy to multiple application disadvantage, is commented in formula
In estimating and testing, spraying is all relied at present prepare model and reevaluate, that is, spray colored paint, varnish and toasting completely is painted
Film, then observe whether paint film has pin hole bubble.
Influenceed very big by spray plate stability and reappearance, the efficiency comparison of existing coating method is low.If count machine in
Including the time such as device cleaning and stand-by period, a preparation of specimen time needs about 2 hours, is sieved for the formula of water colour paint
It is considerable that the development of choosing experiment (multiple samples need to contrast spraying and assessed) consumes resource.
Therefore, existing paint film preparation method is difficult in adapt to the cycle request of quick screening colored paint formulation.
The content of the invention
It is an object of the present invention to provide a kind of water colour paint film build method, shortens the film time.
It is another object of the present invention to provide a kind of water colour paint film build method, to simulate water colour paint coating process
The pin hole bubble situation of middle generation, and it is applied to water colour paint recipe determination process, the quick pin judged in water colour paint application
Hole foams performance, shorten the screening cycle of colored paint formulation.
A kind of water colour paint film build method provided by the invention, including：
In metal base (such as：Tinplate) on, by water colour paint blade coating into wet film, colored paint, which dodges to do to film coated surface, to be done
It is dry, then in water colour paint surface showering varnish from top to bottom, varnish paint film is obtained, varnish dodges dry doubling drying, obtains final paint
Film.The bubble pin hole of film is observed, and by the coating performance of existing bubble pin hole determination methods evaluation water colour paint.
The method of the present invention, water colour paint is scratched out wet film, uniform film thickness by it using film caster.
There are the varnish paint film of film thickness gradient in the method for the present invention, varnish paint film system.
The method of the present invention, colored paint dodge dry process and are：First room temperature, which is dodged, to be done 5 minutes, is dodged at 60 DEG C~80 DEG C dry 2 minutes
~5 minutes, then cool down at room temperature.
The method of the present invention, varnish dodge dry process and are：Room temperature, which is dodged, to be done 7 minutes, then at 140 DEG C of baking ovens, is baked 20 minutes.
The inventive method, the pin hole foams performance applied to detection water colour paint film.
The beneficial effect that technical solution of the present invention is realized：
Water colour paint film build method provided by the invention, knife coating and curtain coating are combined, and shorten the film time
50%, energy consumption and manpower are significantly reduced, improves the efficiency of water colour paint film forming.
Method provided by the invention, it is suitable for water colour paint recipe determination, is sent out with simulating in water colour paint coating process
Raw pin hole bubble situation, and quickly judge the pin hole foams performance in water colour paint application, shorten the screening week of colored paint formulation
Phase.
Brief description of the drawings
Figure 1A is an embodiment schematic diagram of the inventive method film caster；
Figure 1B is the schematic cross-section of film caster shown in Figure 1A；
Fig. 2 is the embodiment schematic diagram that varnish uses curtain coating in the inventive method.
Embodiment
Technical scheme is described in detail below in conjunction with accompanying drawing.The embodiment of the present invention only to illustrate the present invention skill
Art scheme and it is unrestricted, although the present invention is described in detail with reference to preferred embodiment, one of ordinary skill in the art
It should be appreciated that the technical scheme of invention can be modified or equivalent substitution, without departing from the essence of technical solution of the present invention
God and scope, it all should cover in scope of the presently claimed invention.
Water colour paint carries out film forming to the present embodiment as follows：
First a tinplate top on about 10g water colour paint samples, with film caster (referring to Figure 1A, Figure 1B
And Fig. 2, the cell body shaped like both ends insertion, groove depth H are 100 μm) scratch out colored paint wet film, about 100 μm of thickness；
Then, will prepare the colored paint film elder generation room temperature completed dodge it is dry 5 minutes, dodged at 60 DEG C~80 DEG C it is dry 5 minutes (
Can be obtained with setting time again it is shorter so that condition is harsher), then in room temperature cool down 5 minutes；
Then, referring to Fig. 2, curtain coating is pressed on the water colour paint surface 200 of surface drying, showering varnish 200, is obtained from top to bottom
There is the varnish paint film of film thickness gradient；
Finally, dodge and do 7 minutes at room temperature, then put 140 DEG C of baking ovens into, be baked 20 minutes, produce complete paint film.
The water colour paint film build method that the present embodiment provides, compared with existing conventional film build method, disappears from the overall time
Consumption is significantly reduced, and the energy consumption cost of spraying process (spraying robot, the spraying energy and spraying manpower) significantly reduces, film forming effect
Rate is improved, and is alleviated the production capacity bottleneck of paint application link, is referred to table 1.
Table 1
The bubble pin hole of film is observed, and by the coating performance of existing bubble pin hole determination methods evaluation water colour paint.
