Abstract
The invention relates to a painting method. The painting method comprises the following steps of: (1) painting a primer; (2) painting a first layer of finish paint and then painting a second layer of finish paint after the first layer of finish paint is dried; and (3) painting celluloid paint, namely painting at least one layer of celluloid paint on the surface of the second layer of finish paint. The painting method is characterized in that: the first layer of finish paint is dried in a baking mode and the drying temperature is between 140 and 160 DEG C, so that the volatilization of a solvent in the first layer of finish paint is accelerated and a pockmark phenomenon can be avoided; and at the same time, the second layer of finish paint is more susceptible to adhesion by the temperature of a dried workpiece, so that whitening and paint-flowing phenomena can be avoided. In the painting method, the first layer of finish paint is dried by a drying method, so the volatilization of the solvent is accelerated and the pockmark, whitening and paint-flowing defects are overcome successfully.
Description
Technical field
The present invention relates to a kind of method for paint spraying, particularly relate to a kind of method for paint spraying that is used for wheel hub.
Background technology
Spray paint and plastic-blasting is the main path that current industrial surface is decorated, spray paint compare with plastic-blasting have levelling good, can repair, pliability good, ornamental abundant, hardness is high, efficient is high, overcome the advantage of ground defective easily, thereby has obtained application more and more widely.Usually the method that adopts of spraying paint is: through spraying priming paint, the first road finish paint, the second road finish paint, the colored varnish, what wherein the first road finish paint was taked is surface drying successively, and promptly the environment about 70 ℃ is dry down.
Yet, the problem of environment of in the process of spraying paint, spraying paint, because environment is unholiness, many dusts are mingled with wherein, thereby the back that can cause spraying paint forms pit, generally, because the defective of pit causes the qualification rate of spraying paint less than 10%, how preventing to occur in the painting process pit is the technical problem that this area is directly faced.Because pit is actual is that fine dust is adhered to and caused, and therefore will eliminate pit need increase substantially the clean environment degree that sprays paint, but this can make the cost that sprays paint be enhanced several times.
In addition, the reason that causes the defective of described pit is not to be unique, except dust, may be spray or other reason yet,, reasons such as bake out temperature too high, coating quality insufficient such as levelling; The selection of spray tool is also important, the flow of the uncontrollable good spray gun rifle mouth of poor quality's spray tool, thus also can cause problem such as pit; In addition, the enamelled coating of spraying is blocked up and be unfavorable for the eliminating of bubble, also might cause pit.
Spray paint except there is the defective of pit in meeting, also have the white point problem, if overspray also can flow the defective of lacquer.
Summary of the invention
The purpose of this invention is to provide a kind of can prevent to occur in the painting process pit and/or stream lacquer and/or white-spot defects, simple to operate, method for paint spraying that cost is low.
For solving the problems of the technologies described above, the present invention takes following technical scheme: a kind of method for paint spraying may further comprise the steps: prime (1); (2) be coated with the ground floor finish paint, will spray second layer finish paint again after the ground floor finish paint drying; (3) transparent painting: on the surface of described second layer finish paint, spray layer of transparent lacquer at least; It is characterized in that: described ground floor finish paint adopts the mode of oven dry to carry out drying, and the temperature of described oven dry is 140-160 degree centigrade, to quicken the solvent evaporates in the described ground floor finish paint, thereby can avoid the pit phenomenon, workpiece temperature through oven dry also makes described second layer finish paint be more prone to adhere to simultaneously, thereby avoids turning white and flowing the phenomenon of coating with lacquer.
Owing to when ground floor finish paint dry, adopted the method for oven dry in the method for paint spraying among the present invention, therefore quickened the volatilization of solvent, thereby successfully avoided pit, turn white and flow the defective of coating with lacquer.
The specific embodiment
Below technical scheme of the present invention is elaborated.
Method for paint spraying among the present invention may further comprise the steps:
(1) rust cleaning: if surface of the work has iron mold, then carry out manual removal, also can adopt chemicals (as pickling, its prescription is sulfuric acid, peregal, hexamethylenetetramine, water) to clean in case of necessity with scraper, emery cloth and steel brush class instrument, in addition, also available pneumatic draw point pistol for rust removal.Preferably select an innings moat type rifle head when preferably, using this rifle for use.
(2) lacquer if surface of the work is had been friends in the past then carries out depainting: will determine that whole depaintings still are local depainting according to the situation of piece surface during operation.Preferably, depainting adopts the method for sandblast depainting, paint stripper depainting.Old paint film will clean up piece surface with warm water after removing totally.And with gasoline or kerosene that the paint stripper of remnants is clean, in order to avoid influence gloss, drying and the adhesive force of new lacquer painting.
(3) with adhesive plaster, paper or lubricating grease etc. the position that does not need to spray is blocked and protected.
(4) prime.
(5) fill out Puttying with defectives such as the pit of eliminating piece surface, pore, pitted skin, scratches, make it evenly smooth.If piece surface depression is too dark or area when excessive, available rubber hammer raps this place, makes it be full of reinstatement.
(6) polishing: polishing can be adopted dry grinding or water mill, and which kind of no matter adopts, and floating dust, incrustation scale will be removed totally, and is made surperficial bone dry stand-by after having polished.
(7) be coated with base coat: through the putty after the polishing can not all be smooth smooth, occurs the sand holes of many hole sizes sometimes, if do not repaired, forms bubble on the spot, influences the total quality and the outward appearance of finish paint.So at this moment must be coated with the second road priming paint, purpose is to fill up the pin hole sand holes, also is simultaneously the finish paint increase adhesion for later process.
(8) be coated with finish paint: just can spray paint after looking into piece surface not have sand holes really.Finish paint when spraying be earlier with the thin spray of spray gun one deck, sprays the second layer, the 3rd layer after waiting to parch again, up to the light tone that requires, can not act with undue haste during spraying, and once spraying is easy to spray thick, causes color and luster irregular, or the water droplet phenomenon.
Preferably, the mode that the employing of ground floor finish paint is dried is carried out drying, preferably, the temperature of described oven dry is about 150 ℃, because workpiece, for example wheel hub, through drying the solvent evaporates that to quicken in the ground floor finish paint, thereby can avoid the pit phenomenon, the wheel hub temperature through oven dry also makes second layer finish paint be more prone to adhere to simultaneously, avoids turning white and flowing the phenomenon of coating with lacquer.
(9) transparent painting: spraying one deck or which floor colored varnish on the finish paint surface, i.e. varnish is to improve surface quality.
(10) polishing: be used for further smooth coating surface, it is attractive in appearance to make it light.
Owing to when ground floor finish paint dry, adopted the method for oven dry in the method for paint spraying among the present invention, therefore quickened the volatilization of solvent, thereby successfully avoided pit, turn white and flow the defective of coating with lacquer.
