The present invention relates to a kind of machine method for paint spraying, comprise the following steps：(1) prime；(2) first layer finish paint is applied, sprays second layer finish paint again after first layer finish paint is dried；(3) transparent painting：At least layer of transparent paint is sprayed on the surface of the second layer finish paint；The first layer finish paint is dried by the way of drying, and the temperature of the drying is 100 200 degrees Celsius, the workpiece temperature by drying also makes the second layer finish paint be more prone to adhere to simultaneously, the second layer finish paint is dried by the way of drying, at room temperature, dry 10 15 hours.The advantage of the invention is that：The method of drying is employed in the drying of first layer finish paint, therefore accelerates the volatilization of solvent, so as to successfully avoiding pit, turning white and flowing the defects of painting, floating coat is by the way of spontaneously drying, fixation.
Description
Technical field
The present invention relates to a kind of field of machining, more particularly to a kind of machine method for paint spraying.
Background technology
Generally spray painting use method be：Pass through spray-applied primer, first of finish paint, second finish paint, the colored varnish successively, its
In first of finish paint take is surface drying, i.e., dried in the environment of 70 DEG C or so.However, the painting environment during spray painting
Problem, because environment is unholiness, many dusts are mingled with wherein, thus form pit after causing spray painting, it is generally the case that due to
The defects of pit, causes to paint qualification rate less than 10%, how to prevent from occurring in painting process pit be this area directly facing
One technical problem.Caused by being really fine dust attachment due to pit, therefore to eliminate pit needs and increase substantially spray
Clean environment degree is painted, but this can make spray painting cost be enhanced several times.
In addition, the reason for the defects of causing the pit not be it is unique, in addition to dirt, it is also possible to cross spray or
The other reason of person, such as the reason such as levelling is insufficient, drying temperature is too high, coating quality；It is also important to spray the selection of tool, matter
The flow that bad spray has uncontrollable good spray gun rifle mouth is measured, the problems such as so as to also result in pit；In addition, the enamelled coating mistake of spraying
It is thick and be unfavorable for the exclusion of bubble, it is also possible to cause pit.
Paint in addition to it there can be the defects of pit, also white point problem, if the defects of overspray can also flow paint.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of machine method for paint spraying.
In order to solve the above technical problems, the technical scheme is that：A kind of machine method for paint spraying, its innovative point are：
The first layer finish paint is dried by the way of drying, and the temperature of the drying is 100-200 degrees Celsius, is passed through simultaneously
The workpiece temperature of drying also makes the second layer finish paint be more prone to adhere to, and the second layer finish paint is carried out by the way of drying
Dry, at room temperature, dry 10-15 hours.
Further, also include the step of derusting before the step (1), the derusting using chemicals cleaning or
Pneumatic draw point pistol for rust removal derusts.
Further, also include the step of derusting before the step (1), the derusting using chemicals cleaning or
Pneumatic draw point pistol for rust removal derusts.
The advantage of the invention is that：The method of drying is employed in the drying of first layer finish paint, therefore accelerates solvent
Volatilization, so as to successfully avoid pit, turn white and flow paint the defects of, floating coat using natural drying by the way of, fix tightly
Gu.
Embodiment
The invention discloses a kind of machine method for paint spraying, comprise the following steps：
1) derust：If workpiece surface has iron mold, manual removal is carried out with scraper, emery cloth and steel brush class instrument, if necessary
Chemicals (such as pickling, it is formulated as sulfuric acid, peregal, hexamethylenetetramine, water) cleaning can be used, in addition, also can use gas
Dynamic draw point pistol for rust removal.Preferably, using preferably selecting office's moat type pipette tips during the rifle.The paint if workpiece surface is had been friends in the past, carries out depainting：
Being whole depaintings or local depainting is determined during operation according to the situation of piece surface.Preferably, depainting using sandblasting depainting,
The method of paint stripper depainting.After old paint film is removed totally, piece surface is cleaned up with warm water.And will with gasoline or kerosene
Remaining paint stripper is cleaned, in order to avoid influence the gloss of new lacquer painting, drying and adhesive force.With adhesive plaster, paper or lubricating grease etc. to not
The position for needing to spray block being protected by；
2) prime；The defects of Puttying is filled out to eliminate the pit of piece surface, stomata, pitted skin, scratch, makes its uniform ground.
If when piece surface depression too depth or excessive area, it can be rapped with rubber hammer at this, it is full of reinstatement, the first level
Paint is dried by the way of drying, and the temperature of the drying is 100-200 degrees Celsius；
3) polish：Polishing can use dry grinding or water mill, no matter using which kind of, after polish by floating dust, incrustation scale remove totally, and
It is completely dried surface stand-by；
4) base coat is applied：Putty after polishing can not possibly all be smooth, it sometimes appear that many hole sizes
Sand holes, if do not repaired, bubble is formed in situ, influences the total quality and outward appearance of finish paint.So second at this moment must be applied
Road priming paint, and be dried by the way of drying, at room temperature, dry 10-15 hours, it is therefore an objective to fill up pin hole sand holes, together
When be also for later process finish paint increase adhesion；
5) paint：Through look into piece surface really without sand holes after can be with spray paint.Finish paint first uses the thin spray of spray gun when spraying
One layer, spray the second layer, third layer again after parching, can not be acted with undue haste when desired light tone, spraying, once spray and hold very much
Easily spray is thick, causes uneven shade, or water droplet phenomenon.Preferably, first layer finish paint is dried by the way of drying, it is excellent
Selection of land, the temperature of the drying is 150 DEG C or so, due to workpiece, such as wheel hub, can be accelerated in first layer finish paint by drying
Solvent volatilization, so as to avoid pit phenomenon, while the wheel hub temperature by drying is also more prone to second layer finish paint
Attachment, avoid turning white and flow paint phenomenon；
6) transparent painting：One layer or several layers of colored varnishes, i.e. varnish are sprayed on finish paint surface, to improve surface quality；
7) polish：For further smooth coating surface, it is allowed to bright attractive in appearance.Due in the method for paint spraying in the present invention first
The method of drying is employed during the drying of aspect paint, therefore accelerates the volatilization of solvent, so as to successfully avoid pit, turn white
The defects of being painted with stream.
The general principle and principal character of the present invention has been shown and described above.It should be understood by those skilled in the art that
The present invention is not limited to the above embodiments, merely illustrating the principles of the invention described in above-described embodiment and specification,
Without departing from the spirit and scope, various changes and modifications of the present invention are possible, and these changes and improvements all fall
Enter in scope of the claimed invention.The scope of the present invention is defined by the appended claims and its equivalents.
