Abstract
A kind of engine cylinder-body coating process, carries out cleaning treatment to engine cylinder-body surface first, then spray-applied primer, finish paint；Low-level oxidation treatment is carried out after having sprayed finish paint；Low-level oxidation sprays one layer and is sufficiently mixed uniform mixture by finish paint and coating varnish again after having processed, the finish paint in the mixture can eliminate before step spraying finish paint surface defect；Spraying is dried after finishing.It can form quality coating higher on engine cylinder-body surface, and the antioxygenic property that can improve coating is processed by doing low-level oxidation to finish paint；By spray paint, the mixture of coating varnish, the effective covering to finish paint surface defect is realized, and do not influence the effect of top coat layer script.The first-time qualification rate of spraying is greatly improved, so as to effectively reduce painting cost.The technique also has the characteristics of method is simple, operation is easy, with low cost.
Description
Technical field
The present invention relates to field of coating, and in particular to a kind of engine cylinder-body coating process.
Background technology
Reduce painting cost, improve the theme that coating quality is always application techniques development.Given birth in current pipeline system
In product, once offline qualification rate is always to perplex the major issue of manufacturing enterprise for application.In finishing line construction, spray
After finish paint, the hole eye that exists on finish paint surface, bubble, the flaws such as trace are swept, and the inoxidizability of topcoat is inadequate.Again by spray
Coating varnish is applied, after baking is offline, because the flaw that painting defect is finish paint surface is present under the clearcoat layer of surface, it is impossible to logical
Cross polishing etc. and reprocess means elimination defect, do not reach surface quality requirements and need to do over again again so that production efficiency is substantially reduced,
Production cost increases.This under the fierce overall situation of current industry competition, the high-efficiency and low-cost requirement phase pursued with industry
Instead.Therefore, the qualification rate of application product how is improved, is reduced because reprocessing the loss caused by doing over again, reduces cost, as each as far as possible
The direction that enterprise is continually striving to.
The content of the invention
For the shortcoming for overcoming above-mentioned prior art to exist, it is an object of the invention to provide a kind of coating process, it is big
The big first-time qualification rate for improving application, so as to effectively reduce painting cost.
The technical scheme is that：The engine cylinder-body coating process, comprises the following steps：
Step one, cleaning treatment is carried out to engine cylinder-body surface first, remove the moisture and foreign matter on engine cylinder-body surface, then
Ungrease treatment is carried out to engine cylinder-body；
Step 2 and then in engine cylinder-body surface spraying priming paint, the thickness of priming paint is maintained in 20-50 micrometer ranges；
Step 3, sprayed priming paint after, then spray the finish paint for needing to use, the finish paint thickness is in 110-150 micrometer ranges；
Step 4, sprayed finish paint after, to the treatment of the finish paint low-level oxidation of step 3, the low-level oxidation is processed as anodized；
Step 5, one layer being sprayed again uniform mixture being sufficiently mixed by finish paint and coating varnish, mixing finish paint used is step
Finish paint used in rapid three；The ratio of the mixture is finish paint：Coating varnish=1.5-3: 8.5-7；The mixing of the ratio
The defect on the finish paint surface that can be sprayed with removal process three in thing, nor affects on the effect of clearcoat layer script；
Step 6, spraying are dried after finishing.
As further technical scheme of the invention：
The coating process, the system of the finish paint in the mixture, coating varnish in step 5 is identical.
The coating process, after having sprayed mixture, according to the requirement to coating surface brightness, can again spray one layer of Lacquer finish clear
Paint, then dries again.
The beneficial effects of the invention are as follows：It can form quality coating higher on engine cylinder-body surface, by opposite
Paint does low-level oxidation treatment and can improve the antioxygenic property of coating；By spray paint, the mixture of coating varnish, opposite is realized
Effective covering of surface defect is painted, and does not influence the effect of top coat layer script.The first-time qualification rate of spraying is greatly improved, so as to have
Effect reduces painting cost.The technique also has the characteristics of method is simple, operation is easy, with low cost.
Brief description of the drawings
The present invention will be further described with reference to the accompanying drawings and examples：
Fig. 1 is process flow diagram of the invention.
Specific embodiment
As shown in figure 1, the engine cylinder-body coating process is comprised the following steps：
Step one, the cylinder surface first to needing spray painting are cleaned, and remove dust, particle and moisture of cylinder surface etc.,
Ungrease treatment is carried out to cylinder body again.Cylinder surface first can be wiped with sticky cloth during operation, then blow workpiece surface with electrostatic precipitation rifle,
Electrostatic precipitation is carried out, engine cylinder-body surface is fully finally soaked into phosphatization night degreasing.
Step 2 and then spray-applied primer is carried out in workpiece surface, base coat thickness is in 20-90 micrometer ranges；It is right to strengthen
The protective effect of cylinder body, and one layer of adhesion layer is set up in cylinder surface, the adhesive force of cylinder surface is improved, it is follow-up spraying
Finish paint is prepared, and the fine defects of workpiece surface are also covered in addition, makes workpiece surface more smooth, can be obtained more preferable surface and be applied
Layer, it is ensured that finish paint has sprayed the uniformity of rear coating color.
Step 3, sprayed priming paint after, then spray the finish paint for needing to use, finish paint thickness is in 110-150 micrometer ranges；
The finish paint is a kind of real color finish paint.
Step 4, sprayed finish paint after, to the treatment of the finish paint low-level oxidation of step 3, the low-level oxidation is processed as at anodic oxidation
Reason；The inoxidizability of finish paint can be strengthened, make cylinder body ageing-resistant.
After step 5, low-level oxidation treatment, in spraying, one layer is sufficiently mixed uniform mixture by finish paint and coating varnish, mixes
The finish paint of compound is finish paint of the same race with finish paint used in step 3, and the ratio of mixture is finish paint：Coating varnish=1.5-3:
8.5-7；The defect on the finish paint surface that can be sprayed with removal process three in the mixture of the ratio, nor affects on clearcoat layer
The effect of script.
Finish paint in the mixture, coating varnish ratio is according to job requirement and needs voluntarily to adjust, the face in mixture
The matrix of paint, the system of coating varnish are identical.Spray the mixture to lacquer painting defect have screening the flaw effect while, do not influence finish paint
The effect of layer script.
After having sprayed mixture, according to the requirement to the brightness of drawing top layer, one layer of coating varnish can be again sprayed, coating can be made
With more preferable dicoration.If not being that work very high can save this step to cosmetic requirement, it is not used in spraying Lacquer finish
Varnish.
Spraying is dried after finishing, you can obtain high-quality coating.
