Abstract
The invention discloses a kind of coating process of arrangements for automotive doors, including：Step 1：Handled before carrying out priming paint on arrangements for automotive doors substrate layer；Step 2：Electrostatic powder coating is carried out to the arrangements for automotive doors, the coating is colored paint；Step 3：Clear dope layer is coated with the coating upper strata；Step 4：To the arrangements for automotive doors copper coating；Step 5：Cured and polished；Wherein, the temperature in the curing process is 190~210 DEG C, and hardening time is 0.5~1h.The coating process for the automobile component that the present invention obtains, changes the method for the prior art on automobile component application, simplifies production stage, saved cost and time.By copper plating treatment, the adhesive force of coating and aluminium alloy is enhanced.The characteristic being had by oneself additionally, due to colored paint composition, then make it that automobile component is dust-proof, anti-corrosion；This coating process has also saved cost to a certain extent for the rational deployment of solvent at the same time.
Description
Technical field
The present invention relates to automobile interior trim production field, more particularly to a kind of coating process of arrangements for automotive doors.
Background technology
Application is last procedure of arrangements for automotive doors production, and the purpose is to improve corrosion resistance and U.S. of arrangements for automotive doors
Sense.Aluminium alloy wheel hub is by machining etc. after the completion of critical process, it is contemplated that aluminium alloy wheel hub condition ratio in actual use
It is poor, the influence factor such as aoxidize in atmosphere in order to reduce aluminium alloy and achieve the purpose that beauty, so to the painting after application
Layer performance has higher requirement.
At present, in the application to arrangements for automotive doors, its coating process is often complex, complex steps, expends larger
Manpower and materials.In addition when passivation effect is bad in preceding processing, may result in needs offer largely to supply powder amount in spraying
It just can guarantee that spraying is completely and uniform, cause to waste.In view of the above-mentioned problems, it is urgent to provide a kind of Automobile by those skilled in the art
The coating process of door.
The content of the invention
To solve the above problems, the present invention provides a kind of coating process of arrangements for automotive doors, including：
Step 1：Rough surface processing is carried out in arrangements for automotive doors substrate layer so that its rough surface is uneven；
Step 2：Electrostatic powder coating is carried out to the arrangements for automotive doors, the coating is colored paint；
Step 3：Clear dope layer is coated with the coating upper strata；
Step 4：To the arrangements for automotive doors copper coating；
Step 5：Dried, cured and polished.
Preferably, the drying is performed 5-60 minutes in 70 DEG C.
Preferably, the spray pressure of the electrostatic powder coating is 0.3MPa, electrostatic potential 34KV, and spray time is
6s。
Preferably, the drying is performed 5-60 minutes in 80 DEG C.
Preferably, the drying is performed 5-60 minutes in 90 DEG C.
The present invention includes at least following beneficial effect：The coating process for the automobile component that the present invention obtains, changes existing
The method on automobile component application in technology, simplifies production stage, has saved cost and time.By copper plating treatment,
Enhance the adhesive force of coating and aluminium alloy.The characteristic being had by oneself additionally, due to colored paint composition, then enable automobile component
Enough dust-proof, anti-corrosions；This coating process has also saved cost to a certain extent for the rational deployment of solvent at the same time.
Embodiment
The present invention provides a kind of coating process of arrangements for automotive doors, including：
Step 1：Rough surface processing is carried out in arrangements for automotive doors substrate layer so that its rough surface is uneven；
Step 2：Electrostatic powder coating is carried out to the arrangements for automotive doors, the coating is colored paint；
Step 3：Clear dope layer is coated with the coating upper strata；
Step 4：To the arrangements for automotive doors copper coating；
Step 5：Dried, cured and polished.
The drying is performed 5-60 minutes in 70 DEG C.
The spray pressure of the electrostatic powder coating is 0.3MPa, electrostatic potential 34KV, spray time 6s.
The drying is performed 5-60 minutes in 80 DEG C.
The drying is performed 5-60 minutes in 90 DEG C.
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed
With it can be applied to various suitable the field of the invention completely, can be easily for those skilled in the art
Realize other modification, therefore under the universal limited without departing substantially from claim and equivalency range, it is of the invention and unlimited
In specific details and shown here as the embodiment with description.
