Description
Technical field
The present invention relates to the coating process of a kind of colored wheel rim.
Background technology
In order to meet the hobby of people and the pursuit to individual character, the wheel rim pattern of motorcycle is the most diversified, and it is prized
Color aluminium alloy wheel rim enjoys liking of people due to advantages such as intensity height, light weight.The actually used ring of aluminium alloy wheel rim
Border weather conditions are poor, the most do not lose attractive in appearance for strengthening the weather resistance of wheel rim simultaneously, and aluminium alloy wheel rim colour application is very
Important link.The spraying coating process that wheel rim uses at present is pre-treatment-drying-spray-applied primer (part can save this step)-spraying
Finish paint-solidification-finished product packing, coating performance is poor, and the aesthetics of product appearance is relatively low, it is difficult to meet day by day carrying of people
High outward appearance is pursued.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention provides the coating process of a kind of colored wheel rim, improves colored wheel rim
The pliability of coating, adhesive force, weather-proof ability, and colored wheel rim surface aesthetics is higher.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of coating process of colored wheel rim, it is characterised in that: comprise the following steps: a), a pre-treatment, including pre-defat,
Main defat, neutralization, chromaking, pure water clean；B), dry, the workpiece after a pre-treatment is carried out heating, drying moisture, heating temperature
Degree is 120 ± 10 DEG C；C), spray-applied primer, priming paint film thickness is more than 20 μm；D), solidifying priming paint, use heated baking side
Formula solidification priming paint；E), machine bright of car, use lathe to process bright on wheel rim；F), secondary pre-treatment, including pre-de-
Fat, main defat, neutralization, chromaking, pure water clean；G), dry, the workpiece after secondary pre-treatment is carried out heating, drying moisture, adds
Hot temperature is 120 ± 10 DEG C；H), spraying the colored varnish, colored varnish film thickness is more than 20 μm；I), the colored varnish solidification, employing adds
The mode that baking the affected part after applying some drugs is baked solidifies the colored varnish.
As the improvement of technique scheme, in described step a and step f, the conductance of the pure water used by pure water cleaning
Rate is not more than 20, and pure water cleans and carries out in spray mode, and spray pressure is 0.1-0.25MPa.
As the further improvement of technique scheme, in described step c and h, spray gun distance workpiece 30-40mm, connect
Touch coating cloud sectional area S >=100 square centimeter of workpiece.
Improving further, in described step d and i, paint film temperature is 150 ± 10 DEG C, and baking time is 30-45min.
Improving further, in described step e, lathe rotating speed is 1000-1600rpm, feed speed 0.28mm/r, processes two
Time, first pass amount of feeding 0.3mm, second time amount of feeding 0.2mm.
The invention has the beneficial effects as follows: use celluloid paint as surface lacquer, both can protect priming paint and bright, and can carry again
Weather-proof, the anti-wear performance of high color wheel rim, makes colored wheel rim more attractive, durable, and the colored wheel rim that this coating process obtains is being coated with
On the premise of pliability, adhesive force and the weather resistance of layer all improves, further increase specious, the various shapes of product,
The outward appearance meeting people instantly is pursued.
Detailed description of the invention
A kind of coating process of colored wheel rim, it is characterised in that: comprise the following steps: a), a pre-treatment, including pre-de-
Fat, main defat, neutralization, chromaking, pure water clean, and pre-defat adds water allotment in 2% ratio with JM-90 degreasing agent, water temperature room temperature, always
Basicity 5-6 point；Main defat adds water allotment in 2% ratio with JM-6 degreasing agent, and water temperature room temperature, total alkalinity is 16-29 point；Neutralize with
JM-23 nertralizer adds water allotment in 0.1% ratio, and water temperature room temperature, pH value is in the range of 7.0-9.0；Chromaking is with JM-56D oxidant
Add water allotment in 1.5% ratio, water temperature room temperature, titration counts 4.5-5.0, surveys pH value in the range of 2.5-3.5, if going beyond the scope,
PH value adjusts with JM-56B, and titration is counted and adjusted with JM-56D oxidant；Pure water is washed, by pure water displacement apparatus, electrical conductivity≤
20.Cleaning and carry out in spray mode, spray pressure is 0.1-0.25MPa；B), dry, to the workpiece after a pre-treatment
Carrying out heating, drying moisture, heating-up temperature is 120 ± 10 DEG C；C), spray-applied primer, priming paint film thickness, more than 20 μm, sprays paint
