Conventionally, air coating or air atomization electrostatic coating has been the mainstream method for top coating automobile bodies. This air atomization painting or air-based electrostatic painting is a method that makes the paint into fine particles and can obtain a uniform coating surface.
The coating efficiency is low, requiring a large amount of extra paint, and the amount of paint discharged from the air atomization (electrostatic) paint gun is also small. When painting a large object such as a large object to be coated, the disadvantage is that the fineness of the coating can must be reciprocated.

For this reason, the rotary atomizing electrostatic coating machine method, which has a large paint output and excellent coating efficiency, has recently attracted attention, and is being put into practical use for the intermediate coating, clear topcoat, and solid topcoat of automobile bodies. be. However, this rotary atomization electrostatic coating method was unsuitable for metallic coating, which is considered to be the most difficult of the automotive top coating methods, due to the following points.

Generally, when applying metallic paint, the color tone of the painted skin changes depending on the model of the painting machine even if the same paint is used, and air atomization (¥4
Compared to electrostatic coating, the color tone of the painted surface obtained by rotary atomization electrostatic coating is darker and lacks a metallic feel. This is because the particle size of the paint particles sprayed from the spray head of the rotary atomizing electrostatic paint machine is larger than that of the paint particles from the air atomizing (electrostatic) paint gun. This seems to be because the aluminum particles are finely and uniformly dispersed. For this reason, if a metallic topcoat is applied using a rotary atomizing electrostatic atomizer, there is a problem that the appearance quality of the car body is impaired and is not desirable. After that, if you partially apply correction painting with an air atomization paint machine,
For the above-mentioned reasons, color differences occur in each part of the painted surface, and wrinkles also cause deterioration of the appearance quality of the car body, making it impossible to obtain a car body with a good quality paint surface as a whole.

In this method, metallic colored paint is applied to the entire surface of the car using a rotary atomizing electrostatic gamma 3 coating machine, and then air atomization is applied to the entire painted surface in order to cover up the uniformity of the color tone of the painted skin and the reduction in the metallic feel. It uses a gun to spray an overall mist, making it possible to achieve a painted surface with little color difference and an excellent metallic feel. [2] However, the above coating method has the disadvantage of being uneconomical because air atomization (static 11) coating, which has low coating efficiency, is also used.

The spray head peripheral speed of each coating machine in the first coating zone A is determined by the degree of atomization of the metallic colored paint to be sprayed. The finer the paint particles, the finer and more uniform the aluminum particles in the metallic paint will be, the better the coating surface will be without any metal unevenness, but if the paint particles are too fine, the coating efficiency will be reduced. becomes worse, which is not good.

In addition, if the paint particles are too small, the paint sprayed from the spray head will be atomized and the solvent will not be lost before it reaches the object to be coated. The solvent evaporates and accelerates the drying of the particles, resulting in rough skin (dusty skin).
I don't like it because it causes 7. The spray head peripheral speed of the spraying machine in the first coating zone A is 120 to 300 m7 seconds. This circumferential velocity is reduced to a rotational speed of 30.000 to 75.0 rl Or, p, m with a spray head having a diameter of 80 fTL/sec. If the circumferential speed is less than 120 fn/sec, as described above, it is not possible to ensure the same level of atomization of paint particles as with air atomization, and the metallic feel is impaired, which is not desirable. Also, 3
00 m7 seconds or more is not preferable because the paint becomes too fine and the drying of the paint particles is accelerated, resulting in the generation of dusty skin on the coated surface and a decrease in the coating efficiency.

The spray head circumferential speed of each sprayer in the second coating zone A is set to be slower than the circumferential speed in the first coating zone. Specifically, for example, the peripheral speed is 40 to 120 m7
Seconds. The paint applied in the second painting zone is a metallic clear paint or solid paint, so the paint applied in the first painting zone is
Good coating quality can be ensured even at a circumferential speed that is significantly slower than in coating zone A. From the standpoint of improving coating efficiency, it is better to paint with the spray head peripheral speed as slow as possible as long as it does not impair the exterior quality of the body. 2nd painting zone A
By the rotary atomization electrostatic coating of the metallic clear paint or the solid paint at t, it is possible to change the dusty surface of the paint film of the body 1, which has passed through the first painting zone A1 and has been painted with metallic color, to a smooth paint film surface. can.

As is clear from the above table, in Example 1 (comparison), the peripheral velocity of the spray head in the first step was as slow as 60 ml, so the resulting coating film had poor metal unevenness and metallic feel, and the quality of the coating film deteriorated. Actually, Example 6 (comparison) is an example in which an air atomizing electrostatic coating gun was used in the first step, and although the quality of the coating film obtained according to this example is good, the coating efficiency is 40%. It is extremely low. In Examples 2 to 5 (invention), the metal unevenness and metallic feel of the coating film were good, and the coating efficiency was also as good as that of Example 6.
It can be seen that there is a significant improvement compared to .

As is clear from the above description, in the method of the present invention, the metallic color coating in the first coating process is performed using a rotary atomizing electrostatic coating machine that rotates at high speed, so that the level of metallic color coating is the same as that of air atomization (electrostatic) coating. A coating film with a good metallic feel and no metallic unevenness can be obtained. Therefore, even if correction painting is performed using an air spray gun, no color difference will occur between the correction area and the correction area. In addition, the dust surface of the paint film created by the rotary atomization electrostatic coating of the metallic colored paint is well covered by the rotary atomization electrostatic coating of the clear paint or solid paint in the second painting process, so that a smooth paint film can be obtained. No. It's Kade.
Since the method of the present invention uses a rotary atomizing electrostatic coating machine with excellent coating efficiency in both the first coating process and the second coating process,
This method has the advantage that a coating efficiency superior to that obtained by a combination of air atomization (static ijv) coating and rotary atomization electrostatic coating is obtained, and that it is effective in saving paint.
