Abstract

PURPOSE:To obtain a good metallic coating film without darkening by applying a metallic coating compound using a rotary atomizer type coating machine with a grooveless atomizer head and reducing the rotating speed of the atomizer head. CONSTITUTION:When a grooveless atomizer head 5 is rotated at a relatively low speed, a metallic coating compound is discharged from the discharge edge of the atomizer head 5 in a film form without being shredded by cusps. Shaping air is ejected from an air nozzle 4 to the coating film (b). It is therefore difficult for the shaping air to pass without contacting coating compound particles, and large kinetic energy of the shaping air is given to the particles, increasing the particle size as well as the flight velocity of the particles. As a result, when the particles hit the coating surface, they are crushed, and the luster pieces in the particles are moved to be arranged in parallel with the coating surface to prevent darkening. Since a clear coating compound has a large viscosity, very fine coating particles should be prepared. Therefore, the rotary atomizer type coating machine with a grooved atomizer head is to be used.

2. Description of the Related Art Conventionally, as a coating machine, an air spray type and a rotary atomizing type are known. The rotary atomizing type coating machine has a bell-shaped atomizing head that rotates at high speed, and the paint supplied to the atomizing head is thin film-shaped along the inner surface of the atomizing head due to the centrifugal force of rotation of the atomizing head. Is directed to the discharge edge, and the paint is discharged as a cusp (liquid thread) from the discharge edge and atomized. In order to stably generate a large number of thin cusps, a groove for subdividing the flow of the film-shaped paint is formed at the discharge edge of the atomizing head (see Japanese Utility Model Publication No. 63-14917). ).

[0003] In the case of metallic coating, conventionally, it is general to apply a metallic paint by an air spray type coating machine and then a wet-on-wet clear coating by a rotary atomization type coating machine. The reason why the clear paint is applied with a rotary atomizer is to improve the coating efficiency.
When the metallic paint is applied by a rotary atomization type coating machine, so-called darkening occurs in which glossy pieces in the coating film are irregularly arranged and appear dark. That is, since the flight speed of the coating particles is high in the air spray type, when the coating particles hit the coating surface, they are greatly crushed,
The glossy pieces that floated irregularly in the coating particles were moved and oriented parallel to the coating surface.However, in the rotary atomization system, the flying speed of the coating particles slowed down, so the coating particles hit the coating surface. However, most of them do not collapse, and the glossy pieces remain irregularly oriented, resulting in darkening.

Further, from Japanese Patent Publication No. 59-51868, it is known that both a metallic paint and a clear paint are coated by a rotary atomizing type coating machine. The atomizing head is rotated at an extremely high speed so that the peripheral speed is 120 to 300 m / sec.

When the grooveless atomizing head is used, the metallic paint is not subdivided into cusps and is discharged in the form of a film from the discharge edge of the atomizing head, and shaping air is blown to the film-shaped portion. Therefore, it becomes difficult for the shaping air to pass through between the coating particles, and the coating particles are given a large amount of kinetic energy by the shaping air to increase the flight speed of the coating particles. When colliding, the coating particles are largely crushed, and the glossy pieces in the coating particles are moved and oriented parallel to the coating surface, so that blackening does not occur. still,
Even if a non-grooved atomizing head is used, if it is rotated at a high speed, the paint will not be released in a film form, so it is desirable to rotate at a relatively low speed as described above. Since clear paint has a high viscosity, it is necessary to make the coating particles finer in order to prevent coating defects such as foam bite and to ensure the smoothness of the coating film. A rotary atomizing coating machine that applies clear paint there. The atomizing head of is to have a groove.

If the metallic paint is applied only once to a desired thickness, the soft-painted film immediately after application will not be crushed and the paint will not be crushed. In order to prevent this, it is necessary to increase the viscosity of the paint, which makes it difficult for the glossy piece to move and the orientation of the glossy piece is poor. On the other hand, if the metallic paint is applied several times as described above, the viscosity of the paint can be made relatively low, the glossy pieces can be easily moved, and the coating is hardened to some extent by evaporation of the solvent after the previous application. Since the coating particles collide with the film, the coating particles are largely crushed and the orientation of the glossy pieces is improved.

The above-mentioned groove is not formed in the atomizing head 5 of the rotary atomizing type coating machine shown in FIG. 2 (a), so that the discharge edge of the atomizing head 5 is shown in FIG. 2 (b). As described above, the paint is discharged in the form of a film, and the paint is scattered from the film-like portion b and atomized into relatively large coating particles. At this time, the shaping air is blown onto the film-shaped portion b, and it becomes difficult for the shaping air to pass through between the coating particles, so that a large motive energy due to the shaping air is given to the coating particles and the flying speed of the coating particles is increased. 2A, the axial distance L1 and the radial distance L2 between the discharge edge of the atomizing head 5 and the air nozzle 3 are L1 = 10 to 20 mm, respectively.

Very good. When the peripheral velocity of the grooveless atomizing head 5 is less than 30 m / sec, the paint does not atomize well, and when the peripheral velocity exceeds 80 m / sec, the paint is not released in the form of a film.
