[Prior Art and Problems] Topcoating includes air spray coating and electrostatic coating, but electrostatic coating is superior to air spray coating in terms of coating efficiency.
It is widely practiced. The principle of the electrostatic coating method is that a grounded object is used as a counter electrode, and a high voltage is applied to the discharge electrode provided in the electrostatic coating machine to charge the atomized paint,
It is a method of flying on the line of electric force formed between both electrodes and applying it to the object to be coated, which is often used when the object to be coated is a product made of metal such as iron or aluminum. .

Recently, however, automobile bumpers and the like have been made plastic, but in this case, electrostatic coating is very difficult because the product itself has no conductivity. Therefore, the method currently used is to dissolve the surfactant in water or alcohol and apply it to the object to be coated to give it a slight conductivity, or to add a conductive pigment such as carbon to the paint itself. As a conductive primer, a method has been performed in which this is applied to form a conductive coating film to enable electrostatic coating of top coating.

However, the method of applying the surfactant has a small film thickness, so that unevenness is likely to occur and uniform lines of electric force may not be formed, resulting in defective coating. Further, in the case of a conductive primer coating, mixing of a conductive pigment may impair the coating film performance, and the primer itself cannot be electrostatically coated. Therefore, air spray coating is often used for coating plastics at the expense of coating efficiency.

In order to solve these problems, Japanese Patent Publication No. 4-24114 discloses that a ground electrode is provided at a position close to, but distant from, the rear surface of a resin molded product held by an insulator. , An electrostatic coating device for performing electrostatic coating is disclosed. This device has the effect that electrostatic coating can be performed on the surface of a non-conductive resin molded product without any special conductive treatment, but the ground electrode is arranged separately from the object to be coated. Therefore, it was not possible to apply a uniform coating because the electrode shape could not be adapted to the resin molded product having a complicated shape that is continuously moving.

When the jig configured as described above is used for the electrostatic coating of the resin molded product, as shown in FIGS. 1 and 2, the resin molded product 6 and the jig 2 are electrostatically coated in the fitted state. Therefore, riding on the lines of electric force formed between the discharge electrode of the electrostatic coating machine (not shown), the atomized and charged paint flies toward the resin molded product 6 and collides with it. Therefore, the coating efficiency is dramatically improved compared to air spray coating. Also, if paint adheres and accumulates on the edges or holes of the jig, you can easily replace it by replacing the conductive thin film used for conductive treatment or the used paper stuck on the surface of the jig mixed with conductive pigment. Can be repaired.

In FIG. 1, a bumper as an object to be coated is a polypropylene injection-molded product having a thickness of 3 mm and a surface area of about 3 m. Before being electrostatically mounted, the bumper is optionally treated with a water-based cleaning agent or washed with alcohol. After that, normal static elimination processing is performed. The static elimination processing may use a dedicated static elimination machine, but may be activated by corona discharge. The bumper after the cleaning process is transferred to the electrostatic coating jig 2 attached to the transportation platform 50 and sent to the electrostatic coating chamber by a transportation conveyor (not shown). The electrostatic coating machine may be either an electric atomization type or an air atomization type. As the paint, either petroleum solvent-based paint or water-based paint can be used. The distance between the electrostatic coater and the article to be coated may be a usual 20-40 cm. The number of painting machines and robots,
As in the case of normal electrostatic coating, it is necessary to test and confirm the discharge amount and the method of moving the coating machine in advance according to the object to be coated. The coated object is moved to the drying step while being placed on the jig. The drying process is usually at 80 ° C to 120 ° C for 2
Heat for 0 minutes. Therefore, the jig must be appropriately reinforced to withstand the temperature.

As shown in FIG. 1, the electrostatic coating jig according to the present invention comprises an electrostatic coating jig body 2 and a support frame 4 as an accessory. As shown in FIGS. 1 and 2, the jig body 2 has a substantially similar shape so as to fit on the back surface of the resin molded product 6, and therefore the surface area of the resin molded product and the surface area of the jig are substantially equal. . However, the convex portions 10 and the grill 14 on the surface of the resin molded product 6 do not have to have similar shapes, and may be flat surfaces. In this case, since the lines of electric force do not concentrate on the convex portion of the resin molded product, uniform coating can be performed. Further, for the small protrusion 16 on the back surface of the resin molded product 6, two jig surfaces 30 are formed as shown in FIG. 1 to sandwich the protrusion. In this case, it is not necessary to make the curvature of the jig curved surface extremely small and to inscribe it in the corner portion. On the contrary, if it is made too small, the lines of electric force are concentrated and uniform coating cannot be performed, which is not preferable. In addition, the end of the resin molded product 6 and the end 1 of the hole 12
As shown in FIG. 1, the surface of the jig main body 2 corresponding to No. 3 is a curved surface 34, 32 inscribed in the back surface of the resin molded product end 8 or hole end 13 and the normals 18 or 20 to the end. Is formed. These inscribed curved surfaces do not necessarily have to be accurate inscribed curved surfaces, and the size of the jig is made slightly smaller than the resin molded product so that the jig is hidden by the resin molded product to reduce the adhesion of paint. Therefore, it is preferable. Further, as shown in FIG. 2, the grill part may be formed by forming a jig in a plane, and it is not necessary to have a special complicated shape. This is because the lines of electric force reach the inside of the grill by the jig. By forming in this way, not only a uniform coating can be obtained, but even if the coating that has passed through the holes is deposited, it can be ignored for a long period of time.

As the material of the jig body 2, FRP resin is used. However, it is preferable to use a resin mixed with a conductive pigment, because the conductivity and heat resistance can be obtained. For the shaping using the FRP resin, the resin shaped article itself can be used as the mother mold. This is because the resin molded product is flexible and has poor precision as a mother mold, but in this case, strict precision is not necessary.

When the FRP resin forming the jig does not contain a conductive pigment, the surface of the jig must be covered with a conductive thin film after the main body 2 of the jig is formed. A metal foil such as an aluminum foil can be used as the conductive thin film. In this case, as shown in FIG. 3, a metal foil such as an aluminum foil 42 or an aluminum tape may be attached to the entire surface of the jig body 2. Further, a grounding terminal 44 formed of an aluminum foil 42 and a copper plate is connected to a conductor 46.
It is preferable to make a connection by the method described above, and then measure the resistance value to confirm that it is grounded. Further, a conductive coating material 48 containing aluminum powder, copper powder, or zinc powder as a conductive treatment material.
May be coated on the entire surface of the jig body 2 formed by FRP. Alternatively, a metal thin-film deposited resin thin film may be used. In either case, the conductivity may be confirmed.

EFFECTS OF THE INVENTION According to the present invention, a resin molded product having a complicated shape is subjected to uniform electrostatic coating because electric lines of force are concentrated on the object to be coated as a whole and are not concentrated on a local portion of the object to be coated.

In addition, it greatly improves the coating efficiency. Further, since the resin molded product itself is used as a mother mold for manufacturing the jig and is formed by FRP, it can be manufactured easily and at low cost. Further, since the conductive thin film is used for the conductive treatment, replacement and repair can be easily performed even if the paint adheres to the end portion. Further, since the resin molded product itself is used as the molding die of the jig, the molding can be carried out inexpensively and easily.

As the material of the jig body 2, FRP resin is used. However, it is preferable to use a resin mixed with a conductive pigment, because the conductivity and heat resistance can be obtained. In molding using FRP resin, the resin molded product itself can be used as the mother mold. This is because the resin molded product is flexible and the precision of the mother die is poor, but in this case, strict precision is not necessary.
