Purpose of the invention (1) Industrial application field The present invention applies a conductive primer to a part of the surface of a synthetic resin component, which is set as a non-painting area, except for the non-painting area. The present invention relates to an electrostatic coating method for synthetic resin parts for electrostatically coating a top coat after coating.

を得ようとするものである。(3) Problems to be Solved by the Invention By the way, the above conventional method reduces the amount of conductive filler such as conductive carbon contained in the conductive primer to the extent that deterioration in appearance quality can be avoided. During electrostatic painting, a metal material such as aluminum foil is tightly fixed on the side opposite to the surface of the synthetic resin part to avoid a decrease in conductivity due to a decrease in the content of the conductive filler and to obtain a good finish quality. This is what we are trying to do.

であり、作業効率が優れているとは言えない。 On the other hand, the conventional method for leaving non-painted areas unpainted is to apply masking tape to the non-painted areas and remove the masking tape after electrostatic painting is completed. A simple combination of this and the conventional method described above requires a process of grounding the conductive primer, a process of grounding the metal substance, and a process of pasting masking tape, which results in excellent work efficiency. I can't say that.

望ましい。 When applying electrostatic coating to the vehicle bumper 1, first, as shown in FIGS. Mask area 3. This conductive tape 4 may be made of any material as long as it has conductivity; for example, it may be made of aluminum. Furthermore, as long as the entire non-painted area 3 is masked, the conductive tape 4 may be attached in any way, but considering the grounding work described later, it is necessary to attach both ends of the conductive tape 4 to the vehicle. It is desirable to attach it to the back side of the bumper 1 for use.

The paint truck 5 and the receiving portion 6 are made of conductive metal, and the upper surface of the receiving portion 6 is formed to correspond to the shape of the back surface of the vehicle bumper 1. Therefore, by placing the vehicle bumper 1 on the receiving part 6, both ends of the conductive tape 4 are brought into close contact with the receiving part 6, and the conductive tape 4 is grounded.

Paint the entire surface 2 including the top. This results in
The conductive primer 7 is grounded via the conductive tape 4 and the receiving part 6. After coating this conductive primer 7, the coating truck 5 is introduced into a drying oven (not shown) to dry the conductive primer 7.

を行なうことができる。 After drying the conductive primer 7, a top coat 8 is applied electrostatically over the entire surface of the conductive primer 7, as shown in FIG. At this time, since the conductive primer 7 is grounded via the conductive tape 4, a good electrostatic field can be ensured to perform electrostatic painting.
