部品の静電塗装方法に関する。Detailed Description of the Invention A1 Object of the Invention (1) Industrial Application Field The present invention provides a method for applying a conductive primer to a part of the surface of a synthetic resin component, a part of which is set as a non-painting area, excluding the non-painting area. The present invention relates to an electrostatic coating method for synthetic resin parts that must be electrostatically coated with a top coat C after painting.

である。(2) Conventional technique (i) Conventionally, the method of electrostatically coating the surface of synthetic resin parts with Topcoal I after coating a conductive primer is as follows:
For example, it is known from Japanese Unexamined Patent Publication No. Sho b 1 249570.

During electrostatic painting, a metallic substance such as aluminum foil is tightly fixed on the side opposite to the surface of the synthetic resin part to prevent the decrease in conductivity due to the decrease in the content of the conductive feeler. The aim is to avoid this and obtain good finish quality.

い。On the other hand, to leave the non-painted area unpainted is to apply masking tape to the non-painted area and remove the masking tape after electrostatic painting is completed. , No. 11 method has been used in the past, and if you simply combine this method with the above conventional method, you will need a step of grounding the conductive primer, a step of grounding the metal material, and a step of pasting masking tape. It requires a process of putting on clothes, so it cannot be said that the work efficiency is excellent.

しい。When electrostatically painting the vehicle bumper 1, first of all, as shown in Figure 1 (
As shown in a) and (b), after the vehicle humber 1 is pretreated, a conductive tape 4 is attached to the surface 2 to mask the non-painted 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 can be attached in any way.
Considering the grounding work described later, it is desirable to attach both ends of the conductive tape 4 to the back surface of the +lL dual-use bumper l.

The upper surface of the receiver part 6 is formed to correspond to the shape of the back surface of the east and dual use hamper 1. Therefore, by placing the vehicle damper 1 on the receiver part 6, both ends of the conductive tape 4 are brought into close contact with the receiver U part 6, and the conductive tape 4 is grounded.

This eliminates the need for work and improves work efficiency.
