共に、防爆の為の多額な設備投資を強いられていた。(c) Problems to be solved by the invention As mentioned above, metallic paint was applied by applying two or more layers of metallic paint.
Because metallic paint contains aluminum powder, it is easily charged and ignited, so it cannot be used with automatic paint machines. For this reason, painting work had to be done manually using air spray, requiring a great deal of manpower to apply two coats, and requiring a large investment in equipment for explosion-proofing.

) After the surface is treated with a chemical conversion film (6), a non-metallic paint (7) is applied by automatic electrostatic coating to provide an undercoat, and then a topcoat is applied with a metallic paint (8) by air spray. At this time, non-metallic paint (7)
is a similar color to the metallic paint (8).

が図れる。(*) Function According to the present invention, the base color of the outer box does not show through due to the non-metallic paint of a similar color. Therefore, the metallic feel of the overcoated metallic paint is not impaired. Furthermore, since the undercoating with non-metallic paint is an automatic operation, significant labor savings can be achieved.

FIG. 1 shows a perspective view of an outer box (1) of a refrigerator to which the present invention is applied. The outer box (1) consists of a top surface (2) and left and right side surfaces (3) and (4) by bending a strip steel plate, and the lower ends of the left and right sides (3) and (4) are welded to the front plate (5). Connect and configure by.

塗料（８）と同系色のものを用いる。FIG. 2 shows an enlarged sectional view of the outer box (1) at a proper location. First, a chemical conversion film (6) made of zinc phosphate or the like is formed on the outer surface of the outer box (1) to increase the adhesion of the paint, and then a non-metallic paint (7) made of a non-metallic paint such as urethane paint is applied on top of it. A metallic paint (8) in which aluminum powder is mixed with enamel is further applied thereon. The unique shine of this metallic paint (8) improves the beauty of the outer box (1) and increases the added value of the refrigerator.In addition, the non-metallic paint (7) has a similar color to the metallic paint (8). Use the one.

乾燥しているので短期間で終了できる。Next, the procedure for painting the outer box (1) will be explained using the flowchart in FIG. 3 and FIG. 4. Since the steel plate constituting the outer box (1) is coated with oil in advance to prevent contamination, it is degreased with a predetermined degreasing liquid, and then this degreasing liquid is removed by washing with water. Next, a chemical conversion coating treatment is performed to form the above-mentioned chemical conversion coating (6) on the outer surface of the steel plate, and then the excess treatment liquid is washed off with water, and then the steel plate is drained and dried. After completing the above, the non-metallic paint (7) is then applied with an undercoat by automatic electrostatic coating in a predetermined coating booth, and dried at -1 room temperature. At this time, by drying once, the occurrence of surface irregularities is suppressed and deterioration of gloss is prevented. After this drying is completed, a top coat is applied by hand-spraying the metallic paint (8), which is heated and dried to harden the baking, and the surface condition is inspected. In this case, heating and drying can be completed in a short period of time since the undercoat has already dried.

り塗装の良好なメタリック感を維持できるものである。The difference from the conventional procedure in the above procedure is explained in Fig. 4. Conventionally, both the undercoat and the second coat were done by hand with air spray, but in the present invention, the undercoat is automatically and statically applied. Since it can be done by electro-coating, it can greatly improve work efficiency and save labor. In addition, since the non-metallic paint (7) is of a similar color to the metallic paint (8), the base color of the outer box (1) will not be seen through, and the good metallic feel of the top coat can be maintained. It is.
