Problems solved by technology

[0003] The above method requires color separation and protection of the topcoat in the area to be sprayed and the surrounding area before formal spraying, and regardless of the size of the area to be sprayed, as long as there are multiple colors in the area to be sprayed, each color must be protected one by one , spraying, drying, this method is time-consuming and laborious, not only the preparation time is long, but also the workload is much higher than the formal spraying operation, the entire operation cycle is the same as the color separation of the vehicle topcoat, thus affecting the delivery cycle

Embodiment 1

[0024] In this embodiment, the subway doors of Line 5 are used as the object of partial topcoat color separation spraying. In order to ensure the straightness of the connection between the door ribbon and the car body ribbon, the door color separation is carried out after the car body is assembled. The distribution of color bands on the door is consistent with that on the car body. If the traditional color separation method is used, the operation cycle is the same as the color separation cycle of the car body, thus delaying the production cycle.

[0025] The partial topcoat color separation spraying method of the present embodiment is specifically:

[0026] 1. Set the color separation tape

[0027] Carry out color separation on the door according to the art drawing, that is, set color separation tapes around the edges of multiple areas to be sprayed on the door, so as to divide the color separation boundaries of each area to be sprayed.

[0028] 2. Set up the bracket

Embodiment 2

[0036] In this embodiment, a small area containing multiple colors to be sprayed is used as the object of partial topcoat color separation spraying, and the partial topcoat color separation spraying method is specifically as follows:

[0037] 1. Set the color separation tape

[0038] The edges of multiple areas to be sprayed in the small area are respectively surrounded by color separation tapes, so as to divide the color separation boundaries of each area to be sprayed.

[0039] 2. Set up the bracket

[0040] Cut out multiple sections of protective tape with a width of 50 mm, fold them in half along the length direction (with the adhesive side facing outwards), and surround one side of the two folded protective tapes on the outside of the area to be sprayed (for example, paste fixed on the area where the color separation tape is), and the other side is pasted to form a bracket, which is vertically arranged on a small area with a height of 5cm.

[0041] 3. Protection

Abstract

The invention provides a color separation spraying method for partial finish paint. The color separation spraying method sequentially comprises the steps of arranging color separation adhesive tape on the edges of a plurality of areas to be sprayed in a surrounding mode; arranging vertical supports outside the areas to be sprayed in a surrounding mode; protecting the exterior areas of the areas to be sprayed; spraying the areas to be sprayed; and drying the areas to be sprayed after the areas are sprayed. The color separation spraying method for the partial finish paint has the advantages that the operation is easy and fast, the applicability is high, the operation time can be shortened on the premise of guaranteeing the product quality, and the operation efficiency can be improved.

Description

technical field [0001] The invention relates to a coating method, in particular to a color-separation spraying method of a partial topcoat. Background technique [0002] The topcoat is the final coat of paint, and multiple colors in one area may need to be treated during the topcoat application or rework process. At present, the method of color-separation spraying of partial topcoat is to separate the color of the area to be sprayed according to the spraying sequence of the color-separation topcoat according to the art plan and technical requirements. After retaining the sprayed area of ​​the first color and protecting other areas, the The spraying area of ​​the first color is sprayed with topcoat and forced to dry. After the topcoat of the first color is completely dry, the next area to be sprayed is protected again, and the spraying area of ​​the second color is reserved and other areas are protected. For good protection, spray topcoat on the sprayed area of ​​the second ...
