Embodiment Construction
[0021] Preferred embodiments of the present invention are described in detail below.
[0022] The method for multi-color spraying of the present invention and the parts after spraying thereof, as shown in Figure 1, has adopted a kind of method of common primer, and has simplified the step of two-color spraying, also solved simultaneously the interface of two kinds of colors cannot Problems to deal with. In two-color spraying, since high-gloss UV and bright color effects are to be achieved, it is necessary to have a good-quality primer for storage. The method of the present invention adopts a process of primer, so that the interface is treated once, and then in the subsequent process , using the high hardness characteristics of high-gloss UV to support the completion of the production process of PU paint, which improves the product quality and can be mass-produced. The present invention can be widely used in two-color and multi-color spraying on plastics, metals and other mate...
