Embodiment Construction
[0022] The preferred embodiments of the present invention will be described in detail below.
[0023] The method for multi-color spraying of the present invention and the parts after spraying thereof, as shown in FIG. 1, adopts a method of sharing primer, and simplifies the steps of two-color spraying, and also solves the problem that the interface of two colors cannot be separated. deal with difficult problems. In two-color spraying, to achieve high-gloss UV and bright color effects, it is necessary to have a primer with good quality to deposit, the method of the present invention adopts a primer technology, so that the interface is treated once, and then in the subsequent process , Utilize the high hardness characteristics of high-gloss UV to support the completion of the production process of PU paint, improve product quality and enable mass production. The present invention can be widely used for two-color and multi-color spraying on plastics, metals and other materials. ...
