Problems solved by technology

[0006] The three-spray method of the prior art is different for the formulations of primers, intermediate paints, and top coats used in UV paints and PU paints, and there is no inconvenience in using them separately on a part; but for doing it on the same part In two-color spraying, for example, one part of the same part uses a certain color for a high-gloss effect, and the other part uses another color for a rubber paint effect, which will result in many steps, complicated processes, high production costs, and low product yields.

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...

Abstract

The invention discloses a multi-color coating method and a coated part; wherein, the method comprises at least the following steps: a layer of priming paint is coated on the whole face plate; a first middle paint is coated on a first area of the face plate; a first top finish is coated on the first middle paint; a second middle paint is coated on a second area of the face plate, and a second top finish is coated on the second middle paint. Since the method of using the same priming paint when coating two colors, the invention has the advantages of simplified paint coating process and improvedyield rate.

Description

technical field [0001] The invention relates to a spraying production process of plastic parts, in particular to a method for multi-color spraying on plastic parts and parts obtained by the method. Background technique [0002] So far, in the production of communication terminal equipment in the industry, spraying is often used as the casing on plastic parts, such as the casing of mobile phones. And often need the spraying of multiple colors on mobile terminal equipment, especially on the same part. The two-color spraying process on plastic parts mainly uses UV paint (UV paint is the English abbreviation of Ultraviolet Curing Paint, that is, ultraviolet light curing paint, also known as photoinitiated paint, light curing paint) and PU paint (polyurethane paint is a wood paint). A kind of paint with the largest market share can be divided into two-component polyurethane paint and single-component polyurethane paint) and three-spray method for production. [0003] UV paint i...
