Process for spraying plastic parts of mobile phone and mobile phone shell made by adopting process

Abstract

The invention discloses a process for spraying plastic parts of a mobile phone. The process comprises the following steps of (1) assembly of an oil injection clamp; (2) cleaning; (3) electrostatic dust collection; (4) spraying of primer; and (5) oil injection on finishing paint. The invention also discloses a mobile phone shell made by adopting the process. The process is easy to operate, the primer of a corresponding color is selected according to the required color effect, the spraying frequency is lowered, the consumption of the pigments is reduced, and the production efficiency is improved, the production cost is lowered; and due to the adoption of the steps of cleaning and electrostatic dust collection, the adhesive force of the primer and the finishing paint is improved, the spraying effect is effectively improved, and the product quality is guaranteed. The mobile phone shell has a reasonable structure; due to the combination of the primer and the finishing paint, the primer is used for showing the required color effect, the finishing paint is used for improving the crash resistance and the wear resistance of the mobile phone shell, and the service life is prolonged. The spraying process is simple, low in cost and convenient to produce, and large-area popularization and application are facilitated.

Description

technical field [0001] The invention belongs to the technical field of spraying, and in particular relates to a spraying process for plastic parts of mobile phones and a mobile phone casing prepared by implementing the process. Background technique [0002] As an important communication tool, mobile phone has become more and more popular in people's daily life, and the mobile phone market also has great potential. With the development of the mobile phone market, consumers have higher and higher requirements for mobile phones. Therefore, the trend of mobile phone production will also be to pay more attention to the appearance design of mobile phones. The appearance of a mobile phone is largely determined by the mobile phone case, which is generally a plastic case. The color matching and gloss effect of the mobile phone case are important parameters for evaluating the appearance of a mobile phone and affect consumers' choices. The spraying of mobile phone plastic parts is an ...

Problems solved by technology

[0003] At present, the traditional spraying process of plastic parts of mobile phones is complicated. The method of processing the color of the mobile phone shell is to add pigments to the bottom and middle layers of the coating to achieve the purpose of color

Because the pigment is added to the two coatings, the pigment consumption is relatively large, and the number of spraying is more, which not only reduces the production efficiency, but also increases the production cost. In addition, it also reduces the adhesion between the coatings and is prone to premature fading. The phenomenon of paint affects the quality of the mobile phone shell
