Problems solved by technology

However, for the plastic exterior parts of mobile phones, surface treatment such as spraying or painting is usually required. When the wall thickness of the exterior parts is processed to be thin, problems such as bursts and cracks are easy to occur on the treated surface layer; The complicated post-processing process will increase the deformation of the exterior parts, which will easily cause the cracking of the paint, which will seriously affect the appearance of the exterior parts and increase the defective rate of the product.
[0003] In order to solve the cracking problem of the surface layer of the appearance part, it is pointed out in related technologies that only the method of increasing the size of the appearance part or thickening the wall thickness of the appearance part can be used to reduce the amount of force deformation of the appearance part, thereby avoiding surface cracking. Layer cracking, however, this solution can no longer promote the development of thinner and lighter mobile phones

Abstract

The invention discloses a terminal, a shell, a middle frame, and a processing method of the middle frame. The middle frame is used in the terminal, and comprises a middle frame body, wherein the middle frame body is processed with at least a UV painting layer which comprises polyurethane acrylate elastomer resin. The obtained middle frame has good tenacity in surface coat and is not prone to craze, and the yield is high.

Description

technical field [0001] The invention relates to the technical field of terminal equipment, in particular to a terminal, a casing, a middle frame and a processing method for the middle frame. Background technique [0002] Some mobile phones in the related art pursue a light and thin appearance design, thus requiring the appearance parts and internal parts of the mobile phone to be correspondingly thinner. However, for the plastic exterior parts of mobile phones, surface treatment such as spraying or painting is usually required. When the wall thickness of the exterior parts is processed to be thin, problems such as bursts and cracks are easy to occur on the treated surface layer; The complicated post-processing process will increase the deformation of the exterior parts, which will easily cause the cracking of the paint, which will seriously affect the appearance of the exterior parts and increase the defective rate of the product. [0003] In order to solve the cracking pro...
