Abstract

The invention discloses a mobile terminal component. The mobile terminal component comprises a ceramic component, a plastic component and a bonding layer; the bonding layer is used for connecting theceramic component and the plastic component; a gravel layer is arranged on the surface, making contact with the bonding layer, of the ceramic component, and the particle size D50 of gravel in the gravel layer ranges from 20 m to 400 m. According to the component, the binding force of the ceramic component and the plastic mold is high after injection molding, no offset or gap exists at the joint ofthe ceramic component and the plastic component, the problem that fine substances such as dust and scurf are adsorbed and embedded can be effectively avoided, and the texture and the aesthetic feeling of the ceramic-plastic composite component can be improved. The invention further provides a preparation method of the mobile terminal component, and the preparation method is simple in technological process, high in operability and suitable for mass production of the injection molding ceramic components in the mobile terminal mold.

Description

technical field [0001] The invention relates to the technical field of terminals, in particular to a mobile terminal component and a preparation method thereof. Background technique [0002] Nowadays, electronic products such as mobile phones, smart watches, and smart appliances have become an indispensable part of people's daily life. The different needs of consumers have also prompted mobile phone manufacturers and major suppliers to continue to innovate and create more products that can satisfy users' aesthetics and practicality. electronic product. With the rapid development of communication technology, the era of 5G is getting closer and closer to us. The first technical feature of 5G is millimeter wave. The shorter the wavelength, the higher the transmission frequency and the faster the transmission speed. Due to the shielding and interference effect of the metal back cover on the signal, it will limit the transmission speed, so that in the current mobile terminal ind...
