A kind of soft and hard integrated electronic product shell and its preparation method

Abstract

The invention provides a soft and hard integrated electronic product casing, which comprises: a rigid part composed of metal foam and a flexible part composed of polymer elastic body; the foam metal and the polymer elastic body are fixedly connected. The housing of the electronic product provided by the present invention adopts metal foam to provide a rigid framework, which has excellent rigidity. At the same time, polymer elastomer is fixedly connected with metal foam. The locking force formed by the interpenetration of the two makes the combination of metal and elastomer very strong. , not easy to disengage. Moreover, the appearance of the housing can be an integrated elastic body, which can maintain the consistency of the appearance effect and the hand feeling.

Description

technical field [0001] The invention relates to the technical field of electronic product shells, in particular to an electronic product shell integrating soft and hard parts and a preparation method thereof. Background technique [0002] Flexible electronic technology is an emerging electronic technology that manufactures organic / inorganic material electronic devices on flexible / ductile plastic or thin metal substrates. , national defense and other fields have broad application prospects, such as flexible electronic displays, organic light-emitting diodes (OLEDs), printed RFID, thin-film solar panels, and electronic skin patches (Skin Patches). [0003] The flexible bending characteristics of flexible electronic products put forward special requirements for the product shell. Some designated areas of the shell are required to be rigid and inelastic, while other areas are required to be soft and elastic. [0004] In the prior art, the metal insert injection molding method i...

AI Technical Summary

Problems solved by technology

[0004] The existing technology generally adopts the method of metal insert injection molding to connect the thermoplastic elastomer and the high-rigidity plate by injection molding. However, due to the small contact area between the thermoplastic elastomer and the high-rigidity plate in this technology, the seam is easily broken

[0005] There is also a technology that combines thermoplastic elastomers and metal sheets through the nano-injection molding (NMT) process. After the surface of the metal substrate is treated with T, the plastic is directly injection-molded on the metal surface, so that the metal and the plastic are integrally formed, but this technology In the prepared shell, the elastic body is easily deformed by force and detached from the micro-nano holes, so that the elastic body is separated from the metal plate
