Mobile phone case capable of accommodating standby battery and manufacturing process thereof

Abstract

The invention relates to the technical field of mobile phone cases, in particular to a mobile phone case capable of accommodating a standby battery and a manufacturing process thereof. The mobile phone case comprises a shell body and a groove which is formed in the shell body and used for holding the standby battery, wherein the shell body comprises a first PC (Polycarbonate) plastic layer, a second PC plastic layer and a composite material layer which is bonded with the first PC plastic layer and the second PC plastic layer respectively and can bend and rebound; the first PC plastic layer, the composite material layer and the second PC plastic layer are arranged on a same layer, and construct an inner layer of the shell body; and the shell body further comprises a low-temperature silica gel layer covering the inner layer, and an adhesive layer which is arranged between the inner layer and the low-temperature silica gel layer. Through the composite material layer which can bend and rebound, a mobile phone can be put into the mobile phone case conveniently. Through adoption of the manufacturing process, very great adhesive force can be generated between silica gel and PC plastic or certain composite materials. Moreover, the manufacturing process has the characteristics of simple process, low production cost and suitability for large-scale production.

Description

technical field [0001] The invention relates to the technical field of mobile phone protective cases, in particular to a mobile phone protective case that can be equipped with a spare battery and a preparation process thereof. Background technique [0002] Along with the application of mobile phone more and more widely, in order to pursue attractive in appearance and play protective effect to mobile phone, mobile phone protective cover is also more and more subject to liking of consumer. However, the mobile phone protective case in the prior art generally does not have a space designed to place a spare battery, which makes it inconvenient for mobile phone users to use the mobile phone. In addition, even if the mobile phone protective case in the prior art is provided with a space for assembling a spare battery, it is usually difficult to put the mobile phone into the mobile phone protective case after the spare battery is assembled in the mobile phone protective case, that i...

Problems solved by technology

However, the mobile phone protective case in the prior art is generally not designed to place a spare battery space, which causes the mobile phone user to be inconvenient in the process of using the mobile phone.

In addition, even if the mobile phone protective case in the prior art is provided with a space for assembling a spare battery, it is usually difficult to put the mobile phone into the mobile phone protective case after the spare battery is assembled in the mobile phone protective case, that is, the consumer needs to pass through Only a large force can put the mobile phone into the mobile phone protective case, which will cause difficulty in operation on the one hand, and easily cause wear and tear on the mobile phone on the other hand

[0003] In addition, in the process of preparing mobile phone protective cases in the prior art, there is often a problem that it is difficult to bond well between silica gel and PC plastic or some composite materials, especially the silica gel that needs to be vulcanized at a low temperature of about 110°C, and it is even more difficult to ensure the bonding between silica gel and PC plastic. Or some composite materials can have better adhesion
