Problems solved by technology

[0003] Most of the traditional mobile phone protective cases are made of hard rubber materials. Therefore, common mobile phone cases have defects in shockproof performance, and mobile phone cases made of hard rubber components are not delicate and comfortable enough in terms of feel and texture.
[0004] At present, the mobile phone protective case made of the combination of hard rubber material and soft rubber material has not yet been found in the patent literature, and it is still blank.

Embodiment 1

[0018] A manufacturing process of a mobile phone protective cover. First, at 180°C, a synthetic resin of hard rubber material ABS with a proportion of 30% is backlogged, and then the flake resin is injected into the mobile phone cover mold to form the inner hard shell of the mobile phone cover; secondly , At 150°C, accumulate 70% of the synthetic resin of the soft rubber material TPR, and then inject the sheet-shaped resin into the mold, and release the mold to form the outer soft shell of the mobile phone case, and finally the finished product.

Embodiment 2

[0020] At 350°C, accumulate 90% of the synthetic resin of the hard rubber material PP, and then inject the flake resin into the mobile phone case mold to form the inner hard shell of the mobile phone case; secondly, accumulate 10% of the soft rubber at 260°C The material is TPU synthetic resin, and then the flake resin is injected into the mold, and the mold is removed to form the outer soft shell of the mobile phone case, and the final product is finished.

Embodiment 3

[0022] At 250°C, backlog the synthetic resin of the blend of hard rubber material ABS and PC with a proportion of 43%, and then inject the flake resin into the mobile phone case mold to form the inner hard shell of the mobile phone case; secondly, backlog at 200°C The synthetic resin of the soft rubber material PU with a proportion of 57% is injected into the mold to form the outer soft shell of the mobile phone case, and the final product is finished.

Abstract

The invention provides a handset protective sleeve and preparation method thereof. The handset protective sleeve comprises 30-90% mass ratio of ebonite material and 10-70% mass ratio of flexible glue material, wherein the ebonite material is one material selected from ABS, PC, or PP or mixture of ABS and PC; the flexible glue material is one material selected from TPR, TPE, TPU or PU. The preparation method thereof comprises the following steps: pressing 30-90% mass ratio of synthetic resin of any one ebonite material selected from the ABS, PC, or PP or mixture of ABS and PC at 180-350 degree and pouring the flaky resin into the mould to form inner-layer hardshell; pressing 10-70% mass ratio of synthetic resin of any one flexible glue material selected from the TPR, TPE, TPU or PU at 150-260 degree and pouring the flaky resin into the mould to form outer-layer softshell; obtaining the finished product.

Description

technical field [0001] The invention relates to a mobile phone protective case and a manufacturing process thereof. Background technique [0002] As we all know, the mobile phone protective case plays a vital role as the protective device of the mobile phone. A good mobile phone case can protect the service life of the mobile phone, especially for some high-end mobile phones, the role of the mobile phone protective case is more obvious. [0003] Traditionally used mobile phone cases are mostly made of hard rubber materials. Therefore, common mobile phone cases have defects in shockproof performance, and mobile phone cases made of hard rubber components are not delicate and comfortable enough in terms of feel and texture. [0004] At present, the mobile phone protective cover manufactured by combining hard rubber material and soft rubber material has not yet been found in the patent literature, and is still blank. Contents of the invention [0005] The purpose of the pres...
