Embodiment 1

[0022] This embodiment is used to illustrate the manufacturing method of the mobile phone glass key provided by the present invention.

[0023] 1. Preparation of the button body:

[0024] The thermoplastic elastomer (Dongguan Jiejia Plastic Co., Ltd.) was cut to obtain a key body of 10 mm×6 mm.

[0025] 2. Preparation of patterned glass layer:

[0026] Cut the glass material (Hangzhou Yuguang Special Glass Co., Ltd., colored glass) to obtain a glass layer with the same size as the key body. The resulting glass layer is then polished to obtain a glass layer with an acceptable surface.

[0027] The glass layer with a qualified surface is subjected to tempering treatment. The conditions of the tempering treatment are a preheating temperature of 300° C. and a preheating time of 2 hours; a tempering temperature of 400° C. and a tempering time of 6 hours to obtain a qualified glass layer.

[0028] Print the pattern on the qualified glass layer by screen printing. The specific ste...

Abstract

A mobile phone glass press-key manufacturing process includes: heating a glass layer for 5-20 minutes at the temperature of 40-100 DEG C, and then adhering a keystoke body and the glass layer with patterns through adhesive. Because the manufacturing method provided by the invention heating the glass layer before adhering the keystoke body and the glass layer, water, organics, powder dust and the like substance absorbed at eth surface of the glass layer are removed, and the intrinsic surface energy of the glass layer is recovered, accordingly reinforcing the drawing force between the keystoke body and the glass layer, so that the joint between the keystoke body and the glass layer is firm enough to reach the test requirement.

Description

technical field [0001] The invention relates to a method for manufacturing a mobile phone glass key. Background technique [0002] The mobile phone button is a part on the mobile phone for function control operation. Mobile phone buttons are usually made of materials such as silica gel and glass. The mobile phone keys made of transparent glass materials have good texture, high refractive index, and good decorative effect. However, due to the poor wear resistance of the characters or symbols formed by printing on the surface of the glass, the current mobile phone keys often use the key body +The structure of the glass layer, the characters are printed on the back of the glass layer, so that the obtained keys not only have a good decorative effect, but also make the keys have excellent wear resistance. [0003] In the prior art, the manufacturing method of the button body+glass layer structure is to directly bond the button body+glass materials together with an adhesive. ...
