Abstract

The invention belongs to the technical field of phone protective films, and particularly relates to a preparation method of a curved screen phone tempered glass film. The preparation method comprises the following steps: attaching an OCA optical adhesive with a specific thickness to the upper surface of a TPU (thermoplastic polyurethane) substrate, attaching a silica gel with a specific thickness to the lower surface of the TPU substrate to obtain a TPU film, and attaching the TPU film to a glass film subjected to hot bending tempering treatment. The curved screen phone tempered glass film has the advantages of favorable hardness, favorable water resistance and favorable high-temperature resistance, and can achieve favorable effects of impact resistance, scratch resistance, wear resistance and drop prevention. The curved screen phone tempered glass film can be completely attached to the phone curved screen without the phenomena of bubbles, degumming, press marks and the like, can effectively enhance the aesthetic property of the phone, can not influence the sensitivity of the phone screen after being attached to the phone curved screen, and is an ideal curved screen phone tempered glass film.

Description

technical field [0001] The invention belongs to the technical field of mobile phone protective films, and in particular relates to a preparation method of a curved screen mobile phone tempered glass film. Background technique [0002] With the development and progress of science and technology, mobile phones have become an indispensable tool in people's daily work and life. Existing smart phones are basically capacitive touch screen mobile phones. Capacitive touch screens work by using human body induced current. When the finger touches the surface of the touch screen, under the electric field of the human body, the conductive circuit inside the mobile phone touch screen forms a coupling capacitance with the user's finger. The capacitor is a direct conductor under high-frequency current, and the finger will absorb the weak current from the contact position; the current flows out through the electrodes on the four corners of the touch screen, and the current of each electrode...
