Problems solved by technology

Although the processing of curved tempered glass and ordinary tempered glass has many similarities in processing, the curved tempered glass is processed by traditional processing methods. Due to the existence of the curved edge of the curved screen mobile phone, it is difficult to process the curved tempered glass after processing. Stable attachment, thus affecting the protective effect of the entire curved tempered film

Abstract

The invention relates to the technical field of screen protection films, in particular to a curved tempered film and a preparation process thereof. The preparation process comprises the following steps: S1, cutting; S2, hot bending; S3, re-strengthening is conducted; S4, ultrasonic cleaning; S5, front surface coating; S6, back surface coating; and S7, double-sided film coating. The preparation process is simple, the previous CNC hole machining steps are reduced; a small substrate is cut through a mold; batch base materials can be formed at a time, the production is convenient and fast, the size is highly uniform, an arc edge treatment is conducted through hot bending, the forming effect is good under the condition that the quality of the base materials is high, the formed arc edge can be well matched wtih the arc edge of a mobile phone screen, dust accumulation and edge warping are avoided, and the overall protection effect of the curved tempered film is improved.

Description

technical field [0001] The invention relates to the technical field of screen protective films, in particular to a curved tempered film and a preparation process thereof. Background technique [0002] With the development of the economy, smart phones and tablet computers have been integrated into people's lives. With the wide application of large-screen smart devices, the emergence of glass tempered film has brought safety to people. Avoid damage to the screen due to force. The accompanying result is often that the tempered film counteracts the external force by rupturing. [0003] As curved screen mobile phones gradually become the mainstream of the mobile phone market, the curved screen tempered film applied to curved screen mobile phones is also gradually occupying the tempered film market. Although the processing of curved tempered glass and ordinary tempered glass has many similarities in processing, the curved tempered glass is processed by traditional processing met...
