Problems solved by technology

The hydrogel film has the advantages of ultra-thin, anti-fingerprint, strong self-healing ability, and strong adaptability to curved screens. At the same time, it also has disadvantages such as poor impact resistance, poor light transmission, and poor hand feeling.
The tempered film is made of a layer of plexiglass, which has the advantages of high hardness, scratch resistance, good light transmittance, and strong impact resistance. At present, users tend to use thinner tempered films, but the structure of thinner tempered films The strength is small, it is difficult to meet the needs of protecting the screen of the mobile phone

Embodiment 1

[0041] A method for preparing a tempered film, comprising the steps of:

[0042] S1. Use a cutting machine to cut the glass substrate: before cutting, use clean white paper to pad the cutting platform of the cutting machine, and place the glass substrate on the white paper to avoid the glass substrate during the cutting process. The impurities on the cutting machine are attached in the middle, and then the glass substrate is cut into the required shape and size by the cutting machine to obtain the glass substrate. The thickness range of the glass substrate is 0.15mm.

[0043] S2. CNC engraving: CNC machine tools are used to carve holes corresponding to the model on the glass substrate after cutting.

[0044] S3. Light sweeping: polish the edge of the glass substrate to make it into a certain arc, and the light sweeping time is 4 minutes.

[0045] S4. Ultrasonic cleaning: In the dust-free workshop, put the glass substrate in an ultrasonic cleaning machine for three cleanings, ...

Embodiment 2

[0056] A kind of preparation method of toughened film, the difference with embodiment 1 is: comprise the following steps:

[0057] S1. Use a cutting machine to cut the glass substrate: before cutting, use clean white paper to pad the cutting platform of the cutting machine, and place the glass substrate on the white paper to avoid the glass substrate during the cutting process. The impurities on the cutting machine are attached in the middle, and then the glass substrate is cut into the required shape and size by the cutting machine to obtain the glass substrate. The thickness of the glass substrate is 0.2mm.

[0058] S2. CNC engraving: CNC machine tools are used to carve holes corresponding to the model on the glass substrate after cutting.

[0059] S3. Light sweeping: polish the edge of the glass substrate to make it into a certain arc, and the light sweeping time is 5 minutes.

[0060] S4. Ultrasonic cleaning: In the dust-free workshop, put the glass substrate in an ultras...

Embodiment 3

[0071] A kind of preparation method of toughened film, the difference with embodiment 1 is: comprise the following steps:

[0072] S1. Use a cutting machine to cut the glass substrate: before cutting, use clean white paper to pad the cutting platform of the cutting machine, and place the glass substrate on the white paper to avoid the glass substrate during the cutting process. The impurities on the cutting machine are attached in the middle, and then the glass substrate is cut into the required shape and size by the cutting machine to obtain the glass substrate. The thickness of the glass substrate is 0.22mm.

[0073] S2. CNC engraving: CNC machine tools are used to carve holes corresponding to the model on the glass substrate after cutting.

[0074] S3. Light sweeping: polish the edge of the glass substrate to make it into a certain arc, and the sweeping time is 6 minutes.

[0075] S4. Ultrasonic cleaning: In the dust-free workshop, put the glass substrate in an ultrasonic ...

Abstract

The invention relates to the field of preparation processes for tempered films, in particular to a tempered film and a preparation method thereof. The preparation method includes the following steps:S1, rough shape cutting; S2, CNC fine carving; S3, thorough sweeping; S4, ultrasonic cleaning; S5, tempering; S6, coating of anti-fingerprint oil; S7, drying; and S8, bonding via AB glue. The temperedfilm has the beneficial effects that the thin tempered film has better structural strength, and can meet both the requirement for protecting the structural strength of a mobile phone screen and the use requirement of a user.

Description

technical field [0001] The invention relates to the technical field of tempered film preparation technology, more specifically, it relates to a tempered film and a preparation method thereof. Background technique [0002] In recent years, a series of smart digital products such as mobile phones have sprung up. While enjoying the unparalleled sensory stimulation brought by them, people also have concerns about the damage of their screens due to improper use or the additional personal safety caused by screen damage. . As a result, screen protectors emerged at the historic moment and developed vigorously, which is in the ascendant. [0003] There are two types of common screen protectors, one is hydrogel film and the other is tempered film. The hydrogel film is a soft film made of a layer of thermoplastic polyurethane elastomer (TPU) or polyethylene terephthalate (PET). The hydrogel film has the advantages of ultra-thin, anti-fingerprint, strong self-healing ability, and str...
