Embodiment 1

[0028] A preparation method for an antibacterial tempered glass film, comprising the steps of:

[0029] S1, cutting the glass and processing it into multiple rectangular glasses;

[0030] S2, then carry out CNC carving on the rectangular glass, further process it into a shape matching the mobile phone or tablet, and process the generated burrs to obtain the first semi-finished product;

[0031] S3, performing a sweeping treatment on the first semi-finished product, and obtaining a second semi-finished product with a curved edge after cleaning with a water-based industrial cleaning agent WSG-100;

[0032] S4, perform tempering treatment on the second semi-finished product, and obtain the third semi-finished product after cleaning with water-based industrial cleaning agent WSG-100. The process of tempering treatment is: heat the second semi-finished product to 700°C for rapid cooling, the heating time and The time of cooling can be adjusted by those skilled in the art according...

Embodiment 2

[0038] A preparation method for an antibacterial tempered glass film, comprising the steps of:

[0039] S1~S5 are the same as embodiment 1;

[0040] S6, antibacterial oiling treatment: the fourth semi-finished product is first sprayed with nano-silver dispersion (Andimei CAG-12) twice, dried at 90°C for 30 minutes, and then sprayed with anti-fingerprint oil. Add 2wt% organic-inorganic compound antibacterial agent powder (Antimei EVD) to the anti-fingerprint oil, bake at 145°C for 15 minutes, and wash with water-based industrial cleaning agent WSG-130 to obtain the fifth semi-finished product; wherein the anti-fingerprint The fingerprint oil is commercial anti-fingerprint oil FMD-2201;

[0041] S7, attaching AB glue to the fifth semi-finished product, degassing, film inspection, and packaging to obtain an antibacterial tempered glass film product.

Embodiment 3

[0043] A preparation method for an antibacterial tempered glass film, comprising the steps of:

[0044] S1~S5 are the same as embodiment 1;

[0045]S6, antibacterial oiling treatment: the fourth semi-finished product is first sprayed with nano-silver dispersion (Andimei CAG-12) twice, dried at 110°C for 15 minutes, and then sprayed with anti-fingerprint oil. Add 6wt% organic-inorganic compound antibacterial agent powder (Antimei EVD) to the anti-fingerprint oil, bake at 155°C for 30 minutes, and wash with water-based industrial cleaning agent WSG-100 to obtain the fifth semi-finished product; wherein the anti-fingerprint The fingerprint oil is commercial anti-fingerprint oil FMD-2201;

[0046] S7, attaching AB glue to the fifth semi-finished product, degassing, film inspection, and packaging to obtain an antibacterial tempered glass film product.

[0047] For the above examples, use an eraser to wipe the same position for 500 times to test the antibacterial performance to ev...
