Abstract

The invention discloses an ultrathin tempered film and a preparation process thereof. The preparation process comprises the following processes: S1, cutting: cutting a glass substrate into required shapes and sizes by adopting a cutting machine; S2, CNC fine carving: carving a hole site corresponding to the type of an electronic product in the cut glass substrate by a numerical control machine tool; S3, primary ultrasonic cleaning: putting the glass substrate into an ultrasonic cleaning machine, and cleaning; S4, tempering and strengthening: tempering and strengthening the glass substrate through a physical method and a chemical method; S5, AF electric / spray plating: carrying out electric / spray plating of anti-fingerprint oil on the surface of the glass substrate; S6, secondary ultrasoniccleaning: putting the glass substrate into an ultrasonic cleaning machine, and carrying out secondary cleaning; and S7, protective film coating: laminating protective films on two surfaces of the glass substrate, packaging and warehousing. The prepared ultrathin tempered film is light and thinner, has good toughness and shock resistance, and can be safely used for a long time.

Description

technical field [0001] The invention relates to the technical field of tempered film preparation and production, in particular to an ultra-thin tempered film and a preparation process thereof. Background technique [0002] Tempered glass film, also known as tempered glass film, is currently the most enhanced protective film for the screens of mobile phones, tablets and other electronic products. The thickness of this protective film is only 0.1mm, which can completely cover the original screen and prevent it from being damaged by external forces. , Scratch, and increase the flushing absorption, which is 5 times higher than the PET film standard, and does not affect the viewing effect of the screen. However, the current tempered film is often hard and brittle because of its texture, and the overall performance is poor in shock resistance and fragile. [0003] In response to the above problems, the Chinese patent with the patent notification number CN108046597A proposes a sho...
