Problems solved by technology

The production method of tempered glass film on the existing market is usually to use CNC numerical control machine tools to machine the large pieces of glass into small pieces of glass, and then to make them through cleaning, polishing, tempering and other processes in sequence. The hardness value reaches 3-5H. The disadvantage of this traditional processing method is that when CNC machine tools are used for cutting and processing, due to the influence of various factors such as cutting speed, feed time, and stress applied by the tool, the edge of the glass will appear uneven and jagged under the observation of a magnifying glass. , and micro-cracks will appear on the surface. These processing defects cause the hardness of the glass film to reach 5-6H at most. Protecting the screen of the mobile phone cannot meet the needs of actual use

Abstract

The invention relates to a twice reinforced glass membrane and a manufacturing method thereof. The manufacturing method is carried out by the steps of: (1) cutting: cutting a glass blank material into multiple small glass blanks of appropriate size; (2) carving: putting the small glass blanks into a CNC engraving and milling machine and conducting punching and edge polishing; (3) polishing; (4) cleaning; (5) primary reinforcement: completely soaking the glass blanks into an etching solution preloaded with an etching solution for 1-2min to let the etching solution destroy an original silicon oxide film on the glass surface, evenly eroding off surface microcracks and marginal sawtooth microcracks generated by CNC cutting to achieve tip blunting of surface microcracks and smooth edges, and hardness of 7H; (6) secondary reinforcement: putting the cleaned glass blanks into a tempering frame, sending the tempering frame into a preheating furnace and performing heating for 30-60min to 340-380DEG C, then putting the tempering frame into a tempering furnace, conducting heating to 380-420DEG C, and performing tempering for 3-6h to make the hardness reach 9H; (7) plasma spraying of fingerprint oil; (8) laminating; and (9) packaging.

Description

technical field [0001] The invention relates to a double-strength tempered glass film and a manufacturing method thereof. Background technique [0002] Tempered glass film, also known as tempered film, is a protective film attached to the surface of the mobile phone screen film to prevent the screen from breaking when the mobile phone slips. It uses chemical or physical methods to form compressive stress on the glass surface. When the glass is subjected to external forces, it first offsets it. Surface stress, thereby improving the bearing capacity, enhancing the wind pressure resistance, cold and heat resistance and impact resistance of the glass itself, and obtaining excellent properties such as high hardness, low toughness, good wear resistance, and not easy to scratch. The production method of tempered glass film on the existing market is usually to use CNC numerical control machine tools to machine the large pieces of glass into small pieces of glass, and then to make th...
