Abstract

A manufacturing method of ultrathin antiglare electronic touch screen glass comprises: step I, cleaning glass; step II, treating the cleaned glass in antiglare liquid for 150-240 seconds; step III, cooling; step IV, spray-cleaning and drying at a constant temperature; step V, chemically tempering the glass by soaking in molten potassium nitrate solution; and step VI, air-cooling. The invention has the following advantages of: 1. low manufacturing cost and simple processing, 2. manufacturing glass with a thickness smaller than 0.7 mm, a good antiglare effect, a visible light transmittance higher than 85%, a visible light reflectance smaller than 4%, high bending strength, impact strength and temperature difference resistance, and pressure resistance up to 200-550 MPa, 3. realizing the purposes of ultralow acid, low discharge and easy water quality treatment, with the discharged water index reaching the national industrial sewage discharge standard to cause no pollution to the environment, and 4. having wide application.

Description

Technical field: [0001] The invention relates to a method for manufacturing glass, in particular to a method for manufacturing ultra-thin anti-glare electronic touch screen glass. Background technique: [0002] At present, the electronic touch screen glass sold in the domestic market is generally realized by coating the glass surface. The anti-glare effect of this kind of coated anti-glare glass is better, but the production cost is high, and the coating film is easy to fall off, and the surface is easy to leave scratches, etc., which affects the transparency, and the produced glass has rough surface particles, and its bending strength, The impact strength and temperature difference resistance are poor. In addition, this production process cannot produce electronic touch screen glass with a thickness of less than 0.7mm. Invention content: [0003] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art, and to provide a metho...
