A kind of anti-blue light high-strength aluminosilicate glass and preparation method thereof

Abstract

The invention relates to an anti-blue light high-strength aluminosilicate glass and a preparation method thereof, which is characterized in that: SiO 2 : 58~65%, Al 2 o 3 : 15~25%, ZnO: 0.1~5%, MgO: 1%~10%, CaO: 1~5%, B 2 o 3 : 0~6%, K 2 O: 2~10%, Na 2 O: 5~12%, Li 2 O: 1~9%, CdS: 0.01~3%, CdSe: 0.01~3%, reducing agent: 0.01~2%, SnO 2 : 0.5~2; 1. Mix cadmium sulfide, cadmium selenide and zinc oxide, put them in an electric furnace, react at 360~450°C for 0.5~1.5h and then cool; 2. Mix the remaining raw materials with the result of step 1, and grind them evenly to match 3. Heat up the electric furnace to 800~1100°C, preheat the batch material for 1~5min, put it into the furnace, raise the temperature to 1580~1650°C and keep it for 2~4h; 4. Cast it in a mold on a copper plate and anneal it; 5. .Heat to 500~650℃ for 1~4h, then cool. The advantages of the present invention are: after melting and annealing, the chemical toughening method is used for strengthening treatment, and the prepared glass has high strength, anti-blue light effect, high visible light transmittance, etc.; it is suitable for use as electronic display screen cover glass and screen protection glass.

Description

technical field [0001] The invention relates to the field of electronic glass, in particular to an anti-blue light high-strength aluminosilicate glass and a preparation method thereof. Background technique [0002] With the popularity of mobile devices such as smartphones around the world, consumers spend significantly more time viewing information displays (mobile phones, tablet computers, ATM machines, LCD monitors, and laptops, etc.), and some Internet users will experience vision loss, cataracts, or blindness, etc. Eye diseases of varying degrees. An important reason for this is the damage of blue light to the eyes. Using blue light chips to excite yellow light phosphors is the most commonly used white light synthesis method, and this white light usually has a higher color temperature and is called "cold light". When facing various backlight displays such as smartphones or computers for a long time, the eyes will be damaged by blue light radiation. When blue light and...
