[0047] In a second aspect, the present invention provides a method for preparing glass, the method comprising: sequentially mixing, melting, homogenizing, shaping and annealing the above composition for glass.

[0048] According to the method of the present invention, the melting conditions include: the temperature is 1450-1580° C., and the time is 4-10 hours. Those skilled in the art can determine the specific melting temperature and melting time according to the actual situation, which are well known to those skilled in the art, and will not be repeated here.

[0049] According to the method of the present invention, the homogenization is a conventional homogenization method in the art, for example, the gas bubbles in the molten glass can escape by stirring and the components in the molten glass are evenly distributed.

[0050] According to the method of the present invention, the forming is a conventional forming method in the field, for example, it can be carried out in a ...

[0068] Weigh each component as shown in Tables 1 and 2, mix well, pour the mixture into a platinum-rhodium crucible, then heat in a resistance furnace at 1500°C for 6 hours, and stir with a platinum rod to remove air bubbles. The molten glass is poured into a stainless steel cast iron mold to form a specified block glass product, and then the glass product is annealed in an annealing furnace at 600°C for 2 hours, then the power is turned off and the furnace is cooled to 25°C. The glass product is cut, ground and polished, then cleaned with deionized water and dried to obtain a finished glass product, which is chemically tempered before testing. Various properties of each glass product were measured respectively, and the results are shown in Tables 1 and 2.

Abstract

The invention relates to the field of glass production and particularly relates to a glass composition and glass and a preparation method and application thereof. The glass composition contains SiO2, Al2O3, B2O3, Fe2O3, ZrO2, ZnO, alkali metal oxide, alkaline earth metal oxide and rare-earth metal oxide. The invention also discloses glass and a preparation method and application thereof. In the invention, the prepared glass has excellent mechanical properties such as relatively high strain point, softening point and hardness; and the tempering effect of the prepared glass is relatively good. Therefore, the prepared glass with special properties is relatively applicable to touch screen cover plates of a float process.

Description

technical field [0001] The invention relates to the field of glass manufacturing, in particular to a composition for glass, glass and a preparation method and application thereof. Background technique [0002] At present, the touch screen (Touch panel) has become an indispensable part of our life. Various terminals such as LCD TVs, smart phones, tablet computers, and ATM machines used by people basically rely on touch operations. The touch screen is made of cover glass. , OCA photoresist, conductive silver paste / ITO conductive film and substrate. The three major development trends of touch screens in the future are large screen, ultra-thin and ultra-high transparency. However, for the protective cover glass, it is a technical problem to have ultra-thinness and high strength at the same time. Chemical tempering technology is a common technology for tempering ultra-thin glass with a thickness of less than 1mm. The small ions in the glass components are replaced by the large i...
