specific Embodiment

[0060] In Table 1, Table 2, and Table 3, commonly used glass raw materials such as oxides and carbonates, etc. are appropriately selected to have the composition shown in the table, and weighed to obtain 150 g of the batch mixture; then, the Put the batch mixture into a platinum crucible, put the platinum crucible into a silicon-molybdenum furnace, raise the temperature to 1650°C, and melt it for 3 hours, homogenize it and cast it into a mold, keep it at 620°C for 1 hour and anneal, then follow Cool the furnace to obtain block glass; process the block glass to obtain several pieces of thin glass with a size of 50mm×50mm×0.7mm and polished upper and lower surfaces.

[0061] like figure 2 and image 3 As shown, metal halide lamps are used to irradiate the glass sample 20 twice, each time for 5 s, half of the glass sample 20 is covered with an optical filter 10 during irradiation, and the energy in the direct area of ​​each irradiation is 2800mj / cm 2 , the total energy of two...

Abstract

The invention discloses glass suitable for a UV curing process and a preparation method thereof. The glass comprises the following components in percentage by mass: 58%-66% of SiO2, 15%-20% of Al2O3,3%-8% of Li2O, 7%-12% of Na2O, 0%-2% of K2O, 0%-3% of MgO, 0%-3% of B2O3, 1%-5% of ZrO2, 0.01%-0.05% of CeO2 and 0.01%-2% of SnO2. The glass provided by the invention has strong anti-irradiation capability, is not easy to discolor even if the single irradiation energy is improved in the UV curing process of the glass, and the transmittance is not reduced basically, so that the irradiation frequency can be reduced, and the production efficiency is improved; and a light filtering device is additionally arranged on the glass in the UV curing process, so that the influence on the color differenceof the glass after multiple times of irradiation is small.

Description

technical field [0001] The invention relates to the technical field of glass manufacturing, in particular to a glass suitable for UV curing technology and a preparation method thereof. Background technique [0002] At present, most of the glass covers on the market are fully laminated. Compared with the traditional frame lamination process, the full lamination process has the advantages of better display effect, thinner body and simpler assembly process. Therefore, the full lamination process has become a screen paste process. The mainstream of bonding, and a very important process in the full bonding process is UV curing, which requires 3000-5000mj / cm 2 The energy irradiates the glass cover; however, the general glass cover will turn yellow after UV curing, and the transmittance will also decrease, which will seriously affect the appearance and display effect, and the higher the UV energy, the more the irradiation times. The yellowing performance of the glass is more serio...
