specific Embodiment

[0059] In Table 1, Table 2 and Table 3, commonly used glass raw materials such as oxides and carbonates, etc. were appropriately selected to have the compositions shown in the tables, and were weighed to obtain 150 g of the batch mixture; The batch mixture was placed in a platinum crucible, and the platinum crucible was placed in a silicon-molybdenum furnace, heated to 1650 °C, melted for 3 hours, homogenized and cast into a mold, kept at 620 °C for 1 hour annealing, and then followed by annealing. Furnace cooling to obtain block glass; the block glass is processed to obtain several pieces of thin glass with a size of 50mm×50mm×0.7mm, and the upper and lower surfaces are polished.

[0060] like figure 2 and image 3 As shown, the above-mentioned glass sample 20 is irradiated twice by a metal halide lamp, and the irradiation time is 5s each time, and the filter 10 is used to cover half of the glass sample 20 during irradiation, and the energy in the direct irradiation area fo...

Abstract

The invention discloses a glass suitable for UV curing process and a preparation method thereof. Calculated by mass percentage, the glass includes the following components: 58% to 66% SiO 2 , 15% to 20% Al 2 O 3 , 3% to 8% Li 2 O, 7% to 12% Na 2 O, 0% to 2% K 2 O, 0% to 3% MgO, 0% to 3% B 2 O 3 , 1%~5% ZrO 2 , 0.01~0.05% CeO 2 and 0.01%~2% SnO 2 . The glass provided by the present invention has strong anti-irradiation ability. In the UV curing process of the glass, even if the single irradiation energy is increased, discoloration is not easy to occur, and the transmittance is basically not reduced, so that the number of irradiation can be reduced, and the Production efficiency; and adding a filter device to the glass in the UV curing process has less effect on the color difference of the glass after multiple irradiations.

Description

technical field [0001] The invention relates to the technical field of glass manufacturing, in particular to a glass suitable for a UV curing process and a preparation method thereof. Background technique [0002] At present, most of the glass cover plates on the market are fully laminating process. Compared with the traditional frame attaching process, the fully laminating process has the advantages of better display effect, thinner body and simpler assembly process. Therefore, the fully laminating process has become a screen sticker. The mainstream of lamination, and a very important process in the full lamination process is UV curing, which needs to go through 3000-5000mj / cm 2 The energy is used to irradiate 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. The more serious the yellowing of the glass is. [0003] In order to solve th...
