and S3, annealing the glass sheet.
In the embodiment, the preparation of the ultrathin glass mainly comprises three steps of preheating, heating and forming and annealing, the thickness selection range of the glass sheet is 4-6 mm, and the glass sheet can be selected from soda-lime-silica glass, high-alkali aluminosilicate glass, borosilicate glass, alkali-free aluminoborosilicate glass and the like. The main purpose of step S1 is to preheat the glass sheet in advance to prevent the glass from cracking during the thinning process. The heating is the core area for the forming of the ultrathin flexible glass, and the structure of the heating area and the heating temperature directly determine the forming quality of the ultrathin flexible glass. The temperature fields with three different temperatures are arranged, so that different regions of the original glass sheet are heated differently, the width of the wedge-shaped part at the edge can be reduced while the heating, extending and thinning are guaranteed, and the availability of the ultrathin glass is improved. The total width of the three temperature fields is larger than the width of the glass sheet, so that the edge of the glass sheet can be heated. The annealing area is mainly used for annealing the formed ultrathin flexible glass, so that the internal stress of the glass is reduced.
The shrinkage rate of the ultrathin flexible glass prepared by the invention is controlled below 15%, the width of the wedge-shaped edge part is less than or equal to 20mm, and the yield of the glass is greatly improved.
Further, the number of the first temperature fields 12 is one, two second temperature fields 13 and two third temperature fields 14 are arranged, the two second temperature fields 13 are located on two symmetrical sides of the first temperature field 12, and the third temperature fields 14 are located on one sides, far away from the first temperature field 12, of the second temperature fields 13.
In this embodiment, the middle is a first temperature field 12, and a second temperature field 13 and a third temperature field 14 are sequentially disposed on both sides of the first temperature field 12. The glass original sheet can be symmetrically heated, so that the change rates of the two edges in the width direction of the glass are consistent.
Further, the width L1 of the first temperature field 12 is 40mm-60mm smaller than the width of the glass original sheet, and the width L2 of the second temperature field 13 is in the range of: l2 is more than or equal to 10mm and less than or equal to 20mm, and the width L3 of the third temperature field 14 is more than or equal to 20mm and less than or equal to L3 and less than or equal to 40 mm.
In this embodiment, the width scope of different temperature fields is different, can carry out the heating of different degrees to the former piece of glass according to the position of locating and the temperature of this position to the deformation of the former piece of glass of control different temperature fields makes the tensile back of glass can accord with ultra-thin glass's thickness requirement, can make the marginal shrinkage rate less again.
Further, the temperature difference in the region of the first temperature field 12 is 0-5 ℃.
In the embodiment, the temperature difference of the first temperature field 12 on the same horizontal line is less than or equal to 5 ℃, so that the consistency of viscosity in the thinning process of the glass original sheet is fully ensured.
Further, the temperature of the first temperature field 12 is such that the glass viscosity is between 10 6.6 Pa·S～10 4 The characteristic temperature corresponding to Pa.S, the temperature of the second temperature field 13 is 10-20 ℃ higher than that of the first temperature field 12, and the temperature of the third temperature field 14 is at least 150 ℃ lower than that of the first temperature field 12.
In this embodiment, the temperature magnitudes corresponding to the three temperature fields are as follows: the third temperature field 14 < the first temperature field 12 < the second temperature field 13, the third temperature field 14 is lower than the first temperature field 12 by more than 150 ℃, and the edge of the glass sheet can be rapidly fixed and prevented from shrinking inwards. The second temperature field 13 is 10-20 c higher than the first temperature field 12, which effectively prevents the wedge-shaped edge from expanding inward, so that the wedge-shaped edge forms a good boundary with the active area of the glass sheet.
Furthermore, the total width of the three temperature fields of the first temperature field 12, the second temperature field 13 and the third temperature field 14 is 10mm-30mm larger than the width of the glass original sheet.

When the width of the edge of the glass is too small, the drawn glass is easy to shrink; when the width of the edge of the glass base sheet is too large, the melting of the edge of the glass is not good.
Furthermore, the feeding speed of the glass sheet is 0.3 mm/s-1 mm/s, and the drawing discharging speed is 20 mm/s-100 mm/s.
In the embodiment, the traction discharging speed is higher than the feeding speed, and the extension thinning can be realized after the heating. Meanwhile, the glass can be prevented from breaking due to too much traction discharging speed exceeding the feeding speed.
Further, the annealing temperature in step S3 is lower than the glass viscosity of 10 12.4 Characteristic temperature corresponding to Pa · S.
In the embodiment, the shaping of the glass is affected due to the excessively high annealing temperature, and the glass is softened and deformed, so that the thickness of the glass is increased; below the lower annealing temperature limit, the glass structure is fixed and the internal particles cannot move and stress cannot be dispersed or eliminated.
