Embodiment 1
[0040] In this example, glasses having various compositions were produced, and the softening point and moisture resistance of the glasses were investigated.
[0041] (making of glass)
[0042] Glasses (SPL-01 to 25) having the compositions shown in Table 1 were produced. The compositions in the table are represented by mass ratios in terms of oxides of the respective components. As a starting material, oxide powder (purity: 99.9%) manufactured by Kosan Chemical Laboratory Co., Ltd. was used. In some samples, Ba(PO 3 ) 2 (barium phosphate, manufactured by Lasa Kogyo Co., Ltd.).
[0043] Each starting material powder was mixed according to the mass ratio shown in Table 1, and put into a platinum crucible. Ag in raw material 2 When the ratio of O is 40% by mass or more, an alumina crucible is used. When mixing, consider avoiding excessive moisture absorption of the raw material powder, and use a metal pharmaceutical spoon to mix in the crucible.
[0044] The crucible cont...
Embodiment 2
[0050] Using the glass obtained in Example 1, a laminate was produced in the following procedure. From the glass prepared in Example 1, SPL-15 having the lowest softening point was pulverized to an average particle size of 0.5 μm or less, and then a resin binder and a solvent were mixed to prepare a slurry for nebulizer spraying. Nitrocellulose was used as the resin binder, and diethylene glycol monobutyl ether acetate was used as the solvent.
[0051] figure 2 An image of a process of forming an oxide layer on a polyimide film is shown. Spray the slurry obtained above with a sprayer 3 on a polyimide film 1 with a thickness of 12 μm to form a film, heat it in a furnace to 250° C. and keep it for 10 minutes and then cool it naturally to form an oxide layer on the polyimide film 1. Object glass layer 2. The oxide glass layer 2 has a thickness of 1.2 μm.
[0052] As a comparative example, a PET film and 50nm SiO2 were deposited on the PET film by vacuum evaporation. X film ...
Embodiment 3
[0062] An organic EL element having a simple structure was produced using the laminate produced in Example 2. Figure 4 A part of the organic EL element used in this experiment is shown. On a glass substrate 4, a metal cathode 5 / organic EL layer 6 (green) / ITO electrode layer 7 are laminated. In a glove box under an atmospheric pressure (0.1 MPa) nitrogen atmosphere, the laminated body 8 of the present invention cut into a size of 40 mm × 50 mm is pasted with an adhesive on the ITO electrode of an organic EL element (15 mm × 20 mm) and sealed. The organic EL element is referred to as EL element A. Similarly, the organic EL elements sealed with the films of Comparative Examples 1 and 2 in Table 2 were designated as EL elements B and C.
[0063] These organic EL elements were placed in humid air with an air temperature of 50° C. and a relative humidity of 90%, connected to an AC power supply of 100 V and 400 Hz, and continuously lit to measure their luminance. Assuming that th...
