摘要: 高温熔体特性不仅影响有机发光二极管(OLED)基板玻璃的熔化与制备,还影响OLED器件的性能和使用寿命。本文以无碱铝硼硅酸盐玻璃作为OLED基板玻璃研究对象,系统探究SrO/MgO摩尔比对OLED基板玻璃高温熔体特性(高温黏度、高温电阻率、表面张力)的影响。结果表明:随着SrO/MgO摩尔比增大,玻璃熔体高温黏度呈非线性变化,在SrO/MgO摩尔比为3.31时,高温黏度达到极大值;1 600 ℃下,熔体高温电阻率平均提高32.22%,熔体表面张力平均下降2.47%。本研究为优化OLED基板玻璃的关键工艺性能提供了科学依据,对工业化生产制造具有重要指导意义。

Abstract: The properties of high-temperature melts not only affect the melting and preparation of organic light-emitting diode (OLED)substrate glass but also influence the performance and service life of OLED devices. In this paper, alkali-free aluminoborosilicate glass was taken as the research object, and the influence of SrO/MgO molar ratio on the properties of high-temperature melts of OLED substrate glass (high-temperature viscosity, high-temperature resistivity, and surface tension) was systematically explored. The results show that with the increase of the SrO/MgO molar ratio, the high-temperature viscosity of the glass melt shows a nonlinear change, and when the SrO/MgO molar ratio is 3.31, the high-temperature viscosity reaches a maximum value. The high-temperature resistivity of the melt at 1 600 ℃ is increased by an average of 32.22%, and the melt surface tension decreases by an average of 2.47%. This study provides a scientific basis for optimizing key process performance of OLED substrate glass and has important guiding significance for industrial production and manufacturing.
