摘要: 随着光伏产业的高速发展,与之配套使用的减反射玻璃重新进入了研究者们的视野。本文采用湿化学二步刻蚀法制备了具有减反射性能的Na2O-CaO-SiO2平板玻璃,采用分光光度计、扫描电子显微镜、原子力显微镜和X射线能谱仪等测试样品的透过率、表面形貌和断面膜层厚度、表面化学成分、耐酸性和硬度,研究了反应温度和反应时间、玻璃膜层结构与透过率的关系。通过使用弱碱性的混合盐溶液对Na2O-CaO-SiO2玻璃表面进行化学刻蚀,使玻璃表面Si—O键断裂,在玻璃表面形成纳米膜层结构,当膜层厚度达到一定厚度时,一定波长的光在玻璃表面发生相消干涉,透过率最高可达到97.8%,刻蚀前后玻璃成分基本无变化,铅笔硬度达到3H。

Abstract: With the rapid development of photovoltaic industry in recent years, anti-reflective glass comes into researchers' sight. This article uses two-step chemical etching method to prepare Na2O-CaO-SiO2 flat glass with anti-reflective properties. The transmittance, surface morphology, cross-section film thickness, surface chemical composition, acid resistance and hardness of samples were measured by spectrophotometer, scanning electron microscope, atomic force microscope and X-ray energy spectrometer. The relationship between reaction temperature, reaction time, glass film structure and transmittance were studied. The Si—O bonds on Na2O-CaO-SiO2 flat glass surface were broken by etching glass surface with weakly alkaline mixed salt solution, and a nano film structure is formed on the surface of glass. When the corrosion reaches a certain thickness, destructive interference of a certain wavelength of light occurs on glass surface, with a maximum transmittance of 97.8%. The glass composition remains basically unchanged before and after etching, and the pencil hardness reaches 3H.

Key words: anti-reflection glass, transmittance, Na2O-CaO-SiO2 flat glass, wet chemical two-step etching method, surface micro-crack, crack extension
