蓄光涂料发光亮度与余晖时间性能的研究

Study on luminous brightness and afterglow time performance of light storage coatings

自发光材料具备无需其他能源供应在黑暗中自发光的性质。蓄光涂料是自发光材料的一种,不仅有装饰和保护作用,还能储存光和发出可见光。蓄光涂料的发光亮度和余晖时间与自然气候有密切关联,在自然气候中暴露一段时间后均有一定的下降。本文以耐人工气候老化试验、耐沾污试验探究老化时长及物理沾污对蓄光涂料发光亮度和余晖时间的影响。

Self-luminous materials can emit light in the dark without other energy supply.Light storage coating is a kind of self-luminous materials,which not only has the functions of decoration and protection,but also has the function to store light and emit visible light.The luminous brightness and afterglow time of light storage coatings are closely related to the natural climate,and usually decrease after being exposed to the natural climate for a period of time.In this paper,the effects of aging time and physical stain on the luminous brightness and afterglow time of light storage coatings are studied by artificial climate aging and stain resistance tests.
