标志反光膜逆反射性能评价方法与影响因素分析

Evaluation method of retroreflective performance of sign reflective and analysis of influencing factors

夜间交通标志反光主要靠反光膜的逆反射性能实现,逆反射系数是逆反射性能最重要的指标。从逆反射系数的概念、要求、测定方法、影响因素等方面入手进行分析,重点论述了最低逆反射系数的要求、逆反射性能的评价方法,以及影响逆反射性能因素。

The reflection of the night traffic sign is mainly achieved by the retroreflective performance of the reflective film,and the retroreflection coefficient is the most important indicator of the retroreflective performance.From the aspects of the concept,requirements,measurement methods and influencing factors of the retroreflection coefficient,the paper analyzes the requirements of the minimum retroreflection coefficient,the evaluation method of retroreflective performance,and the factors affecting the retroreflective performance.
