摘要: 为充气靶丸的精密装配提供有效的胶斑定位检测方法,研究了具有荧光特性的环氧胶黏剂,通过环氧胶黏剂与香豆素和JS-064荧光染料的相容性及荧光性的研究,探索其适用于靶丸装配和检测的添加工艺。分别测定了入射波长和适用于工艺的激发波长,研究了荧光强度与香豆素浓度的关系以及固化剂对荧光强度的影响。并确定了无水乙醇减小表面张力的工艺方法。结果表明:香豆素的激发波长为274 nm,入射波长为519 nm;荧光染料的激发波长为435 nm,适用于胶斑定位检测的激发波长为365 nm;香豆素能很好地溶于固化剂176中,有淡蓝色荧光,而荧光染料均匀分散于胶黏体系,且荧光性能良好。Abstract: In order to provide spot positioning detection method of adhesive glue for precision assembly of pneumatic pellet, this paper studies the compatibility and fluorescence of epoxy adhesive with coumarin and fluorescent dye. The adding process is introduced, the impacts of coumarin concentration as well as the curing agent on the fluorescence intensity are studied, and anhydrous ethanol is used to reduce the surface tension. The results show that the incident wavelength of coumarin and fluorescent dye is 274 nm and 435 nm, the excitation wavelength is 519 nm and 365 nm, respectively. Coumarin can be dissolved in the curing agent 176 well and blue fluorescence light is observed. The fluorescent dye is uniformly dispersed in the adhesive system, which can be used for detecting and locating.
