Abstract :

In this research, in order to coating pentaerythritol tetranitrate (PETN) particles, estane compound and nano-pigment of red Lithol rubine B 57:1 (NLR) were used. After structural studies of nanocomposite by infrared (FT-IR) and field emission scanning electron microscopy (FESEM), Taguchi statistical design method was used to investigation and optimization of optical reflectance of nano-composite at 532 nm. The effect of four factors of estane concentration, NLR concentration, stirring speed and ultrasonic bath temperature in three levels on optical reflection was investigated and analysis of variance (ANOVA) showed that NLR concentration with the participation of 79.36 percent had highest effect. Optimal conditions to achieve a minimum light reflectance were obtained of estane 5 wt%, NLR 7 wt%, stirring speed 400 rpm and ultrasonic bath temperature of 50°C. The lowest light reflectance by analyzing the data variance for optimum conditions was estimated 4.97 ± 1.67. The mean experimental result for optical reflectance of the synthesized nano-composite under optimum conditions was 5.90 percent. Follows, thermal behavior and vacuum stability of the optimal sample was investigated that the results show that the melting point temperature and decomposition of nano-composite are not different compared to the pure PETN Indicating the compatibility of NLR and estane with PETN.
