Owing to the novel insensitive high-energy-density material 2,4,6-triamino-5-nitropyrimidine-1,3-dioxide (ICM-102) has lower sensitivity and higher energy(see in Table S1, Supporting Information), it has great advantages in the application of low-vulnerability propellants. In this paper, the evaluation of ICM-102-containing composite propellants has been carried out, where the decomposition and combustion performances of these propellants have been comprehensively investigated. It has been shown that the main exothermic decomposition peak temperature can be increased from 235 ºC to 350 ºC, when 6 to 10 wt% of ICM-102 was used to replace RDX, but heat release rate was largely increased. Moreover, the burning rate of ICM-102 containing propellants at 3 MPa is in the range of 6.97–7.75 mm•s − 1, depending on its content. The pressure exponent (0.5–3 MPa) is between 0.34–0.44. Compared with the typical propellants with RDX, the burn rate and the flame temperature of ICM-102- containing propellants are higher. In addition, the particle size distributions of condensed combustion products of ICM-102 propellants are narrower and smaller than that of RDX-based one. It also shows that extra products such as aluminum carbide (Al20C) and aluminum oxide nitride (Al5O6N) were produced once ICM-102 was used.

由于新型不敏感的高能量密度材料 2,4,6-triamino-5-nitropyrimidine-1,3-dioxide (ICM-102) 具有较低的灵敏度和较高的能量（见表 S1，支持信息），它在低易损推进剂的应用方面具有很大的优势。本文对含ICM-102的复合推进剂进行了评价，综合研究了这些推进剂的分解和燃烧性能。研究表明，当使用 6 至 10 wt% 的 ICM-102 代替 RDX 时，主要放热分解峰温度可以从 235 ºC 提高到 350 ºC，但放热率大大提高。此外，含推进剂的ICM-102在3 MPa下的燃烧速率在6.97-7.75 mm• s范围内 − 1，取决于其内容。压力指数 (0.5–3 MPa) 在 0.34–0.44 之间。与含RDX的典型推进剂相比，含ICM-102的推进剂的燃烧速度和火焰温度更高。此外，ICM-102 推进剂的冷凝燃烧产物的粒度分布比基于 RDX 的推进剂更窄、更小。它还表明，一旦使用 ICM-102，就会产生额外的产品，例如碳化铝 (Al20C) 和氮氧化铝 (Al5O6N)。
