High-pressure-index and low-combustion-temperature fuel gas generating agent and preparation method thereof

The invention relates to a high-pressure-index and low-combustion-temperature fuel gas generating agent and a preparation method thereof. The fuel gas generating agent with the pressure index larger than or equal to 0.60 and the combustion temperature smaller than or equal to 1200 DEG C is obtained through selection of all components and adjustment of the proportion, especially through cooperation of a main oxidizing agent and a performance adjusting agent and adjustment of the proportion of a combustion temperature adjusting agent. Meanwhile, the fuel gas generating agent has the advantages of being free of metal powder, low in residue and easy to adjust in performance, can be used for a fuel gas generator with adjustable thrust, and greatly improves the maneuverability and penetration ability of guided missiles. 本发明涉及一种高压强指数低燃温燃气发生剂及其制备方法，通过对各组分的选取及对配比的调整，特别是通过主氧化剂与性能调节剂的配合，以及对燃温调节剂配比的调整，得到一种压强指数≥0.60，燃温≤1200℃的燃气发生剂，同时本发明燃气发生器还具有不含金属粉、低残渣和性能易于调节的优点，可用于推力可调的燃气发生器，大幅提高导弹的机动性和突防能力。
