Safe and environmentally-friendly firework propellant powder

The invention discloses a safe and environmentally-friendly firework propellant powder. The propellant powder comprises, by weight, 5-60 parts of a smokeless oxidant which is a novel high-energy insensitive material N-guanylurea dinitramide, 5-80 parts of a smokeless reducing agent which is a mixture containing any two or more of diazidoazoxyfurazan, 4,4'-bis(4-nitro-3-azoxyfurazyl)azoxyfurazan, cyclobisazotetrafurazan, lanthanum phthalate, 3,6-bis(azido)-1,2,4,5-tetrapiperazine, dinitroazodifurazan, modified nitroguanidine and potassium dichromate, and 2-10 parts of a smokeless adhesive which is carboxymethyl cellulose. The propellant powder has the advantages of realization of no smoke, no toxicity, no smell and no dust pollution in the set-off process, good moisture resistance, stable medical property, convenience in storage and transportation, and simplicity in processing and preparation. 本发明公开了种安全环保烟花发射药。特点是，所述发射药由无烟氧化剂、无烟还原剂、无烟粘合剂组成，其组份及重量份数比为：无烟氧化剂：是指新型高能钝感材料N-脒基脲二硝酰胺，用量为5-60重量份；无烟还原剂：为二叠氮基偶氮氧化呋咱、4,4'-
