Summary:The invention provides propellant powder and a preparation method. The propellant powder comprises 30-50 parts of potassium permanganate, 8-20 parts of a binding agent, 10-20 parts of potassium hydrogen phthalate and 20-40 parts of a combustible agent, wherein the combustible agent is a mixture of nitrocotton and charcoal powder. The propellant powder has low friction sensitivity and impact sensitivity, low moisture absorption rate and strong thrust and meanwhile reduces the environmental pollution. 本发明提供了种发射药及制备方法，该发射药由以下组分组成：高锰酸钾30-50份、粘合剂8-20份、邻苯二甲酸氢钾10-20份及可燃剂20-40份；其中，所述可燃剂为硝化棉与木炭粉的混合物。该发射药摩擦感度和撞击感度低、吸湿率小、推力强同时降低了对环境的污染。
