Description

technical field [0001] The invention relates to a multifunctional smokeless, sulfur-free and moisture-proof agent for firecrackers and a preparation method thereof, belonging to the field of environment-friendly pyrotechnics. Background technique [0002] Every major holiday in our country, many places will use fireworks to celebrate. The most feared thing about setting off fireworks is duds. The dilution of charcoal and potassium nitrate in gunpowder increases, causing difficulty in ignition and slowing down of burning speed; failure of ignition components, blind fire, etc. It will also cause the propellant to absorb too much water, resulting in unqualified ballistic performance of the propellant. [0003] Therefore, the most effective way to improve the moisture-proof problem during the storage of fireworks is to add a moisture-proof agent. At present, the general moisture-proof agents for fireworks on the market, whether they are non-energetic moisture-proof agents such...
