Problems solved by technology

[0003] In the current actual production, the firework propellant has been using black powder (military nitrate) composed of potassium nitrate, charcoal and sulfur, which will produce a large amount of black smoke when burning, which will affect the effect of fireworks. A large amount of oxides and residues of carbon, sulfur, and potassium remain, which seriously pollutes the environment. At the same time, during the production of fireworks propellants, the amount of propellant in the barrel is often insufficiently controlled, resulting in large differences in the produced barrels and affecting the quality of fireworks production.

Abstract

The invention discloses a preparation method of a smokeless propellant for fireworks. The smokeless propellant for fireworks is produced by the following steps: S1. Prepare raw materials, including dispersion liquid, guanidine nitrate, nitrodiethylene glycol, nitrocellulose and combustible S2, guanidine nitrate, nitrated diethylene glycol and nitrocellulose are added into the mixer and mixed together to obtain the composite material; S3, the dispersion liquid, the composite material and the flammable agent are mixed and loaded into the autoclave to obtain Fireworks propellant; S4, the firework propellant is loaded into the barrel through the filling device, and then sorted, bundled, packaged, and stored to obtain the firework smokeless propellant; in the present invention, the fireworks smokeless propellant is burned to produce non-hygroscopic propellant It contains no sulfur oxides and nitrogen oxides, and is smokeless after combustion, and the smoke produced by the combustion of the propellant mixture is more than 85% lower than the existing black powder concentration.

Description

technical field [0001] The invention relates to the technical field of propellant, in particular to a method for preparing smokeless propellant for fireworks. Background technique [0002] Fireworks, also known as firecrackers, pyrotechnics, and pyrotechnics, were invented earlier by the working people of the Han nationality. They are mainly used in military affairs, grand ceremonies or performances. In modern China and the world, they are the only activities that can release fireworks in the same event on the same day. For New Years Eve activities. [0003] In the current actual production, the firework propellant has been using black powder (military nitrate) composed of potassium nitrate, charcoal and sulfur, which will produce a large amount of black smoke when burning, which will affect the effect of fireworks. A large amount of oxides and residues of carbon, sulfur, and potassium remain, which seriously pollutes the environment. At the same time, during the production...
