Problems solved by technology

[0002] At present, the fireworks industry in the whole country and even the whole world is using black powder (military nitrate) in a large number to make fireworks for medicinal purposes. The formula of black powder is: potassium nitrate 75% sulfur 10% hemp stalk charcoal 15%. Although black powder has good ignition performance, Black powder burns with a lot of smoke and releases sulfur dioxide and sulfides to pollute the environment

Embodiment 1

[0007] Embodiment 1: described environment-friendly firework propellant is made up of the component of following weight and number ratio: dinitramide ammonium (AND) 20 parts, nitrocellulose 15 parts, polyvinyl alcohol 3 parts; Grains, that's it.

[0008] The difference between Examples 2-9 and Example 1 is that the distribution ratio of the components is different, see the following table for details: Among them, the mixture of AND and DNAFO only needs to be mixed uniformly according to the general method.

[0009]

[0010] The present invention is not limited to the above-mentioned specific examples. After a large number of experimental verifications, within the proportioning range provided by the present invention, any proportion mixture of each component can meet the purpose of the present invention: when used as a fireworks propellant, all On the premise of ensuring the launch performance, the reduction of smoke from fireworks can be realized. Compared with the existin...

Abstract

The invention discloses an environment-friendly propellant, consisting of the following components in parts by weight: 20-60 parts of oxidant, 15-60 parts of nitrocellulose and 3-8 parts of adhesive, wherein the oxidant is selected from one of ammonium dinitramide and binitro azoxy bifurazan or a mixture of the two components in any proportion; the adhesive is selected from polyvinyl alcohol or strong adhesive powder. By adopting the formula, the smoke volume generated by combustion of the propellant can be greatly reduced, meanwhile, under the same working condition, compared with military nitrate, the use amount of the propellant can be reduced by 15-30%, and the emission height is equivalent.

Description

technical field [0001] The invention relates to a propellant for fireworks. Background technique [0002] At present, the fireworks industry in the whole country and even the whole world is using black powder (military nitrate) in a large number to make fireworks for medicinal purposes. The formula of black powder is: potassium nitrate 75% sulfur 10% hemp stalk charcoal 15%. Although black powder has good ignition performance, Black gunpowder burns with large smoke and emits sulfur dioxide and sulfides to pollute the environment. Contents of the invention [0003] In order to solve the above-mentioned disadvantages, the technical problem to be solved by the present invention is to provide a fireworks propellant that reduces smoke and is beneficial to environmental protection. In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is an environmentally friendly propellant, which is characterized in that the propell...
