Abstract

The invention discloses a sulfur-free environment-friendly gun propellant which comprises the following components in parts by weight: 65 parts of potassium acid phthalate, 15 parts of hemp stem carbon powder, 10 parts of an epoxy resin, 2 parts of graphite powder and 5 parts of lime. The gun propellant manufactured according to the formula is applied to display shells, potted flowers, colored bead barrels, display shell rocket propulsion powder and the like. The sulfur-free environment-friendly gun propellant is excellent in safety performance indexes, the friction sensitivity and percussion sensitivity degree are zero, and the potential safety hazards are eliminated; according to the formula, the sulfur component is completely eliminated, so that pollution of sulfur dioxide and sulfides on the environment is eliminated during firework display; and moreover, the gun propellant does not contain forbidden materials; and the environmental protective performance is greatly improved.

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. Moreover, black powder is too sensitive and has high mechanical sensitivity. It is a very dangerous pyrotechnic drug that is prone to explosion. It is not conducive to transportation, storage and use, leading to frequent major safety accidents in the fireworks industry and black powder production enterprises, resulting in personal casualties and property losses. Contents of the invention [0003] In order to solve the above disadvantages, the te...
