Smokeless propellant powder with safe, environmental-friendly and porous structure for fireworks

Abstract

The invention provides smokeless propellant powder with a safe, environmental-friendly and porous structure for fireworks. The smokeless propellant powder comprises the following components in parts by weight: 30-50 parts of high-energy oxidizer, 1-5 parts of catalyst, 10-80 parts of single-base powder, 1-5 parts of stabilizer, 1-5 parts of adhesive, 10-30 parts of primary explosive, 10-20 parts of pore foaming agent and 1-5 parts of combustion speed improving agent. The smokeless propellant powder is smokeless and environmental-friendly, and can ensure that no residual propellant exists in a canister launcher after launching; and the smokeless propellant powder has the characteristics of strong ignition capacity, easiness in ignition, high-temperature combustion products, greatly enhanced capacity of igniting an effect chemical, and low hygroscopicity.

Description

technical field [0001] The invention relates to the field of fireworks and firecrackers, in particular to a safe, environment-friendly and porous micro-smoke propellant for launching fireworks. Background technique [0002] The current fireworks propellant produces a large amount of smoke after being set off, which seriously affects the effect of setting off the fireworks, and the main source of the smoke is the use of black powder propellant. In order to solve the problem of smoke generated during fireworks display, the fireworks industry has developed the use of decommissioned gunpowder powder as the propellant. Compared with black powder, the smoke is much reduced and the launch force is large. However, under the existing propellant charge conditions Under the circumstances, this kind of propellant has poor ignition ability to the effect drug, resulting in residual drug left in the launch tube after ignition, which seriously affects the effect of fireworks.
