Environment-friendly firework propellant

Abstract

The invention discloses an environment-friendly firework propellant which is characterized by being composed of the following components in parts by weight: 10-65 parts of rare earth, 15-35 parts of potassium perchlorate, 10-20 parts of aluminum magnesium alloy, 5-20 parts of combustible agent, 2-5 parts of plant gum and 3-10 parts of resin, wherein the combustible agent is selected from any one or combined by any two from hemp xyloid stem carbon powder and Chinese fir carbon powder at any proportion, and the plant gum is a rice flour adhesive. The environment-friendly firework propellant is free of chlorate, small in horizontal launching force, low in moisture absorption property, low in impact and friction sensitivity, small in dosage of charges for preparing fireworks, slight in smoke, long in shelf life and displaying time, free of residues after displaying, good in physical and chemical stability, simple in processing technology and suitable for various firework propellants.

Description

technical field [0001] The invention relates to the field of fireworks medicaments, in particular to an environment-friendly fireworks propellant. Background technique [0002] In the prior art, the propellants used in the production of fireworks are black powder propellants composed of sulfur, potassium nitrate and charcoal. When the fireworks are set off, a large amount of smoke will be generated, and there will be black residues in the cylinder after setting off, which will not only seriously affect the Fireworks discharge effect, while causing serious pollution to the environment. Due to the high mechanical sensitivity of black powder propellant, it is easy to cause safety accidents such as explosion or fire when encountering mechanical friction or impact and collision during production and transportation, causing heavy property loss and endangering personal safety, so it is no longer suitable for current fireworks. requirements for safe production. In addition, the fi...

AI Technical Summary

Problems solved by technology

Since the smokeless / micro-smoke pharmaceutical composition produced by the existing configuration is mainly composed of nitrocellulose / nitrocellulose / retired army gunpowder single and double base powder, potassium perchlorate, ammonium perchlorate and other oxidants as the main components, the price of these smokeless pharmaceuticals is High, some processing and extraction processes are complicated, but the discharge effect is average, and there are still residual drug seedlings stored in the launch tube after discharge, which affects the economic benefits of enterprises

And have not found the micro-smoke type environmental protection firework propellant that can be widely used yet at present
