A kind of sulfur-free ring safe agent propellant

Abstract

The invention discloses sulfur-free ring stabilizing agent propellant powder which consists of the following components in parts by weight: 70 parts of an oxidant, 34 parts of a burnable agent, 6 parts of an adhesive, 2 parts of a stabilizing agent, 2 parts of an anti-aging agent, 1 part of a catalyst and 2 parts of an antismoke agent which are uniformly mixed according to a general method, wherein the oxidant is a mixture consisting of potassium perchlorate, amine perchlorate and barium nitrate; the burnable agent is a mixture consisting of potassium hydrogen terephthalate, potassium acid phthalate, nitrocellulose, purified terephthalic acid and hemp stem carbon powder; the stabilizing agent adopts calcium stearate; the anti-aging agent adopts calcium phthalate; the catalyst adopts copper oxide; the antismoke agent adopts aluminum hydroxide; the adhesive is selected from one or a mixture of multiple of phenolic resin, strong adhesive powder, glutinous rice flour and polyvinyl alcohol according to any ratio. The sulfur-free ring stabilizing agent propellant powder is high in power capability and excellent in safety performance indexes and has excellent storage stability, and the environment-friendly performance is greatly improved.

Description

Technical field [0001] The invention relates to a propellant for fireworks. Background technique [0002] At present, the firework industry in the whole country and the whole world is using black powder (military nitrate) as firework propellant. The formula of black powder: potassium nitrate 75% sulfur 10% hemp charcoal 15%. Although black powder has good ignition performance, Black gunpowder is a low-speed gunpowder, which produces deflagration without detonation when burned. It has poor performance, low energy, large combustion smoke and emits sulfur dioxide and sulfide to pollute the environment. Moreover, black powder has high mechanical sensitivity, poor impact sensitivity and friction sensitivity, and its high sensitivity has led to frequent major safety accidents in the fireworks industry and black powder production enterprises, resulting in personal injuries and property losses. In addition, black powder has shortcomings such as easy moisture absorption. [0003] The disa...

AI Technical Summary

Problems solved by technology

[0002] At present, the firework industry in the whole country and even the whole world is using black powder (military nitrate) in a large number to make fireworks. Black powder is a kind of low-speed gunpowder, which produces deflagration but not detonation when it burns. It has poor work ability, low energy, large combustion smoke and releases sulfur dioxide and sulfide to pollute the environment.

Moreover, the mechanical sensitivity of black powder is high, and the impact sensitivity and friction sensitivity are poor. The high sensitivity leads to major safety accidents in the fireworks industry and black powder production enterprises, resulting in personal casualties and property losses.

Moreover, black powder also has disadvantages such as easy moisture absorption.

[0003] The disadvantages of black powder are the consensus in the industry, and the industry has also carried out the research and development of black powder substitutes, but so far, these substitutes have often achieved improvement in a single performance index, but have not achieved comprehensive performance in terms of safety and environmental protection. Breakthrough, difficult to achieve the goal of replacing black powder
