Problems solved by technology

There are disadvantages such as easy to be affected by moisture, low safety performance, and easy to cause environmental pollution (the smog is relatively large)
In addition, this type of black powder has a low ignition point (398°C), sulfur content, high friction sensitivity, impact sensitivity and moisture absorption rate
[0003] The existing sulfur-free propellant consists of potassium perchlorate, charcoal, potassium hydrogen terephthalate and resin. This sulfur-free propellant has the problems of being susceptible to moisture and high rate of impact ignition, and cannot be applied to production and daily life. Therefore, It is necessary to develop a sulfur-free propellant that is safe, environmentally friendly and has good gunpowder performance

Abstract

The invention provides a propellant and a preparation method thereof. The propellant is prepared from the following components: 30-50 parts of potassium permanganate, 8-20 parts of binder, 10-20 partsof potassium hydrogen phthalate and 20-40 parts of combustible agent, wherein the combustible agent is a mixture of magnesium powder and charcoal dust. The propellant is low in friction and impact sensitivity, small in moisture absorption rate, high in thrust and also capable of reducing environmental pollution.

Description

Technical field [0001] The invention belongs to the field of gunpowder, and more specifically, relates to a propellant and a preparation method. Background technique [0002] With the development of society, propellants are widely used in daily life and celebration activities. Most of the existing propellants are black powder, and its main ingredients are potassium nitrate, sulfur, fir powder, etc., which use traditional manufacturing methods. It has been used for hundreds of years. The main working principle is to ignite the black powder through the fuse to generate an upward force to push the firework cartridge into the air. There are shortcomings such as easy to be damp, low safety performance, easy to cause environmental pollution (its smoke is large). In addition, this kind of black powder has a low ignition point (398°C), sulfur content, high friction sensitivity, impact sensitivity and moisture absorption rate. [0003] The existing sulfur-free propellant is composed of po...
