Abstract

The invention relates to a solid propellant and its preparation method and application. The solid propellant is composed of the following mass percentage components: oxidant: 60-65%, reducing agent: 32-38%, catalyst: 1-3%, dehydrating agent : 0.5‑1.5%. The preparation process is as follows: dissolve the reducing agent in water and heat to 140-145°C, then add the oxidizing agent, keep the heating temperature at 140-145°C until the water is evaporated, then add the catalyst and dehydrating agent, vacuum degas for 15-25min and then cool to 80-90°C, pressurize and place in a mold, cool to room temperature and open the mold to obtain a solid propellant. The solid propellant of the present invention is used as rocket fuel. Compared with the traditional solid propellant, the cost is lower, and the preparation method is safe and convenient. It can be widely used in civilian small solid rockets, and can meet the needs of meteorological exploration, high-altitude photography, scientific experiments, teaching demonstrations, etc. Requirements for small solid rockets required by the civilian industry.

Description

technical field [0001] The invention relates to a solid propellant and its preparation method and application, belonging to the technical field of solid propellant. Background technique [0002] Solid propellant is a kind of energy-containing composite material with specific properties. It is the power source of various solid motors of missiles and space vehicles. It is the power source material of solid rocket motors. It plays an important role in the development of missiles and aerospace technology. Generally, it can be divided into double base propellant, composite propellant and modified double base propellant. Currently, common high-energy solid propellants include HTPE propellants, NEPE propellants, GAP propellants, and modified double-base XLDB propellants. [0003] However, with the continuous development of science and technology, solid-fuel rocket technology, especially small solid-fuel rockets, is increasingly being used in civilian industries such as meteorologi...
