A kind of simulated solid propellant and preparation method thereof

Abstract

The invention relates to a simulated solid propellant and a preparation method thereof, in particular to a simulated solid propellant with good weather resistance, which belongs to the technical field of simulated composite solid propellants, and the simulated propellant is mainly used as solid propulsion in a non-combat environment Good weather resistance means that the propellant still maintains a deviation of not less than 85% of its mechanical properties after being stored for five years under the combined influence of sunlight, heat, wind, rain, and humidity. The simulated solid propellant density of the present invention is 1.4~2.0g / cm 3 It can be adjusted within a certain range; and it is not sensitive to light, humidity and temperature after being made into a drug, and does not need to take special moisture-proof protection measures, and its performance will hardly decrease during storage, and it will not cause corrosion to the shell.

Description

technical field [0001] The invention relates to a simulated solid propellant and a preparation method thereof, in particular to a simulated solid propellant with good weather resistance, which belongs to the technical field of simulated composite solid propellants, and the simulated propellant is mainly used as solid propulsion in a non-combat environment Good weather resistance means that the propellant still maintains a deviation of not less than 85% of its mechanical properties after being stored for five years under the combined influence of sunlight, heat, wind, rain, and humidity. Background technique [0002] Due to the application of non-combat environments such as model display, structural design assessment, counterweight, and military training, it is often necessary to use non-combustible propellants to make simulated solid motors in weapon development and equipment production. The non-combustible propellants used are called analog propellant. In addition to being...

Problems solved by technology

[0004] 1) The processing of raw materials is complex and needs to be crushed or sieved in advance to achieve different particle size gradations;

[0005] 2) The mechanical properties of the product are poor, and the maximum elongation is about 40%;

[0006] 3) The storage environment is harsh, and the product has strong hygroscopicity, so it needs to be stored in a dry environment;

[0007] 4) The casing is severely corroded, and sodium chloride and potassium chloride will increase the corrosion of the metal casing after moisture absorption;

[0008] 5) The cost is high, and the pretreatment and storage of materials increase the cost of the engine
