Room-temperature-cured-type clean solid propellant

Abstract

The invention provides a room-temperature-cured-type clean solid propellant. The room-temperature-cured-type clean solid propellant is prepared from, by mass, 55%-70% of chlorine-free oxidizing agents, 5%-20% of metal fuels, 5%-15% of plasticizers, 5%-10% of amine-terminated polyether adhesives, 0.5%-1.0% of isocyanate curing agents and 0.01%-3% of function auxiliaries. According to the room-temperature-cured-type clean solid propellant, the detect that in the prior art, due to the fact that an oxidizing agent ammonium perchlorate is used in a compound solid propellant, a large amount of HCl gas is contained in a combustion product, and atomospheric pollution is serious is overcome; the amine-terminated polyether adhesives with the high reaction activity are introduced into a compound solid propellant system, and a cross-linking and curing reaction of terminal amino groups and the isocyanate curing agents is utilized, so that room-temperature curing of the amine-terminated polyether propellant is achieved; no HCl gas exists in the combustion product by adding the chlorine-free oxidizing agents.

Description

technical field [0001] The invention relates to a clean solid propellant solidified at room temperature and belongs to the field of composite solid propellants. Background technique [0002] Solid rocket motors powered by solid propellants have been widely used in the fields of strategic and tactical missiles and launch vehicles due to their simple structure, high reliability, good maneuverability, strong survivability, and low cost. Because solid propellants use chemical substances as working medium fuels, most of their components and combustion products are toxic and harmful chemical components, which cause certain harm to human body and environment. For a long time, ammonium perchlorate (AP) has been the main oxidant in composite solid propellants, and its mass fraction in the propellant often reaches about 70%. Because the combustion products of AP-containing composite solid propellants contain a large amount of HCl gas, HCl easily forms acid mist in the presence of wat...

AI Technical Summary

Problems solved by technology

Because the combustion products of AP-containing composite solid propellants contain a large amount of HCl gas, HCl easily forms acid mist in the presence of water, pollutes the environment, destroys ozone in the atmosphere, and produces a greenhouse effect, which cannot meet environmental protection requirements.
