Abstract

The invention discloses a gel propellant adopted as an aerospace fuel, a preparation method and uses thereof. The preparation method comprises: adding acetal substituted glucamide to a solvent to achieve the acetal substituted glucamide content of 1-30 mg / mL, heating to a temperature of 150-180 DEG C under stirring, stopping the stirring, and cooling to a room temperature, wherein the solvent is JP-10 or RP-1. According to the present invention, the gel propellant adopted as the aerospace fuel has heat reversibility and thixotropy, has the high instantaneous recovering rate after the thixotropy, and can achieve the completely recovering state; the rheological property of the gel can be improved by adding the combustion-supporting agent nanometer powder; and the obtained gel propellant can be used as the aerospace fuel.

Description

technical field

[0001] The invention belongs to the technical field of fine chemicals, and in particular relates to a gel propellant used as an aerospace fuel, a preparation method and an application. Background technique

[0002] Supramolecular gels are usually formed by self-assembly of low-molecular-weight gelling factors (molecular weight <3000) through non-covalent interactions (such as hydrogen bonds, van der Waals interactions, π-π stacking interactions, hydrophobic effects, electrostatic interactions, etc.) A soft material between liquid and solid. Due to the dynamic reversibility of non-covalent bonds, the formation and depolymerization of supramolecular gels can easily occur, which endows this kind of soft materials with excellent thermal processability, recyclability, self-healing properties, and environmental irritation. Responsiveness.

[0003] Commonly used organic fuels are alcohols, H 2 o 2 , Hydrazine, and high-density liquid hydrocarbon fuels (JP-5, ...
