Abstract

The invention relates to a high-explosion-heat energy-containing micro-projectile, and belongs to the field of special damage. The energetic micro-projectile is composed of a fluoropolymer-based energetic micro-projectile basic formula and a high-explosion-heat reactant. The obtained product has the prominent characteristics that the effect of increasing the damage of explosion heat is achieved, the damage can be increased to 120%-200% of the damage of the original formula, and the product has the advantages of being free of sulfur and nitrogen, slight in smoke, high in explosion heat, high in safety and the like and can be widely applied to the fields of air anti-conduction, armor breaking damage and the like.

Description

technical field [0001] The invention relates to a preparation method of a high-explosive heat type energetic micro-projectile, which belongs to the technical field of special damage. Background technique [0002] Energetic micro-projectiles are a newly developed class of new concept damage energetic materials. The principle is to design polymer oxidants and metal reductants through the core-shell structure, and then produce them under high-energy conditions such as high-speed impact, high-temperature ignition or laser ignition. Under triggering, a rapid and violent oxidation-reduction reaction occurs, thereby releasing high temperature to the outside, using the gaseous effect of metal fluoride under high temperature conditions to achieve volume expansion of thousands of times, thereby further generating overpressure, and forming a compound such as high temperature and overpressure on the target. The damage effect has broad application prospects in the fields of air defense a...
