Abstract

The invention discloses a high-burning-rate pyrotechnic compound for activating thermal batteries. The pyrotechnic compound comprises an oxidizing agent, a reducing agent and a forming adhesive, and the oxidizing agent comprises potassium chlorate and lead chromate. The invention further discloses a preparation method of the pyrotechnic compound. The high-burning-rate pyrotechnic compound is a novel pyrotechnic compound for the thermal batteries and applied to activation of the thermal batteries, and the pyrotechnic compound has the advantages of high burning speed, reliable activation, no jump burning and micro-short circuit, safe and convenient to use and the like. The thermal batteries can be more rapidly activated, rapid activation requirements of the thermal batteries are completely met, and the pyrotechnic compound is applicable to the thermal batteries in the field of quick response and the like and particularly applied to rapid activation of the thermal batteries.

Description

technical field [0001] The invention belongs to the technical field of chemical materials, and in particular relates to a high-burning-rate pyrotechnic agent for thermal battery activation, a preparation method and application thereof. Background technique [0002] Thermal battery (thermal battery), also known as heat activated reserve battery (heat activated reserve battery). The thermal battery is a molten salt battery that is ignited and started by a pyrotechnic heat source. It has the advantages of high specific energy and no maintenance and maintenance during the storage period. When the thermal battery is stored, the electrolyte is a non-conductive solid. When in use, an electric ignition head or a firing pin mechanism is used to ignite the heating agent inside, so that the electrolyte melts into an ion conductor and is activated as a reserve battery. As a kind of reserve energy, thermal battery has the characteristics of short activation time, fast response, high pow...
