Problems solved by technology

Because the auxiliary ingredients are not clear and the ratio is not specific, the reference effect is not obvious. In addition, the ignition standard of the insensitive electric ignition head is 1A, 1W, and 5min without ignition, and 5A, 5W, and 50ms must be ignited, that is, the activation current is 5A. , The reliable ignition time is 50ms, which improves the index requirements of the insensitive electric ignition head. Therefore, compared with the above-mentioned pyrotechnic agents, a pyrotechnic agent with the characteristics of high ignition point, large output heat, and safe use is studied to meet the insensitivity of thermal batteries. Sensitivity needs are especially important

Abstract

The invention belongs to the technical field of pyrotechnic compositions, and particularly relates to a pyrotechnic composition for an insensitive electric ignition head and a preparation method and application of the pyrotechnic composition. The pyrotechnic composition is composed of a reducing agent, an oxidizing agent, and a binder for molding. The reducing agent is composed of magnesium powder, zirconium powder and aluminum powder, the oxidizing agent is barium peroxide, and the binder is composed of absolute ethyl alcohol and polyvinyl butyral. The pyrotechnic composition for the insensitive electric ignition head is applied to ignition of a thermal battery, has the advantages of being high in ignition point, large in output energy, safe to use and the like, and can meet the ignitionrequirement of the thermal battery.

Description

technical field [0001] The invention belongs to the technical field of pyrotechnic agents, in particular to a pyrotechnic agent for an insensitive electric lighter and its preparation method and application. 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 power output, long storage life...
