Problems solved by technology

[0002] In the background technology, at present, the propagating agent in domestic solid oxygen generators generally uses magnesium powder as the main raw material, and barium nitrate and barium peroxide are used as the oxidizing agent. Due to the limitation of its composition, it has a serious defect of unstable ignition performance. At the same time, barium nitrate as an oxidant is easy to absorb moisture and deteriorate, and barium peroxide is easy to decompose and unstable, which cannot meet the requirements of long-term storage of products

Embodiment Construction

[0016]

[0017] The technological process of making solid oxygen generator of the present invention to pass gunpowder tablet sees attached figure 1 .

[0018] In the above formulas 1, 2, 3 and 4, when processing raw materials, zirconium powder and zirconium hydride are first dehydrated, dried at 80°C, ferric oxide is dried at 100°C, zirconium powder, zirconium hydride , ferric oxide, and diatomaceous earth are mixed according to the formula ratio. After mixing and sieving, the average particle size is 0.15-0.85mm. Add 8-10% shellac alcohol solution, stir evenly, and bake at 60°C for 3 Hour.

Abstract

The invention discloses a starting mix of a solid oxygen generator, belonging to the technical field of explosives. The starting mix of the invention is mainly suitable for quickly igniting an oxygen generating grain to generate oxygen when the solid oxygen generator is impacted and ignited, and has the main technical characteristic of comprising the following components in percentage by weight: 40-70 of ferric oxide, 5-25 of zirconium powder, 10-30 of zirconium hydride, 1-15 of kieselguhr and 1-10 of shellac varnish, wherein the zirconium powder is substituted for magnesium powder, and the ferric oxide is substituted for barium nitrate and barium peroxide as oxidizers. The starting mix has the characteristics of moisture protection, water resistance, oxidation protection and the like, has good ignition property and safety, and can meet the requirement of long-term storage of products.

Description

technical field [0001] The invention relates to a powder for transmitting a solid oxygen generator, which belongs to the technical field of explosives and is mainly suitable for rapidly igniting an oxygen-making powder column to generate oxygen when a solid oxygen generator is fired. Background technique [0002] In the background technology, at present, the propagating agent in domestic solid oxygen generators generally uses magnesium powder as the main raw material, and barium nitrate and barium peroxide are used as the oxidizing agent. Due to the limitation of its composition, it has a serious defect of unstable ignition performance. At the same time, the barium nitrate used as an oxidant is easy to absorb moisture and deteriorate, and the barium peroxide is easy to decompose and unstable, which cannot meet the requirements of long-term storage of products. In order to overcome these defects, the propellant of solid oxygen generator has been developed. Contents of the i...
