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
The present invention relates to a kind of starting mix of solid oxygen generator, belong to fiery explosive technical field, quick igniting system oxygen powder column produced oxygen when it mainly was applicable to solid oxygen generator percussion igniting.
Background technology
In background technology; Starting mix in the present domestic solid oxygen generator generally all is to be main raw material with the magnesium powder, and oxygenant adopts nitrate of baryta and peroxide of barium, owing to limited by its composition; Cause it to have the unsettled major defect of ignition characteristic; Nitrate of baryta as oxygenant exists the easy moisture absorption rotten simultaneously, and there is problems such as being prone to decompose instability in peroxide of barium, can not satisfy the requirement of product standing storage.For overcoming these defectives, starting mix of solid oxygen generator is developed.
Summary of the invention
Technical problem to be solved by this invention provides a kind of starting mix of solid oxygen generator; It substitutes the magnesium powder with zirconium powder, makes oxygenant with alternative nitrate of baryta of red oxide of iron and peroxide of barium, and it can effectively improve the static sparking sensitivity; Ignition characteristic and security are good, can satisfy the requirement of standing storage.
The technical scheme that the present invention solves its technical problem employing is that it is by following ingredients
Red oxide of iron 40～70
Zirconium powder 5～25
Zircoium hydride 10～30
Zeyssatite 1～15
Shellac varnish 1～10
Weight percent form.
The present invention compares the beneficial effect that is produced with prior art.
1, because with the alternative magnesium powder of zirconium powder, the zircoium hydride that contains in the zirconium powder can reduce the mechanical sensitivity of starting mix, the flare point of raising zirconium powder is beneficial to burning and difficult the generation exploded, and security is good.
2,,, can satisfy the long storage of product requirement so starting mix of solid oxygen generator of the present invention has moisture proof, waterproof, anti-oxidation characteristics because of red oxide of iron stable in properties as oxygenant.
3, because the mechanical sensitivity of starting mix of solid oxygen generator of the present invention is lower, the static flame sensitivity is reduced, ignition characteristic is good.
Description of drawings
Fig. 1 is a process flow sheet of processing starting mix of solid oxygen generator tablet of the present invention.
Embodiment
Process the technical process of starting mix of solid oxygen generator tablet of the present invention and see accompanying drawing 1.
In the above-mentioned prescription one, two, three, four; When carrying out the starting material processing; Zirconium powder and zircoium hydride at first dewater, and under 80 ℃ of temperature, dry, and red oxide of iron is dried under 100 ℃ of temperature; Zirconium powder, zircoium hydride, red oxide of iron, zeyssatite mix by the formula rate requirement, and its mean particle size is 0.15 behind the overmulling sieve
～0.85mm, add 8～10% shellac varnish spirituous solutions, stir, baking is 3 hours under 60 ℃ of temperature.
