Problems solved by technology

[0002] At present, the propellants in domestic solid oxygen generators generally use zirconium powder as the main raw material, and barium nitrate or barium peroxide is used as the oxidant. Due to the limitation of its composition, it has defects such as unstable ignition performance. Barium is easy to absorb moisture and deteriorate, and barium peroxide is easy to decompose, so the product cannot be stored for a long time

Abstract

The invention discloses oxygen candle starting mix and a preparation method thereof. The oxygen candle starting mix is prepared from the following components in parts by mass: 70-90 parts of barium chromate, 5-15 parts of a metal monomer, 3-10 parts of an adhesive and 0-5 parts of chlorate. The preparation method disclosed by the invention comprises the following step: pressing the barium chromate, the metal monomer, the adhesive and the chlorate according to the formula proportions, thereby obtaining the oxygen candle starting mix. As zirconium powder is replaced by magnesium powder or aluminum powder, magnesium oxide on the surface of the magnesium powder is a catalyst for decomposing chlorate, the decomposition temperature of the chlorate is reduced, harmful gas nitrogen oxides generated from detonating caps of actuators can be rapidly combusted and absorbed, and meanwhile combustion residues are loosened without swelling, thus being safe and reliable.

Description

technical field [0001] The invention relates to oxygen candle technology, in particular to a propagating powder for oxygen candles. Background technique [0002] At present, the propellants in domestic solid oxygen generators generally use zirconium powder as the main raw material, and barium nitrate or barium peroxide is used as the oxidant. Barium is easy to absorb moisture and deteriorate, and barium peroxide is easy to decompose, so the product cannot be stored for a long time. Contents of the invention [0003] Aiming at the defects or deficiencies of the prior art, the object of the present invention is to provide a kind of propellant for oxygen candle. [0004] The fire transfer agent for oxygen candle provided by the invention is made of 70-90 parts by mass of barium chromate, 5-15 parts by mass of simple metal, 3-10 parts by mass of binder and 0-5 parts by mass of chlorate . [0005] The elemental metal of the present invention is one or a mixture of two or mor...
