Description

A kind of temperature-resistant oxygen candle
Technical field
The present invention relates to a kind of Chemical Oxygen Source prescription, be specifically related to a kind of temperature-resistant oxygen candle of sodium chlorate.
Background technology
The solid state chemistry oxygen generator is to utilize rich oxygen containing oxymuriate or perchlorate generation pyrolysis to emit the emergency oxygen supply equipment of new generation of the principle development of oxygen.The advantage of solid state chemistry oxygen generator is: the life-span is very long, need not spare part, ensures stronger; The oxygen-producing amount height, under the condition that produces equal oxygen, the volume of oxygen candle has only 1/3 of high-pressure oxygen cylinder volume, for the transportation of solid state chemistry oxygen generator, storage, layout are provided convenience; The solid state chemistry oxygen generator can carry out oxygen supply according to the oxygen supply mode of prior design, need not to regulate, and uses simple, reliable; Oxygen candle stores and uses all under atmospheric pressure state, does not have that Keep Clear-High Voltage.The solid state chemistry oxygen generator is non-maintaining, can reduce the maintenance cost behind the equipment.Solid state chemistry oxygen generator apparatus of oxygen supply now has been widely used in boats and ships naval vessels, aerospace, mine and various disaster field such as save oneself as the lifesaving emergency oxygen apparatus.
Chinese patent patent of invention specification sheets CN89100611.7 uses the catalyzer of the mixture of cobalt oxide or cobalt oxide and Manganse Dioxide as the sodium chlorate decomposition, uses lithium peroxide to make antichlor.This prescription catalyzer proportion is bigger, has both increased the weight of oxygen candle, has reduced available oxygen content, also can cause prescription to temperature sensitive, influences the oxygen candle and lights reliability and oxygen supply stability.Lithium peroxide belongs to somewhat expensive reagent, and domestic can't production, can only dependence on import, and cause oxygen candle cost higher.
Summary of the invention
The object of the present invention is to provide a kind ofly easily light, flameholding, temperature-resistant oxygen candle.
Technical solution of the present invention is (herein except that specifying, the raw material mixing ratio is mass ratio among the present invention): the raw material that comprises following mass percent is suppressed the main candle body that forms: sodium chlorate 72 ~ 85, fuel 1 ~ 10, stablizer 1 ~ 15, catalyzer 0.5 ~ 1, chlorine-inhibiting agent 2 ~ 6, binding agent 4 ~ 10.
There is inflammable medicine layer the top of main candle body of the present invention, and described inflammable medicine layer comprises the raw material of following mass percent: sodium chlorate 85 ~ 90, fuel 1 ~ 3, stablizer 1.5 ~ 5, catalyzer 1 ~ 4, chlorine-inhibiting agent 2 ~ 6.
Between inflammable medicine layer of the present invention and the main candle body transitional medicine layer is arranged, described transitional medicine layer comprises the raw material of following mass percent: sodium chlorate 80 ~ 92, fuel 1 ~ 7, stablizer 1 ~ 5, catalyzer 0.5 ~ 2, chlorine-inhibiting agent 2 ~ 6, binding agent 0 ~ 6.
Fuel of the present invention is the one or more combination in titanium valve, iron powder or the magnesium powder.
Stablizer of the present invention is the one or more combination of potassium perchlorate or silica flour.Add potassium perchlorate and silica flour, can make the oxygen candle have the higher sensitivity of lighting on the one hand, effect is the stability that improves the oxygen candle on the other hand, and it is steady to make it put oxygen.
Catalyzer of the present invention is the one or more combination of cobaltous hydroxide or cobalt chloride or cobalt oxide.
Chlorine-inhibiting agent of the present invention is the one or more combination of barium peroxide or sodium peroxide.Adding chlorine-inhibiting agent, is the chlorine of emitting when absorbing sodium chlorate and potassium perchlorate generation side reaction, emits oxygen simultaneously.Compare lithium peroxide, barium peroxide or sodium peroxide starting material wide material sources, cost is lower.
Binding agent of the present invention is kaolin or diatomaceous one or more combination.Add binding agent kaolin or diatomite, make oxygen candle powder column have enough intensity on the one hand, play skeleton function on the other hand again, prevent combustionmaterial fusion trickling.
The present invention can be the promptly main candle body of one deck structure.Also can be double-layer structure: inflammable medicine layer, main candle body.
The present invention can be three-decker and from top to bottom is followed successively by: inflammable medicine layer, transitional medicine layer, main candle body.Catalyzer plays the effect that reduces the sodium chlorate decomposition temperature.As a whole, the catalyzer proportion is less, is 0.5 ~ 4%.The present invention from top to bottom, catalyst content reduces gradually, binder content increases gradually.This be because, catalyst themselves is relatively responsive to temperature, catalyst activity height during high temperature, catalyst activity is lower during low temperature, catalyst content is many more, oxygen candle (speed of oxygen supply) is responsive more to temperature.Therefore, the low levels catalyzer can guarantee that temperature fluctuation is less to the oxygen whole oxygen supply influence of lighting up.
The present invention's advantage compared with prior art is:
(1) use catalyzer can reduce the sodium chlorate decomposition temperature, but content should not be low excessively, lights reliability in order to avoid influence the oxygen candle.The low levels catalyzer both can effectively reduce the sodium chlorate decomposition temperature, can guarantee that again temperature fluctuation is less to oxygen candle entire effect, and the oxygen candle all can reliably be lighted at high and low, normal temperature.
(2) the oxygen candle is multilayered structure, is followed successively by inflammable medicine, (transitional medicine), main candle body from top to bottom.The ratio that inflammable medicine accounts for the oxygen candle is little, and the flame sensitivity height is lighted by ignition powder easily.
(3) oxygen is lit up from top to bottom, and flame sensitivity reduces gradually, because kaolin or diatomaceous adding, oxygen candle intensity strengthens gradually, guarantees that products of combustion forms skeleton, and not fusion is trickled.
(4) oxygen candle Stability Analysis of Structures, prescription is rationally finely tuned on this basis, promptly applicable to the oxygen generator of various uses, as small-sized self-rescuer, large-scale oxygen supply unit etc., is applied to boats and ships naval vessels, aerospace, mine and various disaster field such as save oneself.
