Abstract
The invention discloses a kind of carbon dioxide liquid-gas phase transition exothermic mixtures, include the ingredient of following parts by weight：10~20 parts of 50~75 parts of potassium hyperchlorate, 15~25 parts of ammonium oxalate and salicylic acid.Normal temperature and pressure of the present invention does not burn, does not explode, and impact sensitivity, Friction sensitivity, flame sensitivity and electrostatic sensitivity are qualified；The excitation ability combustion heat release under the pressure of more than 4MPa, securely and reliably.
Description
Technical field
The present invention relates to explosion material therefor fields, and in particular to a kind of carbon dioxide liquid-gas phase transition exothermic mixture.
Background technology
Carbon dioxide fracturing device is by thermal evaporation expansion, quick release high pressure gas fracture rock using liquid carbon dioxide
Or coal breakage, it solves and blew exploitation up with dynamite in the past, the defects of destructive is big in presplitting and the high ore body of risk crushes, is mine
Safety is exploited and presplitting provides firm guarantee, is generally applicable to operation on coal mine and non-coal mine.Carbon dioxide explosion has noise
The advantages such as low, the small, safety and environmental protection of vibrations, are widely used in various minings.
Exothermic mixture electrothermal calefactive rate that traditional carbon dioxide fracturing equipment uses is slow, calorific value is small, it is difficult to meet carbon dioxide
The need of work of phase transformation fracturing influences the normal work of carbon dioxide fracturing device；And impact sensitivity, friction sensitivity, flame
Sensitivity and electrostatic sensitivity are excessively high, to production, transport, storage, using bringing very big security risk.
Invention content
A kind of carbon dioxide liquid gas is provided the purpose of the invention is to overcome above-mentioned defect in the prior art
Phase transformation exothermic mixture has safety and environmental protection, moment explosion, applied widely and four degree（Impact sensitivity, friction sensitivity, flame sensitivity
And electrostatic sensitivity）The advantage of performance safety, and preparing process is simple, flexible and convenient to use, use easy to spread.
The purpose of the present invention is achieved through the following technical solutions：
A kind of carbon dioxide liquid-gas phase transition exothermic mixture includes the ingredient of following parts by weight：50~75 parts of potassium hyperchlorate, ammonium oxalate
15~25 parts and 10~20 parts of salicylic acid.
As a further improvement on the present invention, the carbon dioxide liquid-gas phase transition exothermic mixture include following parts by weight into
Point：13~18 parts of 60~70 parts of potassium hyperchlorate, 18~23 parts of ammonium oxalate and salicylic acid.
As a further improvement on the present invention, the carbon dioxide liquid-gas phase transition exothermic mixture include following parts by weight into
Point：15 parts of 65 parts of potassium hyperchlorate, 20 parts of ammonium oxalate and salicylic acid.
The present invention has the advantages that：
（1）Electrothermal calefactive rate is fast, and moment can be carbon dioxide gasification, and then carbon dioxide is made to generate huge expansive force in moment,
Achieve the purpose that mining；
（2）It does not burn, explode under normal temperature and pressure, impact sensitivity, friction sensitivity, flame sensitivity and electrostatic sensitivity are qualified, will
Production, transport, storage and the security risk in substantially reduce；
（3）Ability combustion heat release is lighted under the pressure of more than 4MPa, securely and reliably；
（4）Prepare simple, easy to operate, detonation synchronization, flexible and convenient to use, use easy to spread.
