For dimethylbenzene or ethyleneglycol monophenylether.
Wherein, the purpose for adding graphite is to make Composite Propellant Slurry more insensitiveness, and increases the electric conductivity of Composite Propellant Slurry；
The purpose for adding polyether-modified dimethyl siloxane solution (FC-606) is to reduce the pore that propellant is produced during filling,
Increase degree of packing；In principle, according to using the performance such as the burn rate of htpb solid propellant medicine slurry can prepare height, in and it is low
The explosive-source explosive post of explosion velocity.
The explosive-source explosive post prepared using discarded htpb solid propellant medicine slurry, by explosive-source explosive post main charge 1, housing 2, propagation of explosion
Powder column 3, detonator base 4, thread ending cover 5 are constituted, it is characterised in that：Described explosive-source explosive post main charge 1 is seated in housing 2,
Described booster gains 3 is arranged in the pressure hole of 1 afterbody of explosive-source explosive post main charge, and detonator base 4 is arranged on 2 port of housing,
Thread ending cover 5 is arranged on into 2 port of housing；Described explosive-source explosive post main charge 1 is by the discarded htpb solid propellant medicine of utilization
Prepared by slurry.
The preparation method of explosive-source explosive post, is comprised the steps of successively：
First step, by mass percentage precise htpb solid propellant medicine slurry, polyether-modified dimethyl siloxane
And graphite, it is stirred in being added to mixing kettle；
Second step, the medicine slurry being stirred is loaded in housing 2, and ready pressure punch die is inserted into medicine slurry
In；
Third step, the housing 2 for installing medicine slurry is positioned in baking oven and is solidified；
Four steps, after the completion of solidification, takes out housing 2, extracts pressure punch die, ready booster gains is inserted into shake
In the pressure hole of source powder column main charge 1；
Detonator base 4 is arranged on 2 port of housing and is sealed by the 5th step；
Thread ending cover 5 is arranged on 2 port of housing, and is sealed by the 6th step, and whole explosive-source explosive post has made
Finish.
The explosive-source explosive post that the present invention is prepared takes full advantage of discarded solid-propellant pulps, production cost than relatively low,
Water-resistance is good, and the high explosion-speed seismic explosive columns for preparing also reached high explosion-speed seismic explosive columns in national standard (explosion velocity >=
Technical requirements 5000m/s), and have obvious advantage than the common ammonium high explosion-speed seismic explosive columns (explosion velocity is 5300m/s) of ladder, can
To meet the index request of domestic high density focus marketing users.
