Description
Technical field
The present invention a kind of aqueous granular viscous explosive formula and preparation process of Storage period length, belong to civil detonation technology neck
Domain.
Background technology
Viscous explosive is mainly used in mine pumping apical pore powder charge.Need explosive mechanical sensitivity low, dose is returned in apical pore powder charge
Small, brisance is big, there is a higher water resistant ability, not only cementitious but also have free-running property.But general powdery viscous explosive with
Preferable viscosity, but the blocking of powder charge pipeline is easily caused in underground powder charge, to influence powder charge while increase powder charge process
Insecurity.Grain powder has preferable free-running property, but easily causes the anti-medicine of blasthole after powder charge, leads to that powder charge is unreal, explosive payload
Insufficient situation, to influence demolition effect.
Current aqueous granular viscous explosive, existing caking property appropriate have free-running property appropriate again, but due to containing water particle
Determine that the crucial semi-finished product adhesion agent water content of its performance is big in shape viscous explosive, the term of validity of the viscous explosive of making was at 3 days
Left and right, service life are short, it is necessary to carry out being blended for last procedure by specific user scene, leverage sticky grain in this way
The market development of shaped explosive charge.
Invention content
The invention overcomes the deficiencies of the prior art, and provides a kind of aqueous granular viscous explosives of Storage period length to match
Side and preparation process have the characteristics that Storage period is long, free-running property is good, caking property is good.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：A kind of Storage period length it is aqueous granular viscous
Property fried medicine composition, including ammonium nitrate, diesel oil and adhesion agent, the ammonium nitrate weight part ratio are 67%-
75%, the diesel oil weight part ratio is 3%-5%, and the adhesion agent weight part ratio is 23%-27%；
The adhesion agent matches：Powdery ammonium nitrate 44%-49%, powdery TNT 33%-38%, water 15%-17%, molecular weight are
8000000-1,000 ten thousand non-ionic polyacrylamide 1%-1.5%.
A kind of preparation process of the aqueous granular viscous explosive of Storage period length of the present invention, includes the following steps：
The first step：Adhesion agent is prepared；Polyacrylamide and powdery TNT are first subjected to input after just mixing uniformly, powdery ammonium nitrate is housed
In the mixing machine of water, rotate forward 2 to 3 circles, 2 to 3 circle of overturning breaks up rapidly material, after be blended after 2-3min the packaging that discharges；
Second step：Adhesion agent is sensitized；Adhesion agent is dispensed into the shading woven bag of 25kg, room temperature shading is sensitized 10 days；
Third walks：The preparation of granular viscous explosive；Ammonium nitrate is poured into blender, is puddled after pouring into diesel oil
It is even, adhesion agent is added afterwards, it is finished product to puddle after 4-5min.
The present invention has an advantageous effect in that compared with prior art：The present invention using powdery ammonium nitrate as oxidant,
The polyacrylamide of suitable molecular weight is chosen as gelling agent, with sensitizer, catalyst preparation at adhesion agent, through special process item
After part sensitization, it is blended into aqueous granular viscous explosive.The existing good free-running property of the viscous explosive is convenient for underground truck charging,
It is again cementitious, keep the anti-dose of the explosive of filling small, be bonded in blasthole, while also having stable Storage period（30 days or more）,
Convenient for long distance transportation, lay a solid foundation for the market exploitation of such viscous explosive.
