Description
The present application claims priority to Korean Patent Application No. 10-2022
0047302, filed April 18, 2022, the entire contents of which is incorporated herein for all purposes
by this reference.
1. Field of the Disclosure
The present disclosure relates to an emulsion explosive composition based on hydrogen
peroxide and nitrate.
2. Description of the Related Art
Emulsion explosives, first developed in the 1960s, are explosives that are currently
widely used around the world. Currently available emulsion explosives are based on
ammonium nitrate, which inevitably generates toxic NOx gas after blasting. Recently, increasing interest in the environment and the issue of blasting pollution have led to the
development of NOx-free products that can fundamentally remove NOx gas. In addition, explosives using hydrogen peroxide as an oxidizing agent, instead of ammonium nitrate, have
been developed.
Since then, research on the composition using nitrate and hydrogen peroxide as
oxidizing agents has been conducted. Compared to products using only hydrogen peroxide, a wide range of specific gravity is available, thereby extending the range of available energy and enabling selective use of the power of gunpowder depending on the usage environment.
In addition, the advantages of reducing NOx gas generation, compared to existing
ammonium nitrate-based emulsions, while partially compensating for the low energy generated
when using only hydrogen peroxide as an oxidizing agent can be obtained (I. Fullelove, M.
Araos & I. Onederra, Detonation performance of novel hydrogen peroxide and nitrate based
hybrid explosives (2017)).
However, hydrogen peroxide-based emulsion to which nitrate is added undergoes a self
gassing reaction in which hydrogen peroxide and nitrate react and are decomposed due to the
high reactivity of hydrogen peroxide, thereby generating 02 gas, particularly the self-gassing
reaction being promoted at a temperature of 30°C or higher.
Therefore, there is a demand for developing technologies capable of solving the above
self-gassing problem.
The present disclosure has been made to solve the above problems of the related art, and
an objective of the present disclosure is to provide an emulsion explosive composition based on
hydrogen peroxide and nitrate capable of being stably and safely used by improving self-gassing
problems.
The present disclosure provides an emulsion explosive composition containing: 80% to
95% by weight of an oxidizing agent aqueous solution containing hydrogen peroxide, nitrate,
and diethylene triamine penta(methylene phosphonic acid) (DTPMPA); 0.1% to 10% by weight
of an emulsifier; and 2% to 15% by weight of an oil.
An emulsion explosive composition of the present disclosure can solve self-gassing problems of an emulsion explosive composition based on hydrogen peroxide and nitrate, thereby enabling the explosive emulsion to be stably and safely used.
Hereinafter, the present disclosure will be described in detail.
An emulsion explosive composition of the present disclosure contains: 80% to 95% by
weight of an oxidizing agent aqueous solution containing hydrogen peroxide, nitrate, and
diethylene triamine penta(methylene phosphonic acid) (DTPMPA); 0.1% to 10% by weight of
an emulsifier; and 2% to 15% by weight of an oil.
Emulsion explosive compositions based on hydrogen peroxide and nitrate have a
disadvantage in that safety and stability are deteriorated due to self-gassing, in which hydrogen
peroxide and nitrate react and are decomposed, thereby generating 02 gas due to the high
reactivity of hydrogen peroxide. The present disclosure is characterized by minimizing such
self-gassing problems.
The oxidizing agent aqueous solution may contain 10% to 45% by weight of the
hydrogen peroxide, 10% to 50% by weight of the nitrate, 0.1% to 15% by weight of the
DTPMPA, and 10% to 45% by weight of water.
In the above numerical range, 0.1% to 10% by weight of the DTPMPA is preferably
contained, and 0.5% to 5% by weight of the DTPMPA is more preferably contained.
In the present disclosure, the amount of the hydrogen peroxide is described based on the
concentration of 100%.
The nitrate may include at least one selected from the group consisting of ammonium
nitrate, calcium nitrate, sodium nitrate, magnesium nitrate, and the like, and sodium nitrate is
preferably used.
80% to 95% by weight of the oxidizing agent aqueous solution is contained with respect
to the total weight of the emulsion explosive composition. When the composition ratio of the
oxidizing agent aqueous solution exceeds 95% by weight, a problem in that the emulsion is not
prepared may occur. On the contrary, when the composition ratio of the oxidizing agent
aqueous solution is less than 80% by weight, a problem ofnon-detonation may occur.
In one embodiment of the present disclosure, the emulsion explosive composition may
further contain 0.1% to 10% by weight of an oil thickener. The oil thickener may be contained
by being added to an oil composition. In the above numerical range, 2% to 10% by weight of
the oil thickener is preferably contained, and 3% to 10% by weight of the oil thickener is more
preferably contained.
The oil thickener may include at least one selected from the group consisting of
hydrogenated palm oil, glucamate, cetyl alcohol, polyquarter, and the like.
The emulsion explosive composition of the present disclosure containing the oil
thickener may have a viscosity in a range of 10,000 cP to 300,000 cP, preferably, in the range of
50,000 cP to 200,000 cP, and more preferably, in the range of65,000 cP to 100,000 cP.
In one embodiment of the present disclosure, the emulsifier may include at least one
selected from the group consisting of sorbitan monooleate (SMO), amine salt of polyisobutylene
succinic anhydride (PIBSA), and the like, but is not limited thereto.
The emulsifier preferably includes an emulsifier containing PIBSA amine salt having a
flash point of 100°C or higher, an acid value of7 to 8, and an amine value of40 to 60.
In one embodiment of the present disclosure, the oil may include at least one selected
from the group consisting of fuel oil, oil, and the like.
The fuel oil may include at least one selected from the group consisting of wax, mineral
oil, light oil, and the like. Preferably, carbonaceous fuel oil that is liquefied at a temperature in a
range of50°C to 80°C is used as the fuel oil.
The oil may include at least one selected from among mineral oil, lubricating oil, and the
like. In one embodiment of the present disclosure, the emulsion explosive composition may
further contain plastic micro bubbles (PMBs) or glass micro bubbles (GMBs). 0.1% to 10% by
weight of the PMBs or GMBs may be contained with respect to the total weight of the
composition.
In one embodiment of the present disclosure, the emulsion explosive composition may
further contain KMnO4. 0.0001 to 1% by weight of the KMnO4 may be contained with respect
to the total weight of the composition.
When adding the nitrate to the hydrogen peroxide in the emulsion explosive
composition of the present disclosure, the energy can be increased as follows. In addition, since
the specific gravity of the emulsion is higher than that of an emulsion using only hydrogen
peroxide, a wider range of specific gravity is available depending on the content of a sensitizer.
As a result, the scope of gunpowder energy also broadens, so the power of gunpowder is
selectively available depending on the nature of the applied field.
