Description
본 발명은 과산화수소 및 질산염 기반의 에멀전 폭약 조성물에 관한 것이다. The present invention relates to emulsion explosive compositions based on hydrogen peroxide and nitrate.
에멀젼폭약은 1960년대 개발되어 현재까지 전 세계적으로 널리 사용되고 있는 폭약이다. 현재 사용되고 있는 에멀젼폭약은 질산암모늄을 기반으로 하며, 이 질산염은 발파 후 필연적으로 유독한 NOx gas를 발생시킨다. 근래에 환경에 대한 관심 증가와 발파공해에 대한 이슈는 NOx gas를 근본적으로 제거할 수 있는 NOx-free 제품의 개발로 이어졌으며, 질산암모늄 대신 과산화수소를 산화제로 사용한 폭약이 개발되었다. Emulsion explosives are explosives that were developed in the 1960s and are still widely used around the world. Emulsion explosives currently in use are based on ammonium nitrate, which inevitably generates toxic NOx gas after blasting. In recent years, increased interest in the environment and issues regarding blast pollution have led to the development of NOx-free products that can fundamentally remove NOx gas, and explosives using hydrogen peroxide as an oxidizing agent instead of ammonium nitrate have been developed.
이후 산화제에 질산염과 과산화수소를 함께 사용한 조성에 대한 연구가 진행되었으며, 이는 과산화수소만 사용한 제품에 비해 비중 범위를 넓게 사용할 수 있어 사용 가능한 에너지 범위가 넓어져 사용 환경에 따라 화약의 위력을 선택적으로 사용 가능하다.Afterwards, research was conducted on a composition using nitrate and hydrogen peroxide together as an oxidizing agent, and this allows the use of a wider range of specific gravity compared to products using only hydrogen peroxide, which broadens the range of usable energy and allows the power of gunpowder to be selectively used depending on the usage environment. do.
또한, 과산화수소만을 산화제로 사용했을 때의 낮은 에너지를 일부 보완 하면서도 기존 질산암모늄 기반 에멀젼보다 NOx gas의 발생을 감소시키는 이점을 가질 수 있다(I. Fullelove, M. Araos & I. Onederra, Detonation performance of novel hydrogen peroxide and nitrate based hybrid explosives(2017)) .In addition, it can have the advantage of reducing the generation of NOx gas compared to existing ammonium nitrate-based emulsions while partially compensating for the low energy when only hydrogen peroxide is used as an oxidizing agent (I. Fullelove, M. Araos & I. Onederra, Detonation performance of novel hydrogen peroxide and nitrate based hybrid explosives(2017)).
그러나, 질산염이 첨가된 과산화수소 기반 에멀젼은 과산화수소의 높은 반응성으로 인해 과산화수소와 질산염이 반응하여 분해가 일어나 O2 gas를 생성하는 self-gassing 반응을 하며, 특히 상기 self-gassing 반응은 30
그러므로, 상기 self-gassing 발생 문제를 해결할 수 있는 기술의 개발이 요구되고 있다. Therefore, there is a need for the development of technology that can solve the self-gassing problem.

과산화수소 및 질산염 기반의 에멀전 폭약 조성물은 과산화수소의 높은 반응성으로 인해 과산화수소와 질산염이 반응하여 분해가 일어나 O2 gas를 생성하는 self-gassing에 의해 안전성 및 안정성이 저하되는 단점을 갖는다. 본 발명은 이러한 self-gassing 문제를 최소화한 특징을 갖는다.Emulsion explosive compositions based on hydrogen peroxide and nitrate have the disadvantage of reduced safety and stability due to self-gassing, which generates O2 gas when hydrogen peroxide and nitrate react and decompose due to the high reactivity of hydrogen peroxide. The present invention has the feature of minimizing this self-gassing problem.

본 발명의 에멀젼 폭약 조성물에서 과산화수소에 질산염을 첨가하는 경우 다음과 같이 에너지를 높일 수 있으며, 에멀젼의 비중이 과산화수소만 사용한 에멀젼에 비해 높기 때문에, sensitizer의 함량에 따라 다양한 비중 범위로 사용할 수 있어 화약의 에너지의 범위도 넓어져서 적용 현장의 성격에 따라 화약의 위력을 선택적으로 사용할 수 있다.When nitrate is added to hydrogen peroxide in the emulsion explosive composition of the present invention, the energy can be increased as follows, and since the specific gravity of the emulsion is higher than that of an emulsion using only hydrogen peroxide, it can be used in various specific gravity ranges depending on the content of the sensitizer, thereby increasing the gunpowder's specific gravity. The range of energy has also expanded, allowing the power of gunpowder to be used selectively depending on the nature of the application site.
