Abstract
Proposed is 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. The emulsion explosive composition can effectively solve self-gassing problems caused by a reaction between hydrogen peroxide and nitrate.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . An emulsion explosive composition comprising:
80% to 95% by weight of an oxidizing agent aqueous solution comprising hydrogen peroxide, nitrate, and diethylenetriamine penta(methylene phosphonic acid) (DTPMPA); to 10% by weight of an emulsifier; and 2% to 15% by weight of an oil.
2 . The composition of claim 1 , wherein the oxidizing agent aqueous solution comprises:
10% to 45% by weight of the hydrogen peroxide; 10% to 50% by weight of the nitrate; to 15% by weight of the DTPMPA; and 10% to 45% by weight of water.
3 . The composition of claim 1 , wherein the nitrate comprises at least one selected from the group consisting of ammonium nitrate, calcium nitrate, sodium nitrate, and magnesium nitrate.
4 . The composition of claim 1 , further comprising 0.1% to 10% by weight of an oil thickener comprising at least one selected from the group consisting of hydrogenated palm oil, glucamate, cetyl alcohol, and polyquarter.
5 . The composition of claim 1 , further comprising a plastic micro bubble (PMB), a glass micro bubble (GMB), or KMnO 4 .Cited by (0)
