Abstract

The invention provides a composite oil phase for an emulsion explosive for solving the drawbacks of oil phases, which has the advantages of stable quality, simple production and low cost. The emulsion explosive has the advantages of high detonation sensitivity, stable explosion velocity, easy charging and few cartridge igniters. The invention adopts a technical proposal that the oil phase is mixed by using the following raw materials by weight percentage: 29 to 32 percent of span-80, 3.2 to 3.4 percent of polymer emulsifier, 58 to 61 percent of compound wax, 3.1 to 3.5 percent of polyethylene wax and 3.1 to 3.5 percent of No.70 microcrystalline wax.

Description

technical field [0001] The invention relates to an oil phase for emulsified explosives. Background technique [0002] At present, the oil phase materials used for emulsion explosives are as follows by weight percentage: 36% to 38% for Span-80, 40% to 46% for composite wax, 4% to 6% for No. 56 wax, and 3.1% for No. 70 microcrystalline wax 3.5%. It has the following disadvantages: ① high cost, ② unstable quality, ③ complex process for producing explosives in use; ④ the prepared emulsion explosive is not easy to charge and has many burst tubes. Contents of the invention [0003] The invention provides a compound oil phase specially used for emulsion explosives to solve the shortage of the existing oil phase, and has the advantages of stable quality, simple production and low cost. The produced emulsion explosive has good detonation sensitivity, stable detonation velocity, easy charge, Tube less. [0004] The technical scheme of the present invention is: special composite o...
