Method for preparing emulsion explosive by high-temperature sensitization

The invention relates to a method for preparing an emulsion explosive by high-temperature sensitization. The method comprises the following steps: preparing a water phase, preparing an oil phase, emulsifying, sensitizing, charging and cooling. The emulsion explosive comprises the following raw materials: ammonium nitrate, sodium nitrate, urea, water, a composite oil phase, an emulsifier, a foamer and an accelerant, wherein the accelerant is a potassium biphthalate buffer solution with the pH value of 5.5, a potassium dihydrogen phosphate buffer solution with the pH value of 4.5, a potassium tartrate buffer solution with the pH value of 3.5 or a potassium tetroxalate buffer solution with the pH value of 1.0; the sensitizing process comprises the following sub-steps: uniformly mixing the accelerant with the foamer to obtain a mixture, adding the mixture into a latex matrix with the temperature of 85-110 DEG C, uniformly mixing, and sensitizing for 0.5-10 minutes. According to the method, the raw material-accelerant is wide in source, low in cost and nontoxic, and the pH value of the explosive is increased, and the explosive performance can be improved; the sensitizing process is simple, quick and free of aftereffect, the production process is simplified, the cost is reduced, and the energy consumption is reduced.

Environment-friendly water-based fire extinguishing agent for fire protection

The invention belongs to the technical field of fire-fighting foam, and discloses a fire-fighting environment-friendly water-based fire extinguishing agent. The fire extinguishing agent is prepared from the following raw materials in percentage by weight: 15 to 40 percent of fatty acid amide, 5 to 10 percent of phosphate, 5 to 10 percent of foaming agent, 3 to 5 percent of fatty alcohol, 1 to 3 percent of pH regulator, 0.5 to 0.8 percent of preservative, 0.2 to 0.5 percent of stabilizer, 10 to 15 percent of organic solvent and the balance of water. According to the invention, fatty acid amide is used as a main surfactant and cooperates with other assistants, so the prepared fire extinguishing agent has the advantages of low interfacial tension, high wettability and high foaming and fire extinguishing speed; phosphate is added into the fire extinguishing agent, so that the flame retardance can be improved, the wettability of the system is improved, and the foaming property and the fire extinguishing property of the system are promoted to a certain extent; the addition of the fatty alcohol can increase the emulsifying property of the system, reduce the interfacial tension of oil and water and reduce the height of an emulsifying layer of mixed oil and water; the emulsifying effect is promoted by controlling the addition amount of the fatty alcohol, but the height of an oil-water mixing layer is not increased, and fire extinguishment and field treatment after fire extinguishment are facilitated.
