Embodiment 1

[0025] Put paraffin wax 4, 70# microcrystalline wax 8, beeswax 20, 30# engine oil 5, vaseline 20, rosin 8, and octadecyl primary amine 15 in parts by mass into a wax melting tank, heat up to dissolve and melt; heating temperature is 85°C, The temperature was maintained for 60 minutes to obtain a molten mixture. Pump the melted mixture into a blending kettle equipped with a water-in-oil emulsifier to keep warm and stir at a temperature of 85°C for 10 minutes to obtain a blend. The water-in-oil emulsifier is dioleic acid amido diacrylate sorbitan ethylenediamine, and its mass part is 20. The concoction is put into a solidification tank for solidification and molding to obtain an easily emulsifiable composite oil phase for emulsion explosives. The interfacial tension between the composite oil phase and the ammonium nitrate solution is low, and the interfacial tension is 2.05mN / m.

Embodiment 2

[0028] Example 2: Put paraffin wax 10, 75# microcrystalline wax 2, beeswax 3, 30# engine oil 15, vaseline 10, asphalt 5, put them into the paraffin tank, heat up to melt and melt; heating temperature is 115°C, keep warm for 120 minutes, A molten mixture was obtained. Pump the melted mixture into a blending kettle equipped with a water-in-oil emulsifier to keep warm and stir at a keep temperature of 110°C for 30 minutes to obtain a blend. The water-in-oil emulsifier is dioleic acid amido diacrylate sorbitanyl ethylenediamine, and its mass part is 55%. The concoction is put into a solidification tank for solidification and molding to obtain an easily emulsifiable composite oil phase for emulsion explosives. The interfacial tension between the composite oil phase and the water-soluble ammonium nitrate is low, and the interfacial tension is 1.15mN / m.

Embodiment 3

[0031] Embodiment 3: put paraffin wax 7, 85# microcrystalline wax 5, beeswax 10, 50# machine oil 9, vaseline 13, asphalt 10, rosin 4, octadecyl primary amine 8 into the paraffin tank, heat up and melt; The temperature was 105°C and the temperature was maintained for 100 minutes to obtain a molten mixture. Pump the melted mixture into a blending kettle equipped with a water-in-oil emulsifier to keep warm and stir at a temperature of 95°C for 20 minutes to obtain a blend. The water-in-oil emulsifier is dioleic acid amido diacrylate sorbitan ethylenediamine, and its mass part is 34. The concoction is put into a solidification tank for solidification and molding to obtain an easily emulsifiable composite oil phase for emulsion explosives. The interfacial tension between the composite oil phase and the ammonium nitrate solution is low, and the interfacial tension is 0.67mN / m.

Abstract

The invention relates to an easily-emulsified compound oil phase for emulsion explosives and a preparation method. The compound oil phase comprises the following substances by mass: 4-10 parts of paraffin, 2-8 parts of microcrystalline wax, 3-20 parts of beeswax, 5-15 parts of machine oil, 10-20 parts of Vaseline, 0-10 parts of asphalt, 0-8 parts of rosin, 0-15 parts of octadecylamine, and 20-55 parts of a water-in-oil emulsifier, wherein the water-in-oil emulsifier is bisoleamide bissorbic acrylate ethanediamine. The preparation method of the compound oil phase comprises steps of melting, blending, curing and cartonning. Compared with the prior art, the oil phase material of the invention matches the emulsifier more reasonably, which significantly reduces the interfacial tension between the compound oil phase and an ammonium nitrate aqueous solution. When the emulsification effect is identical, the rotating speed of an emulsifying machine is decreased greatly, and the emulsification time is shortened; When the productivity is the same, the pressure of a static mixer pipeline is decreased significantly. Substrates prepared by the compound oil phase have storage time of up to 24 months; the explosive storage time is up to 18 months; and the explosion performance of explosives meets the national standard GB/T18095-2000.

Description

technical field [0001] The invention relates to the field of industrial explosives, in particular to an emulsifiable composite oil phase for emulsion explosives and a preparation method thereof. Background technique [0002] The composite oil phase is the overall compound of the combustible components used in the manufacture of emulsion explosives. This product is not only beneficial to improve the overall performance of the emulsion explosives, but also can effectively avoid the responsibility and The reason is unclear, and it is a product form that explosives manufacturers are willing to accept. There are many reports on the composite oil phase material for emulsion explosives, such as the Chinese patent publication number is CN102584501A, and the patent title is "a special composite oil phase for emulsion explosives and its preparation method"; the Chinese patent publication number is CN101560128A, and the patent title is " Composite oil phase for emulsion explosives and...
