preparation example Construction

[0073] figure 1 is a flow chart illustrating a method of preparing an emulsifier according to the present invention.

[0074] refer to figure 1, the method for producing the above-mentioned emulsifier according to the present invention comprises: reacting polyol and fatty acid under the action of a catalyst in an organic solvent (step S1: the preparation of polyol fatty acid ester); adding carboxyl modification to the mixture After the silicone oil is reacted for a predetermined time, the solvent is removed by filtration and reduced pressure (step S2), thereby obtaining an emulsifier.

[0075] In step S1, 1-100 parts by weight of polyol, 1-5 parts by weight of catalyst and 1-300 parts by weight of organic solvent are mixed, and the temperature is raised to 100 ℃-150 ℃, Subsequently, 1-200 parts by weight of fatty acid is added dropwise, and then the temperature is continued to rise to 150° C. to 180° C. for 2 hours to 4 hours to obtain a mixture by esterification of polyol a...

[0125] Example 1: Preparation of composite oil phase for emulsion explosives

[0126] 4.5 parts by weight of composite wax (purchased from Sinopec Nanyang Paraffin Fine Chemical Plant) was heated to 120° C. to melt, and then 60 parts by weight of 46# engine oil, 8 parts by weight of methyl oleate and 25 parts by weight were added successively. The silicone emulsifier prepared in Example 1 was stirred at 75° C. for 2 hours until uniform, and finally 2.5 parts by weight of zinc stearate was added, stirred and cooled to obtain a composite oil phase for emulsion explosives. The content of each component is shown in Table 3, and the corresponding performance results are shown in Table 4.

[0127] Example 2: Preparation of composite oil phase for emulsion explosives

[0128] 2.0 parts by weight of composite wax (purchased from Sinopec Nanyang Paraffin Fine Chemical Plant) was heated to 120° C. to melt, and then 60 parts by weight of 46# engine oil, 10 parts by weight of methyl oleate and 25 parts by weight were added successively. The silicone emulsifier prepared in Example 2 was stirred at 80° C. for 2 hours until uniform, and finally 3.0 parts by weight of zinc stearate was added, stirred and cooled to obtain a composite oil phase for emulsion explosives. The content of each component is shown in Table 3, and the corresponding performance results are shown in Table 4.

[0129] In order to better verify the performance of the composite oil phase for emulsion explosives according to the present invention, sorbitan oleate (Span 80) and polyisobutylene succinimide polymer emulsifier (T154) were used as emulsifiers. Compared.

Abstract

The invention discloses a composite oil phase for emulsified explosive and a preparation method of the composite oil phase as well as an emulsion matrix and the emulsified explosive. The composite oilphase for the emulsified explosive is prepared from the following components in parts by weight: 1 to 30 parts of organosilicon emulsifier, 3 to 60 parts of base oil, 1 to 10 parts of fatty acid ester, 0 to 5 parts of viscosity modifier and 0 to 3 parts of an oil phase stabilizer. According to the composite oil phase for the emulsified explosive, disclosed by the invention, all the components have good compatibility, and the viscosity of the oil phase can be adjusted according to use requirements; in addition, the composite oil phase has the advantages of higher hydrophobicity, high and low temperature resistance and better flowability at normal temperature.

Description

technical field [0001] The invention belongs to the field of emulsion explosive compositions, in particular to a composite oil phase for emulsion explosives and a preparation method thereof, an emulsion matrix and an emulsion explosive. Background technique [0002] Emulsion explosive is a W / O type industrial explosive prepared by emulsification technology under the action of emulsifier, with ammonium nitrate aqueous solution as dispersed phase and oil phase as continuous phase. Because of its good water resistance, storage stability and detonation performance Widely recognized at home and abroad, the output has grown rapidly in recent years. The essence of the emulsion explosive is that the ammonium nitrate salt solution is emulsified by the emulsifier to form internal phase particles, which are tightly wrapped by the oil phase in the oil layer to form a stable emulsion. In actual production, in order to enhance the convenience and safety of production operations, emulsifi...
