[0073] figure 1 is a flowchart illustrating a method of preparing an emulsifier according to the present invention.
[0074] refer to figure 1, according to the present invention, the method of making the above-mentioned emulsifier includes: reacting polyhydric alcohol and fatty acid under the action of a catalyst in an organic solvent (step S1: preparation of polyhydric alcohol fatty acid ester); adding carboxyl modified After the silicone oil has been reacted for a predetermined time, it is filtered and the solvent is removed under reduced pressure (step S2) to obtain an emulsifier.
[0075] In step S1, mix 1-100 parts by weight of polyol, 1-5 parts by weight of catalyst and 1-300 parts by weight of organic solvent, raise the temperature to 100°C-150°C, Then add 1-200 parts by weight of fatty acid dropwise, then continue to heat up to 150°C-180°C, and react for 2 hours-4 hours, so as to obtain a mixture by esterifying polyhydric alcohol and fatty acid. After the reaction ...

[0125] Embodiment 1: Preparation of composite oil phase for emulsion explosive
[0126] Heat 4.5 parts by weight of composite wax (purchased from Sinopec Nanyang Paraffin Wax Fine Chemical Factory) to 120°C to melt, then add 60 parts by weight of 46# engine oil, 8 parts by weight of methyl oleate and 25 parts by weight of prepared 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 emulsified explosives. The content of each component is shown in Table 3, and the corresponding performance results are shown in Table 4.

[0127] Embodiment 2: the preparation of composite oil phase for emulsion explosive
[0128] Heat 2.0 parts by weight of composite wax (purchased from Sinopec Nanyang Paraffin Wax Fine Chemical Factory) to 120°C to melt, then add 60 parts by weight of 46# engine oil, 10 parts by weight of methyl oleate and 25 parts by weight of prepared 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 emulsified 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 verify better the performance of the composite oil phase according to the emulsion explosive of the present invention, use sorbitan oleate (Span 80) and polyisobutylene succinimide polymer emulsifier (T154) to carry out as emulsifier Compared.
