Formula of composite oil phase for static emulsified and high-temperature sensitized emulsified explosive

Abstract

The invention provides a formula of a composite oil phase for static emulsified and high-temperature sensitized emulsified explosive. The formula comprises a wax substance and a composite emulsifying agent based on the weight ratio from 7: 3 to 3: 2; the wax substance and the composite emulsifying agent are mixed to generate the composite oil phase; the wax substance takes petroleum byproducts as the major, and the indexes of the wax substance is that the kinematic viscosity is 6 to 15 mm<2> / s (100 DEG C), the oil content is 20 to 50%, the dropping-melting point is 50 to 75 DEG C, and the flash point is more than 170 DEG C; the composite emulsifying agent is prepared by adding a high molecular surfactant which meets an infrared spectrum curve to an sp-80 emulsifying agent; the glycan content of the sp-80 emulsifying agent is not greater than 0.1%, the kinematic viscosity is 800 to 1000mpa.s (40 DEG C), the hydroxyl value is between 240 to 270mgKOH / g, and the acid value is not greater than 5.0mgKOH / g; the hydroxyl value of the composite oil phase is 8 to 12mm<2> / s (100 DEG C), the oil content is 30 to 60%, the dropping-melting point is 60 to 70 DEG C, and the flash point is more than 200 DEG C.

Description

technical field [0001] The invention relates to a formula of oil phase, in particular to a formula of composite oil phase for static emulsified high temperature sensitized emulsified explosive. Background technique [0002] At present, domestic explosives manufacturers' emulsion explosive production lines are gradually introducing foreign static emulsification and high-temperature sensitization technologies, and are gradually eliminating the old process of emulsification and low-temperature sensitization using emulsifiers. Compared with the medium and low temperature sensitization process, there is a big difference between the high speed shear emulsification of the emulsifier. In addition to the process, the oil phase material of the raw material also has a large difference. The quality of the oil phase material determines the quality of the emulsified matrix of the process and the quality of the performance of the sensitized explosive. The quality of the explosive performan...
