Formula of compound oil phase for emulsion explosive emulsified in static state and sensitized at medium temperature and low temperature

Abstract

A formula of a compound oil phase for an emulsion explosive emulsified in a static state and sensitized at the medium-low temperature comprises wax substances, a compound emulsifier and an additive in the mass ratio being (61%-65%): (38.5%-34%): (0.5%-1%), and the compound oil phase is generated by mixing the wax substances, the compound emulsifier and the additive; the wax substances are mainly petroleum by-products and have the indexes as follows: the kinematic viscosity is 6-10 mm<2> / s (at the temperature of 100 DEG C), the oil content is 20%-35%, the drip melting point is 50-70 DEG C, and the flash point is higher than or equal to 170 DEG C; the compound emulsifier is prepared after a polymeric surfactant meeting the standard infrared spectrogram curve is added to an sp-80 emulsifier, the content of glycan in the sp-80 emulsifier is smaller than or equal to 0.1%, the dynamic viscosity is 1,050-1,150 mpa.s (at the temperature of 40 DEG C), the hydroxyl value ranges from 240 mg KOH / g to 270 mg KOH / g, and the acid value is smaller than or equal to 4.0 mg KOH / g; the kinematic viscosity of the compound oil phase is 12.5-17 mm<2> / s (at the temperature of 100 DEG C), the oil content is 50%-65%, the drip melting point is 50-65 DEG C, the flash point is higher than or equal to 200 DEG C, and the HLB (hydrophile-lipophile balance) value is 3-6; the additive is a cosurfactant. The formula has the advantages as follows: no oil phase materials are required to be added, and all performance indexes of the produced emulsion explosive can completely meet the national standard.

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 medium and low temperature sensitized emulsified explosives. Background technique [0002] In recent years, 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 using emulsifier emulsification and medium-low temperature sensitization. When the static emulsification high-temperature sensitization process technology is used, the sensitization temperature is 80-90°C. Because of the high sensitization temperature, there is a great safety risk. Many domestic manufacturers and scientific research institutions adopt static emulsification medium and low temperature online sensitization process to varying degrees. The medium temperature sensitization temperature is 60-70°C,...
