Problems solved by technology

[0003] However, the current explosive formula design has poor thermal stability. In deep-hole high-temperature blasting, the high temperature generated by the long-term natural heating of the rock mass by coal will cause the explosive or the initiation system to explode prematurely under the action of heat, threatening the safety of blasting operators. life
Even if accidental thermal explosion is not achieved, high temperature will cause thermal decomposition of industrial explosives, which will reduce the performance of explosives and lead to poor blasting effects; therefore, developing a high-temperature-resistant colloidal emulsion explosive is a technical problem to be solved urgently by those skilled in the art

Description

technical field [0001] The invention relates to an explosive, in particular to a colloidal emulsified explosive resistant to high temperature environment and a preparation method thereof. Background technique [0002] Emulsion explosive is to use the effect of emulsifier to disperse the droplets of oxidant salt solution evenly in the oil-phase continuous medium containing porous substances such as dispersed air bubbles or hollow glass microspheres to form a water-in-oil emulsion-like explosive. , is a new type of industrial explosive developed in the 1970s. In 1969, Blabm in the United States first elaborated the emulsion explosive technology in a relatively comprehensive way. The earliest emulsion explosive was non-detonator sensitive and must be detonated with the help of a relay primer. Later, with the in-depth research on emulsion explosives, the emulsion explosives developed in the later stage also have detonator sensitivity, and have good water resistance, good explosi...
