Problems solved by technology

The root cause lies in the low detonation sensitivity of modified ammonium oil explosives, which is prone to residual guns and rejected blasts.
In our research, we found that the root cause of the low detonation sensitivity of explosives is that the explosives are not resistant to water. Once there is a small amount of water in the blast hole, the detonation wave will automatically extinguish during the propagation and the cannon phenomenon will appear, which will cause the explosives to fail. Poor strength
Modified ammonium oil explosives and expanded ammonium nitrate explosives do not have water resistance and waterproof performance, which is the main reason why they cannot be widely used like emulsion explosives

Abstract

The invention relates to a water resistance vegetable composite oil phase which comprises the following components in percent by mass: 5-30 percent of hydrogenated vegetable fatty acid, 5-20 percent of vegetable wax, 20-50 percent of vegetable oil foot, 5-20 percent of vegetable oil and fat, 20-50 percent of decompressed cerate and 0.5-3 percent of surfactant. The water resistance vegetable composite oil phase is prepared by adopting the following steps of: firstly, heating various components in a single melting tank to the temperature of 75-85 DEG C and melting; and sequentially pumping the components into a reaction kettle through an oil pump according to the proportion requirement after weighted through an electronic scale, stirring, raising the temperature to 105-110 DEG C, starting a vacuum pump for dewatering, filtering, forming and packaging. The invention overcomes the defect of water resistance of the modified ammonium nitrate fuel oil explosive and extruded explosives, and provides a high-quality and low-cost water resistance vegetable composite oil phase used for the modified ammonium nitrate fuel oil explosive and extruded explosives; and the explosives produced by using the composite oil phase have excellent water resistance, and especially the extruded explosives really have excellent water resistance.

Description

technical field [0001] The invention relates to a water-resistant plant matter composite oil phase applied to modified ammonium oil explosives and expanded ammonium nitrate explosives and a preparation method thereof. Background technique [0002] In recent years, my country has forced the elimination of powdered ammonium ladder explosives. Relevant research institutes have successively developed new powdery explosives such as expanded ammonium nitrate explosives and modified ammonium oil explosives by modifying ammonium nitrate and using composite oil phases. Since TNT is canceled in explosives, it is of great significance for improving the intrinsic safety of explosives production, improving production conditions and environmental quality. [0003] However, in the powdery modified ammonium oil explosive composed of ammonium nitrate, composite oil phase, and wood flour, due to the cancellation of the sensitizer simple explosive TNT, compared with the powdery ammonium ladder...
