Embodiment 1

[0044] This embodiment provides a kind of high-density small-diameter expanded ammonium nitrate industrial explosive, and its preparation method is,

[0045] Preparation of oil-soluble adhesive:

[0046] Heat 0.9kg of vaseline and 2.1kg of glycerin separately, then mix them evenly, and cool to obtain an oil-soluble adhesive.

[0047] Preparation of high-density and small-diameter expanded ammonium nitrate industrial explosives:

[0048]15 kg of solid granular ammonium nitrate and 2 kg of the above-mentioned oil-soluble binder are uniformly mixed to obtain a mixture; the mixture is uniformly mixed with 83 kg of expanded ammonium nitrate explosive to obtain a high-density small-diameter expanded ammonium nitrate industrial explosive.

Embodiment 2

[0050] This embodiment provides a kind of high-density small-diameter modified ammonium oil industrial explosives, the preparation method of which is as follows:

[0051] Preparation of oil-soluble adhesive:

[0052] Heat 6kg of vaseline and 12kg of glycerin separately, then mix them evenly, and cool to obtain an oil-soluble adhesive.

[0053] Preparation of high-density and small-diameter modified ammonium oil industrial explosives:

[0054] Mix 5 kg of solid granular ammonium nitrate and 10 kg of the above-mentioned oil-soluble binder to obtain a mixture; mix the mixture with 95 kg of modified ammonium oil explosive to obtain a high-density small-diameter modified ammonium oil industrial explosive.

Abstract

The invention provides an industrial explosive and a preparation method thereof. The industrial explosive comprises the following raw materials: powdered explosive, oil-soluble binder and granular ammonium nitrate; wherein the oil-soluble binder includes vaseline and glycerin. The oil-soluble binder composed of a mixture of vaseline and glycerin makes the surface of granular ammonium nitrate have good oil absorption and moisture absorption resistance, which can not only prevent explosives from agglomerating, but also be easy to store and stable; and can effectively protect sensitization Hot spots, improve the detonation sensitivity when explosives explode; at the same time, improve the explosive performance of explosives, make the bombardment reaction complete, and reduce toxic gas emissions during blasting.

Description

technical field [0001] The invention relates to the technical field of industrial explosives, in particular to an industrial explosive and a preparation method thereof. Background technique [0002] Industrial explosives, also known as civilian explosives, are widely used in various industries such as coal mine metallurgy, petroleum geology, transportation, hydropower, forestry construction, metal processing, and controlled blasting due to their low cost, simple manufacture, and reliable application. With the continuous development of the economic construction of various countries, the demand for the output of industrial explosives continues to increase. [0003] At present, powdered explosives are one of the most widely used industrial explosives in my country, which are mainly composed of ammonium nitrate, fuel oil and additives through physical mixing of raw materials. Although powdery explosives have strong detonation force and good sensitivity, their density and fluidi...
