Problems solved by technology

Among them, the emulsion explosive has a complicated production process and high water content in the formula, which leads to high risk in the production process, high production cost, and low explosive power; porous granular ammonium oil explosive is an industrial explosive with safe, simple and low-cost production process. However, due to the poor mixing uniformity of the oxidizing agent and the combustible agent in its components, the performance is low and the blasting effect is poor

Embodiment 1

[0019] Example 1: Taking the production of 20 kg of high-performance, low-cost, and environment-friendly porous granular ammonium oil explosives as an example, the mass percentages of each component of the high-performance, low-cost, and environment-friendly porous granular ammonium oil explosives are: porous granular ammonium nitrate (commercially available) 94.5%, Lubricating oil 2%, oleic acid ester 0.5%, potassium nitrate 0.5%, water 2.5%.

[0020] Operation steps: in the first step, mix lubricating oil and oleic acid ester evenly; in the second step, dissolve potassium nitrate in water to form a potassium nitrate aqueous solution with a concentration of 20%; in the third step, add the potassium nitrate aqueous solution prepared in the second step to the first The mixture prepared in the first step is stirred to form a microemulsion lubricating oil; in the fourth step, the microemulsion lubricating oil and porous granular ammonium nitrate are mixed to prepare a high-perfor...

Embodiment 2

[0021] Example 2: Taking the production of 20 kilograms of high-performance, low-cost, and environment-friendly porous granular ammonium oil explosives as an example, the mass percentages of each component of high-performance, low-cost, and environment-friendly porous ammonium oil explosives are: porous granular ammonium nitrate 92%, diesel oil 3%, Polyisobutylene succinamide 0.5%, water 4.5%.

[0022] Operation steps: the first step is to mix non-standard diesel oil and polyisobutylene succinamide; the second step is to add water to the mixture prepared in the first step and stir to form micro-emulsion diesel oil; the third step is to mix micro-emulsion diesel oil and porous granular Ammonium nitrate is mixed to prepare high-performance, low-cost and environment-friendly porous granular ammonium oil explosives. The measured detonation velocity is: 3300m / s, working capacity: 310ml

Abstract

The invention discloses a high-performance low-cost environment-friendly porous granular ammonium nitrate-fuel oil explosive and a preparation method thereof. The high-performance low-cost environment-friendly porous granular ammonium nitrate-fuel oil explosive comprises, by mass: 90 to 97% of porous granular ammonium nitrate, and 3 to 10% of a micro-emulsified fuel oil or emulsified fuel oil. The micro-emulsified fuel oil or the emulsified fuel oil is composed of a fuel oil, an emulsifier and a solvent; the high-performance low-cost environment-friendly porous granular ammonium nitrate-fuel oil explosive is prepared by mixing the micro-emulsified fuel oil or the emulsified fuel oil with porous granular ammonium nitrate. The porous granular ammonium nitrate-fuel oil explosive possesses excellent explosive performance and environmental protection performance, and is low in production cost.

Description

[0001] Technical field [0002] The present invention is a civil explosive manufacturing technology, especially a high -performance, low -cost environmentally friendly multi -porous ammonium explosive and preparation method for mining and engineering blasting. Background technique [0003] It is understood that industrial explosives currently used in mines and engineering blasting are mainly emulsified explosives and porous granium ammonium olite explosives.For example, China Patent No. 96106442.0 revealed an emulsified explosive prepared by a polymer emulsifier for ester; the Chinese Patent No. 98124310.X released a kind of ammonia explosive and its manufacturing process; although they can meet the requirements of the production process,But there are shortcomings.Among them, due to the complex production process and high water content in the formula, the production process has caused high dangerous production process, high production costs, and small explosion power; porous gran...
