Problems solved by technology

The sulfur content of petrochemical diesel oil is high, and the blast smoke pollutes the environment after blasting, and it is a non-renewable resource
Due to the high cold filter point of ordinary petrochemical diesel oil without additives, it will solidify in the low temperature environment, which limits the use of ammonium oil explosives in Xinjiang, Inner Mongolia and other winter alpine regions
Although diesel oil of No. 10, No. 20, and No. 30 can maintain liquid state at low temperature, the price is relatively expensive
Petrochemical diesel has a low flash point, high volatility, easy to catch fire, and poor transportation and use safety
With the gradual depletion of petroleum resources, the cost of petroleum co-products is getting higher and higher, resulting in the problem of high cost of oil phase raw materials used in ammonium oil explosives

Abstract

The invention discloses an ammonium nitrate-fuel oil explosive and a preparation method thereof. The explosive is characterized by comprising the following components in parts by weight: 78.2 to 94 parts of ammonium nitrate and 2 to 8.3 parts of biodiesel. The explosive also comprises salt sodium chloride and wood powder. The invention further provides a preparation method of the explosive. The provided ammonium nitrate-fuel oil explosive has the characteristics of low cost, environment-friendliness, and safety.

Description

technical field [0001] The invention relates to the field of explosives, in particular to an ammonium oil explosive and a preparation method thereof. Background technique [0002] Ammonium oil explosive is a powdery or granular explosive mechanical mixture mainly composed of ammonium nitrate and fuel oil. The manufacturing process and composition of this explosive are simple, and the cost is low. It is widely used in on-site mixing trucks in mines at home and abroad, especially in Western Europe, North America and Southeast Asia, so that it has become the most important ammonium nitrate explosive. [0003] Fuel oil phase is an important part of ammonium oil explosives. The quality and performance of the fuel oil phase are directly related to the drug state, explosive performance and stability of the ammonium oil explosive. Proper selection of the fuel oil phase can not only improve the explosive performance and storage stability, but also reduce the cost. [0004] The cho...
