Embodiment 1

[0018] A kind of civil ammonium nitrate modifier, the parts by weight of each component are as follows:

[0019]

[0020] The above-mentioned modifying agent is a solid particle with a particle diameter not greater than 2.5mm.

[0021] The present invention is an ammonium nitrate modifier for civilian use: take the above-mentioned components and carry out a chemical reaction at 85° C. After the reaction, first dehydrate, then dry, and finally grind into powder.

[0022] The civil ammonium nitrate modifier prepared in this example was tested for hygroscopicity and caking performance, and the results showed that the ammonium nitrate with a water content of 0.15% and the ammonium nitrate modifier was exposed to the air for one month, and the ammonium nitrate was detected The water content is 0.17%. And there is no obvious caking phenomenon.

Embodiment 2

[0024] A kind of civil ammonium nitrate modifier, the parts by weight of each component are as follows:

Abstract

The invention discloses a civil ammonium nitrate modifier, which is composed of the following components in parts by weight: 50 to 70 parts of octadecylamine, 5 to 15 parts of stearate, 15 to 30 parts of diatomite and kaolin, 5 to 15 parts of high aluminum powder, and 20 to 40 parts of phosphoric acid water solution. Stearate and diatomite are scientifically and reasonably added so as to prevent secondary moisture absorption and agglomeration; and high aluminum powder is added at the same time in order to improve the explosion temperature and explosion powder of the explosive. The civil ammonium nitrate modifier has the advantages of reasonable and scientific formula and prominent improvement on the anti-dampness performance and anti-agglomeration performance of industrial ammonium nitrate explosive.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a civil ammonium nitrate modifier. Background technique [0002] Ammonium nitrate is an oxygen-rich substance. Since it was used in industrial explosives in 1867, it has become the main raw material of industrial explosives because of its high oxygen content, high explosive power, low price, and good safety. It is widely used in various industrial explosives such as solid explosives, aqueous explosives, and emulsion explosives. [0003] The obvious defects that ammonium nitrate exists are hygroscopicity and agglomeration, which affect and limit the reliability of the manufacture, storage, transportation and use of ammonium nitrate explosives to a large extent. With the continuous expansion of the application field of industrial ammonium nitrate explosives and the continuous increase in the number of uses, overcoming the moisture absorption and agglomeration defects of ammonium nitr...
