Embodiment 1

[0026] The preparation of embodiment 1 modifying agent of the present invention

[0027] Table 1 formula (kg)

[0028]

[0029] making process:

[0030] Preparation of octadecylamine phosphate: weigh octadecylamine and emulsifier according to the weight ratio shown in Table 1, pour into the neutralization tank and melt to 80-85°C, start the stirrer, and slowly add the 85% The phosphoric acid is neutralized for 60 to 90 minutes, and the material is sent to the drying plant

[0031] Dry the room until the water content is below 0.5%, then cool it for later use. (Remarks: This reaction is an exothermic reaction, and the speed of adding phosphoric acid should be slow. If 20 kg of phosphoric acid is added, the feeding time should be controlled within 10 to 15 minutes. A large amount of foam will be generated and a large amount of heat will be released during the reaction. and steam, after 15-20 minutes, the product turns into a salt-like paste, and then it is cut out, and it ...

Embodiment 2

[0037] Embodiment 2 Preparation of modifying agent of the present invention

[0038] Table 2 formula (kg)

[0039] Numbering

[0040] Preparation process: According to the weight ratio shown in Table 2, octadecylamine and stearic acid are completely melted by steam heating, then neutralized by adding phosphoric acid, and continuously stirred, then triethanolamine is added, and the reactant is discharged after solidification. Drying; after drying, add ball mill, sodium lauryl sulfate and active soil dispersant for ball milling and sieving.

Embodiment 3

[0041] The preparation of embodiment 3 explosives

[0042] After the ammonium nitrate is coarsely crushed, it is finely crushed and dried by adding the ammonium nitrate at 90-110°C, and the modifier of the present invention (prepared by Example 1-2, number 1-10) is added to modify and mix evenly, and then to the In the first process, the oil phase material and combustible agent (loose agent) are added according to the conventional method to prepare explosives after cooling, and the performance comparison of the prepared explosives is shown in Table 3.

Abstract

The invention relates to an ammonium nitrate modifier and a preparation method thereof, belonging to the field of civil blasting. It is prepared from raw materials containing the following weight proportions: 45-74 parts of octadecylamine phosphate, 1-15 parts of lubricant, 14-40 parts of dispersant and 3-15 parts of surface active agent. According to this weight ratio, 2-8 parts of thickener can also be added. The ammonium nitrate modifier of the present invention improves the overall performance of the modified ammonium nitrate explosives by reducing the activation energy of ammonium nitrate, provides industrial "monosodium glutamate" for ammonium nitrate explosives, and reduces the production cost of explosives compared with the prior art , the charge density is increased, the stability of the explosive is improved, and the explosive power is large, which meets the needs of the development of the ammonium nitrate explosive industry.

Description

technical field [0001] The invention relates to an ammonium nitrate modifier and a preparation method thereof, belonging to the field of civil blasting. Background technique [0002] Civilian blasting equipment requires low cost and high power. Over the years, in order to improve product performance and reduce production costs, the civil explosive industry has made a lot of efforts, including the development and production of 2# rock ammonium ladder oil explosives, and the development and production of 4# rock ammonium ladder oil explosives to reduce TNT. The main target, supplemented by fuel oil and other high-heat substances as combustible agent (ie reductant), develops towards the direction of few ladders and no ladders, and then reaches the ladder-containing explosive that cancels TNT. Starting from the main raw material of explosives - ammonium nitrate, the modification can not only meet the explosive performance indicators of explosives, but also achieve explosives wi...
