preparation example Construction

[0021] The preparation method of mixed dispersant is as follows:

[0022] Add magnesium nitrate to the water and stir for 5min (stirring speed 200r / min), until the magnesium nitrate is completely dissolved, then add polyethylene glycol and stir for 2min (stirring speed 200r / min), until the polyethylene glycol is completely dissolved, then add the diffusing agent NNO, Stir while adding (stirring speed 200r / min), until the diffusion agent NNO is completely dissolved, add sodium carboxymethyl cellulose, stir while adding (stirring speed 200r / min), until sodium carboxymethyl cellulose is completely dissolved, that is A dispersant must be mixed.

Embodiment 1

[0024] Prepare mixed dispersant 1 according to the above-mentioned preparation method, the weight percent of raw material is as follows:

[0025] 10% polyethylene glycol; 10% magnesium nitrate; 2% dispersant NNO; 3% sodium carboxymethyl cellulose; 75% water.

Embodiment 2

[0027] Prepare mixed dispersant 2 according to the above-mentioned preparation method, the weight percent of raw material is as follows:

[0028] Polyethylene glycol 5%; magnesium nitrate 5%; dispersant NNO 0.5%; sodium carboxymethylcellulose 0.5%; water 89%.

Abstract

The invention discloses a mixed dispersing agent for a modified ammonium nitrate fuel oil explosive and a preparation method of the mixed dispersing agent. The mixed dispersing agent for the modified ammonium nitrate fuel oil explosive comprises the following raw materials in percentage by weight: 5-15% of polyethylene glycol, 5-15% of magnesium nitrate, 0.5-5% of a dispersing agent NNO, 0.5-5% of sodium carboxymethyl cellulose, and the balance of water. The preparation method comprises the steps of sequentially adding magnesium nitrate, polyethylene glycol, a dispersing agent NNO and sodium carboxymethyl cellulose into water, and completely dissolving, wherein the next raw material is added when the previous raw material is completely dissolved in water. The method can effectively improve the phenomenon that the modified ammonium nitrate fuel oil explosive is non-uniform in expansion and easy to cake and harden in high-temperature and humid seasons.

Description

technical field [0001] The invention relates to a mixed dispersant for modified ammonium oil explosives and a preparation method thereof, belonging to the technical field of modified ammonium oil explosives production. Background technique [0002] Modified ammonium oil explosive is a new type of mixed stepless powder ammonium oil explosive developed on the basis of ammonium oil explosive. The main components are ammonium nitrate (oxidant), composite oil phase (reductant), agent is also a density regulator) and additives, the production process is simple and the cost is low. But the density of modified ammonium oil explosives is small, and the fluidity and water resistance are poor. In the Sichuan Basin area where the applicant is located, large packages of products tend to agglomerate and harden due to high temperature and humidity in summer. [0003] At present, in the production of modified ammonium oil explosives, dispersants are usually not added, or a single dispersa...
