Benefits of technology
[0019]In the present invention, since a polymer emulsion is used instead of an organic solvent, a distillation process at a high temperature of 100° C. or more is not required. Accordingly, the manufacturing time is shortened to thus reduce costs, thereby maximizing the efficiency of the process.
[0020]Further, since the process of distilling the organic solvent is not required, there is no need to allocate dead volume in a reactor, which corresponds to about 1/2 of the total volume of the reactor, to prevent the slurry from overflowing when the organic solvent is distilled. Therefore, the production amount per r
Problems solved by technology
Explosions of explosives cause extensive loss of life and tremendous property damage once they occur because there is no time to evacuate.
However, the WS process is disadvantageous in that a distillation process at a high temperature of 10

[0070]1.24 g (0.0043 mol) of sodium dodecyl sulfonate, which was an emulsifier, 156 g (1.217 mol) of butyl acrylate, which was a monomer of a polymer binder, and 52 g (0.52 mol) of ethyl acrylate were added to 800 g of a process water on the basis of a 25-liter batch, and were agitated for 1 hour. Thereafter, 0.52 g (0.0019 mol) of potassium persulfate, which was an initiator, was added at a temperature of about 80 to 90° C., and a polymerization reaction was then performed at a temperature of 75° C. for 5 to 10 hours, thus manufacturing a polymer emulsion (S110). Thereafter, 3600 g of RDX (Hanwha Co., Ltd.) and 80 g of calcium chloride (CaCl2), which was an emulsion breaker, were added to 20000 g of process water in a 25-liter reactor, and were agitated at a temperature of 25° C. for 10 minutes, thus manufacturing a slurry. Thereafter, 400 g of the manufactured polymer emulsion (the amount of the included polymer binder was 80 g) was added to the manufactured slurry to thus form ag...

A method of manufacturing a press polymer-bonded explosive, in which a polymer emulsion is used to maximize the efficiency of a process, and a press polymer-bonded explosive manufactured using the same. The method includes a polymer-emulsion-manufacturing step of mixing a monomer of a polymer binder and an emulsifier with a process water and then adding an initiator to thus manufacture a polymer emulsion using a polymerization reaction, a slurry-manufacturing step of mixing a raw material including an explosive and an emulsion breaker with fresh process water to thus manufacture a slurry, an agglomerated-particle-forming step of adding the manufactured polymer emulsion to the manufactured slurry to thus form agglomerated particles in which a surface of the raw material is coated with the polymer binder, and an agglomerated-particle-obtaining step of collecting the agglomerated particles using filtration and drying the collected agglomerated particles.
Description
CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of Korean Patent Application No. 10-2017-0048444, filed Apr. 14, 2017, which is hereby incorporated by reference in its entirety into this application.BACKGROUND OF THE INVENTION1. Technical Field[0002]The present invention relates to a press polymer-bonded explosive and, more particularly, to a method of manufacturing a press polymer-bonded explosive, in which a polymer emulsion is used to maximize the efficiency of a process, and a press polymer-bonded explosive manufactured using the same.2. Description of Related Art[0003]Explosions of explosives cause extensive loss of life and tremendous property damage once they occur because there is no time to evacuate. For this reason, there has been a need for an insensitive explosive, which is an explosive not causing an explosion reaction in response to unexpected external stimuli such as heat and shocks, and the demand thereof has also increased. Therefore,...
