Abstract: 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.

Abstract: The present invention relates to a catalyst-supporting organic-inorganic hybrid composite particle, and more particularly, to a technique of adjusting a desired pot life and curing speed by preparing a catalyst-supporting organic-inorganic hybrid composite particle by adding a catalyst for polyurethane reaction to a catalyst-supporting particle prepared by stirring an alkoxy silane-functionalized polyurethane precursor and the tetraethyl orthosilicate for a certain period of time and mixing them, and adjusting an initiation rate for polyurethane polymerization through the prepared catalyst-supporting organic-inorganic hybrid composite particle.
