Method for preparing boron bead complex for solid propellant, boron bead complex prepared thereby, solid propellant comprising the same

摘要

The present invention comprises the steps of: a) dissolving 5-15 parts by weight of a binder in 40-60 parts by weight of a solvent to prepare a binder solution; b) adding 10 to 30 parts by weight of ammonium chlorate (AP), 10 to 30 parts by weight of boron, and 0.5 to 5 parts by weight of at least one coating agent selected from LiF and silane to the binder solution; c) high-speed stirring of the mixture of step b) at 1200 to 1700 rpm; And d) a method for producing a boron bead complex for a solid propellant comprising a step of removing the solvent, wherein the boron bead complex particles for a solid propellant prepared by the method have a particle diameter of greater than 0 to 2 mm. A method for producing a boron bead complex for a propellant, a boron bead complex prepared thereby, and a solid propellant comprising the boron bead complex are provided.
