1. A method for the preparation of an explosive composition which comprises dispersing with mixing polytetrafluoroethylene resin together with a non-ionic wetting agent in sufficient water to make a substantially homogeneous dispersion containing about 55-65% polytetrafluoroethylene resin solids, adding with mixing the dispersion of said polytetrafluoroethylene resin to a water slurry of a solid explosive capable of being plastic bonded selected from the group consisting of 1,3-diamino-2,4,6-trinitrobenzene, cyclotrimethylenetrinitramine and cyclotetramethylenetetranitramine, slowly adding with agitation to the explosive slurry containing the polytetrafluoroethylene resin a coagulating water-miscible organic solvent selected from the group consisting of methyl alcohol, ethyl alcohol, n-propyl alcohol, isopropyl alcohol and mixtures thereof, and recovering a coagulated bonded explosive, said polytetrafluoroethylene resin amounting to from 2-10% by weight of the explosive composition. |
