Abstract

PURPOSE:To obtain the casting type compsn. for explosive which is excellent in flowability and can be cast under a reduced pressure by incorporating a specific ratio of a surfactant into the compsn. of a specific compsn. consisting of cyclotetramethylene tetranitramine, etc., and a specific binder component. CONSTITUTION:The surfactant is further incorporated at 0.1 to 2% into the compsn. consisting of 70 to 90wt.% cyclotetramethylene tetranitramine or cyclotrimethylene trinitramine and 10 to 30% binder component substantially consisting of high-molecular alcohol, isocyanate and plasticizer as its essential components. Cation types, such as [RN<+>(CH3)3]Cl<->, and anion types, such as ROSO3Na, (where R is CnH2n+1, n=12 to 22) are used as the surfactant. The flowability necessary for casting is applied to the compsn. for explosive which is improved in performance by having a high ratio of the explosive components and the casting thereof under a reduced pressure is enabled.

If it exceeds 2 parts by weight, it tends to reduce the performance of the explosive. For example, the polymeric alcohol is polyoxyethylene glycol, the isocyanate is toluylene 2.4 diisocyanate, and the plasticizer is bisdinitropropyl acetal.Also, even if a surfactant is added, the explosive can be manufactured by the conventional casting method.
