Abstract

In order to obtain the system of functional agents for 2,4-dinitroanisole（DNAN）-based melt-cast explosives and improve the performance of its charge, Tween 60 and cellulose acetate butyrate（CAB）are chosen as the preferred agents according to the calculated works of adhesion. The influences of functional agents on tensile strength, shear strength, impact sensitivity, friction sensitivity, shock sensitivity and charge density of DNAN 20/HMX 80 melt-cast explosive are analyzed by using Brazil test, static shear test, determination of friction sensitivity-explosion probability method, determination of impact sensitivity-explosion probability method, small scale gap test and hydrostatic weighing method. The results show that, when 1wt% Tween 60 and 1wt% CAB are added in DNAN 20/HMX 80 melt-cast explosive, its tensile strength is increased by 6.25%，10.3% and 47.8% at -40 ℃, 20 ℃ and 60 ℃, respectively; its shear strength are increased by 23.5%，27.8% and 45.1% at -40 ℃, 20 ℃ and 60 ℃,respectively；its friction sensitivity, impact sensitivity and shock sensitivity are decreased by 14.29%, 4.76% and 3.11%, respectively；and its relative density is increased by 0.2%. Therefore, Tween 60 and CAB can be used to improve the mechanical properties and safety performance of DNAN-based melt-cast explosives.
