Formula of HMX-TNT-based melt-cast explosive viscosity reducer

The invention discloses a formula of an HMX-TNT-based melt-cast explosive viscosity reducer. The formula comprises naphthalene, stearic acid and octadecanol which are mixed according to the mass ratioof 1:2:(0.5-2), the formula of the viscosity reducer is applied to a 5 [mu]m superfine HMX/TNTmelt-cast explosive system, the mass ratio of the viscosity reducer is 2%, and when the mass ratio of HMXin the system is 50%, the viscosity of the system can be reduced by 21%; when the mass ratio of HMX in the system is 55%, the viscosity of the system can be reduced by 27%; when the mass ratio of HMXin the system is 60%, the viscosity of the system can be reduced by 33%; when the mass ratio of HMX in the system is 65%, the viscosity of the system can be reduced by 37%; and when the mass ratio ofHMX in the system is 70%, the viscosity of the system can be reduced by 42%. The viscosity reducer is simple to prepare and operate, safe, reliable, low in toxicity and low in cost, can effectively reduce the viscosity of the H
