液体发射药的玻璃化转变温度及其体积弛豫活化焓

The Glass Transition Temperature and the Activation Enthalpy of Volume Relaxation of Liquid Gun Propellants

用ＤＳＣ测定了三种硝酸羟胺－三乙醇胺硝酸盐－水（ＨＡＮ－ＴＥＡＮ－Ｈ２Ｏ）为主成分的液体发射药的玻璃化转变温度，研究了玻璃化转变温度与升温速率的关系，导出了玻璃化转变时体积弛豫的活化焓的表达式，并计算得到了这种活化焓，为改进预测液体发射药低温粘度的方法打下了基础。

The glass transition temperatures (T g) of three liquid gun propellants (LGP) of the ternary system of hydroxylammonium nitrate triethanolammonium nitrate water (HAN TEAN H 2O) have been measured and the dependence of T g on heating rate has been investigated by means of DSC.An equation for the activation enthalpy of volume relaxation at glass transition was derived and its activation enthalpy was calculated, resulting in an improvement on the method of prediction of viscosity for LGP at low temperature.
