摘要
Abstract
The effects of lead salt burning-rate catalyst ( LBC) on thermal decomposition procedures of key constituents of CAP propellants,such as ammonium perchlorate (AP) ,cyclotetramethylenetetranitramine (HMX) and GAP binder system, were investigated respectively by means of thermogravimetric (TG) analysis and differential scanning calorimeter ( DSC) methods with linear heating-up mode. The characteristic values of thermal decomposition and weight loss for ( AP.AP/LBC) , (HMX,HMX/LBC) and (GAP binder,GAP binder/LBC) were determined and compared. The research results verify that addition of the LBC leads to the decrease of the high-temperature decomposition temperature and the increase of the exothermic reaction for AP within low-temperature region, which indicates that the LBC can conduct remarkable catalysis on thermal decomposition procedure of AP. The addition of LBC has an obvious influence on exothermic quantity of nitrate esters and pure GAP. But the case is not visible for that of HMX.关键词
