To adjust the combustion performances of low flame temperature and low burning rate propellants, some catalysts, shch as lead salts, copper salts, carbon black and assistant plasticizer were appended into four low buring rate formulations, whose theoretical flame temperature ranged from 900K to 1700 K, and the function of the catalysts and their additive amount were tested. The results show that those usual catalysts can also work upon low flame temperature and low burning rate DB propellants. The variety of catalysts have different effects on burning rate and pressure exponent, and the combined catalysts can improve the combustion performance obviously. Besides, assistant plasticizer can also affect the combustion performance.

The combustion performance, thermal decomposition, and quenched surface appearance and element distribution of double-base (DB) propellant containing general lead and copper salt catalysts with low burning rate and low flame temperature were investigated. The following experimental phenomena were observed: (1) the elements distribution of quenched samples surface were not uniform, and element C and catalysts existed accumulation to some degree; (2) the quenched surfaces of samples containing catalysts appeared different balls, and different catalysts formed the balls with different diameter distribution,the main compositions of the balls were Pb elements, and the others were small amount of other elements and these balls connected to form long chain and short branch one another; (3) the uncombustion surfaces of samples with or without catalysts had no balls. The results indicated that general lead and copper salt catalysts used in common DB propellants also had catalytic effect on DB propellant with low burning rate and low flame temperature,and also have great effects on thermal decomposition.
