To expose the safety of KClO₄-type pyrotechnics composite, seven 50/50/m/n-KClO₄/Al/epoxy resin/graphite mixture systems(m=n=0; m=3, n=0; m=5, n=0; m=5, n=1; m=5, n=2; m=5, n=3; m=5, n=4) known as samples 1^#-7^# in this work were prepared, respectively. The effects of epoxy resin and graphite on the impact sensitivity of KClO₄-type pyrotechnics composite were studied by standard method GJB772A-1997-601.1, TG-DTA and SEM. The results show that the explosion percent of impact sensitivity for samples 1^#-7^# is 0, 60, 76, 40, 12, 2 and 0, respectively. In comparison with sample 1^#, adding epoxy resin in samples 1^# makes the explosion percent of impact sensitivity of samples 2^# and 3^# enhance and with increasing the amount of epoxy resin in samples 3^#, the explosion percent of impact sensitivity increases. In comparison with sample 3^#, the addition of graphite into samples 4^# makes the explosion percent of impact sensitivity of samples 4^#-7^# decreases and with increasing the amount of graphite in samples 3^#, the explosion percent of impact sensitivity decreases in the order 4^#>5^#>6^#>7^#. The reasons of sensitization of epoxy resin and desensitization of graphite to the KClO₄-Al binary system are discussed.
