| Abstract: |
| The influence of heavy metal-salts，metal oxides，organic acids or their salts on the thermal decomposition behaviour of blowing agent AC was studied using a blowing rate tester based on thermodynamics；the dynamically decomposing temperatures and the heat effects of different systems were determined by DSC.The results showed that tribasic lead sulfate，dibasic lead phosphite，lead stearate and citric acid were the fast secondary blowing agents and had a stronger activating effect on blow ing agent AC；zinc oxide was an ideal activating initiator for blowing agent AC and had a better activating effect when 0.1 phr of zinc oxide was used；and stearic acid，barium stearate and sodium citrate were delayed-action secondary blowing agents and had a weaker activating effect on blowing agent AC. |
