摘要
采用热失重分析仪对偶氮二甲酰胺(AC)及其与氧化锌(ZnO)复配体系的分解特性进行了研究,采用模压发泡法制备了PVC发泡材料,研究了AC/ZnO及邻苯二甲酸二辛酯(DOP)对PVC发泡材料力学性能及体积密度的影响。结果表明:AC/ZnO复配的最佳比例为1∶1,此时最高分解速率温度为173.97℃。添加AC/ZnO质量分数为6%时,发泡材料的力学性能良好,体积密度降至0.67 g/cm^3,在此基础上添加DOP质量分数为10%时,材料的体积密度降至0.44 g/cm^3,但力学性能损失较大。
Decomposition characteristics of azodicarbonamide （AC） and AC/zinc oxide （ZnO） composite system was studied by using thermal gravimetric analyzer, prepared PVC foamed materials by molding foam process. It showed that the optimal proportion of AC/ZnO was 1 ： 1, while the temperature of maximum decomposition rate was 173.97 ℃ o When the contents of AC/ZnO was 6% , the mechanical properties of foamed materials was fine, the volume density was decreased to 0. 67 g/cm3. When the DOP contents was 10% , the volume density was decreased to 0.44 g/cm3 , but the mechanical properties had more loss.
