摘　　要：采用模压化学发泡法制备了EPDM/胶粉共混发泡材料。利用均匀实验设计法设计了实验,研究了废旧胶粉和化学发泡剂用量对EPDM发泡材料硫化特性、力学性能的影响,并通过神经网络和遗传算法对实验数据进行处理。结果表明,随着胶粉用量的增加,发泡材料的交联作用和发泡进程均有所减弱,当胶粉用量在20份以下,发泡剂用量在9~12份时,发泡材料的综合性能较好。The EPDM/waste rubber powder microcellular foam was prepared by molding method.The influence of foaming agent（AC）and waste rubber powder by uniform design on the vulcanizing properties and physical properties was investigated.The results showed that,with the content of waste rubber powder increasing,the crosslinking and foaming process of the foam decreased.The foam material possessed better comprehensive performance when the amount of waste rubber powder was under 20 phr and the foaming agent was 9~12phr.
