| 本文以氯化聚乙烯橡胶(CM)为研究对象,采用偶氮二甲酰胺(AC)为发泡剂,并采用自由发泡法对CM橡胶进行发泡,并通过体视显微镜考察CM自由发泡橡胶的泡孔结构,通过氧指数对CM发泡橡胶的阻燃性能进行表征,研究氢氧化铝、滑石粉及三氧化二锑用量对CM自由发泡橡胶的泡孔结构、发泡密度、阻燃性能的影响。实验结果表明：随着氢氧化铝、滑石粉的用量增加,发泡CM的密度增大,泡孔尺寸变小,均匀性变差,发泡体的氧指数随填料用量增加而不断增大,阻燃性能得到提高。三氧化二锑对CM发泡材料泡孔结构及密度影响不大,但是氧指数提高显著。 |
| 英文摘要: |
| In this study, chlorinated polyethylene rubber(CM) foam materials were prepared by free foaming method, with azodicarbonamideas as blowing agent. The cellular structure of CM foam materials was observed by stereomicroscope, effects of Al(OH)3, Talc and Sb2O3 on the cell structure , foam density and limiting oxygen index of CM foam materials were investigated, results are as follows: the foam density and limiting oxygen index (LOI) increased with the increase of Al(OH)3 or Talc content, and the cell size decreased and the cell structure become uniform. There is nearly no effect on the cell structure and foam density of CM with increasing of Sb2O3, but the flame retardant performance of CM foam increased significantly with a small amount of Sb2O3. |
