| 摘 要： | 用氢氧化镁(MH)和有机蒙脱土(OMMT)作为阻燃剂制备了阻燃线型低密度聚乙烯(LLDPE),研究了氨基硅油(ASO)对阻燃LLDPE力学性能及阻燃性能的影响。通过锥形量热仪(CONE)和热失重分析(TGA)对材料进行了表征。结果表明:ASO提高了阻燃性能和抑烟效果。当ASO用量为2%时,阻燃LLDPE的热释放速率峰值(pHRR)和平均热释放速率(mHRR)分别降低到169.6kW/m2和86.7kW/m2,比加入ASO前下降了20.5%和9.7%;烟产生速率峰值(pSPR)和总生烟量(TSP)分别降低到0.017m2/s和0.4m2。此外,ASO提高了材料的断裂伸长率和冲击强度。

| Abstract: | The non-halogen flame-retarded LLDPE was prepared by taking magnesium hydroxide (MH) and organic montmorillonite (OMMT) as flame retardants.The effects of amino silicone oil (ASO) on the mechanical properties and flame retardancy of LLDPE were studied.The flame-retarded composite were characterized by CONE and TGA.The results show that ASO could improve the flame retardancy and the performance of smoke suppression of LLDPE.The peak heat release rate (pHRR) and mean heat release rate (mHRR) of flame-retarded... |
