摘要
研究了ＰＥ、ＥＶＡ、ＥＰＤＭ、ＥＥＡ和它们共混物的辐射交联，选用三水合氢氧化铝和红磷作阻燃剂制备辐射交联无卤阻燃聚烯烃复合材料。实验结果表明，辐射交联不仅可改善材料的力学性能，而且可克服熔滴现象，提高氧指数，是一种有效的阻燃新技术。所获材料的氧指数为３１，抗张强度９．９ＭＰａ，断裂伸长率为２００％，可在电线电缆工业中推广应用。
JZ)〗 The radiation crosslinking of PE, EVA, EPDM, EEA and their blends has been studied A non-halogen flame retardant polyolefin complex has been prepared with aluminum tri-hydrate (ATH) and red phosphor as flame retardant The experimental results show that radiation crosslinking can not only improve mechanical properties of the material but also increase its oxygen index (O I) thus the melt drop phenomenon disappears The new flame retardant polyolefin thus prepared, with a limiting oxygen index of 31, a tensile strength of 9 9MPa and an “elongation at break” of 200%, can therefore be applied to the electric wire and cable industry
