摘　　要：探讨了膨胀型阻燃剂和包覆红磷对EPDM/EVM共混胶的阻燃作用及两者之间的协效阻燃作用。结果表明,阻燃剂APP/PER配比为3∶1时阻燃效果最佳,极限氧指数(LOI)可达25.7;包覆红磷单用时对EPDM/EVM共混胶有一定的阻燃作用,但效果不理想;膨胀型阻燃剂与包覆红磷并用时,存在P—N协效阻燃作用。The fire performance and mechanical properties of EPDM/EVM blends containing intumescent flame retardants and encapsulated red phosphorus and their synergism were discussed in this paper.It is shown that the optimal ratio of intumescent flame retardant APP/PER was 3∶1,and the LOI could reach 25.7.The single addition of encapsulated red phosphorus had some degree flame-retardant effect on EPDM /EVM system,and could not meet the requirements in most cases.It was shown by studying the flame-retardant properties and thermal behavior characterization that the P-N synergist effect between intumescent flame retardant and encapsulated red phosphorus did exist.
