| 中文摘要: |
| 研制环保低烟无卤阻燃线缆包覆材料。结果表明：主体材料为低密度聚乙烯（LDPE）/乙烯-醋酸乙烯共聚物（EVA）/三元乙丙橡胶（EPDM）（共混比36/54/10）体系，阻燃剂为氢氧化铝/无机填料Create-E/氢氧化镁（并用比60/30/60）体系，相容剂为EVA接枝马来酸酐（EVA-g-MAH）（用量为8份）的线缆包覆材料物理性能、阻燃性能、电性能和环保性能均达到指标要求，成品线缆使用性能良好。 |
| 英文摘要: |
| In this study， the environmentally friendly coating material for low smoke zero halogen (LSZH) cable was developed. The matrix material was a blend of low density polyethylene (LDPE)， ethylene-vinyl acetate copolymer (EVA) and ethylene propylene diene monomer rubber (EPDM) at the blending ratio of 36/54/10. The flame retardant system was hydroxide aluminum/inorganic filler Create-E/magnesium hydroxide with the ratio of 60/30/60.8 parts of maleic anhydride grafted EVA (EVA-g-MAH) were applied as the compatibilizer. The experimental test results on the cable shealthing material showed its physical properties， flame retardant properties and electrical properties reached the application requirements. The coating material was environmentally friendly and the finished cable product showed good performance. |
