摘要

针对出口欧共体市场的机电产品用电线电缆需要符合RoHS指令要求，通过电子束辐照交联工艺研究了以高密度聚乙烯（HDPE）/乙烯醋酸乙烯酯共聚物（EVA）和氢氧化镁（Mg(OH)2）为基体的电缆绝缘材料，通过交联和添加辅助阻燃剂的方法，解决了无卤阻燃剂用量过多使材料性能下降的问题，分析了有关组分含量对性能的影响，确立了可用于实际生产的具有耐温、阻燃、低烟、无卤、可辐照交联的最佳电缆料配方，其主要性能指标达到耐热125℃辐射交联无卤低烟阻燃聚烯烃绝缘料国家标准和出口欧盟的要求。

Abstract

Electromechanical products exported to the EC market for wire and cable applications must meet the requirements of the RoHS. Blends consisting of high density polyethylene (HDPE)/ethylene vinyl acetate copolymer (EVA) and magnesium hydroxide (Mg(OH)2) as a matrix were investigated by electron beam irradiation. The method of cross-linking and adding an auxiliary flame retardant solution overcomes the problem that arises from a high loading of halogen free flame retardant that results in poor material performance. The effects of various components on material performance were analyzed. The established relationship can be used in actual production to provide heat resistance, be flame retardant, low smoke, halogen free and have irradiation cross-linking to optimize cable material formulation. The main performance index meets the national standard of 125℃ heat radiation cross-linking of a low smoke zero halogen flame retardant polyolefin insulation material, as well as related EU requirements.Cited
