（1）将高密度聚乙烯、乙烯-醋酸乙烯共聚物、乙烯-四氟乙烯共聚物、甲基丙烯酸甲酯-丙烯腈-丁二烯-苯乙烯共聚物和乙烯-醋酸乙烯共聚物接枝马来酸酐投入到捏合机内，捏合3-5min，然后加入氢氧化镁、红磷、硼酸锌、乙撑双硬脂酰胺、活性氧化铝和环氧大豆油，捏合2-4min，待料温升至75-85℃，再加入余下原料，捏合4-6min，待料温升至90-100℃时，将料卸到冷却混合机中冷却，降温至45℃以下时出料；　
（2）将上述混料投入双螺杆挤出机中挤出造粒，双螺杆挤出机各区的加工温度分别为：1区165-175℃、2区170-180℃、3区185-195℃、4区175-185℃，机头180-190℃；挤出机螺杆转速30-40r/min；
（3）粒料经筛选磁选、计量后包装即为成品。
