摘　　要：通过使用阻燃协效剂,实现了护套料在低阻燃剂填充量情况下的高效阻燃,有助于获得集高阻燃、高力学性能和抗开裂性能于一身的无卤阻燃电缆护套料。热重和氧指数测试结果表明,材料的热分解过程得到有效抑制,并且燃烧后可形成结构碳,提高材料的阻燃性能。力学性能测试及扫描电镜结果表明,无机阻燃剂与基体树脂间的界面作用通过阻燃协效剂得到增强,因而具有良好的机械强度和伸长率。抗开裂试验结果直接反映出这种新型低烟无卤阻燃护套料具有良好的抗开裂性能。By making use of flame retardant synergist,sheath material realizes high-efficiency flame retardant in low content of flame retardant filler and gets anti-cracking,high flame retardant and high mechanical properties.TGA and LOI test results demonstrate that thermal degradation process of materials can be restrained.Structural carbon formed in burning process can improve flame retardant property of materials.Mechanical property and SEM test results demonstrate that flame retardant synergist enhances matrix-filler interaction,so sheath materials get excellent tensile strength and elongation at break.Anti-cracking test demonstrate that the new sheath material has excellent anti-cracking property.
