环保阻燃线缆用的挤出耐高温TPE材料
技术领域：本发明属于聚合物改性和加工生产领域，具体涉及一种环保阻燃线缆用的挤出耐高温TPE材料。
技术背景：目前，线缆用的材料基本都是挤出成型的，材料大多采用两种，一种是传统PVC材料，它应用范围广、生产工艺简单、每年的需求量都在大幅度增长，但是长期使用温度范围在80℃以内，且耐低温性差，易开裂，低温时表面硬度变化较大，燃烧时产生有毒气体，使其应用范围受到限制另一种是阻燃EVA材料，使用温度范围在80℃以内，但其强度较低，耐低温性差，不耐折弯。
发明内容：本发明的目的是提供一种生产工艺简单，可重复利用，强度高，耐低温性好，耐高温可达120度的环保阻燃线缆用挤出耐高温TPE材料。
本发明的技术方案是：一种环保阻燃线缆用的挤出耐高温TPE材料，其特征是由以下组分按重量份组成：SEBS50-100、白油50-150、聚丙烯100-200、环保阻燃剂200-300、稳定剂0.4-0.8。其中，所述白油为石腊油或环烷油或二者的混合物；所述的稳定剂是主抗氧剂1010和辅助抗氧剂168 1∶1的混合物；所述的环保阻燃剂是主阻燃剂十溴二苯乙烷和辅助阻燃剂Sb2O3 2∶1的混合物。
加工方法为：在50-80℃的条件下，先将白油和SEBS在搅拌机内慢速混合20-30分钟后，再与其他的原料助剂一起混合20-30分钟，然后加入双螺杆挤出机中，经熔融挤出、冷却、造粒、包装成品即可。其中双螺杆挤出机的螺筒内温度为：一区170-180℃，二区180-190℃，三区180-190℃，四区180-190℃，五区180-190℃，六区180-190℃，七区180-190℃，八区180-190℃，机头180-190℃，双螺杆挤出机转速为100-400转/分。
本发明最佳的技术方案是：一种环保阻燃线缆用的挤出耐高温TPE材料，其特征是由以下组分按重量份组成：SEBS75、白油150、聚丙烯150、环保阻燃剂250、稳定剂0.6。其中，所述白油为石腊油或环烷油或二者的混合物；所述的稳定剂是主抗氧剂1010和辅助抗氧剂168 1∶1的混合物；所述的环保阻燃剂是主阻燃剂十溴二苯乙烷和辅助阻燃剂Sb203 2∶1的混合物。
加工方法为：在50℃-80℃的条件下，先将白油和SEBS在搅拌机内慢速混合20-30分钟后，再与其他的原料助剂一起混合20-30分钟，然后加入双螺杆挤出机中，经熔融挤出、冷却、造粒、包装成品即可。其中双螺杆挤出机的螺筒内温度为：一区170-180℃，二区180-190℃，三区180-190℃，四区180-190℃，五区180-190℃，六区180-190℃，七区180-190℃，八区180-190℃，机头180-190℃，双螺杆挤出机转速为100-400转/分。
本发明的有益效果：采用了超高分子量的SEBS，提高了材料的耐高温性，使新的共聚物在高温下的弹性和高温下的压变性能都大大提高，加入聚丙烯，改善了材料的熔体性能，形成了互穿网络结构的新材料，大大提高了材料在受热状态下的熔体强度，使材料适用于挤出吹塑工艺，同时，选用符合欧盟ROHS标准的环保型阻燃剂，通过合理的配比，阻燃效果可达到UL94V0级。具有生产工艺简单，可重复利用，成形性好，强度高，耐低温性好、耐热温度高，可在120度下长期使用的优点。
