Description
技术领域
本发明涉及用于制备减摩带的由聚苯砜(PPSU)和聚四氟乙烯(PTFE)形成的混合物，所述减摩带用作柔性流体管线例如输油管线的减摩中间层(抗磨带)。
背景技术
GB 2 441 066(Technip France)描述了用于输送烃的多层构造的柔性管。在所述至少部分地可彼此相对移动的金属带之间设置减摩塑料带，所述塑料带由具有175℃-255℃的玻璃化转变温度的无定形聚合物组成。所述带由聚苯砜(PPSU)和全氟化聚合物和聚醚醚酮(PEEK)组成。在该发明的一个特定的实施方案中，将由85％聚苯砜(PPSU)与15％聚四氟乙烯(PTFE)形成的混合物混合并挤出而获得厚度1.5mm且宽度大约1m的带材。没有提及所使用的塑料的分子量。

目的的达到
根据本发明的目的通过提供使用由聚苯砜(PPSU)和聚四氟乙烯(PTFE)形成的均匀混合物成功达到，所述聚四氟乙烯具有特别高的分子量和小的粒子尺寸或粒子尺寸分布。所使用的PTFE具有特别高的分子量。然而，它尤其适合于引入工程塑料中，该工程塑料在非常高的熔体温度下加工。
根据本发明的解决方案的整个开发中决定性的是，只有PTFE在整个横截面上在PPSU基体内非常均匀且细分的分布才确保在整个使用期间所希望的效果，其中带的厚度减小，并且确保不但沿挤出方向而且垂直于挤出方向上尤其平衡的机械性能。
聚苯砜(PPSU)

在50Hz下的介电常数根据IEC 60250测得是3.4，在1MHz下的介电常数根据IEC 60250测得是3.5，在50Hz下的介电损耗因子根据IEC 60250测得是6 1e-4。在1MHz下的介电损耗因子根据IEC60250测得是76 1e-4，击穿强度根据IEC 60243-1，根据ASTM测得是15kV/mm。对于所述击穿强度的厚度是3.2mm，根据IEC 60093的比体积电阻是9e15欧姆米。
沿着流动方向/垂直于流动方向的纵向膨胀根据ISO 11359测得是55 10-6/K，根据ISO 11357测得的熔融温度或玻璃化转变温度是215℃，耐热变形性A根据ISO 75 HDT/A(1.8MPa)测得是207℃，耐热变形性B根据ISO 75 HDT/A(0.45MPa)测得是214℃，最高温度(短期)是180℃，最高温度(长期)是160℃(根据UL 746(RTI)MechanicalW/O Imp.，40 000h的热老化)。最小应用温度是负100℃。
聚四氟乙烯(PTFE)
所使用的高分子量聚四氟乙烯(PTFE)是Zonyl
MP 1300型的非常细粒的聚四氟乙烯。这种PTFE特别适合作为基于HT热塑性塑料的聚合物混合物中的添加剂。
具体实施方式
