超导电缆用聚丙烯复合绝缘薄膜材料、薄膜及其制备方法
摘要：
本发明公开了一种超导电缆用聚丙烯复合绝缘薄膜材料，基于材料的总重量，按重量份计，包括：聚丙烯80～120份；无机填料30～50份；以及成膜助剂2～10份。本发明还公开了一种超导电缆用聚丙烯复合绝缘薄膜的制备方法以及一种超导电缆用聚丙烯复合绝缘薄膜。该超导电缆用聚丙烯复合绝缘薄膜材料绝缘性能更优、且低温下的绝缘性能良好，抗绝缘老化性能良好，适用于冷绝缘超导电缆用。
摘要（英）：

The invention discloses a polypropylene compound insulating film material for a superconductor cable. Based on the total weight of the material, the polypropylene compound insulating film material isprepared from the following components in parts by weight: 80-120 parts of polypropylene, 30-50 parts of inorganic filler and 2-10 parts of a film-forming additive. The invention also discloses a preparation method of a polypropylene compound insulating film for the superconductor cable and the polypropylene compound insulating film for the superconductor cable. The polypropylene compound insulating film material for the superconductor cable is better in insulating performance, good in insulating performance at low temperature and good in insulation ageing resistance performance and is suitable for a cold dielectric superconductor cable to use.
