发明内容
为填补以上领域需要的空白，本发明专利提供了耐高温500℃导线及其制备方法，导体采用镀镍铜合金绞线，提高了导体的耐温等级，绝缘采用混合型氟材料，满足了其机械性能和耐高温要求，被覆层采用玻璃纤维，增强了导线的耐高温性能。
一种耐高温500℃导线,采用镀镍铜合金线同心绞合作为导体（1），在导体（1）外推挤混合型氟材料绝缘层（2），在绝缘层（2）外编织玻璃纤维被覆层（3）。
进一步，所述的导体采用多股镀镍铜合金线同心同向绞合，并且内外层节距一致。
耐高温500℃导线制备方法，包括如下工艺步骤：
（1）导体采用500型束丝机将多股镀镍铜线绞合在一起，模具采用聚晶模，内外层同左向，节径比控制在10～12倍之间；
（2）导体外推挤混合型氟材料绝缘，混合型氟材料采用F201聚四氟乙烯粉料加入硅系气凝胶混合15min后，放在室温25～30℃环境下存放12小时；推挤时经过速度6～8m/min、温度500℃～520℃高温烧结，使绝缘烧结定型，达到理想的绝缘层。
（3）绝缘外通过16锭编织机编织玻璃纤维被覆层，密度不小于95%。
本发明专利的有益效果体现在：
1、抗腐蚀：绝缘采用混合型氟材料，具有耐化学腐蚀、耐酸碱油及其它溶剂浸蚀等特点。通过温度500℃@4小时试验后，其导线的绝缘电阻值不小于1.5×103MΩ·km，耐压2.5KV@5分钟不击穿。
2、耐高低温：导线长期使用温度在-65～500℃，适用于火炮点火系统和发动机系统极限高温环境下传输电能和信号。
3、机械性能：具有高强度、耐磨损性能，能够很好的满足恶劣环境下的使用。
