Description

铁路机车车辆用电缆
技术领域
本发明涉及机车电缆,具体涉及一种铁路机车车辆用电缆。
背景技术
机车车辆用线缆性能要求较多,特性值高。例如,为了适应轨道交通长期运行条件下的加速、制动、运行震动以及其它环境变化等情况下产生的拉、磨、冷热交替等使用要求,机车车辆用线缆需要满足耐油、耐水、耐候、耐老化、高阻燃、高机械强度、高耐磨、抗疲劳等特性要求;为了确保城轨的安全运行,同时预防城轨电气线路故障发生导致的次生灾害,机车车辆用线缆需要满足低烟、无卤、无毒等特性要求,以便于人员在特殊情况下的逃生和救护;为了适应高寒地带、热带地区、高海拔地区等不同地区的环境要求,特性要求应当满足耐高热、耐高寒、耐紫外线、防白蚁等性能要求。
发明内容
本发明的目的是提供一种铁路机车车辆用电缆,该铁路机车车辆用电缆具有高机械强度、耐磨性优异、耐高温性好、耐油性良好、可以快速挤出。
为达到上述目的,本发明采用的技术方案是:一种铁路机车车辆用电缆,包括位于中心的缆芯、内护套层和低烟无卤外护套,所述缆芯和内护套层之间由内向外依次设置有第一尼龙带层、第一聚乙烯层,所述内护套层和低烟无卤外护套之间由内向外依次设置有第二聚乙烯层、第二尼龙带层、镀锡铜丝疏绕层和无纺布绕包层;
所述缆芯进一步包括位于中心的第一铜导体和外铜导体层,所述外铜导体层由6根绞合于第一铜导体外表面的第二铜导体组成,所述低烟无卤外护套由以下重量份的组分组成:
三元乙丙橡胶 50~70份,
二元乙丙橡胶 15~20份,
高密度聚乙烯 10~20份,
马来酸酐接枝聚乙烯共聚物 3~12份,
煅烧陶土 40~60份,
氢氧化镁 20~30份,
磷氮类阻燃剂 15~30份,
硅烷偶联剂 1.2~2份,
氮化硅纳米粉 2~6份,
硼酸锌 1~3份,
硅酮母粒 2~4份,
硬脂酸锌 0.5~1.2份,
氟加工助剂-PPA 0.5~1.4份,
四[β-(3,5-二叔丁基-4-羟基苯基)丙酸]季戊四醇 0.8~1份,
硫代二丙酸双月桂酯 0.9~1.2份,
2-巯基苯并咪唑锌盐 0.6~1.2份,
三羟甲基丙烷三甲基丙烯酸酯 1.5~3份。
上述技术方案中进一步改进的方案如下:
1. 上述方案中,所述高密度聚乙烯的熔体指数为0.08~2g/10min。
2. 上述方案中,所述马来酸酐接枝聚乙烯共聚物的接枝率为0.6%~1.2%,融熔指数为1~10g/10min。
由于上述技术方案的运用,本发明与现有技术相比具有下列优点:
1、本发明铁路机车车辆用电缆,其采用氮化硅纳米粉作为填料,经特定偶联剂Z-6173处理,解决了纳米材料的难分散问题;同时和硼酸锌的按特定比例复配,机械力的作用下在基材树脂中选择性磨除,氮化硅纳米粉颗粒暴露出来作为球形,起到类似“微轴承”即润滑剂的作用,而硼酸锌也由于带有电荷会向表面移动,沉积于摩擦表面形成非晶态或无定型性膜,二者共同作用,提高了材料的耐磨性,制成电线后可以通过ISO6722标准中的刮磨和拖磨试验要求。
2、本发明铁路机车车辆用电缆,其采用特定参数的三元乙丙橡胶50~70份、二元乙丙橡胶15~20份、高密度聚乙烯10~20份及马来酸酐接枝聚乙烯共聚物作为基体材料,与氮化硅纳米粉、硼酸锌混合,并配有特定的偶联剂和润滑剂,这种配合方式不仅保证了在VA含量较低的情况下,达到相当于高VA含量EVM的耐油性能,还获得了较高的物理机械性能,即制成电线后可以通过ISO6722标准中的耐化学流体(汽油、柴油、机油)试验要求,拉伸强度大于17MPa、断裂伸长率大于600%。
3、本发明铁路机车车辆用电缆,其通过添加氟加工助剂FX-5921,与三元乙丙橡胶50~70份、二元乙丙橡胶15~20份、高密度聚乙烯10~20份、马来酸酐接枝聚乙烯共聚物按照特定比例进行搭配,可减少或消除熔体破裂,降低挤出机扭矩,提高熔流比,通过改善挤出工艺最终使材料表面光滑、可快速挤出,具有良好的加工性能。
4、本发明铁路机车车辆用电缆,其采用的氟加工助剂FX-5921和耐磨填料硼酸锌在本配方体系中还起到防滴落和促进结壳的作用,与煅烧陶土、氢氧化镁及磷氮类阻燃剂复配,具有协同阻燃效果,进一步提高了材料在高温燃烧时的结壳性,即对阻燃性能的提升具有促进作用。
