Description

充电桩电缆用无卤低烟阻燃交联聚烯烃护套料制备方法
技术领域
本发明属于高分子材料改性领域,尤其是涉及到一种充电桩电缆用无卤低烟阻燃交联聚烯烃护套料制备方法。
背景技术
随着电动汽车在我国的快速发展,相关配套产业迎来了新的发展机遇。作为电动汽车不可或缺的重要组成部分,电动汽车电缆自然也受到了极高关注。充电桩电缆料主要要考虑以下几个方面:
1、自然环境: 电动汽车充电用电缆因长期暴露在室外,在使用过程中,会遇到各种恶劣的自然环境,包括大昼夜温差变化、日光照射、风化、潮湿、酸雨、冰冻和海水等,这些自然环境会严重影响充电电缆的寿命和使用性能,甚至降低充电电缆的可靠性和安全性,造成财产损失和人身伤害。
2、人为环境: 充电电缆在使用过程中,因使用灵活,难免会存在人为弯曲、扭曲、拖拽甚至拉伸等现象,极易对充电电缆造成机械损伤;同时,充电电缆可能会受到人为造成的酸碱溶液的浸泡,影响电缆材料的性能,对充电电缆造成损伤。 电动汽车充电电缆使用环境相对恶劣,因此,对充电电缆的柔软性、挠曲性、机械性能以及耐蚀性等都有更高的要求。
3、安全要求: 目前,电动汽车的安全性已经成为业界重点关注的内容。电动汽车的充放电过程,因时间较长、电流强度较大,电缆使用频率高,其安全性应受到高度重视。电动汽车充电电缆在保证良好的绝缘性能基础上,应具有较高的耐热性和耐老化性,同时,在燃烧时应具有良好的低烟阻燃特性,以保证将损失和伤害降到最低。对于电缆要求,实际上就是对电缆料的要求,综合上述要求,充电桩电缆料需要同时具有:良好的机械性能好,柔然、阻燃、耐臭氧、耐酸、耐碱、耐油、耐热水、热收缩性能,普通的低烟无卤电缆料只具有较好的机械性能和阻燃性能。
