Description

一种高耐腐蚀耐候性的电缆护套
技术领域
本发明涉及一种电缆护套,尤其涉及一种双层的高耐腐蚀耐候性的电缆护套。
背景技术
电缆铺设的范围比较广泛,大多数设在环境气候复杂的室外,靠近两级的北部高山地区周边的寒冷地区,气温非常低(特别是冬季),紫外光强烈,一般的工具线和延长线在低温下护套和绝缘会开裂,失去对输电的保护作用而失效。一般的有机高聚物材料经受不住紫外光老化而失效。而靠近赤道的地区温度很高,日照充足,对于橡胶的抗性要求很高。由于工具线会在户外使用,并且需要经常移动,对线缆的柔软性要求高,特别是极端温度下的柔软性要求高,同时要求产品具有很好的耐候性和抗腐蚀性。
发明内容
本发明的目的在于提供一种在极端户外天气下能够保持良好机械性能和良好使用寿命的电缆护套。
为了实现上述目的,本发明提供的技术方案如下:
一种高耐腐蚀耐候性的电缆护套,包括含锌保护层和含氟外层;含氟外层在外部包裹含锌保护层。
所述的含锌保护层由下述重量份的原料组成:环氧树脂75-94份、填料25-40份、酚醛树脂15-30份、脲醛树脂15-30份、氧化聚乙烯蜡8-14份、氧化锌7-13份、流平剂4-9份;所述的含氟外层由下述重量份的原料组成:有机硅树脂60-88份、氟碳表面活性剂13-46份、滑石粉11-23份、偶联剂5-9份、流平剂4-7份、防老剂2-5份、环保稳定剂1-3份。
进一步,所述的含氟外层通过氟碳表面活性剂与其他原料加温后产生化学反应,促进分子铰链,通过冷拼充分搅融,使得含氟外层具有高化学稳定性、具有高耐蚀性,优良的电绝缘性、超高耐候性、抗紫外线辐照、抗湿防水性、低表面能和低摩擦系数、不粘性和抗沾污性。
进一步,填料为玻璃纤维、氧化铝、石英粉、滑石粉、石棉粉、云母粉、石墨粉的一种或几种。
酚醛树脂,又称电木粉。耐弱酸和弱碱,酚醛树脂具有良好的耐酸性能、力学性能、耐热性能,广泛应用于防腐蚀工程、胶粘剂、阻燃材料、砂轮片制造等行业。酚醛树脂最重要的特征就是耐高温性,即使在非常高的温度下,也能保持其结构的整体性和尺寸的稳定性。交联后的酚醛树脂可以抵制任何化学物质的分解,例如汽油,石油,醇,乙二醇,油脂和各种碳氢化合物,抗化学稳定性强。
脲醛树脂,又称脲甲醛树脂。是尿素与甲醛在催化剂(碱性或酸性催化剂)作用下,缩聚成初期脲醛树脂,然后再在固化剂或助剂作用下,形成不溶、不熔的末期热固性树脂。固化后的脲醛树脂颜色耐弱酸、弱碱,绝缘性能好,耐磨性极佳,价格便宜。
氧化聚乙烯蜡,具有粘度低、软化点高、硬度好等特殊性能,无毒性,热稳定性好,高温挥发性低,对填料、颜料的分散性极佳,既有极优的外部润滑性,又有较强的内部润滑作用,还具有偶联作用,可提高塑料加工的生产效率,降低生产成本,在常温下的抗湿性能好,耐化学药品能力强,电性能优良。
有机硅树脂具有独特的结构,兼备了无机材料与有机材料的性能,具有表面张力低、粘温系数小、压缩性高、气体渗透性高等基本性质,并具有耐高低温、电气绝缘、耐氧化稳定性、耐候性、难燃、憎水、耐腐蚀、无毒无味以及生理惰性等优异特性。
氟碳表面活性剂,能以极低的浓度显著地降低溶剂的表面张力。具有热稳定性高,化学稳定性好、相容性好的特点。氟碳表面活性可在强酸、强碱、强氧化介质等特殊应用体系中稳定有效地发挥其表面活性剂作用,不会与体系发生反应或分解。高的化学稳定性就意味着高的化学惰性,氟碳表面活性剂能与其它各类活性剂很好地相容。
本发明的有益效果:
在户外极端天气下也能保持良好的张力、柔软度、机械性能,耐候性能好,双层结构防水性能好,具有高化学稳定性、高热稳定性,具有高耐蚀性、高抗紫外线能力的特点。电缆护套在户外长期使用的环境下,不易老化,抗冲击性能增强,使用寿命增加。
