Description

一种耐水海底光伏电缆护套材料
技术领域
本发明涉及电缆技术领域，尤其涉及一种耐水海底光伏电缆护套材料。
背景技术
近些年，国内光伏电缆有较快发展，国内许多企业已具备一定的光伏电缆生产技术，适用于普通场所的光伏电缆国内技术已经可以达到要求。但在一些苛刻条件下，尤其是电缆护套长期浸泡在海水中，电缆的外护层易发生渗透甚至开裂，所以无法满足海水浸泡环境的使用。而普通电缆要达到性要求要从电缆结构上进行改进，如增加耐水防护层，此举大大增加电缆的制作成本及使用成本，不适宜推广。
发明内容
基于背景技术存在的技术问题，本发明提出了一种耐水海底光伏电缆护套材料，交联密度高，耐磨和韧性极好，防水效果极好，即使长期浸泡在海水中仍不易开裂，耐老化性能优异。
本发明提出的一种耐水海底光伏电缆护套材料，其料按重量份包括：腈硅橡胶30-40份，氟硅橡胶10-20份，丙烯酸酯橡胶30-60份，交联剂4-6份，聚乙烯醇缩丁醛1-2份，填充剂75-95份，增塑剂2-4份，歧化松香1-2份，防老剂1-2份。
优选地，交联剂按重量份包括：重铬酸钠1.2-2份，N,N-亚硝基双丙烯酰胺2-8份，过氧化二异丙苯0.2-0.8份。
优选地，填充剂按重量份包括：煅烧高岭土20-40份，滑石粉50-80份，丙烯腈基碳纤维3-14份。
优选地，增塑剂按重量份包括：氧化聚乙烯蜡1-2份，端乙烯基硅油1-2份。
优选地，防老剂按重量份包括：抗氧剂AT-215 0.2-1份，紫外光吸收剂UV-5310.2-0.4份，紫外光吸收剂TB75 0.1-0.2份。
本发明采用腈硅橡胶与氟硅橡胶、丙烯酸酯橡胶复配，在端乙烯基硅油的配合下，相互间分散均匀，加工性能好，经过重铬酸钠、N,N-亚硝基双丙烯酰胺、过氧化二异丙苯固化交联后，交联密度高，可在保证硬度的前提下，耐磨和韧性极好，耐盐碱性能好，防水效果极好，即使长期浸泡在海水中仍不易开裂，耐老化性能优异；而煅烧高岭土、滑石粉、丙烯腈基碳纤维复配，内部含有大量片层结构，作为填充增强料，在降低主料添加量，降低成本的基础上，可进一步增强制品防盐水老化能力；聚乙烯醇缩丁醛与歧化松香、氧化聚乙烯蜡、端乙烯基硅油复配，可促使韧性与硬度达到均衡，综合力学性能作用，与抗氧剂AT-215、紫外光吸收剂UV-531、紫外光吸收剂TB75复配，耐老化性能优良。
