Description

一种防辐射电缆料
技术领域
本发明涉及一种防辐射电缆料，属于电缆生产技术领域。
背景技术
目前国内所使用的塑料电力电缆十分广泛，常用于城市地下电网、发电站的引出线路、工矿企业的内部供电及过江、过海的水下输电线。随着经济的迅速发展，电缆的需求市场广阔，推动着电缆料生产技术的进步，电缆料不仅用途广泛，而且对其性能指标有特殊的要求，比如在特殊环境下使用时，对电缆防辐射性能有一定要求。
当前国内对于防辐射电缆的研究还处于空白阶段或者实验阶段，没有达到工业应用水平，因此在防辐射电缆领域的研究极具科技与经济发展意义。
发明内容
本发明的目的是提供一种防辐射电缆料，通过钆和钨等功能粒子优势互补，屏蔽性能得到较大提升。
本发明提供的技术方案：一种防辐射电缆料，包括以下质量份数：树脂100份，硬脂酸1~3份，防老剂1~2份，促进剂1~2份，补强剂15~30份，硫磺0.1~1份，填料10~30份。
优选的，所述树脂为PVC树脂或NBR/PVC树脂的一种。
优选的，所述防老剂为防老剂 264或防老剂 4010NA的一种或多种。
优选的，所述补强剂为炭黑或白炭黑的一种或多种。
优选的，所述填料为氧化锌、氧化钨、氧化钆、碳化硼的混合物。
同时本申请公开了一种防辐射电缆料的制备方法，以树脂的质量为 100 g，分别加入硫磺、氧化锌、防老剂、硬脂酸，在双辊开炼机中混合均匀，缓慢加入 1/3~1/2 炭黑与白炭黑补强填充剂，随后加入剩余的补强填充剂，交替割胶翻炼数次，最后加促进剂继续割胶翻炼，待混炼均匀后下料。制备电缆料时，在树脂中不易分散、溶解度较小的粉料（氧化钆、氧化钨等）在混炼时应首先加入。
有益效果：随着功能填料含量的增加，材料的中子与伽马屏蔽性能显著提升，但由于功能填料的存在会在基体材料中形成应力集中，在一定程度上增加了基体材料的缺陷数，材料的拉伸强度与断裂伸长率均随着功能填料含量的增加有一定的减小，但仍然具有一定的强度和延伸率。氧化钆对低能中子的屏蔽性能优于碳化硼，而考虑到碳化硼具有更宽的中子能量吸收范围，可以将氧化钆与碳化硼并用，以期材料在复杂的中子环境中提供更加优异的防护效果。
具体实施例
下面结合具体实施例对本发明作进一步说明：
一种防辐射电缆料，包括以下质量份数：树脂100份，硬脂酸1~3份，防老剂1~2份，促进剂1~2份，补强剂15~30份，硫磺0.1~1份，填料10~30份。其中树脂为PVC树脂或NBR/PVC树脂的一种，防老剂为防老剂 264或防老剂 4010NA的一种或多种，补强剂为炭黑或白炭黑的一种或多种，填料为氧化锌、氧化钨、氧化钆、碳化硼的一种或多种。氧化钆对低能中子的屏蔽性能优于碳化硼，而考虑到碳化硼具有更宽的中子能量吸收范围，可以将氧化钆与碳化硼并用，因此填料比例氧化锌、氧化钨、氧化钆、碳化硼为2:4:4:1。
