Description

一种铅酸蓄电池正极板栅用稀土铅合金
技术领域
本发明涉及一种铅酸蓄电池正极板栅用稀土铅合金，具体地说，涉及一种铅酸蓄电池正板栅用铅钙锡铝稀土合金，属于铅酸蓄电池技术领域。
背景技术
蓄电池的核心部件就是极板，而极板的性能好坏直接决定于板栅和铅膏，板栅的质量好坏取决于板栅铅合金的性能。传统的板栅铅合金为铅钙锡铝合金，其中钙含量在0.08-0.18%范围内，钙在该合金中起增加板栅强度的作用，但钙含量过高会使板栅的耐腐蚀性和铅液的流动性受到影响。因此，板栅铅合金的质量，影响到板栅的强度，板栅铅合金中各合金元素的含量对板栅的机械强度、导电性能和耐腐蚀性、析氢析氧电势都有较大的影响。
发明内容
本发明的目的是提供一种铅酸蓄电池正极板栅用稀土铅合金，该合金是在传统的铅钙锡铝合金中加入了镧、钇和铈稀土元素，并降低了钙元素的含量，镧、钇和铈的加入不仅弥补了由于钙元素减少而降低板栅强度的缺陷，而且还改善了由于钙含量过高而降低板栅耐腐蚀性能。
本发明采用的技术方案是：
一种铅酸蓄电池正极板栅用稀土铅合金，其由下列重量百分比组分的材料熔化制得：钙0.01%～0.12%，锡1.2～2.0%，铝0.02%～0.05%，镧0.01% ～ 0.12%，钇0.01%～0.12%，铈0.02% ～ 0.15%，其余为铅。
优选地，一种铅酸蓄电池正极板栅用稀土铅合金，其由下列重量百分比组分的材料熔化制得：钙0.03%，锡1.32%，铝0.035%，镧0.08%，钇0.06%，铈0.08%，其余为铅。
本发明在板栅铅合金中同时加入了镧、钇和铈稀土元素，其可以细化晶粒，降低合金的晶粒间隙，减少板栅筋条的断裂，增加板栅的耐腐蚀性；同时也增加了板栅与活性物质之间的接触面积，降低了板栅与活性物质之间的接触电阻，从而延长电池的循环使用寿命，增强大电流放电性能和充电接受能力。同时，按照本发明配比制作的板栅合金熔点比传统的铅钙锡铝合金低，流动性好，在浇铸时易成型，气孔等缺陷明显减少，提高生产效率。
