一种用于制造铅酸蓄电池极板的组合物
摘要：
本发明提供用于制造铅酸蓄电池极板的组合物，其特征在于，以重量百分计，包括：铅粉：85％～95％；纤维粉添加剂：5％～15％；所述纤维粉添加剂以重量百分计包括：4％～10％的玻璃纤维粉；80％～90％的蓄电池极板铅膏粉。玻璃纤维中含有SiO2，将该组合物制成极板组装成蓄电池后，SiO2在极板表面形成硅酸凝胶，极板中的微细玻璃纤维和硅酸凝胶提高极板活性物质的结点粘结力，从而提高整个极板的强度，即提高极板的硬挺性。另外，玻璃纤维中的其它元素形成的金属和非金属氧化物在稀硫酸电解液中反应生成盐，增加了PbSO4的溶解度，可以提高蓄电池的充电接受能力，延长了电池的使用寿命。
摘要（英）：

The invention provides a composition for manufacturing a polar plate of a lead acid storage battery. The composition is characterized by comprising the following components in percentage by weight: 85 to 95 percent of lead powder and 5 to 15 percent of fiber powder additive, wherein the fiber powder additive comprises 4 to 10 weight percent of glass fiber powder and 80 to 90 weight percent of storage battery polar plate lead paste powder. The glass fiber contains SiO2; and after the composition is made into the polar plate and then assembled into the storage battery, the SiO2 forms silica gelon the surface of the polar plate, the fine glass fiber and the silica gel in the polar plate improve the adhesiveness of the connection point of the active substance of the polar plate so as to improve the strength of the entire polar plate, namely, improve the stiffness of the polar plate. In addition, the metal and non-metal oxides formed by other elements in the glass fiber react in dilute sulfuric acid to produce salt so as to increase the solubility of PbSO4, improve the charging acceptability of the storage battery and prolong the service life of the battery.
