【発明の詳細な説明】
本発明は鉛蓄電池用基体の製造方法の改良に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a method for manufacturing a base for a lead-acid battery.
従来鉛蓄電池の軽量比を図るため、極板となる基体の軽
量化が進められ、その軽量化のうち、合成樹脂の活物質
保持体と鉛または鉛合金の集電体とからなる軽量化基体
が広く検討されている。In order to reduce the weight ratio of conventional lead-acid batteries, progress has been made to reduce the weight of the substrates that serve as electrode plates. Among these weight reductions, lightweight substrates consisting of a synthetic resin active material holder and a lead or lead alloy current collector have been developed. is being widely considered.
合成樹脂を用いた基体は通常の成形を行なったものでは
表面が滑らかなため、活物質との密着性が悪く、蓄電池
の使用時や組立時に基体から活物質が脱落し易い欠点を
有している。Substrates made of synthetic resin that have been conventionally molded have a smooth surface, which results in poor adhesion to the active material, which has the disadvantage that the active material easily falls off from the substrate when using or assembling the storage battery. There is.
このため基体の一部を構成する活物質保持体の格子形状
を複雑にしたり、表面に細かな傷をつけること等が試み
られたが何れも実用的ではない等の欠点を有していた。For this reason, attempts have been made to complicate the lattice shape of the active material holder that constitutes a part of the substrate, or to make fine scratches on the surface, but these methods have had drawbacks such as being impractical.
本発明は上記の点に鑑み、合成樹脂の格子体と活物質と
の密着性を向上せしめるものである。In view of the above points, the present invention improves the adhesion between a synthetic resin lattice and an active material.
即ち、本発明は合成樹脂の格子体に活物質の原料に用い
る鉛酸化物や鉛の化合物の粉末を保持せしめ、且つ、電
解液が浸透できるよう多孔性を保たせることで、化成後
の極板の活物質と格子体との密着性を向上せしめんとす
るものである。That is, the present invention allows the synthetic resin lattice to hold the powder of lead oxide or lead compound used as the raw material for the active material, and maintains porosity so that the electrolyte can permeate. The purpose is to improve the adhesion between the active material of the plate and the grid.
本発明においては、ポリオレフィン系合成樹脂と鉛化合
物の粉末および可塑剤とからなる原材料を加熱混練した
後射出成形あるいは加圧成形して集電体を一体化する。In the present invention, raw materials consisting of polyolefin synthetic resin, lead compound powder, and plasticizer are heated and kneaded, and then injection molded or pressure molded to integrate the current collector.
然る後可塑剤を溶出または抽出する。The plasticizer is then eluted or extracted.
かくして得られた基体は、内部に均一に鉛酸化物等の鉛
化合物を保持していること、さらにこの化合物の周囲に
は抽出された可塑剤によって形成された微孔を有し、電
解液の浸透が容易である。The substrate obtained in this way uniformly holds lead compounds such as lead oxide inside, and also has micropores formed by the extracted plasticizer around this compound, which prevents the electrolyte from flowing. Easy to penetrate.
該基体にペーストを充填後通常の化成を行なえば基体の
表面に保持された鉛化合物も化成され、活物質層と一体
となり、基体と活物質の密着は犬となる。If the base is filled with paste and then subjected to normal chemical conversion, the lead compound held on the surface of the base will also be converted and become integrated with the active material layer, resulting in tight adhesion between the base and the active material.
またペーストを充填する前に基体を希硫酸中に浸漬して
、基体内部の鉛化合物および充填されるペーストの一部
を硫酸鉛化させること等も密着性の向上に役立つ。Further, it is also useful to improve adhesion by immersing the substrate in dilute sulfuric acid before filling the paste to convert the lead compound inside the substrate and a portion of the paste to be filled into lead sulfate.
本発明に適用できる鉛の化合物は、活物質の原料として
一般に使用されている鉛粉（凡そ６５乃至８０％の酸化
鉛、２０〜３５％の金属鉛からなる）や硫酸鉛、鉛丹、
二酸化鉛等や、それらの混合物があげられる。Lead compounds that can be applied to the present invention include lead powder (consisting of approximately 65 to 80% lead oxide and 20 to 35% metallic lead), lead sulfate, red lead, etc., which are commonly used as raw materials for active materials.
Examples include lead dioxide, etc., and mixtures thereof.
また本発明において形成される格子体の強度や活物質と
の密着性は、合成樹脂や、鉛化合物および可塑剤の配合
比により変化する。Further, the strength of the lattice formed in the present invention and the adhesion to the active material vary depending on the blending ratio of the synthetic resin, lead compound, and plasticizer.
一般に、強度を増そうとして合成樹脂の量を多くすると
密着性が低下し、密着性を向上させようとして鉛化合物
の量を多くすると格子体は胞くなる。Generally, if the amount of synthetic resin is increased to increase the strength, the adhesion will decrease, and if the amount of lead compound is increased to improve the adhesion, the lattice will become porous.
総合的には三成分の配合は合成樹脂／鉛化合物／可塑剤
＝１５〜３０／８〜１７１５８〜７５が最適である。Overall, the optimal combination of the three components is synthetic resin/lead compound/plasticizer=15-30/8-17158-75.
