産業上の利用分野
本発明は，袋状とした、リプ付の合成樹脂セパレータを

きた。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a lead-acid battery having a bag-shaped synthetic resin separator with lips. As the proportion has increased, the proportion occupied by the bag-shaped separator has also increased.
従来、この種のセパレータは、主材料としてオレフィン

酸素ガスの攻撃を受け、オレ７イン系樹脂の二重結合か
よび分岐部の損傷によシ重合度が低下し、劣化が進み遂
にはクラック等を生じセパレータの機能を失い蓄電池の
寿命も低下する欠点があった。Conventionally, this type of separator has been produced by melt-mixing a mixture of olefin-based synthetic resin and inorganic powder as main materials with a pore opening agent, using an extruder or 1. 2. It is produced by forming it into a sheet using rolls and then extracting the pore-opening agent with a solvent or the like to obtain a microporous sheet. When a separator made in this way is assembled between the electrode plates of a lead-acid battery and used for charging and discharging, the double bond of the ole7-based resin is attacked by the oxygen gas generated from the anode, especially during charging. The degree of polymerization decreases due to damage to the bridges and branches, and deterioration progresses, eventually resulting in cracks and the like, which causes the separator to lose its function and shorten the life of the storage battery.
これらの欠点の改良法として、形状の変更すなわち陽極
に対向する面にリプを設けることによシ、酸素ガスの攻
撃を緩和することが行なわれている。As a method to improve these drawbacks, the attack of oxygen gas has been alleviated by changing the shape, that is, by providing a lip on the surface facing the anode.
発明が解決しようとする課題
しかしながら、リプが在るために、折り曲げて袋状にす
るという作業が，非常に難しいという問題点がでてきた
。Problems to be Solved by the Invention However, a problem has arisen in that the presence of the lip makes it extremely difficult to fold it into a bag shape.
本発明は、上記の問題点を解消し，酸化劣化防止のため
のリプを備えたセパレータを容易に折り曲げて袋状にす
ることを目的とする。The present invention aims to solve the above-mentioned problems and to easily bend a separator provided with a lip for preventing oxidative deterioration into a bag shape.
課題を解決するための手段
本発明は上記の目的を達成するために、折り目となる部
分のリプを、溶融軟化状態にして圧縮変形させることに
よって容易に折り曲げて袋状にするものである。Means for Solving the Problems In order to achieve the above-mentioned object, the present invention is capable of easily bending the lip of the folded portion into a bag-like shape by melting and softening the lip and compressing and deforming it.
作用
本発明の特徴は、リプ部の樹脂を、溶融軟化状態にして
、圧縮変形させることにある。Function The feature of the present invention is that the resin of the lip portion is melted and softened to be compressed and deformed.
軟化させずにリプを押し潰し、折り曲げて袋状にした場
合には、電池の充放電使用によク、６押し潰したリプを
起点にクラノクが発生し易く、その破断面観察結果から
、リプを変形させた際に微小なクラックを生じ、これを
起点に酸化劣化することが判った。If the lip is crushed and folded into a bag shape without softening, cracks are likely to occur starting from the crushed lip due to charging and discharging of the battery. It was found that when the material was deformed, minute cracks were generated, and these were the starting point for oxidative deterioration.
一方、本発明によれば、押圧による微小なクラックの発
生はないため、充放電によるクラック発生起点とはなら
ず，むしろ、圧縮変形した部分は合成樹脂の密度が増加
するため、耐酸化性が向上すると考えられる。On the other hand, according to the present invention, since minute cracks do not occur due to pressure, they do not become starting points for cracks due to charging and discharging.In fact, the density of the synthetic resin increases in the compressed and deformed areas, which improves oxidation resistance. It is thought that this will improve.
実施例 本発明の一実施例を以下に示す。Example An example of the present invention is shown below.
リプ１付の微多孔性を有するポリエチレンセパレータを
用いて、折り目となる部分のリプ１を、厚さＩＭの熱板
に当接することによって、リプでない部分と同程度の厚
さに変形した後、折ジ曲げ２て袋状にした。Using a microporous polyethylene separator with a lip 1 attached, the lip 1 at the crease portion is brought into contact with a hot plate having a thickness of IM to be deformed to the same thickness as the non-lip portion, and then Fold and bend 2 to make a bag shape.
