ガラス織布のバインダーとしては従来のクラツド
式極板用のチユーブの如くフエノール樹脂を用い
る事が通常であつた。 Conventionally, in order to improve the lifespan of the positive electrode plate, an active material is filled in a base that integrates a lead lattice body and a synthetic resin body, and a mat body is brought into contact with the front and back surfaces of the pole plate, and the synthetic resin body and the mat body are bonded together. A method for manufacturing positive electrode plates for lead-acid batteries has been proposed that involves thermal welding. As the synthetic resin body that is part of the base of the electrode plate, any thermoplastic synthetic resin that has acid resistance and oxidation resistance can be used.
(up to 400°C) atmosphere and the presence of dissolved oxygen in the battery.If synthetic resin such as polypropylene is used, which is vulnerable to oxygen atmosphere, the welding strength of the heat welded part will be reduced, which may lead to Peeling is expected, and the effect of improving the life of the positive electrode plate will be reduced. In addition, woven glass cloth is considered to be effective as a material for the mat body in terms of strength, but
As a binder for the glass woven fabric, phenolic resin has usually been used as in tubes for conventional clad type electrode plates.
ガラス織布のマツト体にバインダーとしてフエ

め、合成樹脂体の溶けた一部とマツト体とのから
み状態が悪い。その結果、合成樹脂体とマツト体
との溶着強度が小さくなる欠点を有している。 When a phenolic resin is used as a binder for a mat body made of glass woven fabric, the state of thermal welding between the synthetic resin body, which is a part of the base body, and the mat body is essentially not a heat-welded state, but a synthetic resin body. Some of the melted material is entangled with the pine body. Therefore,
If the phenolic resin is attached to the mat of glass woven cloth, the glass fibers are fixed without coming apart, so that the melted part of the synthetic resin and the mat are not entangled. As a result, the welding strength between the synthetic resin body and the mat body is reduced.
本発明は上記の如き欠点を除去するものにし
て、極板の寿命を大巾に延長せしめるものであ
る。 The present invention eliminates the above-mentioned drawbacks and greatly extends the life of the electrode plate.
本発明の一実施例を説明する。 An embodiment of the present invention will be described.
合成樹脂体１の材質としてポリエチレン樹脂を
使用し、マツト体２の材質は強度の大なるガラス
織布を使用する。 The material of the synthetic resin body 1 is polyethylene resin, and the material of the mat body 2 is a glass woven fabric with high strength.

にはフエノール樹脂が存在しないため、この部分
のマツト体２のガラス繊維は固化していないので
自由度が大きい。そのため熱溶着時合成樹脂体１
の溶けた樹脂がガラス繊維間に容易に流入する。
その結果マツト体２と合成樹脂体１とのからみ状
態が良好となり溶着強度が著しく向上する。 After impregnating the mat body 2 of glass woven cloth with phenolic resin and adhering it by heat treatment, the mat body 2 is heat-treated at a high temperature (450°C to 700°C) at the heat-welded part between the mat body 2 and the synthetic resin body 1, A product with phenolic resin removed was used. By doing this, since no phenol resin is present in the welded portion of the mat body 2 with the synthetic resin body 1, the glass fibers of the mat body 2 in this area are not solidified, so there is a large degree of freedom. Therefore, during heat welding, the synthetic resin body 1
The molten resin easily flows between the glass fibers.
As a result, the mat body 2 and the synthetic resin body 1 are intertwined in a good manner, and the welding strength is significantly improved.

活物質、６は鉛格子体である。 Note that 3 is the phenol resin removal part 4 of the mat body 2.
Reference numeral 5 indicates the phenolic resin adhering portion of the mat body 2, 5 the positive electrode active material, and 6 the lead lattice body.
本発明によつて得られた極板は、フエノール樹
脂含浸ガラス織布の長所である大なる剛性を有

ト体２との溶着強度が著しく増大し寿命が向上し
た。 The electrode plate obtained by the present invention has great rigidity, which is an advantage of the phenolic resin-impregnated glass woven fabric, and furthermore, the welding strength between the synthetic resin body 1 and the matte body 2, which are part of the base body, is extremely high. increased and the lifespan improved.

あつた。 That is, the welding strength of the electrode plate obtained by the present invention is 1.5 times that of the conventional electrode plate using a synthetic resin body made of polypropylene and using a phenolic resin as the binder of the mat body. It was hot.
上述せる如く、本発明は極板の寿命を大巾に延
