プ繊維が徐々にほぐれて、極板表面から剥がれる。2. Description of the Related Art An expanded lattice body is more easily deformed than a cast lattice body. Therefore, after filling the lattice body with an active material paste, a protective paper for preventing fall-off of active material is attached so as to fit into the surface of the electrode plate. The protective paper is a paper mainly composed of pulp fibers, and the electrode plate is cut into a predetermined size in a state where the protective paper is stuck, and then assembled into a battery. The protective paper incorporated into the battery while attached to the electrode plate gradually loosens the pulp fibers during charging and discharging of the battery, and peels off from the surface of the electrode plate.
発明が解決しようとする課題 上記のような極板を電解液が非流動化されている密閉
形鉛蓄電池に使用した場合には、次のような問題があ
る。Problems to be Solved by the Invention When the above-mentioned electrode plate is used for a sealed lead-acid battery in which the electrolyte is not fluidized, there are the following problems.
すなわち、ほぐれたパルプ繊維が極板とセパレータの
間に残留し極板間の内部抵抗を増加させるために、密閉
形鉛蓄電池の放電性能を低下させることである。That is, since the loosened pulp fibers remain between the electrode plate and the separator to increase the internal resistance between the electrode plates, the discharge performance of the sealed lead-acid battery is reduced.
活物質ペーストを充填した後極板表面に貼り付けた保
護紙を、電池内まで持ち込まなくても済むようにするこ
とが重要であり、本発明に係る製造法は、このような課
題を解決することである。It is important that the protective paper attached to the electrode plate after filling with the active material paste does not need to be brought into the battery, and the manufacturing method according to the present invention solves such a problem. That is.
課題を解決するための手段 本発明に係る鉛蓄電池極板の製造法は、エキスパンド
格子体に活物質ペーストを充填した後に貼り付ける保護
紙として、耐酸性、撥水性材料からなるものを用いる。
例えば、合成繊維からなる織布、不織布である。Means for Solving the Problems In a method for manufacturing a lead-acid battery electrode plate according to the present invention, as a protective paper to be attached after filling an expanded grid body with an active material paste, a protective paper made of an acid-resistant and water-repellent material is used.
For example, a woven or nonwoven fabric made of synthetic fibers.
そして、保護紙を貼り付けた極板を希硫酸に浸漬し、
極板表面のみを乾燥させた後に、保護紙を剥がして極板
を所定寸法に裁断することを特徴とする。Then, immerse the electrode plate with the protection paper in dilute sulfuric acid,
After drying only the electrode plate surface, the protective paper is peeled off and the electrode plate is cut into a predetermined size.

が起こりにくくなっている。保護紙は、耐酸性の材料か
らなっているため希硫酸に浸漬後も劣化しておらず、
又、撥水性であることから良好に剥がすことができる。Effect In the method according to the present invention, at the stage of peeling the protective paper, the active material is less likely to fall off. That is, in a state where the electrode plate surface is dried by immersion in dilute sulfuric acid, a layer of dry lead sulfate is formed on the electrode plate surface, so that the active material is less likely to fall off. Since the protective paper is made of acid-resistant material, it does not deteriorate even after immersion in dilute sulfuric acid.
Moreover, since it is water repellent, it can be peeled off favorably.

た。The lead sheet 1 is sent to the expanding device 2 and converted into a continuous expanded lattice 3. The expanded lattice 3 is sent to an active material paste filling machine 4 to fill the lattice 3 with the active material paste. At this time, the lower surface of the lattice body 3
It is supported by endless protective paper 5. The upper surface of the grid 3 filled with the active material paste is covered with an endless protective paper 5 '. Protective sheet 5, 5 ', a nonwoven fabric made of polyester fiber, thickness of 0.036 mm, was used having a basis weight of 40 g / m 2.
極板表面を保護紙5,5′で覆った状態で希硫酸浸漬装
置６（希硫酸比重1.05）に送り、次いで乾燥機７で極板
表面を乾燥する（60℃、約１分間）。While the electrode plate surface is covered with protective papers 5,5 ', it is sent to a dilute sulfuric acid immersion device 6 (dilute sulfuric acid specific gravity 1.05), and then the electrode plate surface is dried by a dryer 7 (60C, about 1 minute).

ままの極板と何ら変わるところはなかった。When leaving the dryer 7, the protective papers 5, 5 ′ are peeled off, and the electrode plate 9 having a predetermined size is cut by the cutter 8. The protective papers 5, 5 'could be peeled off favorably because of their water repellency. Further, the situation of the active material falling off from the electrode plate in the cutting step and the subsequent battery assembling step was not different from that of the conventional electrode plate with the protective paper made of pulp fiber attached.

加による放電性能の低下を引き起こすことがなくなる。As described above, in the method according to the present invention, there is no fear that the active material will fall off remarkably even if a protective paper is not adhered to the surface of the electrode plate until the electrode plate is assembled to the battery. As a result, the protective paper is prevented from being brought into the battery, and when this electrode plate is applied to a sealed lead-acid battery, a decrease in discharge performance due to an increase in internal resistance does not occur.
