本発明は、鉛蓄電池に使用される鉛または鉛合
金と合成樹脂を複合した格子体の製造法に関する
ものであり、その目的とするところは耐衝撃性が
あり、耐久性に優れた長寿命で軽量な極板を生産
性よく製造することにある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a lattice made of a composite of lead or lead alloy and synthetic resin used in lead-acid batteries, and its purpose is to have impact resistance and durability. The goal is to manufacture long-life, lightweight electrode plates with good productivity.
通常、鉛蓄電池の格子体は鉛合金を鋳造するこ
とにより製造され、軽量薄形化が図られてきた
が、鋳造およびその後工程での問題から、鋳造格
子の軽量化には一定の限度があつた。 Normally, the grid bodies of lead-acid batteries are manufactured by casting lead alloy to make them lighter and thinner, but due to problems in casting and subsequent processes, there are certain limits to the weight reduction of cast grids. Ta.
そこで、導電性の必要な部分にのみ鉛合金を使
用し、ペースト状作用物質を保持する部分には比
重が鉛合金の1/10以下である合成樹脂を使用し
た、いわゆる鉛合金−合成樹脂の複合格子体が考
えられてきた。 Therefore, lead alloy is used only in the parts that require conductivity, and synthetic resin with specific gravity less than 1/10 of lead alloy is used in the part that holds the paste-like active substance, so-called lead alloy-synthetic resin. Composite lattices have been considered.

成樹脂複合格子体が提案されている。 For example, as seen in Japanese Unexamined Patent Publication No. 0-8037, a lead alloy-synthetic resin composite lattice body is formed by inserting a conductive part cast from a lead alloy into a synthetic resin mold and integrally molding it with the synthetic resin. is proposed. Further, Japanese Utility Model Publication No. 43-3535 proposes a lead alloy-synthetic resin composite lattice body in which a synthetic resin lattice body and a lead alloy perforated plate are laminated and bonded.
しかし、これらはいずれも製造工程が複雑であ
るばかりでなく、導電性を有する鉛合金部分が細
い骨や薄い板であるため、わん曲や変形を起こし
やすく、取扱いも困難である。そのため生産性が
悪く、大量生産には適さない欠点があつた。 However, all of these have complicated manufacturing processes, and because the conductive lead alloy portion is made of thin bones or thin plates, they are easily bent or deformed and are difficult to handle. As a result, productivity was low and it was not suitable for mass production.

である。 The present invention aims to eliminate these drawbacks, and the lattice structure used in lead-acid batteries is made by immersing a lattice structure made of acid-resistant thermoplastic synthetic resin in molten lead or lead alloy, or by immersing a lattice structure made of acid-resistant thermoplastic synthetic resin in molten lead or a lead alloy. A thin film of lead or lead alloy is formed on the surface of the lattice structure by pouring molten lead or lead alloy onto the structure, leaving it in the air for a predetermined period of time, e.g. 1 to 10 seconds, and cooling it. At the same time,
The molten synthetic resin of the lattice structure is made to protrude from a part of the surface of this thin film to form minute protrusions.
以下に本発明の実施例を説明する。 Examples of the present invention will be described below.
第１図に示す従来の鋳造格子体と同様な形にポ
リプロピレンで成型された格子構造体１を335℃
に温度コントロールされた溶融鉛中に0.3秒浸漬
後引き上げて、５秒間放置した後に冷水にて冷却
する。 A lattice structure 1 molded from polypropylene in the same shape as the conventional cast lattice body shown in Fig. 1 was heated at 335°C.
It was immersed in molten lead whose temperature was controlled for 0.3 seconds, then pulled out, left to stand for 5 seconds, and then cooled with cold water.
これにより、ポリプロピレン格子構造体１の全
周囲に約200μの厚さの純鉛薄膜２と、薄膜表面
の複数個所にポリプロピレンの微小突起３を形成
することができた。その詳細を第２図に示す。 As a result, it was possible to form a pure lead thin film 2 with a thickness of approximately 200 μm around the entire circumference of the polypropylene lattice structure 1 and polypropylene microprotrusions 3 at multiple locations on the surface of the thin film. The details are shown in Figure 2.

を形成する。 When a polypropylene lattice structure is immersed in molten lead, the polypropylene on the surface melts, and the surrounding lead tends to solidify due to the heat absorbed by the polypropylene. When it is pulled up and cooled in this state, the surrounding lead solidifies in the form of a thin film, and due to the cohesive pressure, the molten polypropylene on the surface breaks through part of the surrounding thin film and protrudes outside. This protruding polypropylene is cooled and solidified to form microprotrusions 3 as shown in Figure 2B.

らかけても、浸漬と同様な効果が得られた。 Therefore, the synthetic resin used in the present invention is not limited to polypropylene, but may be any thermoplastic resin, such as polyethylene, polyvinyl chloride, etc. In addition to pure lead, molten lead
Also available in lead alloys, at temperatures of 327-350℃
The best condition was to immerse it for 0.1 to 1 second, then pull it out, leave it in the air for a predetermined period of time, for example, 1 to 10 seconds, and then cool it with water. In this case, if the standing time is longer than this, the resin will become soft and the lattice shape will collapse, making it impossible to manufacture. On the other hand, if the exposure time is short,
The necessary protrusion of the synthetic resin to the outside of the thin film 2 could not be obtained. Note that the same effect as immersion was obtained even when the molten lead alloy was applied from above the synthetic resin.
