送速度を遅くする必要があり、生産性が悪かった。Conventionally, as a separator for alkaline batteries, an ion-permeable separator membrane made by graft polymerizing cellophane or polyethylene and irradiated with radiation, and a woven or non-woven fabric of chemical fiber or natural fiber used as an electrolyte absorber to reinforce this membrane←＋04 However, when the separator membrane, which is made by graft polymerizing cellophane or polyethylene and then irradiated with ion-permeable gold, is punched and inserted into the surface of the anode mixture in which electrolyte has been poured, warping occurs, and it is difficult to assemble the battery. , misalignment, bending, and problems such as internal short circuits occurred. As a countermeasure, a film made by graft polymerizing cellophane or polyethylene and making it ion-permeable by irradiation and woven or non-woven fabric of chemical fiber or natural fiber was added to water with methyl cellulose f) 7 carboxymethyl cellulose, etc. Pasted together with glue (Tokuko 1977)
Publication No. 0-33214) has been proposed. However, in the conventional method, since water is used as a solvent, drying takes time, and hot air drying requires a longer drying oven or a slower conveyance speed, resulting in poor productivity.

However, although separate produced by this method can be used for alkaline manganese batteries, in silver oxide batteries and mercury oxide batteries, silver ions may precipitate into the separator and become metallic silver, or metallic mercury may permeate through the separator. This caused an internal short circuit, making it impossible to use.

法の欠点を解消できたものである。The present inventor previously carried out a method in which a synthetic adhesive was added to a volatile organic solvent to form an adhesive, and the adhesive was applied between an ion-permeable separator and an electrolyte holding material, followed by drying. A gap may be formed between the separator and the electrolyte holding material.
This invention has been developed to solve the problems of the conventional inventions, in which there was a problem that the ion-permeable separator and the electrolyte holding material peeled off during use in the assembly process. After the separator and the electrolyte holding material, which absorbs all of the alkaline electrolyte, are bonded with gold plating, an adhesive consisting of a volatile organic solvent and a synthetic glue is applied to the electrolyte holding material side to absorb the electrolyte holding material tube. With this, the drawbacks of the conventional ion-permeable adhesive method can be overcome.
以下、本発明の実施例を図面を参照して説明する。Embodiments of the present invention will be described below with reference to the drawings.

2 is an electrolyte holding material made of rayon non-woven fabric with a thickness of 0.25 mm;
The electrolyte holding material 1 and the ion-permeable separator 2, which are ion-permeable separators made of cellophane membranes with a thickness of 0.07 mm, are passed through a bonding roller 3 and a drying oven 6, and then bonded to a separator 7.
It is designed to be rolled up as At this time, between the electrolyte retaining material and the ion-permeable separator which have passed through the bonding roller 3 and been bonded in advance, the volatile organic material added to the synthetic glue in the adhesive container 4 is applied to the electrolyte retaining material side. An adhesive made of a solvent is applied through a nozzle 5 and absorbed into the electrolyte holding material, and also wets the ion-permeable separator membrane. The adhesive is then passed through a drying oven 6 to dry. The liquid retaining material 1 and the ion-permeable isolation membrane 2 made of the cellophane membrane are manufactured as a barrier 7 by adhesive bonding. In addition, the adhesive used here was a synthetic glue of carboxyvinyl 1.5m.
The temperature inside the drying oven was 80°C.
