成、汚れ、異物の付看等を避けることが出来なかった。Alkaline batteries such as silver oxide batteries, mercury batteries, and alkaline manganese batteries have recently become smaller and thinner, and are required to have long life and high leakage resistance. For alkaline batteries, insert a separator into the metal cathode container that also serves as the positive terminal (Z negative electrode active), and the metal negative electrode container that also serves as the replacement terminal (after filling with #J quality and alkaline electrolyte). It was fitted with both stirrers via an insulating gasket made of synthetic polymer, and the opening of the positive electrode container was bent inward to seal the magnetism. During use or storage (the decomposition liquid may leak from the periphery of the two negative electrode containers, resulting in damage to the battery used or deterioration of battery performance). Regarding the housing, prevention of alkaline battery leakage (there were many proposals, and the material of the gasket and the type of sealant were being considered). General (

A shape bent at 80° is used. In addition, the cathode tea utensils were made of nickel-plated steel, the gasket was made of nylon, and the cooling agent was made of asphalt. However, with this configuration, it was not possible to prevent liquid leakage during long-term storage under high temperature and high humidity conditions and under normal temperature and normal humidity conditions.

ものである。The object of the present invention is to chemically polish the copper or copper alloy surface of the negative electrode container, and then to remove the epoxy resin from reacting with the epoxy resin between at least this surface and the gasket. A gasket is formed by interposing a resin layer consisting of a mixture of polyoxypropylene amine, of which a portion remains unreacted, and fatty acid polyamide resin in an amount greater than the amount necessary to react with the unreacted epoxy resin. and the negative electrode container] - (Secondly, the above resin layer and negative electrode container are integrated)
Alternatively, the same chemical bonding between copper alloys can be made to improve leakage resistance.

Liquid properties cannot be obtained. The surface of the copper (or copper alloy) is chemically polished to form a strong chemical bond with the active hydrogen of the fatty acid-based polyamide resin (from the second step, it is possible to obtain a battery with the desired leakage resistance). can.

Epoxy resin reacts with epoxy resin and epoxy resin 8
The polyoxypropylene amine, in which some of the fat remains unreacted, reacts with the unreacted epoxy resin.
A resin layer 6 is formed by mixing a necessary amount or more of fatty acid-based polyamide resin. In this resin layer, the 4-boxy equivalent of the epoxy resin is 400 or more, and the active hydrogen equivalent of the polyoxypropylene amine and fatty acid polyamide resin is 600 or less. Furthermore, if the content of the epoxy resin is less than 15% by weight, the adhesion and alkali resistance of the resin layer will decrease.
Since the flexibility and adhesiveness of the resin layer decreases when the number of pages exceeds 0, the amount of epoxy resin is reduced to 15-3% of the total resin amount.
A range of 0% by weight is preferred. The polyoxypropylene amine is required to react with 70% to 9% of the epoxy resin. Furthermore, if the amount of polyamide resin that reacts with the epoxy resin exceeds 50%, the flexibility and adhesiveness of the resin layer will decrease, and the chemical bond with the copper surface will become weaker. 9. Endurance? Since the M fluidity decreases, it is preferable to keep it below 5ON. Here, the polyoxypropylene amine is an aliphatic partial diamine or triamine.

The coexistence resin layer of polyoxypropylene amine, fatty acid-based polyamide resin (epoxy resin cured with 2, and unreacted fatty acid-based polyamide resin) improves the adhesion between the gasket and the negative electrode container and the positive electrode container, and especially In addition, the leakage resistance properties under hot and humid conditions are the same as above.Specially (1) Due to the coexistence of unreacted fatty acid-based polyamide, chemical polishing will make the copper-coated surface of the negative electrode container strong (2). By increasing the flexibility and adhesion of the two-side resin layer, the gap between the gasket and the canal container can be filled with the base material, and the leakage resistance can be greatly improved. By reducing the amount of fatty acid polyamide resin that reacts with the epoxy resin to 501% of the total amount of fatty acid polyamide resin or less, the flexibility of the resin layer can be improved. In addition to being able to maintain the properties and viscosity appropriately, the pot life of the mixed resin liquid can also be managed appropriately.
