ト工程。Alkaline IJ batteries such as silver oxide batteries, mercury batteries, alkaline manganese batteries, etc. have recently become smaller and thinner, and are required to have longer lifespan and high leakage resistance. Conventionally, this type of alkaline electrolyte is prepared by filling a positive electrode active material in a metal positive electrode container that also serves as a positive electrode terminal, filling the negative electrode active material and alkaline electrolyte in a metal negative electrode container that also serves as a negative electrode terminal, and then inserting a separator. The inner container was fitted through an insulating gasket made of synthetic polymer, and the opening of the positive electrode container was bent inward to seal the reservoir. However, during use or storage of such alkaline batteries, the solution may leak from the periphery of the negative electrode container, which can corrode the equipment used or reduce battery performance. Became. In addition, there have been many proposals for preventing leakage of alkaline batteries, and various proposals have been made regarding the material of the gasket, the type of sealant, etc. Various improvements have also been made to the structure of the sealing part. In general, conventional negative electrode containers are made of a two-layer clad plate of stainless steel and copper or copper alloy, or a three-layer clad plate of nickel, stainless steel, copper or copper alloy, with copper or copper alloy on the inner surface. A shape that is drawn and bent by 180 degrees around the entire periphery has been used. The positive electrode container was made of nickel-plated steel, the gasket was made of nylon, and the sealant was made of asphalt. However, with such a configuration, it was not possible to prevent liquid leakage during long-term storage at high temperature and high humidity and at room temperature and humidity. Furthermore, the copper of the negative electrode container is formed by drawing a two-layer clad plate of stainless steel and copper or copper alloy, or a three-layer clad plate of nickel, stainless steel, copper or copper alloy, with copper or copper alloy on the inner surface. Or on the copper alloy side, the manufacturing process of clad plate, slitting process.

になった。This invention provides a resin layer between the copper or copper alloy surface of the negative electrode container and the gasket in contact therewith, which is a mixture of an epoxy resin and a fatty acid-based polyamide resin having a larger amount of active hydrogen than the resin that reacts with the resin. If the copper or copper alloy surface is not clean, the chemical bond between the active hydrogen of the fatty acid-based polyamide resin and the copper or copper alloy surface will be weak, making it impossible to obtain sufficient leakage resistance. Or, by cleaning the copper alloy surface by chemical polishing to form a strong chemical bond with the active hydrogen of the fatty acid polyamide resin.
It is now possible to obtain a battery having desired leakage resistance characteristics.
この発明の一実施例を図面に従い説明する。An embodiment of this invention will be described with reference to the drawings.

After processing for about 2 minutes, the copper surface is cleaned by washing with water, neutralizing, washing with water and drying. Next, a resin layer 6 is formed on the surface of the gasket 50 made of nylon 66, which is a mixture of an epoxy resin and a fatty acid-based polyamide resin that has a greater amount of active hydrogen permeable than the amount that reacts with the epoxy resin.

トンの１：Ｌ：１の混合溶剤に溶解した溶液を調製し、
この溶液にガスケットを浸漬して引きあげて乾燥する。The epoxy weight of the epoxy resin should be 400 or more, and the active hydrogen weight of the fatty acid polyamide resin should be 600 or less. If the amount of epoxy resin is less than 15 (by weight), the adhesion and alkali resistance of the resin layer will decrease, and if it exceeds 30 (by weight), the flexibility and adhesiveness of the resin layer will decrease. It is preferable that the amount of epoxy resin be in the range of 15 to 30 (superposition) of the total resin amount.Also, if the amount of fatty acid polyamide that reacts with the epoxy resin exceeds 50, the resin layer and copper surface Not only will the chemical bond with the gasket be weakened, but the flexibility and tackiness of the resin will also decrease, leading to a decrease in leakage resistance.To form a resin layer on the gasket, the resin with the above-mentioned composition must be mixed with a solid content. To make it 10(ffiffi)%,
Prepare a solution dissolved in a 1:L:1 mixed solvent of Improvir alcohol, toluene, and methyl ethyl ketone,
The gasket is immersed in this solution and pulled out to dry.

漏液特性が大巾に向上することがわかる。As is clear from Table 2 below, the negative electrode container was chemically polished under the conditions shown in Table 1 A = F, and a resin layer with the composition shown in A- and FK was interposed between the copper surface of the negative electrode container and the gasket. It can be seen that the leakage resistance of the batteries G to JK, which do not meet these conditions, is significantly improved.

Improves adhesion. Furthermore, alkali resistance and high temperature resistance properties are improved, and since unreacted fatty acid polyamide coexists,
It forms a strong chemical bond with the copper surface of the negative electrode container that has been cleaned by chemical polishing, and increases the flexibility and adhesiveness of the resin layer, completely filling the minute gaps between the gasket and battery container. Therefore, leakage resistance can be greatly improved.

適に管理することができる。The amount of epoxy resin is 15 to 30% (by weight) of the total resin amount, and the amount of fatty acid polyamide resin that reacts with the epoxy resin is 50% (by weight) of the total amount of fatty acid polyamide resin.
By setting the amount to be less than or equal to 1, it is possible not only to appropriately maintain the flexibility and adhesiveness of the resin layer, but also to optimally manage the pot life of the mixed resin liquid.
同、この発明は上記実施例にのみ限定されず、要旨を変
更しない範囲で適宜変形して実施できる。Similarly, the present invention is not limited to the above-mentioned embodiments, but can be implemented with appropriate modifications without changing the gist.
例えば上述の実施例ではガスケット７の全面に樹脂層６

樹脂層６を介在するようにしても上述の効果は充分期待
できる。For example, in the above embodiment, the resin layer 6 is formed on the entire surface of the gasket 7.
However, even if the resin layer 6 is interposed only between the gasket 5 and the negative electrode container 4, the above-mentioned effects can be fully expected.
