あった。Conventional technology Conventionally, an insulating material has been interposed between the positive and negative terminals of a battery that are exposed on the same surface to prevent short circuits due to contact with external metal parts or liquid junctions due to condensation. Efforts were made to prevent this. Especially lithium batteries,
When a high-output battery such as an alkaline battery is short-circuited, a large current flows, causing the battery itself to generate heat, deforming the battery seal, leaking the built-in electrolyte and damaging the equipment used, or allowing moisture to leak out. When something like this occurs between the two electrode terminals and a liquid junction occurs, electrolysis of water occurs in batteries with a potential of 3V, such as lithium batteries, causing problems such as corrosion of the terminal metal. Uta. As insulating members to solve these problems, polymer materials that have excellent adhesion and adhesion to metals have been used. These adhesives are mainly solvent-soluble or two-component adhesive compositions, but they take a long time to harden, and solvent-soluble adhesives require a long time on the production line. This required a process of scattering the solvent in the battery, increasing battery manufacturing costs.
反面紫外線硬化型の接着組成物は主成分として、分子中
に二重結合などの反応基を有した光重合性プレポリマー
、希釈剤としての光重合性モノマーならびに光反応開始
剤からなる無溶剤型接着組成物であり紫外線を照射する
ことにより瞬時に接着硬化するため多用されつつある。On the other hand, UV-curable adhesive compositions are solvent-free and consist of a photopolymerizable prepolymer with a reactive group such as a double bond in the molecule, a photopolymerizable monomer as a diluent, and a photoreaction initiator as the main components. It is an adhesive composition that instantly cures when exposed to ultraviolet light, so it is becoming more and more widely used.
発明が解決しようとする課題
紫外線硬化型樹脂の接着硬化反応は前述したように紫外
線を照射されることによって光重合性プレポリマーと光
重合性モノマーの重合反応が開始され接着硬化される。Problems to be Solved by the Invention In the adhesive curing reaction of an ultraviolet curable resin, as described above, upon irradiation with ultraviolet rays, a polymerization reaction between a photopolymerizable prepolymer and a photopolymerizable monomer is initiated, resulting in adhesive curing.

が照射されない部分Ｃが少なからず存在していた。However, in the terminal part of the battery, as shown in the enlarged cross-sectional view of the terminal part in FIG. In the ultraviolet curable resin filled in, there was quite a portion C that was not irradiated with ultraviolet rays.
この場合、一般的に紫外線硬化型樹脂は硬化前の液性と

端子面に介在した場合、鉄製の端子材料を腐食させ端子
表面にサビを発生したり、時にはガス発生によって硬化
している樹脂部分を押し上げて樹脂に亀裂を発生させる
ことがあった。In this case, UV-curable resin is generally weakly acidic as a liquid before curing, so if uncured resin is present on the battery terminal surface, it will corrode the iron terminal material and cause rust on the terminal surface. In some cases, the hardened resin part was pushed up due to gas generation, causing cracks in the resin.
課題を解決するだめの手段
本発明は前述した問題点を紫外線を照射されることによ

る。By adding a compound that initiates cationic polymerization when irradiated with active ultraviolet rays, unreacted resin that was not irradiated with ultraviolet rays will be cationically polymerized by the cationic polymerization initiator that is subsequently generated, and the unreacted resin will be removed. This prevents the above-mentioned problems from occurring due to the reaction hardening of the resin.

Reference numeral 1 is an insulating member made of ultraviolet curing resin, which is connected to a terminal plate 2 which also serves as a positive electrode terminal, and a power generating element. The recess B formed by the metal container 3, which has a built-in battery and also serves as the negative electrode terminal, and the insulating packing 4, which insulates both terminals inside the battery and prevents the built-in power generation element from leaking outside, is filled and bonded. Hardened. 5 is a lead wire derived from the active material of the positive electrode of the power generation element, and is electrically connected to the inner surface of the positive electrode terminal 2. UV-curable resins include prepolymers such as epoxy acrylate, polyester acrylate, unsaturated acrylate, and polyene-polythiol. Polyvinyl ether resin, monomer: 1. Polyfunctional acrinole resins with cationic polymerizability such as 6-hexanedio-diacrylate, neopentyl glycol diacrylate, and tetraethylene glycol diacrylate, carbonyl compounds such as penzophenone and diethoxyacetophenone as photopolymerization initiators, and cationic polymerization. As the initiator, hydroperoxides such as t-butinorehydroperoxide and diisopropyrhobenzene hydroperoxider are used.

との比較を行なった結果を表１に示す。The blending amounts of these substances are 20 to 40 parts by weight for the prebolimer resin, 60 to 8 parts by weight for the monomer resin,
The photopolymerization initiator is O. The amount of the cationic polymerization initiator is 0.5 to 2.0 parts by weight. If the amount is within this range, workability is good and it can be sufficiently cured under normal ultraviolet curing conditions. Next, Table 1 shows the results of a comparison of the effectiveness of the present invention with that in which no cationic polymerization initiator was added.

である。The ultraviolet rays used in the experiment were cured by irradiating for 30 seconds at a light intensity of 1500 (IJ/d:) using a high-pressure mercury lamp as the light source. The numbers shown in Table 1 are the results for each 200 cracks in the resin when UV-curable resin is applied to the terminals of a cylindrical lithium battery (housing part B) and cured and stored in a high-temperature bath at a temperature of 70°C. These are the results of a survey and comparison of samples. Table 2 shows the rate of rust formation on the battery terminal surface when the batteries were left at room temperature for 6 months.

ものである。(The following is a blank space) In addition to the effects of the invention, as is clear from the experimental results in Table 1, the ultraviolet curable resin to which the cationic polymerization initiator of the present invention has been added is capable of irradiating ultraviolet rays even when there are areas that are not irradiated with ultraviolet rays. If even a part of the irradiated part is exposed, the polymerization reaction of the resin will proceed due to the cationic polymerization initiator generated in that part, and the resin can be completely adhesively cured. This can prevent cracks in the resin due to rust or gas generation due to corrosion.
