- the battery sealing material described above is included in the sealing agent system in which rubber and tar pitch agent dissolved in an organic solvent are widely used for primary batteries and secondary batteries.
- the environmental impact of organic solvents is a problem.
- Japanese Patent Publication No. 63-1706 proposes a sealing agent for aqueous systems.
- the film properties (electrolytic solution resistance, etc.) when forming a sealing material layer are We have problems such as badness in comparison.
- a photocurable resin is used as a sealant to solve the solvent problem.
- An object of the present invention is to provide a sealant composition for an aqueous electrolyte battery that satisfies the performance and does not increase the production cost.
- the first invention of the present application is that (A) an aqueous emulsion of an ethylene-vinyl acetate-vinyl versatate copolymer, and (B) A sealing composition for an aqueous electrolyte battery, comprising one or more components selected from mouth-opened latex, chlorosulfonated polyethylene latex, and styrene monomethacrylate.
- the aqueous electrolyte solution in which the blending ratio of the polymer component (solid content) of the component (A) and the component (B) is (A) component: (8) component 10 to 90:90 to 10% by weight
- the battery sealant composition improves the film strength and workability in a well-balanced manner when a sealing material layer for an aqueous electrolyte battery is formed.
- the copolymer of (A) ethylene-butyl acetate-versaic acid vinyl acid used in the sealant composition of the present invention has a copolymer composition ratio (segment unit ratio of each component) of ethylene monoacetic acid.
- Vinyl: It is desirable that vinyl versatate 15-80: 85-20.
- the (A) copolymer of ethylene acetate butyl vinyl vinyl versatate uses an emulsifier such as polyvinyl alcohol as a protective colloid, and a polymerization initiator, monomers of ethylene, vinyl acetate and vinyl versatate in water. It can be obtained by stirring and mixing at the above ratio, followed by milky polymerization. Further, since the solidified product (sealing material) of the sealing agent composition of the present invention has a high possibility of coming into contact with the electrolytic solution, the properties of the sealing material are insoluble in the electrolytic solution and need to be less swelled. .
- Commercially available aqueous emulsions of (A) ethylene-acetic acid bures-versaic acid bur copolymers that can be used in the present invention include:
- component (A): component (B) 91 to: 100: 9 to 0% by weight, the resin strength and the resistance to electrolytic solution of the resin decrease, resulting in increased leakage.

- the sealant composition of the present invention is applied to the surface of a metal container and / or the surface of an insulating gasket by feeding a predetermined amount with a quantitative pump such as an air-driven quantitative dispenser, a roller pump, or a gear pump. After coating, these coatings are naturally dried or dried at low temperature while maintaining the level so that the sealant composition is not displaced, and the aqueous solvent is removed to form a thin resin layer.
- a quantitative pump such as an air-driven quantitative dispenser, a roller pump, or a gear pump.
- these coatings are naturally dried or dried at low temperature while maintaining the level so that the sealant composition is not displaced, and the aqueous solvent is removed to form a thin resin layer.
- the application is not limited to the method using a metering pump, but can be performed manually using a brush if the amount is small. Also, drying can be performed in a short time by using in combination with a blower or the like, and the process can be made more industrially suitable.
- the thickness of the sealing material layer provided by such a method is usually 0.1 ⁇ m to 1000 ⁇ m, as long as it is arbitrarily selected depending on the size of the metal container and the insulating gasket. If the thickness of the layer is insufficient, there may be a problem of electrolyte leakage or intrusion of moisture or the like, or the layer may be cut. On the contrary, if the layer is thick, it may be difficult to form the layer.
- the sealant composition for an aqueous electrolyte battery of the present invention is formed as a sealing material layer so as to be interposed between a gasket of the aqueous electrolyte battery and the battery container, so that a contact portion thereof is formed.
- a sealing material layer so as to be interposed between a gasket of the aqueous electrolyte battery and the battery container, so that a contact portion thereof is formed.
- sealant composition for an aqueous electrolyte battery of the present invention was prepared at the blending ratios shown in Tables:!
- each component used for the Example is as follows.
- CSM450 latex chlorosulfonated polyethylene latex manufactured by Sumitomo Seiki Co., Ltd.
- Electrolyte immersion (weight change rate ()) 2.7 2.9 -5.4 -2.3 -9.4 2.9 3.2 3.6
- the sealant composition for an aqueous electrolyte battery of the present invention can be suitably used for sealing a battery typified by an alkaline electrolyte battery, and has high anti-electrolytic solution properties. It can also be applied to sealing materials such as capacitors and other electronic parts that use aqueous electrolyte.
