Problems solved by technology

[0006] However, the modified polyolefin resin of Patent Document 1 has time-lapse changes after being dissolved in a solvent during long-term storage, and the workability when it is often applied may become unstable. In addition, the adhesion of the formed adhesive layer force may be biased
In addition, there is also a problem that the adhesive force is poor at high temperatures assumed to be used in vehicles, etc.

Embodiment

[0142] Hereinafter, although an Example and a comparative example demonstrate this invention more concretely, this invention is not limited by these Examples at all.

Synthetic example 1

[0144] Into a reaction vessel equipped with a stirrer and a water separator, 220.00 g of "Sovermol908" (manufactured by BASF Corporation) as a hydrogenated dimer glycol, 230.00 g of "EMPOL1008" (manufactured by BASF Corporation) as a hydrogenated dimer acid, and The catalyst was 0.10 g of butyltin dilaurate "KS-1260" (manufactured by Sakai Chemical Industry Co., Ltd.), and at about 240° C., the dehydration esterification reaction was carried out under reduced pressure while flowing out condensation water from normal pressure to obtain poly Ester polyol (hereinafter referred to as polyester polyol (1).).

Synthetic example 2

[0146] Into a reaction container equipped with a stirring device, a thermometer, and a condenser, 108.00 g of "GI-1000" (manufactured by Nippon Soda Co., Ltd., hydrogenated polybutadiene polyol) as the component (a11) and 108.00 g of the component (a2) were charged. 12.00 g of "TCD Alcol DM" (manufactured by Oaksea Co., Ltd., tricyclodecane dimethanol), 0.04 g of hydroquinone monomethyl ether (manufactured by Wako Pure Chemical Industries, Ltd.) as an antioxidant, and "KS- 1260" (manufactured by Sakai Chemical Industry Co., Ltd., dibutyltin dilaurate) 0.03 g, "Desmogel W" (manufactured by Baiel Co., Ltd., methylene bis(4-cyclohexyl isocyanate)) as the component (a3) ​​30.00 g and While stirring 70.00 g of toluene as a solvent (D), the temperature was raised to 85 to 90° C. using an oil bath. Then, the reaction was continued while stirring for 2.5 hours. Then, measure the infrared absorption spectrum, confirm that the absorption of isocyanate group disappears, finish reaction,...

Abstract

This adhesive for laminating a metal foil and a resin film contains a polyol (A), a multimer (B) of a polyisocyanate, and a metal compound (C) which is a compound of at least one metal selected from group 7 and group 12. The multimer (B) of the polyisocyanate contains a multimer (b1) of a saturated aliphatic polyisocyanate and a multimer (b2) of a saturated alicyclic polyisocyanate. The adhesive for laminating a metal foil and a resin film has excellent adhesive strength, and is superior in heat resistance and electrolytic solution resistance.

Description

technical field [0001] The present invention relates to an adhesive for laminating a metal foil and a resin film suitable for an adhesive for packaging materials of a secondary battery such as a lithium ion battery, and an adhesive for laminating a metal foil and a resin film using the same. A laminate manufactured by using an adhesive, a battery exterior packaging material using the laminate, a battery case obtained by molding the battery exterior packaging material, and a method for manufacturing the battery case. Background technique [0002] In recent years, miniaturization, weight reduction, and thinning of electronic devices such as notebook personal computers and mobile phones have progressed. Therefore, high energy density and weight reduction are also required for secondary batteries for electronic equipment, and development of lithium ion batteries having high energy density instead of conventional lead storage batteries and nickel-metal hydride batteries has been ...
