The invention provides an adhesive for lithium battery packaging. The lithium battery packaging adhesive includes: polyacrylate polyol, polyisocyanate and trimerization cross-linking accelerator; wherein, the mass average molecular weight of the polyacrylate polyol is 30000-70000, and the hydroxyl value is 10mgKOH/g ~15 mgKOH/g. Therefore, the adhesive can complete the curing reaction in a relatively short time, and the outer heat-resistant layer of the aluminum-plastic film and the middle aluminum foil are bonded by the adhesive, and the obtained aluminum-plastic film has good molding properties. stability and stability. |
