Title:
ALUMINUM-PLASTIC FILM INNER LAYER ADHESIVE FOR LITHIUM BATTERY PACKAGING AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/001711
Kind Code:
A1
Abstract:
The present invention provides an aluminum-plastic film inner layer adhesive for lithium battery packaging and a preparation method therefor. The adhesive comprises a component A and a component B; the component A comprises a low-melting-point polyolefin, an anhydride monomer, an initiator, an auxiliary agent, and a first organic solvent; and the component B comprises a bisphenol A epoxy resin, a modified bisphenol A epoxy resin, and a second organic solvent, wherein the auxiliary agent is a polyfunctional organic small molecule containing a triazine ring. According to the present invention, the low-melting-point polyolefin is used as a matrix resin and is matched with a small number of bisphenol A epoxy resins, and a small number of polyfunctional organic small molecules containing triazine rings are added, so that the bonding strength and electrolyte resistance are remarkably improved; and the components are relatively simple, so that the cost and performance controllability is high, and the economic value is remarkable.
