NOVELTY - Polyurethane foaming glue comprises 50-80 pts. wt. polyol, 20-50 pts. wt. isocyanate, 10-15 pts. wt. cross-linking agent, 0.1-0.3 pts. wt. catalyst, 2-10 pts. wt. elastic regulator, 1-5 pts. wt. accelerator, 2-8 pts. wt. nucleating agent, and 5-15 pts. wt. foaming agent. USE - Used as polyurethane foaming glue. ADVANTAGE - The polyurethane foaming has excellent mechanical property, capable of buffering and anti-seismic action, provides buffer and support for side of naked battery core, reduces aluminum-plastic film deformation, and improves safety of the electric core. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: Preparing the polyurethane foaming glue, comprising (i) heating polyol, isocyanate, crosslinking agent and catalyst, dehydrating, adding dropwise dehydrated isocyanate to the dehydrated polyol, stirring, adding dropwise the dehydrated crosslinking agent and catalyst, stirring, mixing, and heating to form a polyurethane prepolymer to obtain first component, and (ii) mixing elasticity regulator, accelerator, nucleating agent and foaming agent, heating, vacuum dehydrating and cooling to obtain second component; and (iii) mixing and stirring the first component and the second component; use the polyurethane foaming glue, comprising placing naked battery core in a punching hole of the aluminum-plastic film, polyurethane foaming glue prepared by the method is filled to the left and right sides of the naked battery core, filling the polyurethane foaming glue in the gap between the naked battery core and the aluminum-plastic film and curing; and oft pack lithium ion battery. DESCRIPTION OF DRAWING(S) - The drawing shows a polyurethane foaming glue with naked battery core, assembling schematic diagram of the aluminum-plastic film.
