Patent ID: 11949081

Abstract:
A thermally-conductive structural adhesive for new energy power batteries, including: composition A including 3.3-14 wt. % of a block polymerized telechelic carboxyl compound and/or a block polymerized telechelic amino compound; 0.1-1.0 wt. % of a coupling agent and/or a modifier; 0-1.6 wt. % of curing accelerator; 84-92 wt. % of a thermally-conductive powder; and 0.3-3.0 wt. % of a flame retardant agent; and composition B including 3.3-14 wt. % of a block polymerized telechelic isocyanate compound and/or a block polymerized telechelic epoxy compound; 0-1.0 wt. % of a coupling agent and/or a modifier; 0-1.6 wt. % of a curing accelerator; 84-92 wt. % of a thermally-conductive powder; and 0.3-3 wt. % of a flame retardant agent. The composition A and the composition B are mixed evenly in a weight or volume ratio of 1:(0.25-2) and cured to obtain the thermally-conductive structural adhesive. A preparation of the thermally-conductive structural adhesive is also provided.
