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