1. A preparation method of a wave-absorbing honeycomb, wherein the preparation method comprises:
dipping a honeycomb into a wave-absorbing impregnation glue liquid, taking out the dipped honeycomb, and then curing them, so as to obtain a wave-absorbing honeycomb; wherein the wave-absorbing impregnation glue liquid comprises:
two-component epoxy resin;
a solvent;
a polyether siloxane; and
a carbon powder;
wherein a mass ratio of the two-component epoxy resin to the solvent is 1:3˜1:5, a mass ratio of the two-component epoxy resin to the carbon powder is 3:1˜6:1, and a mass fraction of the polyether siloxane in the wave-absorbing impregnation glue liquid is 0.05%˜0.2%.
