Disclosed is a wave-absorbing impregnation glue liquid, comprising: a two-component epoxy resin; a solvent; a polyether-based siloxane; and carbon powder, wherein the ratio by mass of the two-component epoxy resin to the solvent is 1 : 3 to 1 : 5, the ratio by mass of the two-component epoxy resin to the carbon powder is 3 : 1 to 6 : 1, and the fraction by mass of the polyether-based siloxane in the wave-absorbing impregnation glue liquid is 0.05% - 0.2%. Disclosed is a method for preparing the glue liquid, and also disclosed is a wave-absorbing honeycomb and a preparation method therefor. |
