Provided a wave-absorbing impregnation glue liquid, including: 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%. A wave-absorbing impregnation glue liquid, a wave-absorbing honeycomb and their preparation methods are further provided.

Wave-absorbing impregnation glue liquid, wave-absorbing honeycomb, and preparation methods thereof

The present disclosure provides an epoxy resin wave-absorbing composite material and a preparation method thereof. The method includes: heating an epoxy resin to 50&#xb0; C.&#x2dc;70&#xb0; C., and adding carbon black, to obtain a mixture of the epoxy resin and the carbon black; heating the mixture of the epoxy resin and the carbon black to 100&#xb0; C.&#x2dc;120&#xb0; C., adding a curing agent, and stirring and dissolving them to obtain a mixture of the epoxy resin, the carbon black, and the curing agent; and adding surface-treated hollow glass microbeads into the mixture of the epoxy resin, the carbon black, and the curing agent, and curing them to obtain the epoxy resin wave-absorbing composite material.
