Impregnation formula for punched Nomex paper honeycomb and use method thereof

The application belongs to the field of materials and particularly relates to an impregnation formula for punched Nomex paper honeycomb and a use method thereof. A defoamer or a surface additive is added to impregnation glue liquid to reduce surface tension of the glue liquid, so that when a honeycomb core plate is moved out from a glue trough, the holes on walls of the honeycomb lattices are unobstructed. The impregnation formula not only improves impregnation quality of punched honeycomb but also increases efficiency of impregnation of the punched honeycomb.
