Zusammenfassung:	The invention provides an ultra-light high-temperature-resistant honeycomb core material and a preparation method thereof. The preparation method comprises the steps: core strip glue printing: core strip glue is printed on material blocks, the width between every two adjacent core strip glue is three times the width of the printed core strip glue, the material blocks are laid, the intervals between the core strip glue in every two vertically adjacent layers of material blocks are equal and equal to the width of the core strip glue, and uncured honeycomb laminated blocks are prepared; core strip glue curing; honeycomb stretching: the honeycomb stacked blocks subjected to pressurizing and curing treatment are stretched till honeycomb cells are stretched to be in a regular hexagon state; dipping in a glue solution: dipping the stretched honeycomb blocks in a high-temperature-resistant dipping glue in a dipping tank; and dipping glue curing: curing the high-temperature-resistant impregnating adhesive at a set tem
