The results show that the oxygen index of the thermal insulation board is 35, the board is carbonized at high temperature, does not melt and shrink when meeting fire, and has no drop. The thermal conductivity is as low as 0.025. The thermal insulation effect is outstanding, which can effectively meet the protection of frozen soil layer in tunnel engineering in alpine area.

The surface is compounded with excellent reinforced aluminum foil to reflect the heat source radiation and improve the freeze-thaw protection of frozen soil layer.
