Embodiment 1
[0019] This embodiment provides a kind of wood with high thermal conductivity, and its preparation method is specifically as follows:
[0020] Choose the poplar block of 30mm * 100mm * 100mm and dry in the oven of 80 ℃ for 3 hours standby; Take 70 grams of water glass and dissolve in 130 gram of deionized water, be mixed with the water glass aqueous solution that water glass content is 35%; The dried wood block is placed in the 35% water glass solution, and soaked for 14 hours at room temperature and normal pressure; the wood block impregnated with water glass is put into a closed system, and carbon dioxide gas is introduced at room temperature, and kept for 24 hours. hours; then under the protection of nitrogen, dry at 105°C for 2 hours, and the measured thermal conductivity is 0.38Wm -1 K -1 .
Embodiment 2
[0022] This embodiment provides a kind of wood with high thermal conductivity, and its preparation method is specifically as follows:
[0023] Select 30mm × 100mm × 100mm poplar blocks and dry them in an oven at 100°C for 2 hours for later use; weigh 150 grams of water glass and dissolve in 150 grams of deionized water to prepare a water glass aqueous solution with a water glass content of 50%, and heat to 90°C; the dried wood block was placed in the heated 50% water glass solution and immersed for 3 hours under normal pressure; the wood block impregnated with water glass was put into a closed system, and passed through Inject carbon dioxide gas and keep it for 28 hours; then dry it at 105°C for 4 hours under the protection of carbon dioxide gas, and the measured thermal conductivity is 0.42Wm -1 K -1 .
Embodiment 3
[0025] This embodiment provides a kind of wood with high thermal conductivity, and its preparation method is specifically as follows:
[0026] Choose the poplar block of 30mm * 100mm * 100mm and dry in the oven of 105 ℃ for 1 hour for subsequent use; Take by weighing 200 grams of water glass and dissolve it in 300 grams of deionized water to prepare a water glass aqueous solution with a water glass content of 40%; Put the wooden blocks into the impregnation tank after drying as described above, inject 40% water glass solution after vacuuming, then increase the pressure to 2MPa, the temperature is 90°C, and soak for 2 hours; put the wooden blocks impregnated with water glass into In the closed system, carbon dioxide gas was introduced at room temperature and kept for 24 hours; then under the protection of nitrogen, it was dried at 105°C for 1 hour, and the thermal conductivity was measured to be 0.45Wm -1 K -1 .
