specific Embodiment approach 1
[0024] Specific Embodiment 1: A method for preparing self-luminous wood that simultaneously stores heat energy and light energy in this embodiment is carried out according to the following steps:
[0025] 1. Immerse the wood in the mixed solution of sodium hydroxide and sodium sulfite, heat it to boiling for 6h-12h, then take it out and wash it with deionized water for 3-5 times to obtain delignified wood;
[0026] The concentration of sodium hydroxide in the mixed solution of sodium hydroxide and sodium sulfite is 2mol / L~5mol / L; the concentration of sodium sulfite in the mixed solution of sodium hydroxide and sodium sulfite is 0.1mol / L~1mol / L ;
[0027] 2. Immerse the delignified wood in a hydrogen peroxide solution with a concentration of 2mol / L to 5mol / L for bleaching, and heat it to boiling for 2h to 4h to obtain bleached wood;
[0028] 3. Mix the rare earth aluminate luminescent material and the melted phase change material at a temperature of 45°C to 70°C to obtain a mi...
specific Embodiment approach 2
[0033] Embodiment 2: This embodiment is different from Embodiment 1 in that the wood described in step 1 is pine, birch, catalpa, red oak, white oak, oak, ash, elm or poplar. Others are the same as in the first embodiment.
specific Embodiment approach 3
[0034] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that the melted phase change material described in step three is melted paraffin, melted polyethylene glycol or melted fatty alcohol. Others are the same as in the first or second embodiment.
