Embodiment 1

[0022] A method for building energy storage wood using alkylated carbon black as a filler, comprising the following steps:

[0023] (1) Delignified wood: select fast-growing poplar, select mature sapwood above breast height, the specification is 20mm long x 20mm wide x 20mm thick, free from defects such as cracking, decay and discoloration. After weighing, place the wood specimen in deionized water and vacuumize (-0.1MPa, 1h) to discharge the air inside the wood. Pour 500ml deionized water into the beaker, then add 40gNaOH and 63gNa 2 SO 3 , after heating to 95°C, place the wood in the mixture and cook for 24 hours (the mixture is replaced 3-4 times during the process), and ensure that the wood is submerged in the solution during this period. Finally, place the cooked wood in ethanol boiling liquid at 78°C for 1 hour to replace the moisture in the wood. The prepared wood was kept in absolute ethanol.

Abstract

The invention discloses an energy storage wood construction method using alkylated carbon black as filler. The main steps of the method are as follows: (1) delignification treatment is carried out onwood to open cell wall gaps and improve energy storage space; (2) glycidyl methacrylate is selected as the basic material to prepare organic solvent, then organic solvent and polyethylene glycol 800 are blended to prepare phase change energy storage materials, (3) carbon black is dispersed in sulfuric acid solution and heated to prepare hydroxylated carbon black, then hydroxylated carbon black isdispersed in Tris buffer solution, and dopamine is added to adjust the reaction conditions to prepare dopamine modified carbon black. Dopamine modified carbon black is alkylated with octadecyl isocyanate, finally, it is dispersed in the phase change energy storage material; (4) the phase change energy storage material is immersed into the wood by vacuum pressurization full cell method to obtain the phase change energy storage wood.

Description

[0001] (1) Technical field [0002] The invention relates to the technical field of energy storage, in particular to an energy storage wood construction method using alkylated carbon black as a filler. [0003] (2) Background technology [0004] In recent years, the issue of energy conservation and environmental protection has become one of the important factors affecting social and economic development. With the rapid development of industrial society, the demand and dependence of human beings on energy are increasing, and the development of new green energy, the improvement of energy utilization rate, and the research and development of energy-saving technologies and materials are becoming more and more important. In this context, phase change energy storage technology emerged as the times require. Phase change materials can absorb heat energy through phase changes under heating conditions and release heat energy during cooling, and can store and release heat energy according...
