Embodiment 1

[0023] An energy storage wood and semi-interweepating network regulation method based on boron nitride as a filler, including the following steps:

[0024] (1) Decoche wood: Pick fast-growing poplar, select the mature sideworthy of the chest higher, with a specific standard for 20mm × width 20mm × thick 20mm, no cracking, decaying and discoloration. After weighing, the wood test piece is placed in deionized water (-0.1MPa, 1h), and the internal air is discharged.

[0025] (2) Organic solvent: 1 Pharained glycerol ester by the oxidal acrylate is passed to the cylinder, and the methacrylate of methacrylate 2 is mixed with 40 ml of methacrylate and 20 ml of polyethylene glycol 400 to obtain a mixture. , Then 30 ml of toluene and 1 g of triethylamine, mix well, poured into three bottles with stirring devices and reflow devices; 3 will be placed in an oil bath with stirring devices and reflow devices in 80 to 90 ° C In the middle, nitrogen gas is simultaneously introduced, stirred back...

Embodiment 2

[0030] An energy storage wood and semi-interweepating network regulation method based on boron nitride as a filler, including the following steps:

[0031] (1) Decocin wood: Picking the fir, select the mature sideworthy of the chest higher, with a length of 40 mm × width 40mm × thick 20mm, no cracking, decaying and discoloration. After weighing, the wood test piece is placed in deionized water (-0.1MPa, 1h), and the internal air is discharged.

Abstract

The invention discloses an energy storage wood with boron nitride as a filler and a control method for a semi-interpenetrating network. The main steps of the method are: (1) performing delignification treatment on wood to open cell wall gaps and increase energy storage space. (2) Glycidyl methacrylate and polyethylene glycol 400 are copolymerized, and then blended with glycidyl methacrylate to prepare an organic solvent. (3) Boron nitride is dispersed in a buffer solvent, and dopamine hydrochloride is added to react at room temperature for a period of time, so that boron nitride is grafted with dopamine. (4) Melt blending dopamine-modified boron nitride, an organic solvent and polyethylene glycol 800, and adjusting the material ratio and reaction conditions among the three to prepare a phase-change energy storage material. (5) The phase-change energy storage material is immersed in the wood by the vacuum pressurized full-cell method to obtain the phase-change energy storage wood.

Description

[0001] (1) Technical field [0002] The present invention relates to the field of energy storage technology, in particular, an energy storage wood and semi-interpenetrating network regulation method based on boron nitride as a filler. [0003] (2) Background [0004] In recent years, energy-saving and environmental issues have become one of the important factors affecting social and economic development. With the rapid development of industrial society, human beings' demand and dependence on energy are increasing, and the development of new green energy, enhance energy utilization, research and energy saving technology and materials are increasingly valued. In this context, phase change energy storage technology is born, and the phase change material can absorb thermal energy through the object phase change under heating conditions, and release thermal energy during the cooling process, which can achieve thermal energy storage and release depending on the ambient temperature. , Effe...
