Preparation method of gypsum-based thermal insulation wallboard containing lignocellulose skeleton packaged phase change energy storage material
The invention discloses a preparation method of a gypsum-based thermal insulation wallboard containing a lignocellulose skeleton packaged phase change energy storage material. The preparation method comprises the following steps: heating broadleaf wood chips in a mixed solution of potassium hydroxide, sodium silicate, magnesium sulfate, diethylene triamine pentaacetic acid and hydrogen peroxide, taking out, washing the solid, performing freeze drying to obtain a lignocellulose skeleton material; adding the lignocellulose framework material into a mixture of hexadecanol and coconut oil, carrying out vacuum impregnation treatment, and then carrying out freeze drying to prepare a phase change energy storage material layer; stirring and mixing washed and dried ardealite powder, cement, carbon fibers, bentonite, a dispersing agent, a water reducing agent and water, placing the mixture in a mold for compression molding, demolding, and performing steam curing to obtain a matrix layer; and sequentially stacking the matrix layer, the phase change energy storage material layer and the matrix layer, and performing pressurization treatment to obtain the thermal insulation wallboard. The thermal insulation wallboard prepared by the method not only has good mechanical properties, but also has excellent thermal insulation performance.
本发明公开了一种含有木质纤维素骨架封装的相变储能材料的石膏基保温墙板的制备方法，包括以下步骤：将阔叶木木片在氢氧化钾、硅酸钠、硫酸镁、二亚乙基三胺五乙酸、双氧水的混合溶液中加热处理，取出，对固体进行洗涤后，进行冷冻干燥，制得木质纤维素骨架材料；将木质纤维素骨架材料加入到十六醇、椰子油的混合物中真空浸渍处理，之后进行冷冻干燥，制得相变储能材料层；将水洗干燥后的磷石膏粉、水泥、碳纤维、膨润土、分散剂、减水剂、水搅拌混合后置于模具内压制成型，脱模后蒸汽养护，制得基体层；将基体层、相变储能材料层、基体层依次层叠，进行加压处理，制得保温墙板。该方法制得的保温墙板不仅具有良好的力学性能，且保温性能优异。
