The invention belongs to the field of preparation of composite boards, and discloses a temperature-adjustable carriage board and a preparation method thereof. The carriage board comprises a first panel layer, a second panel layer and a sandwich layer located between the first panel layer and the second panel layer, the sandwich layer is a foam layer or is formed by stacking two or more foam layers, and each foam layer is formed by splicing a plurality of foam blocks; the first panel layer and the second panel layer are made of fiber reinforced resin matrix composite materials; each foam block is a polyurethane foam block, a PVC foam block or a phenolic foam block; a groove is inwards formed from the middle part of the surface of one side of each foam block, and the groove is filled with a phase-change material. According to the carriage board, the foam blocks and the phase-change materials are combined to serve as the sandwich layer, the foam blocks are of hollow structures and are filled with the phase-change materials, overheat energy can be absorbed by adding the phase-change materials, the temperature can be kept constant, and therefore the whole sandwich layer has the excellent heat preservation performance under the condition that the overall thickness of the board is not affected.

    本发明属于复合板材的制备领域,公开一种温度可调车厢板及其制备方法。包括第一面板层、第二面板层以及位于两者之间的夹芯层,所述夹心层为一层泡沫层或由两层以上泡沫层叠加而成,每层泡沫层由若干个泡沫块相互拼接而成;所述第一面板层、第二面板层为纤维增强树脂基复合材料;所述泡沫块为聚氨酯泡沫块、PVC泡沫块或酚醛泡沫块;所述泡沫块自其一侧表面中间部位向内开设有凹槽,凹槽内部填充有相变材料。本发明车厢板将泡沫块与相变材料组合作为夹心层,泡沫块采用中空结构,其内部填充相变材料,相变材料的加入可以吸收过热能量,维持温度恒定,从而在不影响板材整体厚度的情况下,使夹心层整体具备优良的保温性能。
