摘　　要：利用稻草的天然空心结构,吸附包裹相变石蜡制作成储能单元,然后采用树脂将储能单元粘结成型,得到树脂基稻草吸附石蜡储能单元定形相变材料。显微分析表明,石蜡与稻草空腔结合紧密,材料在储热过程相变石蜡与稻草无界面脱离现象;热失重分析表明,该定形相变材料在多次相变过程中热失重率小于0.3%,具有很好的热稳定性。Utilized the natural hollow structure of the haulm adsorption and package paraffin to prepare the storage unit, then adopted resin to bonding the storage unit to become a board, gained the resin basal body haulm adsorption paraffin power storage unit figuration phase change material （PCM）. micro-analysis denoted, the paraffin and the haulm cavum combine tightness, and the figuration phase change material do not have interface abscission phenomenon during the phase change process; thermal analysis denoted, the figuration phase change material thermogravimetric ratio lesser than 0.3% within number phase change process, those denote that the PCM has a good heat stability.
