摘　　要：摘要：表征了几种相变石膏板的力学性能和储能性能。结果表明：当十八烷微胶囊含量在0～13．6％时，相变石膏板的力学性能均能符合GB／T9776-2008要求；当十八烷微胶囊含量为13．6％时，相变石膏板的抗折强度为3．3MPa、抗压强度为3．6MPa、熔融温度为26．9℃、熔融焓为10.41J／g、标准温度阻尼率为0．91，并且耐久性能良好。Several properties of the phase change plasterboards were tested in this study. The results show that when the octadecane microcapsule content is 0-13.6%,all the phase change plasterboards can meet the national standard GB/T 9776--2008. When the microcapsules content is 13.6% ,the properties of the plasterboards show the flexural strength with 3.3 MPa,the compressive strength with 3.6 MPa,the melting temperature with 26.9 % ,the melting enthalpy with 10.41 J/g, and the standard temperature damping rate with 0.91. The durability is good.
