关 键 词：Composite Phase Material Diatomite Modification Paraffin 

摘      要：Organic phase change materials like paraffin as phase change material,modified diatomite as carrier,composite phase change material with proper phase change temperature and larger phase change enthalpy is prepared by melt *** structure and performance of composite phase material are characterized using SEM,FI-IR and synthesized thermal analyzer *** results show that the phase change temperature of composite phase change material is 30, and phase change enthalpy is 89.54J/*** every part preserved,phase change particles are distributed in the diatomite/melted paraffin matrix *** composite phase change materials are prepared with diatomite as carrier and paraffin as PCM,which are bonded with Vander Waals forces in the form of physical adsorption.
