Preparation and Characterization of Diatomite Loaded Composite Phase-Change Materials

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 blending.The structure and performance of composite phase material are characterized using SEM, FI-IR and synthesized thermal analyzer DSC.The results show that the phase change temperature of composite phase change material is 30, and phase change enthalpy is 89.54J/g.With every part preserved, phase change particles are distributed in the diatomite/melted paraffin matrix evenly.Stable 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.
