Abstract:

A novel PVC-based form-stable phase change materialsFSPCMplateswhich comprised of micro-encapsulated PCMMEPCMas latent heat storage medium and polyvinyl chloridePVCas matrixwas prepared by blending and compression molding. Their microscopic patternthermo-physical propertiesthermal stability and mechanical properties were characterized. The results showed that the phase change temperature was between 3 and 18 . When the content of MEPCM was 10%the prepared PVC-based FSPCM plates were the bestwhose blending strengthblending modulustensile strength and impact strength were up to 26.7 MPa3.48 GPa9.8MPa and 10 kJ/m2.

摘要:

采用模压法,将微胶囊包覆相变材料(MEPCM)及必要的助剂添加到PVC基体中,制备出新型PVC基定形相变材料(FSPCM)板材,并对它的微观形状、相变特性、升降温性能及力学性能进行了研究。结果表明:所制备的新型PVCFSPCM板材的相变温度区间318 ;当添加MEPCM质量分数为10%时,制备的PVCFSPCM板材综合性能为最优,其弯曲强度为26.7 MPa,弯曲模量为3.48 GPa,拉伸强度为9.4 MPa,冲击强度为9.39 kJ/m2
