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PVC基FSPCM板材的相变温度区间3～18 ℃；当添加MEPCM质量分数为10%时，制备的PVC基FSPCM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。

Abstract:

A novel PVC-based form-stable phase change materials（FSPCM）plates，which comprised of micro-encapsulated PCM（MEPCM）as latent heat storage medium and polyvinyl chloride（PVC）as matrix，was prepared by blending and compression molding. Their microscopic pattern，thermo-physical properties，thermal 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 best，whose blending strength，blending modulus，tensile strength and impact strength were up to 26.7 MPa，3.48 GPa，9.8MPa and 10 kJ/m².
