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.
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。
