摘要 采用熔融共混法制备高密度聚乙烯(HDPE)/膨胀石墨(EG)/石蜡导热定形相变材料(PCM),并对其渗漏率、微观形貌、导热性能和相变潜热进行研究。结果表明:导热定形相变材料中,HDPE,EG和石蜡三种组分具有较好的相容性;PCM中添加EG时渗漏率有所提高,但渗漏率随EG含量的增加而降低;EG含量为15%(质量分数)时,PCM渗漏率低于0.6%;PCM热导率随EG含量的增加而增加,EG含量为15%时,热导率达到1.265W/(m·K);PCM的相变潜热随EG含量的增加变化不大。 The high density polyethylene(HDPE)/expanded graphite(EG)/paraffin thermal conducting shape-stabilized phase change materials(PCM)was prepared by melt blending method.The leakage rate,microstructure,thermal conductivity and latent heat of the composites were studied.The results show that the HDPE,EG and paraffin could be uniformly mixed.The leakage rate of PCM increases when EG is added,but decreases with the increasing of EG content.When the mass fraction of EG is15%,the leakage rate of PCM is less than 0.6%.The thermal conductivity of PCM increases with the increasing of EG content.The value of thermal conductivity is 1.265W/(m·K)when the mass fraction of EG is 15%.The latent heat of PCM is not changed with the increasing of the EG content.
