Abstract

The invention provides a phase-change heat-storage composite material containing hexadecanol and a preparation method of the material. The phase-change heat-storage composite material has the advantages of being small in hardness, large in available phase-change latent heat, stable in heat-storage capacity and the like, phase-change temperature below 50 DEG C can be provided, and the phase-change heat-storage composite material can be used for hot compress preparations or a hot compress therapy.

Description

technical field [0001] The invention relates to a phase change heat storage composite material, in particular to a phase change heat storage composite material with a phase change temperature between 35°C and 50°C. Background technique [0002] There are usually two ways for materials to store thermal energy: sensible heat and latent heat (ie, phase change heat). Sensible heat storage is carried out by using the specific heat capacity of the material and the temperature change of the material; latent heat storage is carried out by using the energy absorption and release of the substance during the state transition process, and the latent heat storage is usually much higher than the sensible heat storage. Therefore, using the latent heat of materials for energy storage and heat storage has a broader prospect. [0003] As stated in the non-patent literature "Phase Change Materials and Phase Change Energy Storage Technology", phase change energy storage materials have become a...
