[0069] According to the present invention, there is also provided a preparation method of the above-mentioned phase change heat storage composite material and a phase change heat storage composite material prepared by the method, the preparation method comprising the following steps:

[0070] 1. Weigh cetyl alcohol, surfactant and water, preferably at 50-60°C, weigh according to the above weight ratio,

[0071] 2. The surfactant is placed in the container, and then an inorganic solvent, preferably water, is added thereto,

[0072] 3. Add cetyl alcohol, preferably under stirring conditions, more preferably batchwise or dropwise, and the stirring speed is 300-1000rpm,

[0073] 4. Mix the above components, preferably by continuous stirring or ultrasonic oscillation to uniformly mix the components, more preferably the ultrasonic oscillation frequency is 100-800W, to prepare a microemulsion phase change heat storage composite material.

[0074] According to the present invention, ...

Embodiment 1

[0104] At 50-60°C, weigh 6.00g cetyl alcohol, 1.00g Tween-80, and 1.5g water,

[0105] Place the weighed Tween-80 in a beaker, add weighed water to it,

[0106] Add the weighed cetyl alcohol dropwise under the condition of stirring, add the weighed cetyl alcohol in 6 times under the condition of stirring, add 1g each time, stir at intervals of 30s,

[0107] The above-mentioned components are fully mixed evenly to prepare a microemulsion phase change heat storage composite material.

[0108] (1) Perform DSC analysis on the prepared phase change heat storage composite material, the procedure is:

[0109] 1) Constant temperature at 80°C; 2) Decrease to 0°C at 10°C / min, the result is as follows figure 2 shown. Depend on figure 2 It can be clearly seen that the enthalpy value is 177.4J / g, and the freezing point is: 44.92°C, 39.15°C.

[0110] (2) Structural characterization of the prepared phase change heat storage composite material by infrared spectroscopy, the results are ...

Embodiment 2

[0112] At 50-60°C, weigh 6.00g cetyl alcohol, 1.00g Tween-80, and 2.5g glycerin,

[0113] Place the weighed Tween-80 in the beaker, add the weighed glycerin at one time,

[0114] After fully stirring to fully dissolve Tween-80, add the weighed cetyl alcohol in 6 times under the condition of stirring, add 1g each time, stir at intervals of 30s,

[0115] Stirring is continued to fully mix the above components evenly, and a microemulsion phase change heat storage composite material is prepared.

[0116] (1) Perform DSC analysis on the prepared phase change heat storage composite material, the procedure is:

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...
