Description
Technical field
The present invention relates to a kind of polyhydric aliphatic acid cut shape phase change material and preparation method thereof, belong to building energy conservation and heat accumulating field.
Background technology
Along with increasingly sharpening of world energy sources crisis, people more and more pay close attention to effective utilization of the energy.Phase change material is a kind of material that can change its physical condition and absorption or discharge large energy in certain temperature range.Solid-liquid phase change material for example, when envrionment temperature is higher than its transformation temperature, it will be liquid from solid state transformation, absorb simultaneously and store a large amount of latent heat; And when envrionment temperature reduced again, phase change material carried out again from liquid state to solid-state reverse transformation, and the heat that stores is discharged in the environment again went.When the physical condition variation occured so repeatedly, the phase change material self-characteristic was almost constant, but envrionment temperature can be maintained in certain scope, reduced calorific loss, the utilization ratio of the Effective Raise energy.
Lipid acid is as non-paraffin class organic phase change material, because it has the advantages such as high melting enthalpy, nonflammable, thermostability that the phase transition process cubical expansivity is little and good and chemical stability, is being used widely aspect building energy conservation and the daily life.But the fusing point of most of lipid acid is higher than the temperature requirement scope of applied environment, therefore usually needs to replace single lipid acid to satisfy the applied environment requirement with binary or Diversity lipid acid.Schroeder's formula is the effective ways commonly used of determining the minimum eutectic proportioning of binary compound fat acid, but the above compound fat acid of ternary and ternary proportioning really rule needs a large amount of experiments, filters out suitable polyhydric aliphatic acid phase change material by the character of measuring product under the different proportionings.
Shaping phase-change material is normally combined by phase change material and various porous material, utilize the fine porosity of porous medium inside that phase change material is dispersed into small-particle to store, improve the stability that phase change material stores by capillary effect in porous medium, and then can keep certain shape when phase change material is undergone phase transition, leakage phenomenon can not appear.Utilize simultaneously the high characteristics of Heat Conduction in Porous Media rate can also improve the heat exchange efficiency of phase change material.Compare with common phase change material, shaping phase-change material has the advantages such as packaging cost is low, and heat transfer resistance is little, is difficult for leaking, and use is safe.
Chinese patent file CN101838521A (application number 201010169075.4) discloses a kind of take bentonite as matrix, take the preparation method of binary of fatty acids as the composite phase-change energy storage material of phase-change accumulation energy main body, the method is at first carried out modification to bentonite, then prepare the binary of fatty acids eutectic mixture with myristic acid and palmitinic acid or with lauric acid and myristic acid, at last modified montmorillonite, binary of fatty acids and dehydrated alcohol are mixed, heat, stir, are dried to constant weight, namely get binary of fatty acids/bentonite composite phase-change material.The transformation temperature of this composite phase-change material is higher, when especially preparing the binary of fatty acids eutectic system with lauric acid and myristic acid, the transformation temperature of final gained composite phase-change material is restricted the application of binary of fatty acids/bentonite composite phase-change material up to 36 ℃.
