Abstract
The invention discloses a novel organic typed heat storage material and a preparation method thereof. The heat storage material is prepared through mixing paraffin, activated charcoal and electroplating copper powder, wherein the mass fraction of paraffin is 75%, the mass fraction of a mixture of activated charcoal and electroplating copper powder is 25%, and the melting point of the paraffin selected by the material is 30-60 DEG C. The material has the advantages that the speed of heat absorption and heat release is higher, and the appearance is unchanged after phase change.
Description
one, technical field
The present invention relates to phase-change heat-storage material field, refer in particular to a kind of heat accumulating utilizing the copper powder compounded preparation of paraffin, gac and plating.
two, background technology
Energy-conservation is an important topic of field of energy utilization with environmental protection, utilizes the latent heat of phase change storage power of phase-change heat-storage material to be a kind of novel power-saving technology.Phase change material, in phase transition process, absorbs the heat of surrounding environment, and when envrionment temperature reduces around, Environment release heat towards periphery, thus reach control ambient temperature and energy-conservation object.It all has wide practical use in fields such as Solar use, energy recovery, air conditioner refrigerating, building energy conservation, aerospace.
Sun power, as a kind of energy of inexpensive clean, is widely used in the middle of productive life at present, but quantitatively with on the time can not well mate and coordinate due to the supply and demand of sun power, causes mass energy to waste.As superfluous in sun power on daytime, cause sun power to waste, and night and overcast and rainy sun power not enough.The shortcoming of current heat accumulating ubiquity heat conductivility difference, the phase-change thermal storage parts therefore made, due to poor thermal conductivity, cannot give full play to the heat storage function of heat accumulating.Secondly, during heat accumulating generation solid-liquid phase change, fluid leakage problems can be caused.
In order to solve the problem, by phase-change heat-storage material and the strong base material compound of certain capacity of heat transmission, and shaping material can be added, making a kind of novel organic shaping heat accumulating, improve thermal conductivity and the sizing characteristics of heat accumulating.
three, summary of the invention
The object of this invention is to provide a kind of novel organic shaping heat accumulating, the phase-change thermal storage temperature of this heat accumulating is in the operating temperature range of solar water heater, and latent heat of phase change is higher, and heat conductivility is better, when there is solid-liquid phase change, shape invariance can be kept.
Another object of the present invention is to provide the preparation method of above-mentioned heat accumulating.
The object of the invention is to be achieved through the following technical solutions:
A kind of novel organic shaping heat accumulating, it is characterized in that: this heat accumulating is mixed by paraffin, gac and plating copper powder and forms, wherein the massfraction of paraffin accounts for 75%, the massfraction of gac and electro-coppering powder mixture accounts for 25%, and the paraffin melting point selected in above-mentioned materials is between 30 DEG C-60 DEG C.
The preparation method of above-mentioned novel organic shaping heat accumulating, adopts following steps:
(1) bar shaped activated carbon to be placed in copper electroplating liquid energising plating as negative electrode, after be placed in 60 DEG C of loft drier dry 5 hours;
(2) dried gac pulverizing, grinding are obtained gac-copper powder mixture;
(3) heating paraffin is melted to fusing point, according to quality than paraffin: gac-copper powder mixture is that 3:1 adds gac-copper powder mixture, under agitation mixing and absorption 1 hours, the obtained heat accumulating of cooling.
The present invention has two advantages:
(1) the heat accumulating heat conductivility prepared of the present invention is higher, and exotherm rate is faster in heat absorption;
(2) heat accumulating that prepared by the present invention can not change its profile when phase transformation, can effectively prevent from revealing.
four, embodiment
Below with example, embodiments of the present invention are described further:
Bar shaped activated carbon to be placed in copper electroplating liquid energising plating as negative electrode, after be placed in 60 DEG C of loft drier dry 5 hours; Gac pulverizing, grinding are obtained gac-copper powder mixture; Get the heating paraffin fusing that 75g fusing point is 60 DEG C, take 25g gac-copper powder mixture and add, be heated to 80 DEG C, under agitation adsorb 1 hours, make heat accumulating.This material phase transformation latent heat is 146kJ/kg.
