Abstract
The invention discloses a kind of NEW TYPE OF COMPOSITE Organic substance sizing heat accumulating and preparation method thereof, the heat accumulating is made up of the mixing of paraffin, graphite and copper powder, the mass fraction of wherein paraffin accounts for 80%, the mass fraction of graphite accounts for 12%, the mass fraction of copper powder accounts for 8%, and the paraffin melting point selected in above-mentioned material is between 30 DEG C -60 DEG C.The material has heat absorption exotherm rate faster, the constant advantage of profile after phase transformation.
Description
Technical field
The present invention relates to phase-change heat-storage material field, refers in particular to the heat accumulating of a kind of utilization paraffin, graphite and copper powder compounded preparation.
Background technology
Energy-conservation and the important topic that environmental protection is field of energy utilization, are a kind of new power-saving technologies using the latent heat of phase change storage energy of phase-change heat-storage material.Phase-change material absorbs the heat of surrounding in phase transition process, and when ambient temperature is reduced around, discharges heat to surrounding, so as to reach the purpose of control ambient temperature and energy-conservation.It all has wide practical use in fields such as Solar use, energy recovery, air conditioner refrigerating, building energy conservation, Aero-Space.
Solar energy is had been widely used in the middle of productive life at present as a kind of energy of inexpensive clean, but due to solar energy supply and demand quantitatively with can not match well and coordinate on the time, cause mass energy to waste.As solar energy on daytime is superfluous, cause solar energy to waste, and night and overcast and rainy solar energy are not enough.The shortcoming of current heat accumulating generally existing heat conductivility difference, thus made by phase-change thermal storage part due to poor thermal conductivity, it is impossible to give full play to the heat storage function of heat accumulating.Secondly, when heat accumulating occurs solid-liquid phase change, fluid leakage problems can be caused.
In order to solve the above problems, phase-change heat-storage material strong with certain capacity of heat transmission base material can be combined, and add shaping material, make a kind of new heat accumulating, improve the heat conductivity and sizing characteristics of heat accumulating.
The content of the invention
The heat accumulating it is an object of the invention to provide a kind of NEW TYPE OF COMPOSITE Organic substance is shaped,, in the operating temperature range of solar water heater, latent heat of phase change is higher, and heat conductivility is preferable for the phase-change thermal storage temperature of the heat accumulating, during generation solid-liquid phase change, shape invariance can be kept.
It is a further object of the present invention to provide the preparation method of above-mentioned heat accumulating.
The purpose of the present invention is achieved through the following technical solutions：
A kind of organic heat accumulating of NEW TYPE OF COMPOSITE, it is characterised in that：The heat accumulating is made up of the mixing of paraffin, graphite and copper powder, and the mass fraction of wherein paraffin accounts for 80%, and the mass fraction of graphite accounts for 12%, and the mass fraction of copper powder accounts for 8%, and the paraffin melting point selected in above-mentioned material is between 30 DEG C -60 DEG C.
The preparation method of above-mentioned NEW TYPE OF COMPOSITE Organic substance sizing heat accumulating, using following steps：
（1）Expansible graphite is placed in 60 DEG C of vacuum drying ovens and is dried 10 hours, dried expansible graphite is placed in rustless steel container, be heated to 800 DEG C and expand 60 seconds, obtain expanded graphite；
（2）Copper powder is placed in 60 DEG C of vacuum drying ovens and is dried 1 hour, dried copper powder is mixed with expanded graphite；
（3）Heating paraffin to fusing point is melted, compares paraffin according to quality:Graphite:Copper powder is 20:3:2 add graphite and copper powder, and mixing and absorption 1 hour or so is stirred at 80 DEG C, and cooling is obtained heat accumulating.
The present invention has two advantages：
（1）Heat accumulating heat conductivility prepared by the present invention is higher, and heat absorption exotherm rate is faster；
（2）Heat accumulating prepared by the present invention will not change its profile in phase transformation, effectively can prevent from revealing.
Specific embodiment
Below with example, embodiments of the present invention are described further：
12g expansible graphites are placed in 60 DEG C of vacuum drying ovens and are dried 10 hours, dried expansible graphite is placed in rustless steel container, be heated to 800 DEG C and expand 60 seconds, obtain expanded graphite；8g copper powders are placed in 60 DEG C of vacuum drying ovens and are dried 1 hour, dried copper powder is mixed with expanded graphite；The heating paraffin fusing that 80g fusing points are 60 DEG C is taken, the expanded graphite for processing and copper powder is added, 80 DEG C are heated to, is adsorbed 1 hour or so under agitation, is made heat accumulating.The material phase transformation latent heat is 156kJ/kg.
