Abstract
The invention discloses an inorganic composite phase-change thermal-storage material and a preparation method thereof. The thermal-storage material is prepared by compositing following components, by mass, 82.17% of sodium sulfate decahydrate, 0.83% of high-molecular water-absorption resin (SPA) and 17% of porous foam aluminum, wherein the pore ratio of the porous foam aluminum is higher than 90%. The thermal-storage material is high in speed of heat absorption and releasing, is high in heat storage capacity and is free of deformation after phase change.
Description
One, technical field
The present invention relates to phase-change heat-storage material field, refer in particular to the heat accumulating that one utilizes sal glauberi, hydroscopic high-molecular resin (SPA), fine-crystal spume aluminium alloy compound to prepare.
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 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 inorganic compounding phase-change heat-storage material, 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.
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 inorganic compounding phase-change heat-storage material, it is characterized in that: this heat accumulating is made up of sal glauberi, hydroscopic high-molecular resin (SPA), fine-crystal spume aluminium alloy compound, wherein the massfraction of sal glauberi accounts for 82.17%, hydroscopic high-molecular resin (SPA) massfraction accounts for 0.83%, the massfraction of fine-crystal spume aluminium alloy accounts for 17%, and the fine-crystal spume aluminium alloy voidage selected in above-mentioned materials is more than 90%.
The preparation method of above-mentioned inorganic compounding phase-change heat-storage material, adopts following steps:
(1) fine-crystal spume aluminium alloy is processed into required shape and size;
(2) make mould according to required shape, the fine-crystal spume aluminium alloy processed is placed in mould;
(3) melted by sal glauberi, add hydroscopic high-molecular resin (SPA) according to 1% mass ratio, mixture, after 1 hour, is injected mould by whip attachment, makes mixture liquid just submergence fine-crystal spume aluminium alloy;
(4) by sal glauberi, hydroscopic high-molecular resin (SPA), the cooling of fine-crystal spume aluminium alloy mixture, remove mould, obtain high heat conduction phase-change heat-storage material.
The present invention has three 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 maintains the physics-chem characteristic of each composition of heat accumulating, has stable, that enthalpy of phase change is high feature.
(3) 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:
Fine-crystal spume aluminium alloy is processed into the right cylinder of φ 46*1500.Make mould according to the size of φ 46*1500, and ready-made fine-crystal spume aluminium alloy is inserted in mould.By sal glauberi heat fused, add hydroscopic high-molecular resin (SPA) according to 1% mass ratio, mixture, after 1 hour, is injected mould by whip attachment, makes mixture liquid amount just submergence fine-crystal spume aluminium alloy.Heat accumulating of shaping is obtained after mould is removed in cooling.Fine-crystal spume aluminium alloy selects the material of porosity 90%, and therefore in mixture, fine-crystal spume aluminium alloy massfraction accounts for 17%, and sal glauberi massfraction accounts for 82.17%, and hydroscopic high-molecular resin (SPA) massfraction accounts for 0.83%.This material phase transformation latent heat is 197kJ/kg.
