Description
Technical field
The invention belongs to field of material preparation, be specifically related to the preparation method of organism/matter/expandable graphite composite phase change heat-storing building material.
Background technology
Modern architecture generally adopts light material to make building enclosure, but the thermal capacitance of common light material is less, causes fluctuations in indoor temperature bigger, and this not only causes indoor thermal environment uncomfortable, and air conditioner load is increased, and building energy consumption rises.Phase change material (comprising inorganics and organism) is temperature-resistant in fusing or process of setting, and the latent heat that absorbs or discharge is quite big.Phase change material and common material of construction are organically combined, just form a kind of heat-storing building material, this material has the dual-use function of common building material and phase change material concurrently.At present, the latent heat of the phase change material that may adopt reaches about 170J/g, will need 190 times of quality to phase change material and the common building material stores equal heat when 1 ℃ of temperature variation.Therefore, heat-storing building material has the incomparable thermal capacitance of common building material, can improve the thermal inertia of buildings, the indoor temperature change generated in case amplitude is reduced, improve comfort level, and reduce the on-off frequency of heating or conditioning unit, thereby the operational efficiency that improves equipment is also energy-conservation.
Heat-storing building material is except that the requirement that must satisfy heat accumulating itself (as: storage density is big, stable performance, thermal conductivity height, nontoxic, non-corrosiveness, cost are low etc.), also must satisfy the requirement of material of construction in application, mainly be transformation temperature (require about 20 ℃ of human comfort temperature), with the consistency of material of construction and do not increase combustibility.Although the transformation temperature of the inorganic salt hydrate phase change material that has is suitable, latent heat is big and cheap, but because of it had shortcoming that cold-peace is separated and material of construction is had corrodibility and strong moisture absorption, thereby its less being used in the research of heat-storing building material and in using.At present, domestic and international research mainly concentrates on the organism phase change material, has the organism phase change material of using suitable transformation temperature in material of construction and mainly comprises: Octadecane, butyl stearate and some organic acid mixtures etc.
The preparation method of phase change heat-storing building material mainly comprises following three kinds: in the liquid state organics phase change material after 1, adopting " infusion method " directly construction substrate to be immersed in dissolving, the organism phase change material is penetrated in the porous material of construction matrix.This is organism phase change material and the simplest combined process of construction substrate, but the heat-storing building material of this method preparation, the organism phase change material can flow out from the material of construction matrix or ooze out in (putting) hot operational process storing up for a long time, cause building material surface tiny dispersive phase change material (being called " surperficial frosting " phenomenon) can occur, thereby have a strong impact on the performance of heat-storing building material, also increased the combustibility of material of construction simultaneously.2, adopt " melting mixing method " to carry out organism phase change material and some superpolymer crosslinked compound, the organism phase change material is wrapped in the network of superpolymer, prepare the composite phase-change heat-storage material of typing (being that the phase transformation front and back all can be kept solid-state), and then be applied in the material of construction.Though this method can solve the leakage problems that " infusion method " preparation organism phase change heat-storing building material is occurred, also can suppress the combustibility of material of construction to a certain extent.But the shortcoming that the thermal conductivity of macromolecular material own is low has further worsened the heat transfer property of organism phase change material, and this type organic phase change material is incorporated into the mechanical property that also can reduce material of construction behind the material of construction.3, adopt " situ aggregation method " or " interfacial polymerization " preparation phase-change microcapsule, the organism phase change material is wrapped in the microcapsule body that shell is polymerized by macromolecular material, thereby constitute the composite phase-change heat-storage material of typing, and then the microcapsule phase-change heat accumulating mixed with material of construction, prepare heat-storing building material.But there is the contraction of volume in preparation cost height, the long-time solid-liquid phase change process in the microcapsule phase-change heat accumulating and causes the microcapsule shell stress to change and the disruptive problem, and the macromolecular material shell has also reduced the heat transfer property of organism phase change material.
Summary of the invention
Thereby the object of the invention is exactly to exist the organism phase change material can leak out the performance that influence heat-storing building material in actual applications from material of construction and make material of construction exist combustibility or organism phase change material storing up in order to overcome and to solve existing organism phase change heat-storing building material, heat transfer property in the exothermic process is poor, shortcoming and problems such as cost height, a kind of preparation method of organism/matter/expandable graphite composite phase change heat-storing building material is provided, so that the composite phase change heat-storing building material storage density for preparing is big, cost is lower, and organism phase change material and material of construction consistency are good in heat-storing building material, the organism phase change material can not leak out from material of construction when undergoing phase transition, and the organism phase change material is in storage, good heat-transfer in the exothermic process.
Another object of the present invention is to provide the preparation method of above-mentioned composite phase-change heat-storage material.
The present invention realizes that by following technical solution the preparation method of organism/matter/expandable graphite composite phase change heat-storing building material is: (following per-cent all is weight percentage)
The first step: graphite expanded
It is in the microwave oven of 500～2000W expanded 5～15 seconds that acidifying graphite is placed power, prepares to have the expanded graphite that enriches microvoid structure.
Second step: expanded graphite adsorb organic compound phase-change heat-storage material
Expanded graphite and organism phase change material are carried out blend absorption 1～4 hour being higher than under its transformation temperature, after the organism phase change material is adsorbed to the micropore of expanded graphite, through overanxious, dry, prepare organism/expanded graphite composite phase-changing heat storage material, in composite phase-change heat-storage material, the weight percentage of organism phase change material is 40%～90%.
