Description
Technical field
The utility model relates to heat preservation construction material, especially a kind of phase transformation composite insulation boards.
Background technology
Because the increase of building energy consumption causes energy consumption too fast, increasing environmental pollution.How keeping under the prerequisite of sustainable development, using lowest energy consumption to reach the dwelling environment degree of comfort maximization has become the focus of studying in the building energy saving field.By the architectural exterior-protecting construction of constructing with the phase-change accumulation energy constructional materials, can reduce fluctuations in indoor temperature, improve comfort level, make building heating or air-conditioning need not or use energy less, improve efficiency of energy utilization, and reduce the operating cost of the energy.Modern architecture develops to high level, and requiring used space enclosing structure is light material.But common light material thermal capacitance is less, causes fluctuations in indoor temperature bigger.This not only causes indoor thermal environment uncomfortable, but also increases air conditioner load, causes building energy consumption to rise.At present, the latent heat of the phase-change material of employing reaches 170J/g even higher, and common building materials store the quality that equal heat will need 190 times of phase-change materials when 1 ℃ of variations in temperature.Therefore, the composite phase-change building materials have the incomparable thermal capacitance of common building materials, and stable and air-conditioning system operating mode steadily is very favorable for the temperature in the room.
Phase-change material is to utilize the heat that absorbs in the phase transition process or discharge to carry out the material of hidden heat energy storage, and heat reservoir can be divided into sensible heat heat accumulation, latent heat heat accumulation and chemical reaction heat storage three classes according to heat accumulation mode difference.Compare with the sensible heat energy storage material, it is big that phase-change material has an energy storage density, advantages such as heat absorption and heat release under efficient height and the approximately constant temperature, thereby can be applied to a lot of fields, though the chemical reaction thermal regenerator has the big characteristics of energy storage density, application technology and technology are too complicated, can only utilize research field to be paid attention at solar energy at present, application from reality is also far, so phase-change material becomes the main application mode of thermal energy storage.
The phase-change accumulation energy constructional materials has both the advantage of common building materials and phase-change material, can absorb and discharge an amount of heat energy; Can use simultaneously with other traditional building materials; Do not need special knowledge and skills to install and use the accumulation of heat constructional materials; The enough standard production equipment production of energy; On economic benefit, has competitiveness.
The combined process of phase-change material and building materials matrix mainly contains following several method at present: (1) is inserted in the constructional materials after phase-change material is sealed.(2) by soaking the building materials matrix (as gypsum wallboard, cement concrete test block etc.) that phase-change material is infiltrated porous.(3) phase-change material is directly mixed with constructional materials.(4) will add in the constructional materials after the organic phase change material emulsification.
Just present, existing technology mainly is that phase-change material is poured among the building carrier matrix, and making it becomes mixture with the original building material, and its problem mainly is: 1, the phase-change material problem of easily leaking from matrix; 2, phase-change material causes problems such as body of wall STRESS VARIATION, structural strength is on the low side to the effect of matrix material; 3, only be applicable to that the new building thing is on-the-spot and build, can't will have the transformation that the old building thing cuts down the consumption of energy, have problems such as heat insulating effect is limited after perhaps transforming.
Summary of the invention
The utility model provides a kind of heat that absorbs or discharge of giving full play in the phase-change material phase transition process to carry out hidden heat energy storage and stable performance, easy construction, prefabricated phase transformation composite insulation boards with low cost, in order to overcome the shortcoming of aforementioned phase-transition heat-preserving material, realize purposes balanced, efficient, energy-saving and environmental protection.
Described composite insulation boards is by the anticracking topping in front, and the insulating of bottom surface and the phase transformation screed that is in the middle of anticracking topping, the insulating are compounded to form the integral type platy structure.
The utility model utilizes phase-change material the temperature of himself almost to remain unchanged before phase transformation is finished in phase transition process, but the sizable characteristics of latent heat that absorb or discharge keep the construction wall temperature constant relatively; Owing to make the phase transformation composite insulation boards, the original building body do not had the influence of chemical property; Simultaneously, the insulating 3 that constitutes by polyphenyl plate can with the performance of phase-change material on the characteristics that cooperatively interact, limited or when night, heat was slowly discharged, insulating 3 played the iris action that the subtend body of wall transmits heat again in the phase-change material heat storage capacity.
The utility model has the advantages that: 1,, can in large-scale standardized production, guarantee properties of product equilibrium, stable owing to make standardization phase transformation composite insulation boards; 2, the original building body there is not the influence of chemical property, can overcome a series of problems that the phase-change material liquid phase flows, volumetric change is brought, there is not worry with protocorm material production STRESS VARIATION and structural strength, also improved with the shortcoming of protocorm material compatibility difference, large-area construction still can keep its performance basically identical at all; 3, simultaneously because the characteristics that cooperatively interact on the performance of polyphenyl plate and phase-change material, limited or when night, heat was slowly discharged in the phase-change material heat storage capacity, the thermal resistance material plays the iris action that the subtend body of wall transmits heat again, the real temperature adjustment general character of organically having utilized two kinds of materials, the while has also overcome the weakness of homogenous material; 4, board dimension is carefully and neatly done, is easy to moulding, is convenient to mechanization production, and on-the-spot installation efficient height has overcome the difficult point of northern China low-temperature construction simultaneously, and construction technology is simple, convenient, especially is fit to the rebuilding construction that existing old building is cut down the consumption of energy; 5, keep constant relatively, ecological friendly, nontoxic, the long service life of construction wall temperature, stable performance in phase transition process, easy operating.
