Abstract
The invention discloses a flame-proof flexible photovoltaic decorating wall material for an outer wall. The flame-proof flexible photovoltaic decorating wall material is composed of a flexible substrate and a photovoltaic decorating layer, wherein the flexible substrate is of a layer structure and sequentially comprises an isolating layer, a back glue layer, a lower flame-proof polymer cement mortar layer, a high-toughness glass-fiber reinforced flame-proof non-woven tire base and an upper flame-proof polymer cement mortar layer from bottom to top, and the five layers are fixedly combined into one; the photovoltaic decorating layer sequentially comprises a flexible thin-film battery module, a film layer and a coating layer from bottom to top; and the flexible substrate is mutually stuck with the photovoltaic decorating layer through a flame-proof polymer binder. The flame-proof flexible photovoltaic decorating wall material for the outer wall can replace the traditional photoelectric curtain wall system and does not need to adopt various metal keels, and only the flexible photovoltaic wall material is stuck onto the lighting surface of the outer wall through self-adhesive glue. Thus, the labor and the material are saved, the construction period is greatly shortened, and the building cost is reduced.
Description
Technical field
The present invention relates to the photoelectricity building field, be specifically related to a kind of outer wall flexible photovoltaic decoration wall material and preparation method thereof, described outer wall flexible photovoltaic decoration wall material has photovoltaic generation, fire-proof and water-proof damp proof insulation concurrently, strengthens the multiple use functions such as cracking resistance, architectural decoration, be applied to the photoelectricity building of newly-built and existing building reducing energy consumption, realize building the energy-efficient and required electric power of generating power for their own use.
Background technology
Build a harmonious society, realize that social development has become the fundamental state policy of China's Development of Morden with the harmony between natural environment.Seriously deficient at global resources, the energy, under the severe situation that environment, weather go from bad to worse, China mainly relies on production of energy and the consumption structure of traditional fossil fuel at present, as if the health, coordination and the sustainable development that remain economical, social have been difficult to continue, therefore development is clean, green regenerative energy sources and relevant system integration technology are the task of top priority of energy industry development efficiently, are also the unique selection that solves resource, the energy, natural environment and climate problem.At World Developed Countries such as Europe, the United States, days, the core of energy policy is the green regenerative energy sources that development comprises continuable, the competitive and safety supply of solar energy at present, progressively to reduce the ratio of the fossil fuels such as coal, oil, natural gas, the regenerative resources such as the solar energy of China, resource are very abundant, although through some exploitations, but integral level is still very low, on development speed and level far below most of developed countries.
China is wideling popularize the work of BIPV (Building Integrated PV), but this work also only only limits to the generating of solar energy house top at present, account for the long-pending external wall over half of building surface and but do not obtain effective exploitation, can not meet the scale and benefit of market to the active demand of photovoltaic generation and building photovoltaic generation so far away.The reason that causes the exploitation of external wall photovoltaic generation to lag behind mainly contains the characteristics of China's building and several aspects such as limitation of traditional photoelectricity building.Current China's building town and country present following characteristics: the one, and ratio high-rise, super highrise building obviously increases; The 2nd, adopt in a large number low-intensity, inflammable organic the exterior wall external insulation material; The 3rd, to insulation and waterproof fireproofing, cracking resistance, slip-off preventing and the aging-resistant of ornament materials, require strict all the more; The 4th, the combination of photovoltaic cell component and building exterior wall face also only limits to the demonstration projects such as building glass curtain wall, and its complex structure, involve great expense, and is difficult to large tracts of land and implements.
Part Study person has attempted to develop a kind of photovoltaic generation product of applicable used for building exterior wall, discloses a kind of solar energy power generating exterior wall finish plate and side fascia in the utility model patent manual that China Patent No. is CN201354501Y; A kind of photovoltaic power-generating composite board with external wall or finial function is disclosed in the utility model patent manual that China Patent No. is CN202263950U.In above-mentioned two patents, what in photovoltaic power-generating composite board, as the substrate of photovoltaic cell carriage, all adopt is the hard plate materials such as metal, cement, plastics, modulus of deformation and metope organic insulation material are inconsistent, very easily produce the crack because of heat insulating material and exterior wall photovoltaic panel inhomogeneous deformation generation.
A kind of solar energy ceramic tile is disclosed in the patent of invention manual that China Patent No. is CN200720111588.3.But disclose a kind of power generation solar ceramic tile in the utility model patent manual that China Patent No. is CN201738511U, above two inventions all adopt the form of metal mechanical erection, and complex process is loaded down with trivial details, and need to adopt expensive curtain skeleton.
Exploitation meets the requirement of external thermal insulation system system, but have flexible light weight, fire-proof and water-proof, safe and reliable, strengthen anticracking, photovoltaic generation, architectural decoration several functions, and batch production, standardized production, quality controllable flexible photovoltaic finish material significant.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of outer wall flexible photovoltaic decoration wall material, and it has the multiple use functions such as photovoltaic generation, fire-proof and water-proof, enhancing cracking resistance, architectural decoration concurrently.
A kind of outer wall flexible photovoltaic decoration wall material, by flexible substrate and photovoltaic decorative layer two parts, formed, described flexible substrate is layer structure, comprise successively from the bottom to top: separation layer, gum layer, lower flame-retardant polymer cement sand bed, high-ductility fiberglass reinforced fire retardant nonwoven tire base and upper flame-retardant polymer cement sand bed, five-layer structure is fixed to be integrated.
Described flexible substrate comprises gum layer and separation layer, during construction and installation, only need take the barrier film of flexible photovoltaic decoration wall material bottom off, the wall material directly can be sticked on wall face.
Outer wall flexible photovoltaic decoration wall material of the present invention, wherein said photovoltaic decorative layer comprises flexible thin-film battery assembly, rete and dope layer from the inside to the outside successively.
