Description
Technical field
The present invention relates to a kind of solar panels composite decking, the solar panels composite decking of the particularly coated improvement of a kind of tool.
Background technology
The basic element of character of solar water heater comprises several parts such as absorber plate, transparent cover plate, thermal insulation layer and shell.The Main Function of transparent cover plate be ensure solar radiation effectively through prerequisite under protect absorber plate, corrode absorber plate with dust protection, sleet etc. and cause it to damage.The material that can be used for manufacturing transparent cover plate mainly contains two large classes, i.e. safety glass and glass epoxy.The former is inorganic material, has good weatherability, light transmission, is at home and abroad widely used.Glass epoxy basic structure is glass fiber reinforcement transparent resin plate, main advantage comprise solar transmission than high, thermal conductivity factor is little (good heat insulating), shock-resistant etc.Particularly glass epoxy quality opposing glass steel plate greatly alleviates, and is extremely conducive to the lighting of solar thermal collector and the installation and transportation of solar water heater.Meanwhile, glass epoxy has good formability, can be processed into various shape according to actual needs.And portability and formability exactly safety glass institute unapproachable.
But the major defect of glass epoxy is that its weatherability is poor.On the one hand, ultraviolet light causes the degraded of resin material, not only affects its mechanical property, also causes glass epoxy flavescence, light transmission efficiency reduction; On the other hand, the wearing and tearing such as the sand and dust in air, the acid-base material in rainwater and erosion, cause its surface to scratch, also can reduce light transmission efficiency.
To this, in prior art prepare take glass epoxy as the transparent cover plate of constituent material time, the resin base material of special substance can be adopted, to reduce the xanthochromia degree under its ultraviolet irradiation, such as use alicyclic polyamide class material, but glass epoxy prepared by special material often causes product cost significantly to promote; Or superimposed, each layer of Multilayer ultrathin glass epoxy uses different materials, and to having complementary advantages between different layers, but loaded down with trivial details preparation technology result in the lifting of transparent cover plate cost equally.
Summary of the invention
For many defects of the glass epoxy material transparent cover plate prepared in prior art, the present invention proposes following solution, namely a kind of solar panels composite decking of improvement is provided, the solar panels composite decking of described improvement forms antireflection layer and corrosion-resistant coating successively on glass epoxy, described antireflection layer is only made up of a kind of material and has the thickness changed in gradient, and described corrosion-resistant coating is the layer of DLC glassy layer, DLC carbon-coating or DLC glass and the alternately laminated formation of diamond-like-carbon.
Antireflection layer has been widely used in optics glass devices, and its general principle utilizes incident light to cancel out each other to reduce the reflection of incident light at the reverberation of air-anti-reflection film interface and anti-reflection film-glass interface.Under the prerequisite that the glass epoxy refractive index being used as panel is certain, antireflection layer is relevant with the thickness of antireflection layer with the refractive index of antireflection layer constituent material for anti-reflection optical wavelength.If adopt single material to prepare the uniform antireflection layer of thickness, while a certain wavelength light penetration of raising, the transmitance of its wavelength incident light will inevitably be weakened.Based on this principle, by using the constituent material with specific refractive index and controlling the thickness of antireflection layer, can weaken ultraviolet light through, reduce its light aging effect to EVA adhesive film.In order to ensure that the transmitance of visible ray gets a promotion, simultaneously general solution uses multiple filmogen, by the mode of plated film of distributing, form the region that refractive index is different, to ensure that full wave visible ray all can effective light-transmitting panel and arrive solar cell.This film plating process technological process is complicated, production efficiency is low.
Different from scheme disclosed in prior art, antireflection layer preparation technology of the present invention is:
(1) on glass epoxy, form the uniform antireflection layer of a layer thickness.The method that described formation method can use this area conventional, such as chemical vapor deposition (CVD), physical vapor deposition (PVD), middle high-power impulse magnetron sputtering (HPPMS) etc.For ensure visible ray can smoothly through and ultraviolet through by selective weakening, the refractive index of the constituent material of described antireflection layer is preferably between 1.38-1.95, and its maximum gauge (i.e. not etched antireflection layer thickness) is between 55-200nm, preferably 55-95nm, further preferably between 60-80nm.Filmogen is specifically as follows magnesium fluoride, titanium dioxide, tantalum pentoxide, yttria, aluminium oxide etc.
(2) image that etched thickness changes in gradient on the antireflection layer of step (1).Described gradient can be continuous gradient, also can be discontinuous gradient, and the angle simplified from preparation technology is considered, preferred discontinuous gradient.Described image is preferably divided between multiple gradient zones; Preferably there is gap between each gradient zones, this gap is formed by being etched completely by antireflection layer, the preferred 150-450nm in gap, the existence in gap makes glass epoxy directly be connected with corrosion-resistant coating, and antireflection layer is divided into multiple independently interval indivedual interval breakage by corrosion-resistant coating can not cause adverse effect to rest interval.The method that described etching can use this area conventional, such as holographic laser etches (HLE), sputtering and (SIME) is lost in ion beam milling, high pressure plasma etches (HPPE), reactive ion etching (RIE) etc.
Corrosion-resistant coating is positioned at the contrary side with glass epoxy substrate of antireflection layer, play protect antireflection layer and effect.Its constituent material comprises plasma polymer layer, is specifically as follows DLC glass (DLG) or diamond-like-carbon (DLC).
DLC glass (DLG) is the glass substantially in amorphous state be made up of carbon and silicon, can optionally containing hetero atoms such as such as hydrogen, nitrogen, oxygen, fluorine; Diamond-like-carbon (DLC) is formed primarily of carbon atom and hydrogen atom.DLG and DLC molecular structure stabilized, has regular atomic structure, has good rigidity, wearability and corrosion resistance.Using it as corrosion-resistant coating, glass epoxy and antireflection layer and environment can be made effectively to isolate, even if use very thin coating also can effectively prevent sand and dust etc. from scratching the corrosion of glass epoxy/antireflection layer or soda acid etc. to glass epoxy/antireflection layer.
The preparation method of DLG and DLC layer can realize according to method well-known to those skilled in the art, such as, method disclosed in U.S. Patent Application Publication US2007/0020451A1.
Corrosion-resistant coating can comprise one deck DLG or DLC, also can be the multi-layer anticorrosion erosion layer that DLG and DLC is alternately formed.The preferred 100-300nm of thickness of corrosion-resistant coating, further preferred 150-200nm.The metering of described thickness, with the antireflection layer be not etched and corrosion-resistant coating contact surface for starting point, with corrosion-resistant coating and air contact surfaces for terminal.
The concrete steps of the preparation method of the solar panels composite decking of improvement of the present invention are:
(1) cleaning glass steel plate;
(2) the uniform antireflection layer of thickness is formed on glass epoxy;
(3) etch to form thickness gradient to antireflection layer;
(4) above antireflection layer, corrosion-resistant coating is generated.
Wherein, the formation method of antireflection layer is selected from chemical vapor deposition (CVD), physical vapor deposition (PVD), middle high-power impulse magnetron sputtering (HPPMS).Particularly in step (3), antireflection layer can be divided into further by etching the interval that multiple thickness changes in gradient.
Beneficial effect
