Description
Technical field
The invention belongs to technical field of solar utilization technique, anti-particularly to a kind of low-cost solar thin film
Penetrate mirror material.
Background technology
At present, the universal cost depending on Solar Energy Heat Utilization System of solar thermal utilization.Due to too
The low-density feature of sun energy, is produced high-temperature hot by solar energy, it is generally required to sunlight is carried out optically focused,
What Technical comparing was ripe at present has trench light condensing system, disc type condensation system and tower condenser system.Groove
Formula condenser system is mainly used in solar light-heat power-generation and produces industrial steam, and photo-thermal power generation is temperature required
More than 450 degree, and industrial steam is temperature required between 100-300 degree.Slot light collection system at present
System, owing to its system cost is higher, causes its system investments cost recovery longer, it is difficult to by common
Industrial undertaking is accepted.
The system cost of slot light collection is mainly made up of thermal-collecting tube, reflecting mirror and tracker etc..Reach
High temperature, it is necessary to high light concentrating times, the reflecting mirror area of corresponding condenser system will be big,
And reflecting mirror is little by the deformation conducted oneself with dignity and wind load is caused, otherwise light can deviate from thermal-collecting tube,
Do not reach the purpose of light and heat collection.Reflecting mirror has glass reflector, aluminum base reflecting mirror and thin film anti-at present
Penetrating mirror material, the production of glass reflector and aluminum base reflecting mirror needs to consume substantial amounts of fossil energy, thin
The power consumption of film reflecting mirror material is much smaller；The problem that film reflecting mirror material is primarily present is its weatherability
Problem, it is the highest that it solves cost.
Reflecting mirror Coating Materials uses silver to be more suitable for the reflection of sunlight, past than the reflectance using aluminum
Mainly solve is the problems such as the surface tear of organic film, weatherability and uvioresistant, but these problems
The product of the aluminum reflector thin film in past obtains part solve, such as United States Patent (USP)
Disclosed in US4307150.The such as fluorine-contained film of new material now etc., its weatherability and uvioresistant
Ability can use 30 years, and it is the most a lot of that surface Hardening processes material, it is easy to solves film surface
Scuffing problem.But there are two problems in silver coating, organic protection on first silvering surface is thin
Mostly there is air-and water-permeable rate more or less in film, so can corrode silver layer so that silvering surface
Reflectance reduction, it two is that silverskin has a transmission window to ultraviolet light (324nm), such as Fig. 6 a-
Shown in Fig. 9, Fig. 6 a, Fig. 7 a are reflectance curves, and corresponding transverse axis represents optical wavelength, longitudinal axis table
Showing reflectance, what Fig. 6 b, Fig. 7 b, Fig. 8, Fig. 9 represented is transmittance curve, permissible from figure
Finding out, in the case of the most silver-plated, reflectance is when silver layer reaches certain thickness, and reflectance is permanent
Fixed the most constant, and through the wavelength of ultraviolet light of silver layer near 324nm, its transmitance is along with silver layer
Thickening and reduce, but its cost correspondingly increases, and effect bad.The ultraviolet light meeting of transmission
The substrate organic membrane and the gum that make the silver back side produce aging, and its result is to produce a lot of bubbles, broken
The planarization of bad minute surface.Such as United States Patent (USP) US6989924B1 just discloses solution, and it is main
It is the ultra-violet absorption thin film increasing multilamellar on the surface of silver, simultaneously works as anticorrosive and anti-ultraviolet
Purpose.As it is shown in figure 1, include back adhesive protecting film 1, this layer of protection when in use will be removed,
Gum layer 2, for reflective film material is bonding with backboard (not drawing in figure), coating material
3, PET film etc., mirror layer 4 can be used, generally use aluminum or silver as coating material,
Being completed by vacuum evaporation or the technique such as magnetron sputtering or coating, its thickness is typically at 80-120nm
Left and right.Protective clear layer 5, for blocking the corrosion to metal coating layer of air and steam, typically adopts
With the weatherability gentle water blocking preferable material of rate, such as fluorine-contained film, but the price of this thin film
The highest, and its price is directly proportional to thickness.In order to reduce cost, this layer of protecting film is generally by 2
The Film laminated composition that layer is above, as shown in Figures 2 and 3, protective clear layer 5a, 5b, 5c this
A little thin film collectively constitute the protecting film that air water blocks and weatherability is good.For ultraviolet blocking-up, need
Interpolation UV absorbent in the material of 5b, 5c, but UV absorbent, employing one
After the section time, film surface can be made to turn to be yellow, and affect the light transmission of thin film so that the light of reflecting mirror
Learn hydraulic performance decline, and the cost of do so is the highest, and have has been even more than glass reflector
Cost.United States Patent (USP) US8398252 discloses and prevents silver coating to be corroded when producing and use later
Method, mainly at the back side of silver coating one layer of 10nm titanium (Ti) of plating or chromium (Cr), then
The yttrium fluoride (YF3) that Ti one layer of 5nm of upper plating is thick, in order to silver layer is easily deposited into cause on yttrium fluoride

There is the gas of corrosiveness.But Ti or Cr layer is the highest to the transmitance of ultraviolet light, it is difficult to completely
Cut off ultraviolet light and substrate organic membrane and the gum at the back side are produced aging, and the barrier layer of silver surface is complete
The full method by vacuum coating is difficult to the effect reached, this is because the thickness of vacuum coating is usually
Nano level, and general film plating layer is to have certain breathability, and i.e. these film plating layers are for gas
It is not fine and close for body.Under conditions of outdoor application, in the condition that temperature humidity is continually changing
Under, silver layer still can corrode, thus reduces the performance of reflecting mirror.United States Patent (USP) US7612937B2
