In addition, in the aforementioned resin layer, during the compounding titanium dioxide, with respect to the resin bed total amount, the compounding rate is 20 ~ 80 % by weight.Can think that now resin bed, particularly mylar heat to carry out biaxial stretch-formed, so the interval of titanium dioxide cross-linked resin is different from white layer, can not hinder ultraviolet incident white layer.
In addition, the aforementioned resin layer can also contain adjuvant etc. except vibrin, as such adjuvant, can enumerate hydrolysis modifier, solid phase promoter, antioxidant, fire retardant etc.
In addition, reflecting plate of the present invention, in the scope of the mist degree that does not affect the aforementioned resin layer, can also form adhesive linkage between aforementioned white substrate and aforementioned white layer, between aforementioned white layer and aforementioned resin layer or at the surface-coated bonding agent of aforementioned resin layer.Thus, can increase the bonding force of aforementioned white substrate and aforementioned white layer or aforementioned white layer and aforementioned resin layer, or while stating before use reflecting plate as the used for solar batteries backboard, can easily make the encapsulant of this reflecting plate and solar module bonding.As such bonding agent, preferably use polyurethanes bonding agent, isocyanates bonding agent.As such polyurethanes bonding agent, such as enumerating: the SEIKABOND(registered trademark) E-263, SEIKABOND C-26(are above is industry (strain) manufacture of refining large day), the TAKELAC(registered trademark) A3210, TAKENATE(registered trademark) A3072 etc. (above is Mitsui Chemicals Polyurethanes, and Inc. manufactures).In addition, as the isocyanates bonding agent, such as using the CORONATE(registered trademark) commercially available product of L etc. (NIPPON POLYURETHANE INDUSTRY CO., LTD. manufactures).In addition, in these polyurethanes bonding agents, isocyanates bonding agent, not to producing in cementability, serviceable life in dysgenic scope, can the compounding catalysts, other adjuvants.
The thickness of reflecting plate of the present invention can freely be adjusted according to its purposes.For example, when using this reflecting plate as the backboard of crystal-type solar cell, its preferred gross thickness is 250 μ m ~ 350 μ m.
Such reflecting plate is for example manufactured by the following method.
In the present embodiment, the film that use consists of PEN is as aforementioned white substrate.As making the method that contains Chinese white in the PEN film, be not particularly limited, can adopt existing method.For example, can enumerate the method for adding Chinese white in any stage of manufacturing the PEN composition.In addition, preferably in Esterification Stage, add, or also can after ester exchange reaction finishes, add and carry out polycondensation reaction.In addition, can use the mixing extruder of band ventilating opening (bent) to carry out blend to slurry and the polyester raw material that is dispersed in the Chinese white in ethylene glycol or water etc.In addition, can be also to use mixing extruder dried Chinese white and polyester raw material to be carried out to the method for blend.
Then, such PEN is melted, use the curtain coating drum to make its cooling curing, form non-stretched film.Then, this non-stretched film is stretched along its length more than 1 time or 2 times under 121 ℃ of glass transition temperature Tg ~ (Tg+60) ℃, the stretching ratio that makes its total is 3 ~ 6 times.And then, then take mode that stretching ratio is 3 ~ 6 times by its Tg121 ℃ ~ (Tg+60) a ℃ lower broad ways stretches, and makes the PEN film of thickness 250 μ m.In addition, can also be as required to this film 180 ℃ ~ 230 ℃ thermal treatments of carrying out for 1 ~ 60 second.
Then, on the face of the described white layer of formation of above-mentioned white substrate (film), the mode that the thickness of take is 30 μ m is coated with the white resin composition that comprises thermoplastic resin, titanium dioxide, aluminium hydroxide and isocyanate compound that is adjusted into the viscosity that is suitable for coating with organic solvent.Thereafter, at the temperature of 70 ℃ ~ 90 ℃, make organic solvent volatile dry contained in said composition, formation is filmed.As the coating process of white resin composition, can suitably use silk screen print method, curtain to be coated with method, spraying process, rolling method etc.In addition, the volatile dry of organic solvent is used heated air circulation type drying oven, IR stove, hot plate, convection oven etc., 80 ℃ ~ 200 ℃ under heat film, make its heat curing, can be produced on aforementioned substrates thus the reflecting plate that is formed with white layer thereafter.
In addition, also can use the dry film formed by said composition to form aforementioned filming, but not as described above the white resin composition is coated on aforementioned white substrate.
Such dry film is such as obtaining as follows: on the carrier film formed by polyethylene terephthalate etc., coating white resin composition drying form the white resin layer, then diaphragms such as stacked strippable polyethylene film, polypropylene film thereon.Particularly, this white resin layer by utilizing knife type coater, lip coating machine, comma coating machine, film be coated with the coating white resin composition such as machine, the excellent coating machine of silk, nick version coating machine and be dried and form equally with above-mentioned on carrier film.
Then, peel off the diaphragm of this dry film, this white resin layer and aforementioned white substrate is overlapping, and use laminating machine etc. are by they laminatings, thereby formation white resin layer films on aforementioned white substrate.Then, as long as this is filmed and is similarly heated with above-mentioned, just can on aforementioned substrates, form white layer.
In addition, as other embodiments, while forming resin bed on aforementioned white layer, on the aforementioned white layer of the reflecting plate by making with above-mentioned same step, form resin bed.
As such resin bed, for example can use the PEN film.As the manufacture method of such PEN film, for example use the curtain coating drum to make molten PEN cooling curing, form non-stretched film.Then, this non-stretched film is stretched along its length more than 1 time or 2 times under 121 ℃ of glass transition temperature Tg ~ (Tg+60) ℃, the stretching ratio that makes its total is 3 ~ 6 times.And then, then take mode that stretching ratio is 3 ~ 6 times by its Tg121 ℃ ~ (Tg+60) a ℃ lower broad ways stretches, and makes the PEN film of thickness 50 μ m.In addition, can also be as required to this film 180 ℃ ~ 230 ℃ thermal treatments of carrying out for 1 ~ 60 second.
Then, at surface binded or the aforementioned PEN film of crimping (resin bed) of this white layer, make thus the reflecting plate of another embodiment.As this adhering method, carry out on the surface that roller group who heated by use etc. is connected on aforementioned white layer by aforementioned PEN film hot-pressing.
As another embodiment again, also can form white layer and aforementioned white substrate thermo-compressed is manufactured to reflecting plate of the present invention on the surface of this white layer by the surface at aforementioned PEN film.
In addition, except aforementioned embodiments, also can use the interlayer laminating of extruding from the white resin composition to extruding layer prestack between aforementioned white substrate and aforementioned PEN film (resin bed) that state to manufacture reflecting plate of the present invention.
Then, use the reflecting plate of Fig. 1 simple declaration an embodiment of the invention.
