Background technology
In view of the scarcity increasingly of non-renewable natural resources such as oil, coal, natural gas and ocean ice, again in view of the mankind
To the economy consciousness of natural resources and being obviously enhanced of protective awareness, to inexhaustible and have the feature of environmental protection and
The utilization of cheapness resource such as wind energy and solar energy is paid attention to increasingly, solar energy ground in the mankind's sustainable use energy strategy
Position shows day by day.Along with the fast development of BIPV, two-sided photovoltaic electrification component etc., transparent solar cell backboard
Application more and more extensive, its performance requirement is more and more higher.Except need to meet electric insulating quality that Normal back plate has, hinder wet
Outside performance and weatherability, transparent solar energy backboard also needs to the performances such as uvioresistant performance and the high transmission rate of excellence.
Existing transparent solar backboard product is mainly transparent type PET class backboard, and such backboard is through after a while
Hydrothermal aging (85 DEG C of * 85%RH) after, it may appear that xanthochromia value increase, PET is hidden splits the situations such as embrittlement, exist weatherability difference lack
Fall into.For improving weatherability and the light transmittance of transparent type backboard, existing technical scheme is typically will have containing of good weatherability properties
Fluoropolymer material is compound or is applied to baking and curing in PET base material and constitutes painting membranous type transparent back panel.As practical in China new
Type license notification number CN201979775U describes " a kind of transparent coating back plate ", and fluorine-containing coat is coated on transparent PET
The surface of base material, thus obtained backboard has good weatherability, light transmittance advantages of higher, but its product cost is high, and makes
The problems such as backboard delamination it are susceptible to during with.And for example China utility model Authorization Notice No. CN204045606U recommends
" a kind of solar photovoltaic battery component transparent back panel composite membrane ", uses transparent PC(Merlon) thin film replacement fluoropolymer
Material is bonding by transparent glue with clear PET film, thus obtained transparent back panel low cost, and can improve photovoltaic
The generated energy of assembly, but the resistance to irradiation of its product penetrates poor-performing, shortens the service life of solar module.
In view of above-mentioned prior art, it is necessary to the structure of existing transparent solar backboard is improved.To this end, this
Applicant has made useful design, and technical scheme described below produces under this background.
Summary of the invention
The purpose of this utility model is to provide a kind of transparent solar backboard, has the weatherability of excellence, ageing-resistant
Property, radiation resistance and insulating properties, and light transmittance is high, can meet the demand of two-sided photovoltaic electrification component.
The purpose of this utility model is such to reach, a kind of transparent solar backboard, it is characterised in that: include base
Layer, weathering layer and internal layer, described basic unit is combined into weathering layer towards a side surface of weathering layer by the first tack coat
Integrally, and basic unit is combined as a whole towards a side surface of internal layer by the second tack coat and internal layer, and described basic unit is transparent
Mylar, described weathering layer and internal layer are clear fluorocopolymers layer, the first described tack coat and the second tack coat
It is transparent glue tack coat.
In a specific embodiment of the present utility model, described transparent polyester film is poly terephthalic acid second two
Any one in alcohol ester film, polybutylene terephthalate thin film or PEN thin film.
In another specific embodiment of the present utility model, described clear fluorocopolymers layer is by fluorine-containing copolymerization
The copolymer layer that thing, plexiglass and auxiliary agent are made.
In another specific embodiment of the present utility model, described fluorinated copolymer by politef and/or
Polyvinylidene fluoride and/or polyvinyl fluoride are made.
In another specific embodiment of the present utility model, described auxiliary agent is light stabilizer and/or uv absorption
Agent and/or the combination of antioxidant.
This utility model is combined weathering layer and internal layer respectively on two surfaces of basic unit and constitutes multi-layer compound structure, institute
The multi-layer compound structure stated has good weatherability, resistance to ag(e)ing, radiation resistance and insulating properties, and stain resistance is strong, water
Vapour transmitance is little, and service life was up to more than 25 years；Further, since employing transparent polyester film is as basic unit, and use transparent
Fluorinated copolymer layer is as weathering layer and internal layer, thus has higher light transmittance, can meet making of two-sided photovoltaic electrification component
Use demand.
