Abstract
The utility model discloses a PET (polyethylene terephthalate) composite membrane being used for photovoltaic assembly encapsulation and adopting a three-layer structure. The composite membrane is formed by attaching and pressing composition of a modified EVA (ethylene-vinyl acetate copolymer)/POE (polyolefin elastomer) thin membrane and two sides of a PET base material membrane. A technology of the composite membrane comprises the steps as follows: functional flame-retardant EVA/POE resin modified by an antioxidant is fused and extruded by an extruder and then composited with the two sides of the PET base material membrane in an attached and pressed manner to obtain the (EVA and POE)/PET/(EVA and POE) composite membrane adopting the three-layer structure. The composite membrane is simple in processing technology, low in cost, excellent in flame retardance and mechanical property and good in barrier property, heat resistance, electric insulation property and ageing resistance, can be directly used as a connecting layer for bonding of a back plate and a cell and has a potential application as a photovoltaic assembly encapsulation material.
Description
Technical field
The utility model relates to laminated film technical field, specifically refers to a kind of PET composite membrane for photovoltaic component encapsulating with three-decker.
Background technology
Along with people more and more pay attention to awareness of safety, especially fire resistance is had higher requirement, therefore, by giving photovoltaic back film high-grade fire resistance, the development of photovoltaic industry is significant.Solar cell uses for a long time under hot environment, and through the phenomenon of long-term direct projection meeting generation backboard burning, therefore other composite membrane of flame retardant grade is widely used at photovoltaic industry.
At present, polyolefin elastomer (polyolefin elastomer) is (POE) thermoplastic elastomer (TPE) with narrow molecular weight distribution and uniformly short-chain branch distribution of DOW chemical company of the U.S. taking metallocene as catalyst.High and single being uniformly distributed of its comonomer octene content, narrow molecular weight distribution, these characteristics have given POE resin good material property.In POE molecular resin, do not contain unsaturated double-bond, the toughness with good heat endurance, weatherability, resistance to ag(e)ing, brilliance has good processability simultaneously.EVA glued membrane is the material that is mainly used at present encapsulating solar cell, but it comes with some shortcomings, and as aging in easy xanthochromia, weatherability is poor, service life is short.
Utility model content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provide a kind of processing technology simple, cost is low, there is good anti-flammability and mechanical property, and good barrier, heat resistance, electrical insulating property and resistance to ag(e)ing, and long service life has the PET composite membrane of three-decker for photovoltaic component encapsulating.
To achieve these goals, a kind of PET composite membrane for photovoltaic component encapsulating with three-decker described in the utility model, this composite membrane carries out pressing by the two sides of modified EVA/POE film and PET base material film and is composited.
Optimally, the functional fire-retardant EVA/POE resin of described modified EVA/POE film after by antioxidant modification melt extruded and formed by extruder.
Optimally, described PET base material film thickness is 15 μ m-30 μ m.
Optimally, modified EVA/POE film thickness is 5 μ m-10 μ m.
The beneficial effects of the utility model are:
Compared with prior art, the PET composite membrane for photovoltaic component encapsulating with three-decker described in the utility model, processing technology is simple, cost is low, there is good anti-flammability and mechanical property, and good barrier, heat resistance, electrical insulating property and resistance to ag(e)ing, can, directly as the articulamentum of bonding backboard and cell piece, there is potential application as photovoltaic component encapsulating material.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
A kind of PET composite membrane for photovoltaic component encapsulating with three-decker described in the utility model, this composite membrane is that two sides that modified EVA/POE film 2 and the thickness of 15 μ m-30 μ m is the PET base material film 1 of 5 μ m-10 μ m is carried out pressing and is composited by thickness.
A preparation technology for photovoltaic component encapsulating with the PET composite membrane of three-decker, it mainly comprises the following steps:
(1) modified EVA/POE resin is standby: respectively EVA resin, POE resin are mixed through high speed mixer with phosphorous acid bisphenol-A ester solution, then through oven for drying solvent;
(2) PET base material film surface preparation: PET base material film carries out surface treatment through corona and AC agent primary coat, the cohesive force of increase base material and composite bed;
(3) PET base material film and modification POE glued membrane are compound: modified EVA/POE resin that step (1) is obtained is melt extruded and obtained EVA/POE film by extruder, to carry out pressing through the two sides of corona, primary coat surface-treated PET base material film compound with step (2) again, finally pass through ozone Oxidation Treatment, the peel strength that further strengthens base material and composite bed, obtains (EVA & POE)/PET/ (EVA & POE) laminated film.
The utility model provides a kind of thinking and method for photovoltaic component encapsulating with the PET composite membrane of three-decker, and method and the approach of this technical scheme of specific implementation are a lot, and the above is only preferred embodiment of the present utility model.
