Abstract
The invention discloses a kind of three-layer co-extruded composite membrane of high permeability and its application, the high three-layer co-extruded composite membrane of permeability includes following components: internal layer, and the internal layer is ethylene-vinyl acetate copolymer layer；Middle layer, the middle layer are set on the outside of the internal layer, and the middle layer is polyolefin elastomer layer, and the polyolefin elastomer layer includes following components: polyolefin elastomer micelle, 92.5%-98.7% according to parts by weight；Antioxidant, 0.1%-1%；Thermal initiator, 0.5%-2%；Cross-linking monomer, 0.5%-2.5%；Silane coupling agent, 0.1%-1%；Light stabilizer, 0.1%-1%.Outer layer, the outer layer are set on the outside of the middle layer, and the outer layer is ethylene-vinyl acetate copolymer layer.The high three-layer co-extruded composite membrane of permeability has excellent water preventing ability, anti-PID performance and high transparency, laminating temperature is lower, and lamination times it is shorter the advantages that, reduce photovoltaic module production energy consumption and cost, production efficiency and photovoltaic efficiency are improved, can be applied to the photovoltaic glass and cell piece of bonding photovoltaic cell.
Description
Technical field
The present invention relates to the applications of a kind of high three-layer co-extruded composite membrane of permeability and the high three-layer co-extruded composite membrane of permeability.
Background technique
Currently, polyolefin elastomer glue film (POE glue film) due to its excellent water preventing ability and better anti-PID performance just by
Walking substituted ethylene-vinyl acetate adhesive film (EVA adhesive film) becomes main photovoltaic encapsulation glue film.But existing POE glue
Laminating temperature needed for film is higher, and lamination times are longer, and light transmittance is lower than EVA adhesive film, and POE micelle cost is higher than EVA micelle,
Therefore photovoltaic module production energy consumption and cost are improved, reduces production efficiency and photovoltaic efficiency.
Summary of the invention
The present invention is directed at least solve one of the technical problems existing in the prior art.
For this purpose, the present invention proposes a kind of three-layer co-extruded composite membrane of high permeability, which has height
The advantages that transparency, excellent water preventing ability and anti-PID performance, laminating temperature is low, and lamination times are short, reduces photovoltaic module production
Energy consumption and cost, improve production efficiency and photovoltaic efficiency.
The present invention also proposes a kind of application of three-layer co-extruded composite membrane of high permeability, high permeability three according to an embodiment of the present invention
Layer coextrusion-lamination film can be used for photovoltaic encapsulation glue film, and can be applied to the photovoltaic glass and cell piece of bonding photovoltaic cell.
The three-layer co-extruded composite membrane of high permeability according to an embodiment of the present invention, includes following components: internal layer, and the internal layer is second
