Abstract
The utility model discloses a PTFE double-sided coating backplane. The PTFE double-sided coating backplane includes an outer protective coating, a PET material layer and an inner protective coating, wherein the outer protective coating is a PTFE coating, and the inner protective coating is a fluorine-contained resin PET protective coating; and the PTFE coating and the fluorine-contained resin PET protective coating are directly bonded with two opposite surfaces of the PET material layer. The PTFE coating is advantageous in high humidity, high hardness, scratch resistance, long service life and the like, and the PTFE coating is a thermoplastic plastic with best comprehensive properties currently, and has a special protection ability in the aspect of chemical substances attack prevention, and further, the PTFE coating can isolate water vapor and block ultraviolet rays, and can effectively protect PET materials from being attacked from any chemical substances; the fluorine-contained resin PET protective coating is directly coated on the PET materials, and one adhesive layer can be decreased, and the fluorine-contained resin PET protective coating can be well bonded with the PET materials, and can be also well bonded with EVA materials, and can further protect the PET materials from being aged and damaged from the ultraviolet rays.
Description
Technical field
The utility model relates to technical field of solar batteries, particularly relates to a kind of PTFE coated on both sides backboard.
Background technology
At present solar energy backboard is general adopts five layers of compound structure to process, and comprises PVDF layer, PET material layer, strengthening PE layer and for PVDF layer and PE layer are sticked to respectively to two surperficial tack coats of PET material layer.There are the following problems for above-mentioned solar energy backboard: the one, adopt double face binding layer, and cost is high, processes more loaded down with trivial detailsly, and rate of finished products is relatively low; The 2nd, be subject to the restriction of material self character, the anti-chemical attack ability of surperficial PVDF, makes solar energy backboard easily be subject to the infringement of chemical substance.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of PTFE coated on both sides backboard, can solve the problem that current solar energy backboard exists.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of PTFE coated on both sides backboard is provided, comprise: outer protective finish, PET material layer and interior protective finish, described outer protective finish is PTFE coating, described interior protective finish is fluorine resin PET protective finish; Described PTFE coating and described fluorine resin PET protective finish respectively directly the surface relative with two of described PET material layers bond.
In preferred embodiment of the utility model, the thickness of described PTFE coating is 20 μ m.
In preferred embodiment of the utility model, the thickness of described PET material layer is 250 μ m.
In preferred embodiment of the utility model, the thickness of described fluorine resin PET protective finish is 10 μ m.
The beneficial effects of the utility model are: a kind of PTFE coated on both sides of the utility model backboard, and compared with prior art, tool has the following advantages:
1) external protection PTFE(Poly tetra fluoro ethylene ptfe, polytetrafluoroethylene) coating is new generation of green environmental protection coating material, have that humidity is high, the advantage such as hardness is large, damage resistant and long service life, it is current comprehensive best thermoplastics, aspect chemically resistant material invasion and attack, there iing special protective capability, play the effects such as isolation steam and shielding of ultraviolet, can effectively protect PET material to avoid the invasion and attack of any chemical substance;
2) fluorine resin PET protective finish is directly coated on PET material, reduces one deck tack coat, and existing have good binding ability with PET material, has again with EVA material and have good adhesive property, in addition, can also protect PET material to avoid ultraviolet aging damage.
Accompanying drawing explanation
