Abstract
The invention discloses a novel solar backboard. The solar backboard has a three-layer structure consisting of a polyvinylidene fluoride (PVDF) fluorine-containing film, a polycarbonate (PC) resin composite film and a polyethylene (PE) film, wherein the PC resin composite film comprises the following components in part by weight: 50 parts of PC resin, 32 parts of acrylonitrile-butadiene-styrene (ABS) resin, 14 parts of polymethyl methacrylate (PMMA) resin, 0.4 part of antioxidant, 3 parts of coupling stabilizer and 0.6 part of light stabilizer. According to the solar backboard, only one layer of fluorine-containing film is used, so that cost is low, and a component can have the service life of 25 years; and the solar backboard has an obvious market advantage compared with the conventional triphenyltin (TPT) backboard.
Description
Technical field
The present invention relates to a kind of new type solar energy backboard that is used on the solar components.
Background technology
At present, the whole world has all got into global traditional energy (oil, matchmaker and the natural gas) epoch in short supply, and bioenergy all can exhaust within this century.Japan's nuclear leakage explanation nuclear energy less stable, thereby, be that the clean energy resource of representative has obtained great development space with solar energy and wind energy etc.
Various countries all formulated the policy of helping solar energy, and global solar power plant installation has reached 26GW in 2011.The basic original paper of solar power plant is exactly a solar components, and solar components is made up of glass, silicon chip, EVA, backboard etc.Wherein, the solar energy backboard plays a part to protect solar components to exempt from large natural environments such as steam, ultraviolet, temperature and frost.A qualified solar energy backboard will guarantee that at least solar components has the useful life in 25 years.
Modal on the market solar energy backboard is exactly the TPT structure, and wherein, T is meant the PVF fluoropolymer membrane (TEDLAR) of E.I.Du Pont Company, and P is meant PET.This kind product applicating history at most, product quality is also reliable.Because TPT adopts two-layer fluoropolymer membrane folder one deck PET, fluoropolymer membrane is the most effectively material of keeping out environmental factors such as steam, ultraviolet.Because of the PVF fluoropolymer membrane belongs to E.I.Du Pont Company's technical monopoly; And E.I.Du Pont Company's production capacity is limited; Can not satisfy backboard demand on the market, a lot of companies adopt pvdf membrane one after another, and fluoropolymer membranes such as ETFE film substitute the PVF fluoropolymer membrane and produce the solar energy backboard; Through practice test, though this film can satisfy the user demand in 25 years.But,,, be unfavorable for the reduction of solar components cost so cause using the solar energy backboard of double-deck fluoropolymer membrane to cost an arm and a leg because the cost of fluoropolymer membrane is very high.Use the individual layer fluoropolymer membrane no doubt can significantly reduce cost, but solar components useful life that can ensure generally about 15 years, can't satisfy the instructions for use in 25 years.
More and more require today of reducing cost at solar product, using the individual layer fluoropolymer membrane is trend of the times, so, invent a kind of one deck fluoropolymer membrane that promptly only uses, and the solar energy backboard that can satisfy 25 year useful life again is a current industry urgency problem to be solved.
Summary of the invention
In order to overcome the problem that exists in the above-mentioned prior art, the purpose of this invention is to provide a kind of one deck fluoropolymer membrane that promptly only uses, cost is lower, and can satisfy the solar components new type solar energy backboard in useful life again.
Technical scheme of the present invention is: a kind of new type solar energy backboard is provided, and said solar energy backboard is made up of following three-decker: PVDF type fluoropolymer membrane, PC resin compounded film and PE film, and wherein, PC resin compounded film is made up of the composition of following weight parts,
PC resin: 50 parts
ABS resin: 32 parts
PMMA resin: 14 parts
Oxidation inhibitor: 0.4 part
Coupling stabilizer: 3 parts
Light stabilizer: 0.6 part.
As to improvement of the present invention, the thickness of said PVDF type fluoropolymer membrane can be 25 microns, and the thickness of said PC resin compounded film can be 150 microns, and the thickness of said PE film can be 50 microns.
Solar energy backboard of the present invention only uses one deck fluoropolymer membrane, and cost is lower, but but can play the effect in 25 year useful life of protection assembly, compares with existing TPT backboard to have the tangible market advantage.
Embodiment
Solar energy backboard of the present invention mainly is made up of following three-decker:
Ground floor (aging-resistant layer): 25 microns of PVDF type fluoropolymer membranes
The second layer (insulation and barrier layer): 150 microns of extraordinary PC resin compounded films
The 3rd layer (with the EVA tack coat): 50 microns of extraordinary PE films
The core of this invention is second layer insulation and barrier layer.The second layer that the tradition backboard is used is the PET film; Only play the effect of insulation; And the second layer of the present invention uses is extraordinary PC resin compounded film, except insulating, also can play the effect of suitable obstruct steam; The 3rd layer of PE film then can improve the cohesive force with EVA greatly, makes to be applied in the solar components more reliably.The solar energy backboard that these three kinds of structures are combined with each other and form can play the effect in 25 year useful life of protection solar components.Suitable with two-sided fluoropolymer membrane material.
PC resin compounded film among the present invention mainly is grouped into by following one-tenth:
PC resin (Merlon): 50 parts;
ABS resin (acrylonitrile-butadiene-styrene copolymer): 32 parts;
PMMA resin (gathering methyl-acrylic resin): 14 parts;
Oxidation inhibitor: 0.4 part;
Oxidation inhibitor can adopt a kind of among BHA, BHT and the PG;
Coupling stabilizer: 3 parts;
The coupling stabilizer can adopt a kind of in HRP and the aluminium titanium compound;
Light stabilizer: 0.6 part;
Light stabilizer HALS, the rare earth light stabilizer
Above composition through mix, heat, extrude, technologies such as moulding and stretching form PC resin compounded film.
PC resin compounded film and PVDF type fluoropolymer membrane and PE film are processed solar energy backboard of the present invention through coating technology such as compound.
The solar energy backboard of this invention, compared with existing two-sided fluoropolymer membrane solar energy backboard (TPT), main advantage is that cost is significantly reduced, useful life is suitable with the TPT backboard simultaneously.
Through comparison and detection, its performance comparison is following:
Can find out that from last table each item indication of the present invention all meets or exceeds the backboard of existing TPT structure.Can substitute existing TPT backboard fully and use, and lower than the cost of existing TPT backboard, the advantage that raw material is easy to get.
