Abstract
The present invention provides a kind of photovoltaic backboard and preparation method thereof, the photovoltaic backboard includes four-layer structure, it is respectively to bond film layer, glue layer, middle pet layer and outer layer pet layer, the outer layer pet layer to be mainly made up of the composition of following weight/mass percentage composition from inside to outside：50 52%PET resins, 43 46%PP resins, 0.3 0.5% antioxidant, 2 3% coupling stabilizers, 0.8 1.1% hydrolysis-resisting agent, 0.6 0.8% light stabilizer and 0.1 0.4% fire retardant.The photovoltaic backboard of the present invention has good mechanical performance, good hydrolytic resistance, heat-resisting quantity, ultraviolet ageing performance is obviously improved, and there is good fire resistance, the photovoltaic backboard of the present invention is not fluorine-containing, fluoride pollution is not caused to environment, and its preparation method is simple, suitable for industrial production.
Description
Technical field
The invention belongs to photovoltaic material field, is related to a kind of photovoltaic backboard and preparation method thereof.
Background technology
Increasingly increase with the installation amount of solar photovoltaic assembly, the environmental issue of photovoltaic module increasingly attracts attention.
For solar energy backboard as a close indispensable part in photovoltaic module, the recovery and environmental issue for its fluoropolymer are also standby
It is concerned.
Shown according to national environmental protection department detection data, endemic fluorosis is very wide in China's distribution, according to statistics in photovoltaic
The more area of component installation amount, fluorine poisoning phenomenon are more serious.China is gathered using fluorine-containing more when manufacturing photovoltaic module at present
Compound backboard, due to containing halogens in the polymer, after component is scrapped, fluoropolymer recycling may face
Some are difficult, and the problem of environmental pollution future thus brought will highlight.In view of there is no at present in the industry effective recovery scheme and
Technology, the extremely firm chemical constitution of fluorocarbon, common burial processing method can not all degrade in 1000 in addition
The composition.Simultaneously as fluorine can discharge poisonous and hazardous gas after combustion, so can not also use the method burned to handle.
Therefore, in the art, the best approach to solve the above problems is to develop not fluorine-containing photovoltaic backboard.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of photovoltaic backboard and its preparation side
Method.The photovoltaic backboard of the present invention is not fluorine-containing, environmentally friendly, pollution-free, and combination property is good.
To reach this goal of the invention, the present invention uses following technical scheme：
On the one hand, the present invention provides a kind of photovoltaic backboard, and the photovoltaic backboard includes four-layer structure, by
Interior respectively to bond film layer, glue layer, middle pet layer and outer layer pet layer to outer, the outer layer pet layer is mainly by following quality
The composition of percentage composition is made：
In the present invention, in the preparing raw material of the outer layer pet layer PET resin dosage can be 50%, 50.3%,
50.5%th, 50.8%, 51%, 51.3%, 51.5%, 51.8% or 52%.
In the present invention, in the preparing raw material of the outer layer pet layer PP resins dosage can be 43%, 43.5%,
43.8%th, 44%, 44.3%, 44.5%, 44.8%, 45%, 45.3%, 45.5%, 45.8% or 46%.
In the present invention, in the preparing raw material of the outer layer pet layer antioxidant dosage can be 0.3%, 0.33%,
0.35%th, 0.38%, 0.4%, 0.45%, 0.48% or 0.5%.
Preferably, the outer layer pet layer is mainly made up of the composition of following weight/mass percentage composition：
