Abstract
A kind of enhanced POE photovoltaic encapsulation glue film of the present invention, raw material and raw material weight percentage composition are as follows: POE 40-50%, anti ultraviolet agent 0.1-1%, epoxidized soybean oil 0.1-3%, caprolactam 0.1-3%, silane coupling agent 0.1-3%, reinforced resin 40-60%.The present invention has the characteristics that tensile strength is high, resistance to ag(e)ing is strong, is not easy xanthochromia and long service life.
Description
Technical field
The invention belongs to material science and technology field more particularly to a kind of enhanced POE photovoltaic encapsulation glue films.
Background technique
Photovoltaic module needs to select suitable glue film seal protection cell piece, connecting line and backboard.EVA adhesive film is most common
Glue film, main component is ethylene-vinyl acetate copolymer (EVA), a small amount of crosslinking agent, assistant crosslinking agent, age resister and
Other function additives.EVA is that copolymerization preparation is carried out by two kinds of monomers, and ethylene chain breaks more stable, but vinylacetate segment
In high temperature and humidity, it is easy to happen hydrolysis, light-heat aging reaction causes EVA degradation to generate bubble, and delamination and xanthochromia are existing
As reducing the generated output of light transmittance and component, shortening the service life of component.A kind of EVA resin that can substitute is found to be used in
Become the task of top priority in photovoltaic encapsulation material.
POE is ethylene octene copolymer, is made of saturated aliphatic chain, has good weather-proof, anti-ultraviolet ageing performance, excellent
Different heat-resisting, resistance to low temperature, use temperature range is wide, good light transmittance, excellent electrical insulation capability, and cost performance is high, adds
The features such as work is easy.But POE intensity and adhesive property are lower, are a kind of nonpolar macromolecules, and mechanical property is undesirable etc.
Disadvantage will affect its application in photovoltaic encapsulation glue film.
The method for improving POE intensity at present has POE/ polystyrene blend, and POE/SEBS is blended, and POE/PS/SEBS is blended,
The researchs such as POE/ isobutene-diene rubber regeneration blending, but the light transmittance of prepared material does not reach requirement, and mutually separation etc. occurs and lacks
Sunken, there has been no using enhancing transparent resin and POE modified, addition expanding material raising compatibility prepares enhanced POE photovoltaic envelope
Fill the patent report of glue film.
Summary of the invention
In order to solve the above-mentioned prior art problems, the present invention uses following scheme:
A kind of enhanced POE photovoltaic encapsulation glue film, raw material and raw material weight percentage composition are as follows:
POE40-50%；
Anti ultraviolet agent 0.1-1%；
Epoxidized soybean oil 0.1-3%；
Caprolactam 0.1-3%；
Silane coupling agent 0.1-3%；
Reinforced resin 40-60%.
The present invention has the characteristics that tensile strength is high, resistance to ag(e)ing is strong, is not easy xanthochromia and long service life.
Specific embodiment
Below in conjunction with specific embodiment, the present invention will be described in detail, herein illustrative examples and explanation of the invention
For explaining the present invention, but it is not as a limitation of the invention.
Embodiment
A kind of enhanced POE photovoltaic encapsulation glue film of the present invention, raw material and raw material weight percentage composition are as follows:
POE45%, anti ultraviolet agent 0.5%, epoxidized soybean oil 0.5%, caprolactam 1%, silane coupling agent 2%, reinforced resin
51%.
The above-described embodiments merely illustrate the principles and effects of the present invention, and is not intended to limit the present invention.It is any ripe
The personage for knowing this technology all without departing from the spirit and scope of the present invention, carries out modifications and changes to above-described embodiment.Cause
This, institute is complete without departing from the spirit and technical ideas disclosed in the present invention by those of ordinary skill in the art such as
At all equivalent modifications or change, should be covered by the claims of the present invention.
