The polymer base material of the intermediate non-transparent layer contains inorganic pigment powder. Through using the first transparent layer, the intermediate non-transparent layer and the second transparent layer of specific components, a problem that the packaging glue film is easy to overflow (flange) can be solved; and a purpose of controlling a shrinking percentage can be achieved, a laminated assembly appearance is good and finally generation power is increased.

Description

A kind of packaging adhesive film good without flange bonding
Technical field
The invention belongs to area of solar cell, is related to a kind of packaging adhesive film used for solar batteries, and in particular to Yi Zhongwu Flange peels off good packaging adhesive film.
Background technology
Since being born from life on earth, the just main infrared radiant energy existence provided with the sun, and also understand from ancient human With sun dry part, and the method as food is made, such as salt manufacturing and solarization cured fish.In the situation that fossil fuel is reduced increasingly Under, solar energy has become the mankind and has used the important component part of the energy, and is constantly developed.
Because solar cell is in outdoor application, bad environments, it is therefore desirable to protected.Be usually used glass, The structure such as packaging adhesive film and backboard is encapsulated.The effect of packaging adhesive film is while solar cell is encapsulated, to incite somebody to action Glass and backboard are coupled together, and the glued membrane is crosslinked during lamination of solar battery components, by the same of solar cell package When glass and backboard are coupled together.For solar module, packaging adhesive film between cell piece and backboard is simultaneously not required to Light transmittance that will be very high, but preferable adhesive property is needed, while to have excellent weatherability.At present big multicompartment factory exists The transparent EVA glued membrane for using up and down of cell piece, this may reduce the reflectivity of backboard side, and then reduce the output of cell piece Power.In order to solve the problem, there are production white EVA packaging adhesive films to replace original transparent EVA packaging plastic currently on the market Film, but easily appearance is bonding with backboard loosely in lamination process for pure white EVA packaging adhesive films, and backboard is layered with EVA Problem;In addition, in lamination process, EVA melt-flows have partial white EVA and overflow to cell piece front, so can lead Cause cell piece part to be blocked, can equally reduce the power output of component.
The content of the invention
The invention aims to overcome the deficiencies in the prior art and provide a kind of packaging adhesive film good without flange bonding.
To reach above-mentioned purpose, the technical solution adopted in the present invention is:A kind of packaging adhesive film good without flange bonding, It includes the first hyaline layer, middle non transparent layer and the second hyaline layer for setting gradually, and first hyaline layer, the centre are non- Hyaline layer and second hyaline layer are independently of one another the polymeric substrate that EVA, POE or POE mix with LDPE;In described Between non transparent layer polymeric substrate in also contain inorganic pigment powder.
Optimally, the polymeric substrate of first hyaline layer and second hyaline layer is independently of each other comprising following heavy The component of amount fraction:
POE 80~100%;
LDPE 0~20%.
Further, first hyaline layer and second hyaline layer are also included independently of each other and account for its polymeric substrate The component of following weight fraction:
Optimally, component of the polymeric substrate of the middle non transparent layer comprising following weight fraction:
POE 70~90%;
LDPE 0~20%;
Inorganic pigment powder 0~10%;
The inorganic pigment powder be titanium dioxide, carbon black, di-iron trioxide, silica, lithopone, chrome yellow, chrome oxide green, Barba hispanica, aluminium powder or copper powder etc..
Further, the middle non transparent layer is also comprising the component for accounting for the following weight fraction of its polymeric substrate:
Because above-mentioned technical proposal is used, the present invention has compared with prior art following advantages:The present invention is viscous without flange The good packaging adhesive film of knot, by the first hyaline layer using specific components, middle non transparent layer and the second hyaline layer, such energy Enough solve easy overflow (flange) problem of packaging adhesive film;The purpose of control shrinkage factor can be played, laminated compenent outward appearance is good, and It is final to improve generated output.
