Abstract
The invention discloses a solar cell packaging glue film containing EVA (ethylvinylacetate), an ultraviolet absorber, an ultraviolet stabilizer, an antioxygen, an anti-yellowing agent, a cross-linking agent and a coupling agent. The solar cell packaging glue film has high light transmittance and can improve the light utilization of a solar cell; moreover, the solar cell packaging glue film has high EVA crosslinking degree, strong compression resistance, strong resistance against expansion caused by heat and contraction caused by cold, strong ultraviolet radiation resistance and strong heat resistance, therefore the solar cell packaging glue film has a very long service life and can meet the long-term use requirement of the solar cell.
Description
Technical field
The present invention relates to a kind of packaging adhesive film for solar cell, particularly relating to vinyl-vinyl acetate copolymer (EVA) is the packaging adhesive film for solar cell of main raw material.
Background technology
Solar cell stacks the back pressing in order by toughened glass, packaging adhesive film, battery sheet, packaging adhesive film and TPT backboard five layer materials and forms.
Packaging adhesive film for solar cell is main raw with EVA, and that EVA has is transparent, soft, hot melting cohesion property is arranged, melt fluidity good etc. characteristics; These characteristics have satisfied the demand of glued membrane manufacturing and solar cell package, but its poor heat resistance, the ultra-violet radiation resisting ability; Be prone to extend, elasticity is low, and cohesive strength is low; Creep resistance is poor; Be prone to expand with heat and contract with cold, thereby influenced the work-ing life of packaging adhesive film for solar cell, will carry out modification to satisfy the requirement of solar cell life-time service to EVA for this reason.
Summary of the invention
The purpose of this invention is to provide a kind of durable in use, packaging adhesive film for solar cell that solar energy utilization ratio is high,, adopted following technical scheme in order to reach this purpose:
A kind of packaging adhesive film for solar cell; Contain EVA, UV light absorber, UV stabilizer, oxidation inhibitor, anti-xanthochromia agent, linking agent and coupling agent; Said packaging adhesive film for solar cell middle-ultraviolet lamp absorption agent is a UV-531, and its quality is 0.2% ~ 1.0% of an EVA quality;
The content of vinyl-acetic ester is 25% ~ 35% among the said EVA;
Said linking agent is the own ester of tert-butyl hydroperoxide carbonic acid-2-, and its quality is 0.5% ~ 2.0% of an EVA quality;
Said UV stabilizer is 3, the positive hexadecyl ester of 5-di-tert-butyl-4-hydroxybenzoic acid, and its quality is 0.2% ~ 0.5% of an EVA quality.
Said inhibitor is a pentanoic, and its quality is 0.1% ~ 0.5% of an EVA quality.
Said anti-xanthochromia agent is a 2,6 di tert butyl 4 methyl phenol, and its quality is 0.1% ~ 0.5% of an EVA quality.
Said coupling agent is a γ-An Bingjisanyiyangjiguiwan, and its quality is 0.5% ~ 1.5% of an EVA quality.
The invention has the advantages that: packaging adhesive film for solar cell; Contain EVA, UV light absorber, UV stabilizer, oxidation inhibitor, linking agent and coupling agent; Said packaging adhesive film for solar cell light transmission rate is strong, can improve the utilization ratio of solar cell to light; The EVA crosslinking degree is high, and anti-pressure ability, the heat resistanceheat resistant shrinkage ability that expands is strong, has strong anti-ultraviolet radiation ability and temperature capacity, thereby has very long work-ing life, can satisfy the requirement of solar cell life-time service.
