Description
Technical field
The present invention relates to high molecular material function additive technical field more particularly to a kind of light for photovoltaic EVA adhesive film
Stabiliser compositions further relate to a kind of EVA adhesive film.
Background technique
EVA resin is ethylene-vinyl acetate copolymer, is a kind of thermoplastic macromolecule resin, linear molecular structure.
EVA resin poor heat resistance, Yi Yanshen and elasticity it is low, creep resistance is poor, be easy to produce and expand with heat and contract with cold, therefore, EVA resin be used as envelope
When filling the transparent EVA glue film of photovoltaic apparatus, need to be modified EVA resin.Generally, make EVA glue by adding crosslinking agent
Film crosslinks solidification while encapsulating cell piece, so that thermal expansion and contraction is eliminated, to improve heat resistance.Use EVA adhesive film
Solar battery sheet is encapsulated, and can be bonded together with upper and lower level protection materials, solar cell module is constituted.
The a part of modified EVA adhesive film as solar battery, although accounting for a seldom part of component overall cost,
But its quality decides the service life of solar battery, and therefore, it is highly important for improving EVA adhesive film anti-aging property.Mesh
Preceding all EVA adhesive films, which generally also need to add antioxidant, ultraviolet absorbing agent, light stabilizer and silane coupling agent etc., to be helped
Agent, sufficiently to ensure the weather resistance of EVA film adhesive for solar cell package.
Hindered phenol anti-oxidants or hindered phenol anti-oxidants and phosphorous can be selected in antioxidant for EVA photovoltaic film
The composition of esters of gallic acid antioxidant, hindered phenol anti-oxidants generally use antioxidant 1076, antioxidant 245 or antioxygen
Agent 3114 etc.；Phosphite antioxidant generally uses antioxidant 168 etc..The selection of antioxidant should give one's full attention to anti-
The compatibility of oxidant and EVA resin, processability and the synergistic with light stabilizer.
The technical requirements of light stabilizer for EVA photovoltaic film are higher, although the light fastness of EVA resin is relatively slightly good,
But due to the component for photovoltaic cell, by strong light radiation in the life cycle of entire solar cell module,
It therefore is still extremely important for the selection of light stabilizer.Currently, in the market for light used in solar energy EVA packaging adhesive film
Stabilizer is generally being used in compounding for benzophenone and benzotriazole ultraviolet absorbent and hindered amine light stabilizer.

Deng.
However, the ultraviolet absorbing agent now used, as benzophenone ultraviolet absorbent and benzotriazole are ultraviolet
For light absorbers except the function of absorbing ultraviolet light, there is can form chromophore and can be long-term because of hot oxygen with radical reaction
Effect causes to decompose, to generate xanthochromia to EVA adhesive film and influence high light transmittance, and then the problem of influence incident photon-to-electron conversion efficiency.
What is listed as follows is that benzophenone ultraviolet absorbent and benzotriazole ultraviolet absorbent formation add lustre to
The process of group.
For benzophenone ultraviolet absorbent:
For benzotriazole ultraviolet absorbent:
Meanwhile potential induction generating efficiency power attenuation (PID) problem of solar battery is increasingly by the weight of people
Depending on.Think according to the study, chief reason is still metal ion in component, mainly there is Na+、Ca2+、Ag+、Cu2+Deng caused by migration
's.To reduce PID, the modification of EVA adhesive film is focused primarily upon, polyolefin ionomers are added in EVA, slowed down under voltage driving
The migration velocity of metal ion；Hydrophobic auxiliary agent is added, reduces moisture content in EVA；The methods of or metal ion capturing agent is added,
But not yet notice the metal ion because existing in itself in the presence and its EVA resin of metal ion, for EVA glue
Xanthochromia caused by film aggravates, light transmittance decline, the problem of more deterioration so as to cause PID.This is because benzophenone is purple
The process that ultraviolet absorbers and benzotriazole ultraviolet absorbent form chromophore in the presence of hot oxygen light can be golden
Belong to ion and is catalyzed generation.
Therefore, although the light stabilizer system for being currently used for photovoltaic EVA adhesive film can satisfy weather resistance requirement, absolutely
Non- is ideal., it is still necessary to develop novel light stabilizer system.
