Description
Technical field
The invention belongs to photovoltaic material field, is related to a kind of EVA adhesive film and preparation method thereof, more particularly to a kind of anti-PID
Type photovoltaic EVA packaging adhesive films and preparation method thereof.
Background technology
Since 2013, with domestic and international up-front investment photovoltaic plant generating electricity by way of merging two or more grid systems successively and run a period of time
Afterwards, the quality problems of home and abroad station occur on a large scale.Many power stations have broken into snail line, potential induction attenuation
The quality problem of (Potential Induced Degradation, PID) etc..Some domestic power stations are due to having used poor quality
EVA (Ethylene Vinyl Acetate, ethene-vinyl acetate copolymer) glued membrane, power station is caused to run 1 year or so just
It is found that up to 60% decay.
Sodium ion in the hydrolysis and glass of PID formation mechenism and EVA has very close relationship.When aqueous vapor passes through edge sealing
Silica gel or after backboard enters component internal, ester bond in EVA meets water decomposition, produces the acetic acid that can be moved freely.Acetic acid and
After the alkali reaction that glass surface separates out, the sodium ion that can be moved freely is produced.These sodium ions are in the presence of extra electric field
Leakage current is formed to the movement of cell piece surface.In the presence of leakage current, the carrier of positively charged passes through glass, passes through frame
Flow to ground so that in cell piece surface sediment, the surface aggregation that attraction photocurrent carrier (hole) flows to N-type silicon rises negative electrical charge
Come, rather than positive pole (P poles) is flowed to as under normal condition.Declined so as to the power output because of caused by Surface Polarization occur
The PID effects subtracted.
At present from encapsulating material come to solve PID Main Basiss be the hydrolysis and increase EVA exhausted in itself that reduce EVA material
Edge resistance.Thus VA (Vinyl Acetate, vinyl acetate) content in more EVA adhesive films using reduction, or suitably change formula,
Increase specific insulation, so as to hinder the migration of sodium ion, delay PID to decay.
CN105820764A discloses a kind of photovoltaic encapsulation EVA compound cutans with anti-PID performances, by from VA
Content is 20%~26% EVA resin, coordinates other additives so that there is glued membrane anti-PID to act on.VA contents are reduced, Gu
PID decay can so be alleviated, but material polarity is reduced, peel strength variation, crosslinking degree reduces, so as to add
The application risk of EVA adhesive film.
CN103756578A discloses the EVA packaging adhesive films that a kind of fluorine compounds are modified, have good hydrolytic resistance with
And insulating properties, reach anti-PID purpose, but by increasing its insulating properties, that is, increase the specific insulation of EVA adhesive film, though
Control PID is so can be very good in a short time, but there is the hidden danger of failure on long terms.Because EVA adhesive film is using process
In aging and degraded can occur, specific insulation can reduce over time, so as to cause anti-PID effect failure.
Therefore, in the art, it is expected to obtain a kind of anti-PID that can be permanently effective EVA adhesive film.
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 EVA adhesive film and preparation method thereof, it is particularly
A kind of anti-PID types photovoltaic EVA packaging adhesive films and preparation method thereof are provided.EVA adhesive film of the present invention has permanently effective resist
PID effects, and its reliability and stability is good.
To use following technical scheme up to this purpose, the present invention：
On the one hand, the present invention provides a kind of EVA adhesive film, and the preparing raw material of the EVA adhesive film includes EVA resin and with EVA
The quality meter of resin, the following component of percentage composition：
In the present invention, by using ion capturing agent, and EVA adhesive film composition and its content are selected so that EVA
Glued membrane overcomes that material polarity reduces, peel strength is deteriorated, crosslinking degree and cross-linked speed are relatively low, is easy to aging and degraded, body
The shortcomings that product resistivity reduces, the anti-PID performances of EVA adhesive film can be ensured for a long time.
In the present invention, the weight/mass percentage composition of the EVA resin VA (vinyl acetate) be 28~33%, such as 28%,
29%th, 30%, 31%, 32% or 33%；The melting means of the EVA resin is 22~28g/10min, such as 22g/10min, 23g/
10min, 24g/10min, 25g/10min, 26g/10min, 27g/10min or 28g/10min.In the present invention without specially dropping
Low VA contents, 28~33% VA contents may be selected, avoid because reducing VA contents so that material polarity reduces, peel strength
It is deteriorated, the increase of caused EVA adhesive film application risk the defects of crosslinking degree and relatively low speed, it is therefore prevented that VA contents wave zone comes
Quality unstability.
Preferably, specific insulation >=1.0 × 10 of the EVA resin15Ω .cm, such as 1.0 × 1015Ω.cm、3.0
×1015Ω.cm、5.0×1015Ω.cm、8.0×1015Ω .cm or 1.0 × 1016Ω .cm etc.

The degree of cross linking can be relatively low, due mechanical performance can not be obtained so as to product, if assistant crosslinking agent is excessive, do not participate in cross-linking reaction
Assistant crosslinking agent molecule remain in EVA, EVA cross-linked speed can be influenceed, make EVA be difficult to smoothly produce.
Preferably, the assistant crosslinking agent is Triallyl isocyanurate and/or trimethylol propane trimethyl acrylic acid
Ester.
In the present invention, the dosage of the light stabilizer can be EVA resin quality 0.2~0.5%, such as 0.2%,
