Description
Technical Field
The invention relates to the technical field of packaging adhesive films, relates to a packaging adhesive film and a preparation method and application thereof, and particularly relates to a low-corrosivity packaging adhesive film and a preparation method and application thereof.
Background
A photovoltaic module, i.e., a solar cell, is a device for directly converting solar energy into electric energy, and improving the power output of the photovoltaic module is a basic direction for packaging the solar photovoltaic module. The packaging adhesive film is mainly used for sealing and protecting the solar cell and plays a vital role in a photovoltaic module. At present, the conventional photovoltaic EVA (ethylene-vinyl acetate copolymer) and EVA/POE/EVA co-extrusion adhesive film on the market uses the conventional photovoltaic EVA, a vinyl acetate monomer is introduced into PE (polyethylene) in the EVA, but the vinyl acetate bond is weak and easy to break, and particularly under the high-temperature and high-humidity environment, the EVA can break to generate acetate, and generates acetic acid when meeting water to release acid gas. At present, in order to ensure the transparency and the processability of the adhesive film, the EVA with the VA content of 28% is usually selected, and the EVA with the VA content of 28% is easy to release more acetic acid, and the released acetic acid can corrode a battery piece, a welding strip and a bus bar, so that the appearance and the power generation efficiency of a component are finally influenced.
Since no acidic monomer is introduced in the synthesis of POE (polyolefin elastomer) and no polarity exists, no acidic gas is released. Therefore, POE is generally used in the market to replace EVA to improve the reliability of the component. However, POE is nonpolar, the crosslinking agent and the coupling agent added in the adhesive film have very high polarity, so that the POE is difficult to absorb the auxiliary agent, and after the adhesive film is prepared, the auxiliary agent is easy to separate out on the surface of the adhesive film, so that the adhesive film has the problems of slipping and deviation in the using process, and the automatic production of the assembly is influenced; moreover, the POE has low activity and is difficult to crosslink, so that the crosslinking time is long, and the productivity of the assembly is also influenced.
In order to improve POE's the problem of skidding, provided a structure of EVA/POE/EVA three-layer coextrusion, put the POE layer in the centre, just so avoided POE auxiliary agent to appear the problem of skidding, nevertheless, because EVA's existence, still have the problem that a large amount of acetic acid were appeared.
CN102766412A discloses a novel photovoltaic packaging adhesive film, a preparation method and a use method thereof, wherein the adhesive film is a metallocene polyethylene film, and the metallocene polyethylene film is composed of the following raw materials, by mass, 100 parts of metallocene polyethylene resin, 0.8-8.4 parts of a cross-linking agent, 0.01-4 parts of a tackifier, 0.05-5 parts of an antioxidant and 0.01-0.5 part of a light stabilizer. The preparation method comprises the following steps: (1) uniformly mixing a light stabilizer and an antioxidant; (2) uniformly mixing a crosslinking curing agent with the mPE granules; and (3) adding the rest materials and the mixture obtained in the step (1) into the step (2), uniformly mixing, and then blending and extruding to obtain the adhesive film. Compared with EVA, metallocene polyethylene (mPE) designed by metallocene catalyst catalysis has stronger humidity and heat resistance, low metal corrosion, higher volume resistivity, low leakage rate, low moisture permeability and the like, and can be used as a novel solar cell packaging adhesive film. However, the haze, the light transmittance and the PID resistance of the packaging adhesive film of the present invention are all to be further improved.
CN108586903A discloses a solar photovoltaic cell packaging material and a preparation method thereof, belonging to the technical field of packaging materials. The laminated double hydroxide is prepared from magnesium nitrate, aluminum nitrate and zinc nitrate, and methyl methacrylate, europium acrylate and the like are inserted into the interlayer spacing of the laminated double hydroxide by an intercalation method, so that the interlayer spacing of the laminated double hydroxide is increased, the laminated double hydroxide has a larger reaction space, the absorption effect on acetic acid molecules generated by ethylene-vinyl acetate degradation is enhanced, the corrosion performance is reduced, the inhibition effect is achieved, the thermal stability is obviously improved, and meanwhile, the ultraviolet aging resistance of a photovoltaic cell packaging adhesive film is improved by copolymerizing methyl methacrylate and europium acrylate with ethylene-vinyl acetate and adding europium element; the solar photovoltaic cell packaging material prepared by the invention is convenient to operate, excellent in product performance and environment-friendly, reduces the consumption of petroleum resources and energy sources in solar cell packaging, has wide application prospect, and is an innovative green packaging material. However, the preparation method of the packaging adhesive film is complex, and the packaging adhesive film is high in cost and difficult to realize mass production.

TABLE 1
As can be seen from the data in Table 1, the low-corrosivity packaging adhesive film prepared by the invention has excellent transmittance and haze, has low corrosivity, reduces the problem of acetic acid precipitation, and ensures the long-term reliability of the assembly.
Example 6 replacement of the nucleating agent with NAR-6 (sodium benzoate) will not function as a nucleating agent and will not improve the light transmittance of the EVA adhesive film.
The EVA content of comparative example 1 is 28%, which increases the VA content, corrodes the welding strip of the cell and affects the generating efficiency of the assembly.
The EVA content of the comparative example 2 is 5%, so that the transmittance of the adhesive film is reduced, the haze is increased, the light ray passing through the adhesive film is influenced, and the initial power generation power of the assembly is reduced.
Comparative example 3, which contains no alkaline salts, increases free acetic acid, which affects the PID resistance of the assembly and corrosion of the cell strip.
Comparative example 4 too much alkaline salt was used to deteriorate the appearance of the adhesive film, because the salt was not compatible with the EVA resin, and the salt content was increased, resulting in many crystal spots of the salt in the adhesive film.
Comparative example 5, which contains no nucleating agent, causes poor haze and light transmittance of the adhesive film, and affects the power generation efficiency of the module.
Comparative example 6 too much nucleating agent will deteriorate the compatibility of the formulated system, and the amount of nucleating agent out of the range will not improve the transparency, but reduce the transmittance of the film due to the poor compatibility.
Comparative example 7 does not contain alkaline salt and nucleating agent at the same time, so that the free acetic acid of the adhesive film is increased, and the transmittance is reduced.
Compared with the prior art, the Ethylene Vinyl Acetate (EVA) is replaced by the polyolefin elastomer (POE) in the comparative example 8, acetic acid is not precipitated from the adhesive film, but the auxiliary agent is difficult to absorb, the crosslinking degree of the adhesive film cannot meet the use requirement under the formula system, and the weather resistance and the Proportion Integration Differentiation (PID) resistance of the assembly are poor.
In the comparative example 9, the alkaline salt is replaced by potassium hydroxide, and the EVA resin is degraded due to too high alkalinity, so that the adhesive force performance of the adhesive film is seriously reduced.
