Description
Technical Field
The invention relates to the field of packaging materials for solar photovoltaic cell modules, in particular to a polyolefin photovoltaic packaging adhesive film and a preparation method thereof.
Background
With the increasing attention on clean energy and the continuous reduction of solar photovoltaic power generation cost in the world, the installed capacity of a photovoltaic power generation market is rapidly increased, and the market space is huge. In the photovoltaic module, the photovoltaic packaging adhesive film is used for bonding the photovoltaic glass, the cell piece and the back plate together through a laminating process; as one of the key materials in the photovoltaic module, the requirements for the packaging adhesive film are high light transmittance, high adhesive strength, ultraviolet and high and low temperature resistance, low water vapor transmission rate, high resistivity, and the like.
The current commonly used packaging adhesive film material is mainly composed of an ethylene-vinyl acetate copolymer (EVA) as a matrix and a small amount of additives such as a crosslinking agent, an auxiliary crosslinking agent, a UV stabilizer, a heat stabilizer and the like. However, the EVA material has high water vapor transmission rate, and under the action of light, heat and oxygen, lactone structures such as unsaturated double bonds, acetic acid, a small amount of acetaldehyde and ketone groups can be generated, which leads to the decrease of the material light transmittance, yellowing and poor PID resistance.
The polyolefin elastomer (POE) is a copolymer of ethylene and butylene or octene, and the molecular chain of the polyolefin elastomer is of a saturated olefin structure, has a stable molecular chain structure, is nonpolar and is not easy to crystallize, so that the polyolefin elastomer has excellent water vapor barrier capability, ion barrier capability and high light transmittance, does not generate acidic substances in the aging process, and has excellent aging resistance; and the volume resistivity of the material is high, and the PID resistance is excellent. In the aspect of photovoltaic packaging adhesive films, the film is an ideal substitute for EVA materials.
However, since the POE is a non-polar material, the bonding strength between the POE and the photovoltaic glass and the back plate is low, the peeling strength attenuation is large, the requirement of the photovoltaic module on the outdoor service life of twenty-three years cannot be met, and the key for the widespread application of the POE photovoltaic adhesive film is to improve the bonding strength of the POE photovoltaic adhesive film and reduce the product cost; patent CN103289582 provides a cross-linked POE solar photovoltaic module packaging adhesive film, which is prepared by obtaining a graft modification material by POE graft silane coupling agent, mixing with cross-linking agent, cross-linking auxiliary agent, antioxidant and other auxiliary agents, and extruding to form a film; patent CN105330928 provides a polyolefin photovoltaic film with high peel strength retention rate, which is prepared by uniformly mixing POE grafted maleic anhydride, glycidyl methacrylate or gamma-methacryloxypropyl trimethoxy silane to obtain POE grafted master batch, and then casting the grafted master batch with POE, initiator, crosslinking accelerator and other auxiliaries to form a film through a casting machine, thereby obtaining the polyolefin photovoltaic film with high bonding strength.
Although the method can improve the peeling strength of the POE adhesive film, the problem of higher product cost still exists, and the wide application of the product is limited. Therefore, a polyolefin photovoltaic packaging adhesive film and a preparation method thereof are needed.

Detection examples
The detection method of the crosslinking degree comprises the following steps: laminating, crosslinking and curing a polyolefin photovoltaic packaging adhesive film on a vacuum laminating machine, taking about 0.5g of the laminated adhesive film, cutting into small particles, putting the small particles into a stainless steel wire mesh bag which is cleaned and dried, and then putting the stainless steel wire mesh bag into a dimethylbenzene solvent to extract for 5 hours at 140 ℃; taking out the sample after extraction is finished, and drying the sample in a vacuum drying oven at 140 ℃ to constant weight; and calculating the crosslinking degree of the adhesive film according to the weight of the dried sample (laminating process: air extraction for 6min, temperature of 145-150 ℃ and time of 10-15 min).
The detection method of the light transmittance of the adhesive film comprises the following steps: testing the light transmittance of the laminated adhesive film according to the method of GB/T2410-2008; the wavelength range is 290 nm-1100 nm (laminating process: air exhaust for 6min, temperature 145-150 ℃, time 10-15 min).
Detection method of 180 ° peel strength: testing the peeling strength of the adhesive film, the glass and the back plate after lamination according to the method of GB/T2790-1995; the stretching speed is 100 mm/min; sample structure: glass/adhesive film/back plate (laminating process: air extraction for 6min, temperature 145-150 ℃, time 10-15 min).
The detection method of the humidity and heat resistance of the adhesive film comprises the following steps: testing the humidity and heat resistance of the laminated adhesive film according to the method of IEC 61215-2: 2016; the stretching speed is 100mm/min, the damp-heat experiment temperature is 85 ℃, the relative humidity is 85 percent, and the time is 2000 h; sample structure: glass/adhesive film/back plate (laminating process: air extraction for 6min, temperature 145-150 ℃, time 10-15 min).

As can be seen from Table 1, the polyolefin photovoltaic packaging adhesive film prepared by the method has good light transmittance and water vapor barrier property, and meanwhile, the adhesive film has high peeling strength with glass and a back plate and excellent moisture and heat resistance, and can meet the packaging and using requirements of a solar photovoltaic cell module.
Resin matrixes of an upper layer polyolefin adhesive film, a core layer polyolefin adhesive film and a lower layer polyolefin adhesive film in the polyolefin photovoltaic packaging adhesive film are POE (polyolefin elastomer), compatibility among the film layers is good, and the problem of interlayer separation cannot occur in the use process of a photovoltaic module; in addition, the upper polyolefin adhesive film and the lower polyolefin adhesive film which are in contact with the photovoltaic module glass, the back plate and the cell piece contain the tackifier, and the core layer polyolefin adhesive film does not contain the tackifier, so that the use of a UV absorbent, a UV stabilizer and a heat stabilizer in the core layer polyolefin adhesive film is even reduced, the high bonding strength of the polyolefin photovoltaic packaging adhesive film and the glass, the back plate and the cell piece can be ensured, and the production cost of the product can be reduced; meanwhile, redundant auxiliary agents in the upper polyolefin adhesive film and the lower polyolefin adhesive film can be absorbed through the core layer polyolefin adhesive film, so that the problems of slippage, sheet merging or air bubbles and the like of a battery sheet caused by the separation of the auxiliary agents in the laminating process of the single-layer POE adhesive film can be effectively solved, and the laminating efficiency and the yield of the assembly are remarkably improved.
