Description
Technical Field
The invention belongs to the technical field of packaging adhesive films, and particularly relates to an anti-slip POE adhesive film based on cyclodextrin loading auxiliary agents and a preparation method thereof.
Background
Solar cell modules (also called solar panels, photovoltaic modules) are the core part of and the most important part of a solar power generation system. The solar energy is converted into electric energy, and the electric energy is sent to a storage battery for storage or for pushing a load to work. The photovoltaic module equipment is used as core equipment of a photovoltaic power station, and can be mainly divided into a single glass module and a double glass module from the packaging angle, and along with the continuous development of the photovoltaic power generation industry and the continuous improvement of the photovoltaic technology, the double-sided battery is rapidly developed. In the current market, double-sided battery assemblies mostly adopt double-glass packaging, and a few use transparent backboard packaging. The packaging adhesive film for the double-glass assembly at present mainly comprises Ethylene-vinyl acetate copolymer (EVA) and Ethylene-octene copolymer (Polyolefin Elastomer, POE).
PID (Potential Induced Degradation, abbreviated as PID) is known collectively as potential induced decay, and the PID effect causes a significant amount of charge to accumulate on the cell surface, disabling passivation of the cell surface, resulting in a sudden drop in power of the cell assembly. With the recent large-scale application of photovoltaic systems, the system voltage is higher and higher due to the innovation of photovoltaic industry technology, and meanwhile, the aluminum alloy frames of the components are required to be grounded due to the requirement of lightning protection engineering, so that high direct current voltage is formed between the battery pieces and the aluminum frames. The packaging adhesive film EVA material of the component cannot achieve 100% insulation, in the use process, water vapor permeates into the component through silica gel, a back plate and the like, the EVA material is decomposed after encountering water, so that acetic acid capable of freely moving is generated, sodium ions capable of freely moving can be formed after the acetic acid capable of freely moving reacts with alkali separated from the surface of glass, the sodium ions move to the surface of a battery under the action of an external electric field, and an antireflection layer gathered on the surface of the battery is formed, so that PID phenomenon is caused. The water enters the assembly, EVA is decomposed to generate acetic acid when meeting water, the acetic acid reacts with alkali to generate sodium ions, the sodium ions are enriched on the surface of the battery, and the four steps are the whole process formed from the PID view, and the process is also a PID effect cause widely accepted in the photovoltaic industry at present.
The POE packaging adhesive film is developed by taking metallocene as a catalyst, and is a novel polyolefin thermoplastic elastomer with narrow relative molecular mass distribution, narrow comonomer distribution and controllable structure. Because of the nonpolar characteristic, POE has excellent water vapor blocking capability and ion blocking capability, and the water vapor transmittance is only about 1/8 of EVA; because the molecular chain structure is stable, acidic substances are not generated in the aging process, and the material has excellent aging resistance and is a preferred material for the packaging adhesive film of the photovoltaic module with high efficiency and high reliability. Although the performance of the POE adhesive film has better water vapor blocking capacity and better ageing resistance compared with the traditional EVA adhesive film, the low polarity of the POE also brings some problems, more or less auxiliary agents which are indispensable in the adhesive film preparation process at the present stage have certain polarity, the auxiliary agents are difficult to directly absorb POE particles, and in the subsequent adhesive film preparation process, the POE particles are easy to separate out from the adhesive film, so that two more serious results can be caused: the auxiliary agent does not fully participate in the reaction, the crosslinking degree of the adhesive film is low, and the performance of the prepared photovoltaic module is affected; the other is that the precipitated auxiliary agent can remain on the surface of the adhesive film, so that the adhesive film can generate slipping phenomenon in the preparation process of the component, and the preparation process difficulty of the component is increased.
