Abstract

The invention discloses a photovoltaic cell module packaging adhesive film, and a preparation method and application thereof. The photovoltaic cell module packaging adhesive film comprises a polyolefin adhesive film layer, and the polyolefin adhesive film layer comprises polyolefin resin, a cross-linking agent, an assistant cross-linking agent, a UV stabilizer, a UV absorbent, a heat stabilizer and a compatilizer. According to the invention, after the compatibilizer is added into a POE layer, the compatibilizer has polarity, so that the compatibilizer can be well compatible with the auxiliary agent, the auxiliary agent is not easy to separate out and is not easy to slip when being combined with a battery piece, the defects of the POE in the application of the solar battery are relieved, and meanwhile, the compatibilizer still has the advantages of the POE in the application of the solar battery. In addition, due to the addition of the compatilizer, the POE layer and the organic silicon layer can be effectively combined, and the invention further discloses a photovoltaic cell module composite packaging adhesive film comprising a polyolefin adhesive film layer and a silicon rubber film layer located on the surface of the polyolefin adhesive film layer.

Description

Technical field [0001] The present invention relates to the field of packaging materials for photovoltaic cell modules, and more particularly to a photovoltaic cell module package film and a preparation method thereof. Background technique [0002] The polyolefin elastomer (POE) is a copolymer of ethylene and butene or octene, and its molecular chain is a saturated olefin structure, the molecular chain structure is stable, non-polar, not easy to crystallize. Therefore, the polyolefin elastomer has excellent water vapor barrier ability, ion barrier ability, and high light transmittance, and the aging process does not produce acidic substances, which has excellent anti-aging properties; and high material volume resistivity, excellent anti-PID performance, An application of a wide range of photovoltaic cell modules to encapsulate film materials. [0003] In addition to the polyolefin elastomer resin matrix, the POE encapsulating film component also contains a crosslinking agent, a b...
