Preparation method of high-stability and high-transparency composite photovoltaic adhesive film

The invention discloses a preparation method of a high-stability and high-transparency composite photovoltaic adhesive film, and relates to a preparation method of a photovoltaic adhesive film, in the method, a photovoltaic adhesive film composition is prepared from the following raw materials in parts by mass: 70 to 90 parts of POE (Polyolefin Elastomer), 0 to 30 parts of POE (Polyolefin Elastomer) grafted polar monomer, 0 to 10 parts of annular block copolymer, 0 to 2 parts of silane coupling agent, 0.5 to 3 parts of thermal initiator and 0.5 to 3 parts of antioxidant. And 0.1 to 2 parts of a photoinitiator. The preparation method mainly solves the problems of transparency problem, assistant migration and precipitation, non-uniform casting thickness, poor cohesiveness, film crystal point and black point existing in the conventional photovoltaic adhesive film, and belongs to the field of photovoltaic adhesive film manufacturing, the transparency of the photovoltaic film is improved by adding the annular bloc
