Abstract

The invention discloses a POE (Polyolefin Elastomer) material-based high-weather-resistance photovoltaic adhesive film preparation process, and belongs to the field of photovoltaic adhesive film technology clamping. The POE material-based high-weather-resistance photovoltaic adhesive film preparation process specifically comprises the following steps of S1, prefabricating raw materials; S2, weighing the raw materials; S3, mixing and extruding; and S4, performing thermocompression bonding. According to the POE material-based high-weather-resistance photovoltaic adhesive film preparation process provided by invention, the air permeability and the water resistance of an inner film and a bonding bottom layer are modified and enhanced by filling micropores with modified filler silicon dioxide and iron powder particles, and meanwhile, the iron powder particles can enhance the impact resistance of the inner film, so that the overall strength of a photovoltaic module after being covered with an adhesive film is improved; and the waterproof strength is treated and modified through a POE material of a core layer, and the film blowing thickness of multiple layers of substrates is controlled and adjusted through multiple layers of laminated adhesive films and a bypass air pump during preparation, so that the thickness of the photovoltaic adhesive film can be accurately controlled, the overall weather resistance of the photovoltaic adhesive film is improved, corrosion of a photovoltaic module panel caused by water seepage of a base layer surface is avoided, and the overall durable life of the assembled photovoltaic module is prolonged.
