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.
