Abstract

The invention discloses a preparation process of a photovoltaic film with strong weather resistance based on POE materials, which belongs to the field of photovoltaic film technology clamping, and specifically includes the following steps: S1, prefabrication of raw materials; S2, weighing of raw materials; S3, compound extrusion out; S4, made by hot pressing. In the present invention, the air permeability and water resistance of the inner film and the bonding bottom layer are modified and enhanced by filling the modified filler silica and iron powder particles in the micropores, and at the same time, the iron powder particles can enhance the impact resistance of the inner film. It can improve the overall strength of the photovoltaic module after being covered by the adhesive film, realize the treatment and modification of the water barrier strength through the POE material of the core layer, and realize the multi-layer substrate by laminating the multi-layer adhesive film and the bypass air pump during preparation. The control and adjustment of the thickness of the blown film can meet the precise control of the thickness of the photovoltaic film, and improve the overall weather resistance of the photovoltaic film, avoid the corrosion of the photovoltaic module panel caused by water seepage at the base layer, and prolong the overall durability of the photovoltaic module after assembly. .

Description

technical field [0001] The invention belongs to the technical field of photovoltaic adhesive films, and in particular relates to a preparation process of a photovoltaic adhesive film with strong weather resistance based on POE materials. Background technique [0002] A typical photovoltaic module consists of solar cells, back sheets, photovoltaic glass, junction boxes, frames, packaging materials, etc. The encapsulation film material is located between the photovoltaic glass and the solar cell, which can bond the solar cell, the copper tin solder tape, the back sheet and the photovoltaic glass together, and is a key component of the photovoltaic module. "The ethylene-vinyl acetate copolymer (EVA) encapsulation film in photovoltaic cells is a thermosetting and adhesive film, because EVA film has special advantages in adhesion, durability, optical properties, etc., Therefore, it is widely used in photovoltaic modules and various optical products.
