Description

technical field [0001] The invention relates to the technical field of photovoltaic materials, in particular to a method for preparing an adhesive for photovoltaic backplanes. Background technique [0002] Adhesive refers to a natural or synthetic, organic or inorganic substance that can connect two or more parts or materials together through the adhesion and cohesion of the interface, also known as bonding. Agent, customarily referred to as glue. In short, an adhesive is a substance that can bind adherends together through bonding. "Adhesive" is a general standard term that also includes other glues, putties, mucilages, plasters, etc. [0003] The solar backsheet is located on the back of the solar panel, which protects and supports the battery sheet, and has reliable insulation, water resistance, and aging resistance. Generally has a three-layer structure (PVDF / PET / PVDF), the outer protective layer PVDF has good environmental erosion resistance, the middle layer is PET ...
