Abstract
The invention discloses a polyvinylidene fluoride photovoltaic back plate. The polyvinylidene fluoride photovoltaic back plate contains the following components by mass percent: 62-72% of polyvinylidene fluoride, 12-18% of polymethyl methacrylate, 4-8% of a core-shell mpact resistant modifier, 6-13% of inorganic titanium dioxide, 0.2-0.6% of an ultraviolet-resistant absorbent and 0.4-0.8% of an efficient stabilizer. The polyvinylidene fluoride photovoltaic back plate is manufactured by the following steps: (1) proportionally mixing the components and processing into master batches; and (2) directly extruding the master batches into the photovoltaic back plate with the thickness of larger than or equal to 180 micrometers, and molding at a time. The polyvinylidene fluoride photovoltaic back plate is favorable in surface tensile strength, does not have a weak area and is excellent in aging resistance and insulation effect.
