Abstract

The invention relates to a solar photovoltaic backing composite and a preparation method thereof and belongs to the technical field of the composites. The solar photovoltaic backing composite is prepared from the following raw materials in parts by mass: 10-25 parts of carbon nanotubes, 10-16 parts of PBT, 2-6 parts of maleic anhydride grafted ethylene propylene diene monomer, 5-10 parts of high-density polyethylene, 2-6 parts of ABS, 2-5 parts of glyceryl tristearate, 1-3 parts of silicone powder, 2-9 parts of citric acid, 2-4 parts of tri[2,4-di-tert-butylphenyl] phosphite, 2-5 parts of silicon carbide fibers and 1-3 parts of gamma-methylacryloxypropyltrimethoxy silane. The solar photovoltaic backing composite has excellent mechanical properties and weather fastness; and the obtained composite also has excellent water vapor barrier property and is capable of effectively protecting a solar cell.

Description

[0001] technical field [0002] The invention belongs to the technical field of composite materials, and in particular relates to a solar photovoltaic backplane composite material and a preparation method thereof. [0003] Background technique [0004] 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 polyester film with good insulation properties, and the inner layer PVDF and EVA have good bonding properties . At present, the domestic demand for solar cell back film continues to increase, and the market prospect of solar cell back film is very broad. [0005] However, although the existing solar cell back film has a multi-layer structure, its protective effect on the solar cell still needs to ...
