Example Embodiment
[0047] Example 1:
[0048] The materials and specific gravity of UV-curable weather-resistant coating: 70wt% fluorocarbon resin, 10wt% trimethylolpropane triacrylate, 4wt% initiator Irgacure 184, 10wt% titanium dioxide (particle size 0.5μm), 1wt% dispersant DISPERBYK -111, 2wt% antioxidant 1010, 1.5wt% anti-hydrolysis agent Stabaxol-1, 1.5wt% hindered amine anti-aging agent.
[0049] First, add 50% fluorocarbon resin and all titanium dioxide to a vertical sand mill, use glass beads with a particle size of 1.5 mm as the sanding medium, and sand for 3 hours at a peripheral speed of 10 m / sec. Mother liquor. Then, the mother liquor and the remaining raw materials are mixed uniformly on a high-speed mixer to obtain a coating. The coating was applied to both sides of the PET substrate treated with plasma through the machine head, and the UV curing machine with a wavelength of 365nm was used for curing. The curing time was 10s to obtain a solar cell backsheet material with a thickness o...

[0051] Example 2:
[0052] The materials and specific gravity of UV-curable weathering coating: 60wt% epoxy resin, 15wt% 1,6-hexanediol diacrylate, 5wt% Jiangsu Huati 201 initiator, 15wt% silica (particle size 1μm), 1.5wt% dispersant DISPERBYK-112, 1.5wt% antioxidant 1076, 1wt% anti-hydrolysis agent Stabaxol-P100, 1wt% phenylpropazole anti-aging agent.
[0053] First, add 40% fluorocarbon resin and silica to a vertical sand mill, use glass beads with a particle size of 2 mm as the sanding medium, and sand for 4 hours at a peripheral speed of 12 m / sec. Mother liquor. Then, the mother liquor and the remaining raw materials are mixed uniformly on a high-speed mixer to obtain a coating. The coating was applied to both sides of the plasma-treated PBT substrate through the machine head, and the UV curing machine with a wavelength of 365nm was used for curing, and the curing time was 50s to obtain a solar battery backsheet material with a thickness of 300μm.

[0055] Example 3:
[0056] The materials and specific gravity of UV curable weather-resistant coating: 80wt% acrylic resin, 10wt% glycidyl methacrylate, 3wt% initiator Irgacure 1173, 5wt% alumina (particle size 2μm), 0.5wt% dispersant DISPERBYK-112 , 0.5wt% antioxidant 168, 0.5wt% anti-hydrolysis agent Stabaxol-P100, 0.5wt% benzophenone anti-aging agent.
[0057] First, 60% acrylic resin and alumina are added to a vertical sand mill, and glass beads with a particle size of 3 mm are used as the sanding medium, and the peripheral speed is 8 m / sec for 5 hours to prepare the mother liquor. Then, the mother liquor and the remaining raw materials are mixed uniformly on a high-speed mixer to obtain a coating. The coating was applied to one side of the corona-treated PNT substrate through the machine head, and a 365nm wavelength UV curing machine was used for curing. The curing time was 30s to obtain a solar battery backsheet material with a thickness of 200μm.
