摘要
Abstract
In this study,hydrogenated hydrocarbon resin(H-HCR)was melt blended with POE using dicumyl peroxide(DCP)as a crosslinking agent and hexadecyl 3,5-di-tert-butyl-4-hydroxy-benzoate(UV2908)as a UV absorbers for fab-ricating a UV cut-off PV encapsulation film with high volume resistance.The transmittance of the blending films in the UV region(250～380 nm)was significantly reduced with an increase in the H-HCR content,and its high transmittance in the visible/near-infrared region of 380～1 100 nm was maintained.Meanwhile,UV2908 exhibited excellent UV cut-off performance in the range of 250～292 nm.The two components could generate a synergistic effect to prevent UV from entering PV modules,resulting in the formation of a PV encapsulation film with a high UV cut-off function.Mean-while,the mechanical properties and volume resistivity of the blending films were significantly enhanced,and their vol-ume resistivity reached the highest value at an H-HCR content of 15 wt%.When the POE/H-HCR/DCP/UV2908 mass ratio was 85/15/1.5/0.2,the average transmittance and UV cut-off wavelength of the blending films in the visible/near-infrared region are 91.6%and 284 nm,respectively.Their tensile strength,elongation at break and volume resis-tivity reached 20.1 MPa,904%and 5.9×1015 Ω·cm,respectively.The blending materials demonstrated not only good volume resistivity and mechanical properties but also excellent UV cut-off performance.关键词
