Repairing tape for photovoltaic module backboard, and bonding process and application thereof

The invention discloses a repairing tape for a photovoltaic module backboard, and a bonding process and application thereof. The repairing tape for the photovoltaic module backboard comprises a substrate layer, a functional adhesive layer and a release material layer which are sequentially arranged from top to bottom, wherein the substrate layer and the functional adhesive layer are of an integralwhole-surface structure, the release material layer is a two-section type release material layer, and each section of the two-section type release material layer is provided with a tear tape. The repairing tape is used for repairing a solar battery backboard, and has high insulation, low water vapor permeation rate and high weather resistance; the bonding process is simple, the bonding efficiencyis high, and the repairing tape is especially suitable for on-site repairing of the photovoltaic module backboard. 本发明公开了一种光伏组件背板用修补胶带及其贴合工艺及应用。本发明的光伏组件背板用修补胶带，包括由上至下依次设置的基材层、功能胶层、离型材料层，所述基材层、功能胶层为一体式整面结构，所述离型材料层为两段式离型材料层，所述两
