Abstract

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.

Description

technical field [0001] The invention belongs to the field of repairing tapes, and in particular relates to a repairing tape for a backplane of a photovoltaic module, a bonding process and application thereof. Background technique [0002] The solar module backsheet needs to have reliable insulation and water resistance to ensure the normal operation of the module. At present, there are two main types of module damage. One is that during the transportation and installation of the module, some of the backplane of the module will be damaged and scratched, resulting in safety failure and functional failure of the module during operation; the other is that the module is used outdoors. After a period of time, the backplane will gradually age and crack, failing to meet the safety requirements of the components during operation. [0003] The damaged backplane can only be replaced by components. If it is replaced in large quantities, the cost will be extremely high, and it will be d...
