Embodiment Construction

[0068] The preferred embodiments of the present invention will be described in detail below in conjunction with specific examples.

[0069] 1, Preparation of insulating tape

[0070] The hydroxyfluorocarbon resin is dissolved in butyl acetate (or commonly used ethyl acetate, acetone, toluene, xylene, N,N-dimethylformamide, etc.) solvent at 50% by mass, and hydrogenated epoxy Resin, carbon black filler, dispersant BYK9076, after dispersion and sanding treatment. Then add isocyanate curing agent, dibutyltin dilaurate curing accelerator, and stir evenly, and evenly coat a 5 μm thick coating on the polyimide film (PI). Heat to evaporate to dryness, then roll up for later use.

[0071] Epoxy resin, thermoplastic resin and / or synthetic rubber are dissolved in butanone (or commonly used acetone, toluene) by mass percentage as 20% in butanone (or commonly used acetone, toluene, Xylene, N,N-dimethylformamide, etc.) solvent, and then add flame retardant to the resin solution, after...

Abstract

The invention relates to a photovoltaic module bus bar insulated rubber tape, a bus bar containing the insulated rubber tape and a photovoltaic module. The insulated rubber tape comprises an insulatedbase material layer, a coating formed on one side of the insulated base material layer, and an adhesive layer formed on the other side of the insulated base material layer, wherein a raw material formula of the coating comprises a fluorocarbon resin containing hydroxyl or amino, a filler, an assistant and a first curing agent; and a raw material formula of the adhesive layer comprises an epoxy resin, a thermoplastic resin and / or synthetic rubber, a second curing agent and a flame retardant. The coating and the base material have excellent adherence, the scratching force is still kept at 0-1 level even if after high temperature and high humidity, and the coating has outstanding ultraviolet barrier property. The adhesive layer has excellent adherence to the base material layer, and also hasexcellent adhesiveness to metals. The insulated rubber tape has ultraviolet resistance, heat shock resistance, cold and hot impact resistance, thermal-humidity resistance and environmental aging resistance. The insulated rubber tape is hot-pressed on a metal plate or a metal bus bar and can be applied to insulating the photovoltaic module bus bar.

Description

technical field [0001] The invention belongs to the field of insulating tapes, and relates to an insulating tape for a bus bar of a photovoltaic module, a bus bar containing the insulating tape, and a photovoltaic module. Background technique [0002] Photovoltaic module bus bars are used to connect the cells connected in series to each other. The current process is to manually weld and connect the bus bars and the solder strips drawn from the battery, and then use insulating isolation film / insulation strips to separate, insulate and fix the bus bars. [0003] In the past, the connection between the bus bar of the photovoltaic module and the battery strip was manually welded, and the efficiency was relatively low; the thick insulating film was used to isolate the bus bar and the bus bar, which made the local area bulge and affected the appearance. Flatness: The surface layer of the existing bus bar is exposed in the encapsulation film (such as transparent polyolefin materia...
