Abstract

The invention relates to a solar double-glass photovoltaic module laminating and edge sealing adhesive tape. The adhesive tape comprises a substrate layer and a pressure-sensitive adhesive layer located on the substrate layer, and a pressure-sensitive adhesive is prepared from, by weight, 70-90 parts of soft monomers, 1-20 parts of hard monomers, 0.5-5 parts of a polymerization initiator, 1-2 parts of a cross-linking agent, 0.1-0.5 part of an antioxidant and 1-5 parts of a baking pore-forming agent. The edge sealing adhesive tape has the good adhering fitness to a glass substrate, uniform through holes can be formed in a tape body through the volatilization action of water vapor when baking is conducted due to presence of the baking pore-forming agent, therefore, an air ventilation function is achieved, and the problems generated when holes are formed in common high-temperature adhesive tape through a physical method are solved; after the edge sealing adhesive tape is used, edge trimming is not needed, the adhesive tape is directly torn off after laminating is finished, and meanwhile overflowed high-molecular polymers are taken away, so that the labor intensity of workers is reduced, the cost of existing edge sealing adhesive tape is reduced, the appearance problems such as burrs are solved, and the uniform edge thickness requirement of a double-glass module is met.

Description

technical field [0001] The invention relates to an edge-sealing tape, in particular to a solar double-glass photovoltaic module lamination edge-sealing tape and a preparation method thereof, belonging to the technical field of solar double-glass photovoltaic modules. Background technique [0002] In the production process of photovoltaic cell modules, the edge protection is generally realized by aluminum alloy frames, and the sealing is done by silica gel or adhesive tape. With prominent performance advantages, it has gradually become a mainstream product in the photovoltaic market. Compared with traditional modules, ultra-thin double-glass modules use glass backplanes, which have the advantages of light weight, long life, reduced potential-induced degradation (PID) cracks, no snail marks, and high fire protection rating. In the current lamination process of solar double-glass photovoltaic modules, crystalline silicon cells are stacked in the module. After the lamination op...
