Abstract

The invention relates to a solar double-glass photovoltaic module lamination edge sealing tape, which comprises a base material layer and a pressure-sensitive adhesive layer located thereon, and the pressure-sensitive adhesive comprises the following components in parts by weight: 70-90 parts of soft monomer , 1-20 parts of hard monomer, 0.5-5 parts of polymerization initiator, 1-2 parts of crosslinking agent, 0.1-0.5 parts of antioxidant, 1-5 parts of baking porogen. The edge-sealing adhesive tape of the present invention has good adhesiveness and compliance to the glass substrate, and the presence of the baking porogen makes it possible to use the volatilization of water vapor to produce uniform through holes on the colloid during baking, thereby realizing the breathable function and solving the problem of The problems caused by the physical method of ordinary high-temperature tape drilling; after using this edge-sealing tape, there is no need to cut the edge, and the tape is torn off directly after lamination, and the overflowing polymer is taken away at the same time, reducing the labor intensity of workers and reducing the existing seal. Reduce the cost of edge tape, solve appearance problems such as burrs, and achieve the requirement of uniform edge thickness of double-glass modules.

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...
