Problems solved by technology

The high-temperature-resistant acrylic pressure-sensitive adhesive invented in Chinese patent CN106589434A has good high-temperature resistance, but the Tg is relatively high, and the initial adhesion of the adhesive tape is poor when the temperature is low in winter. High price and high production cost pressure are not conducive to large-scale production

Abstract

The invention belongs to the technical field of solar double-glass photovoltaic modules and in particular relates to a viscidity-reducing adhesive tape for lamination edge seal of a solar double-glassphotovoltaic module and a preparation method of the viscidity-reducing adhesive tape. The viscidity-reducing adhesive tape adopts a flexible substrate, the used composite membrane is not needed to bereleased, the prepared viscidity-reducing adhesive tape for the lamination edge seal of the solar double-glass photovoltaic module is not cross-linked at normal temperature, high in initial viscosityand good in compliancy, no residual adhesives exist when the adhesive tape is stripped after heating lamination, the adhesive tape is easy to strip and incapable of breaking, and the problem that theadhesive tape is easy to warp during construction under a low-temperature condition is solved. The adhesive tape disclosed by the invention has no burrs when being processed and slit, and the viscidity of the adhesive tape is reduced when the adhesive tape is stripped after high-temperature lamination, so that the adhesive tape is relatively easy to strip, no residual adhesives exist, and the condition of breaking can be avoided; and compared with an ordinary high-temperature-resistant silica gel adhesive tape, the viscidity-reducing adhesive tape is capable of reducing the production cost and increasing the production efficiency.

Description

technical field [0001] The invention belongs to the technical field of solar double-glass photovoltaic modules, and in particular relates to a solar double-glass photovoltaic module lamination edge-sealing adhesive tape and a preparation method thereof. Background technique [0002] In the production process of photovoltaic cell modules, the edge protection of the traditional lamination process is generally fixed by aluminum alloy frames, bonded and sealed with silica gel or adhesive tape, the process is complicated, and the production efficiency is low; double-glass modules use photovoltaic glass instead of the backplane, ultra-thin double-glass The advantages of module performance are prominent, and it has gradually become a mainstream product in the photovoltaic market. [0003] At present, the edge banding tape mentioned in the Chinese patent CN105957911A is an ordinary high-temperature silicone tape. With the price increase of silicon raw materials and environmental pro...
