Abstract

The invention belongs to the technical field of photovoltaic modules, and particularly relates to a method for improving the packaging fastness of a color layer and an adhesive film of a solar photovoltaic module. The method at least comprises the following steps: (1), spraying a bridging agent to an adhesive film layer or a color layer printed on glass, the adhesive film layer being a PVB adhesive film or an EVA adhesive film, and the bridging agent containing unsaturated double bonds; (2), carrying out hot air drying on the sprayed bridging agent; and (3), laminating the solar cell module, the adhesive film layer and the glass printed with the color layer in a laminating machine to obtain the solar cell module. According to the technical scheme, the inventor sprays the bridging agent on the adhesive film layer or the color layer printed on the glass, so that the bonding strength between the adhesive film layer and the color layer is greatly improved, the stability of the solar photovoltaic module is improved, the laminating time of the solar photovoltaic module is shortened, and the laminating cost is saved. The production efficiency of the solar photovoltaic module is improved, and the service life of the solar photovoltaic module is prolonged.

Description

Technical field[0001]The present invention belongs to the field of photovoltaic module, and more particularly to a method of improving the color layer of solar photovoltaic components and membrane packages.Background technique[0002]The existing color solar photovoltaic module generally uses the UV ink to print the pattern on the package glass, and then encapsulate the patterned encapsulating glass in the solar cell sheet by means of a patterned encapsulating glass. The main composition of the UV ink sold is acrylate. The existing use of the most widely used, low cost encapsulating film is a polyvinyl butyeldehyde film (PVB film) or ethylene-vinyl acetate copolymer film (EVA film). The polyvinyl alcohol is a thermoplastic resin film, which is produced by a polyvinyl butyral resin addition plasticizer, which has an advantage that can be recovered and reused. The ethylene-vinyl acetate copolymer film is a thermosetting film having better superiority in terms of adhesion, durability, an...
