Background
With the cost reduction and efficiency improvement of photovoltaic modules and the development of high-efficiency photovoltaic modules in recent years, the amount of white EVA (ethylene vinyl acetate) packaging adhesive films for packaging the photovoltaic modules is increased year by year. The white EVA packaging adhesive film belongs to an upgrading and updating product of a common transparent EVA packaging adhesive film, can change the reflection path of light, and increases the absorption and utilization of the photovoltaic module on the cell gap light and the long-wave band light. The white EVA adhesive film in the single-glass assembly can increase the power gain of the assembly by 1-3W; in the dual glass assembly, the power gain can reach 2-5W.
The white EVA adhesive film is prepared by mixing the white EVA adhesive film with EVA particles and an auxiliary agent in proportion. In consideration of processing cost, the content of the titanium dioxide in the color master batch on the market is between 40 and 60 percent. Because the addition amount of the titanium dioxide in the color master batch is large, and in order to have a good reflection effect, the particle size of the selected titanium dioxide is small, the particle size is between 0.2 and 0.3 mu m, the specific surface area is large, the surface energy is high, the agglomeration or bridging phenomenon is easy to occur in the processing process, so that the titanium dioxide in the color master batch is not uniformly dispersed, the material accumulation phenomenon is easy to occur at a die head in the extrusion and casting process of the white EVA adhesive film, the caking problem is easy to occur in the extrusion process of the adhesive film, the yield of the white EVA adhesive film is reduced, the joint rate of the adhesive film is increased, and the production efficiency is reduced. Moreover, the cell of the photovoltaic module is very thin, and if the white EVA adhesive film is caked, the cell is easily hidden and cracked during module packaging.
Therefore, the caking phenomenon of the white packaging adhesive film for the photovoltaic module is reduced, and the method has important significance for improving the quality of the photovoltaic module and promoting the development of the photovoltaic industry.
