The invention provides a water-blocking encapsulation adhesive film and a preparation method thereof. The water-blocking encapsulation adhesive film, in terms of mass percentage, comprises the following components: 75-95% of matrix material, 1-20% of modified sheet filler, 0.1-1% of cross-linking auxiliary, 0.2- of auxiliary cross-linking agent 1.5%, coupling agent 0.1-1%, antioxidant 0.1-1%, light stabilizer 0.1-0.5%, anti-PID masterbatch 1-5%. The water-blocking encapsulation adhesive film of the present invention can effectively avoid or slow down the problem of the water vapor transmission rate of the module, and further avoid or slow down the power attenuation of the cell. |
