Beschreibung
Zusammenfassung:	The invention discloses a high-water blocking backplate material easy to clean for a large system photovoltaic module. The backplate material sequentially comprises an outer layer, a bonding layer, a base film layer and an inner layer, wherein the outer layer comprises fourth main body resin, a grafting auxiliary, an inorganic filler and a modified polymer brush grafted on a surface of the fourth main body resin. The local discharge voltage of the backplate material fabricated according to the invention is larger than 1,500V, the backplate material can be applied to the large system photovoltaic module, the power generation cost is reduced, and the power generation efficiency is improved; meanwhile, the backplate material is relatively low in moisture transmittance and can be used in a humid environment for a long time, and phenomena such as snail tracks and PID are improved; the outer surface of the backplate material also has a favorable function of being easy to clean, and the clean appearance can be maint
