[0018] Example 1
[0019] A solar cell encapsulation adhesive film, made by the following method: 100 parts by weight of matrix resin, 0.2 parts by weight of light conversion agent, 0.02 parts by weight of peroxide initiator, 0.8 parts by weight of crosslinking agent, 0.05 parts by weight Parts by weight of auxiliary crosslinking agent, 0.5 parts by weight of tackifier, 0.05 parts by weight of light stabilizer containing reactive groups, 0.05 parts by weight of antioxidant, 0.05 parts by weight of hydrophobic agent, 0.02 parts by weight of anti-oxidant After the acid agent is mixed evenly, it is granulated with a twin-screw extruder, and the finished single-screw extruder is extruded and cast to form a film.
[0020] Wherein, the crosslinking agent is tert-butylperoxycarbonate-2-ethylhexyl, and the auxiliary crosslinking agent is trimethylolpropane tri(methacrylate).
[0021] Among them, 4-acryloyloxy-2,2,6,6-tetramethylpiperidinol ester is selected as the light stabilizer co...
