Low-precipitation anti-sliding polyolefin photovoltaic packaging adhesive film and preparation method thereof

The invention belongs to the technical field of packaging adhesive films, and particularly relates to a low-precipitation anti-sliding polyolefin photovoltaic packaging adhesive film and a preparation method thereof.The preparation method comprises the following steps that S1, hydroxylation modification is conducted on a porous nanometer material, and then crosslinking is conducted to prepare an acrylic acid grafted nanometer material; s2, carrying out a reaction on the single-layer graphene and an ionic surfactant to prepare a surfactant modified single-layer graphene material; s3, polyolefin resin, the acrylic acid grafted nano material and the surfactant modified single-layer graphene material are blended, grafting granulation is performed through a granulator, cooling and pelletizing are performed, and modified polyolefin master batches are obtained; and S4, blending the modified polyolefin master batch and the base material in proportion, adding an initiator, a light stabilizer, an antioxidant and a sila
