The invention discloses a solar panel back film and a technique for manufacturing the same. The back film comprises a PET film substrate with thickness of between 100 and 350 micrometers, wherein, fluoropolymer coatings with thickness of between 15 and 30 micrometers are coated on both sides of the substrate; an adhesive layer with thickness of between 0.5 and 5 micrometers is coated on the fluoropolymer coating on one side; the fluoropolymer coatings are obtained by direct coating of mixed latex which is obtained through mixture of various raw material compositions according to the mixture ratio and subsequent grinding treatment on the PET film substrate; the compositions by mass ratio of the raw materials of the fluoropolymer coatings are 30 to 55 percent of fluoride coating materials, 20 to 40 percent of solvent, 2 to 6 percent of cross-linking agent and curing agent and 15 to 40 percent of filling. The technique greatly improves the bonding strength between a back film layer and alayer, improves the ageing resistance, the weathering resistance of products, simultaneously improves the insulativity and the vapor permeability resistance due to the design of a multilayered structure and also can design and modify the performance and the appearance of the products as required.

The invention relates to the technical field of an injection mould, and in particular relates to a rotating laminated type injection mould and an injection method using the same. The mould comprises a fixed mould main body and a movable mould main body, wherein the fixed mould main body comprises a fixed mould plate and a fixed mould chamber, the movable mould main body comprises a movable mould plate, an ejection mechanism and a movable mould chamber, the movable mould chamber is coupled with a rotating disk, one side of the mould is provided with a driving device which drives the rotating disk to rotate, the rotating disk is annularly provided with at least two embedding pieces which are set according to the thickness of a product, and the fixed mould chamber is provided with cavities which are matched with the embedding pieces. As the rotating disk rotates, the embedding pieces arranged at the rotating disk and the cavities arranged at the fixed mould chamber are closed, glued and cooled to be formed and opened, and the transparent product with the special thickness is divided to be subjected to alternated type or laminated type injection at least twice. The invention is reasonable in structure, the size of a mould blank is reduced, the indentation on the surface of the transparent product with the special thickness is controlled, the easily generated air bubble of an inner core is avoided, the injection period is shortened, and the production cost is reduced.
