Title:
RIBBON CARRIER FILM, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/252755
Kind Code:
A1
Abstract:
Disclosed are a ribbon carrier film, a preparation method therefor, and an application thereof, the ribbon carrier film comprising a pre-crosslinked layer and a bonding layer, the matrix resin of the pre-crosslinked layer and the bonding layer being the same, the matrix resin being one or more of ethylene-vinyl acetate copolymer, polyolefin elastomer, ethylene acrylic acid copolymer, or ethyl methacrylate, the pre-crosslinking degree of the pre-crosslinked layer being 30-80%, the pre-crosslinking degree of the bonding layer being ≤1% and, after the ribbon carrier film is prepared into a photovoltaic module, the cross-linking degree of the bonding layer being 50-90%. The ribbon carrier film of the present application can be fused into one after being laminated, has no risk of delamination failure, and can avoid the risk of failure caused by the hot spot effect during use of the component; the overall material transmittance is high and haze is low, and the bonding layer reacts chemically during the process of being laminated with a battery plate, thereby increasing the bonding force between the carrier film and the battery plate, and further improving the long-term reliability of the product.
