摘要:
A multi-layered film, a backsheet for photovoltaic modules, a method of manufacturing the same, and a photovoltaic module are provided. The multi-layered film can be configured so that a resin layer including a fluorine-based polymer and an oxazoline group-containing polymer is formed on a substrate. As a result, the resin layer including the fluorine-based polymer can have excellent durability and weather resistance, and show high interfacial adhesive strength to the substrate. During the preparation of the multi-layered films, a drying process can also be performed at a relatively low temperature, so that the manufacturing costs can be reduced and the quality of the product can be prevented from being deteriorated by thermal deformation or thermal shock. The multi-layered film may be effectively used as the backsheet in a variety of photovoltaic modules.

A process for forming a multilayer film includes coating a polymeric substrate film with a liquid fluoropolymer coating. The liquid fluoropolymer coating includes a fluoropolymer, solvent, a compatible cross-linkable adhesive polymer, and a cross-linking agent. The process further includes cross-linking the compatible cross-linkable adhesive polymer to form a cross-linked polymer network in the fluoropolymer coating, removing the solvent from the fluoropolymer coating, and adhering the fluoropolymer coating to the polymeric substrate film. A liquid fluoropolymer coating composition includes a fluoropolymer selected from homopolymers and copolymers of vinyl fluoride and homopolymers and copolymers of vinylidene fluoride, solvent, a compatible cross-linkable adhesive polymer, and a cross-linking agent. A fluoropolymer coated film includes a polymeric substrate film and a fluoropolymer coating on the polymeric substrate film. The fluoropolymer coating includes a fluoropolymer and a compatible cross-linked adhesive polymer.

A liquid fluoropolymer coating composition and a process for using the composition to make fluoropolymer coated polymeric substrates. The liquid fluoropolymer composition comprises fluoropolymer selected from homopolymers and copolymers of vinyl fluoride and homopolymers and copolymers of vinylidene fluoride polymer, solvent, and compatible adhesive polymer comprising functional groups selected from carboxylic acid, sulfonic acid, aziridine, amine, isocyanate, melamine, epoxy, hydroxy, anhydride and mixtures thereof. In the process, the composition is applied to a polymeric substrate comprising functional groups on its surface that interact with said compatible adhesive polymer to promote bonding of said fluoropolymer coating to said substrate. The solvent is removed from the coating composition applied to the substrate to form a fluoropolymer coating on the substrate.

An ink for a piezoelectric driving-type inkjet for printing on a resin-based ink receiving layer (7) formed on one surface of a reflection-type display (20) contains 30% by weight to 75% by weight of a solvent which hardly dissolves the ink receiving layer and 3% by weight to 30% by weight of an alcohol-based solvent which easily dissolves the ink receiving layer.
摘要:
Une composition d'enduction liquide contient une résine de fluorure de polyvinyl. Cette résine est dispersée sous forme particulaire dans un liquide organique, de préférence un carbonate d'alcène inférieur possédant une action de solvatation latente sur elle, de concert avec un tensio-actif fluoré et un stabilisateur organométallique contenant au moins un métal sélectionné parmi l'étain, l'antimoine, le barium, le cadmium, le zinc et le calcium. Cette composition permet l'application de revêtements à base de fluorure de polyvinyl par des procédés d'enduction liquide classiques plutôt que par laminage sous forme de film utilié jusqu'à présent.
