▎ 摘 要
NOVELTY - Portable transparent conductive and thermal protective film comprises a release layer, a transparent pressure-sensitive adhesive layer and a transparent film layer are adjacently arranged in sequence from bottom to top. one side of the transparent film layer is fixedly connected with the transparent pressure-sensitive adhesive layer and the other side of the transparent film layer is provided with a transparent conductive coating. The transparent film layer is a polyvinyl chloride (PVC) calendered film. The nano-graphene is dispersed in polyvinyl chloride calendered film to form first network structure and transparent conductive coating on surface of the polyvinyl chloride calendered film has second network structure. The first network structure inside polyvinyl chloride calendering film and the second network structure on surface of the polyvinyl chloride calendering film form a spatial network structure of electric conduction and heat conduction. USE - Used as portable transparent conductive and thermal protective film. ADVANTAGE - The film: can transfer the heat in the preparation process of electronic component to the air to avoid damage to core component. DETAILED DESCRIPTION - Portable transparent conductive and thermal protective film comprises release layer, a transparent pressure-sensitive adhesive layer and a transparent film layer. The release layer, the transparent pressure-sensitive adhesive layer and the transparent film layer are adjacently arranged in sequence from bottom to top. one side of the transparent film layer is fixedly connected with the transparent pressure-sensitive adhesive layer and the other side of the transparent film layer is provided with a transparent conductive coating. The transparent conductive coating is a water-based acrylate coating containing silver nanowire. The transparent film layer is a polyvinyl chloride (PVC) calendered film including 100 pts. wt. polyvinyl chloride resin, 25-40 pts. wt. polymer polyester plasticizer, 2-4 pts. wt. powder calcium zinc stabilizer, 0.3-1 pts. wt. nano-graphene and 1-4 pts. wt. acrylate processing aid. The nano-graphene is uniformly dispersed in the polyvinyl chloride calendered film to form a first network structure and the transparent conductive coating on the surface of the polyvinyl chloride calendered film has a second network structure. The first network structure inside the polyvinyl chloride calendering film and the second network structure on the surface of the polyvinyl chloride calendering film form a spatial network structure of electric conduction and heat conduction. An INDEPENDENT CLAIM is also included for preparing portable transparent conductive and thermal protective film comprising (a) taking each component of corresponding weight based on the parts of polyvinyl chloride calendered film composition, mixing homogeneously nano graphene with polymer polyester type plasticizer to obtain the first mixture, uniformly mixing the first mixture with polyvinyl chloride resin, powder calcium zinc stabilizer and acrylate processing aid to obtain the second mixture, banburying the second mixture to obtain a pre-plasticized melt, refining, extruding, and calendering the melt to obtain a polyvinyl chloride calendered film with a first network structure, (b) using a printing roller with a mesh pattern, coating the water-based acrylate containing nano-silver wire on one side of the polyvinyl chloride calendered film by gravure printing, thus forming a transparent conductive coating with a second network structure on the surface of the polyvinyl chloride calendered film, where the first network structure inside the polyvinyl chloride calendering film and the second network structure on the surface of the polyvinyl chloride calendering film form a spatial network structure of electric conduction and heat conduction and (c) coating after the other side of the polyvinyl chloride calendered film with a transparent pressure-sensitive adhesive layer and covering the release paper on the transparent pressure-sensitive adhesive layer and pasting.
