no. 1 approach

[0032] First, a vinylidene fluoride resin film (hereinafter also simply referred to as a resin film) according to a first embodiment of the present invention will be described. The resin film of this embodiment contains at least a resin component composed of a vinylidene fluoride resin and a methacrylate resin, titanium oxide, and a fatty acid ester of polyethylene glycol and / or its derivatives.

[0033] In addition, the titanium oxide compounded in the resin film of this embodiment is surface-treated with alumina and silica, and their total adhesion amount is 5 to 11 mass % with respect to the total mass of titanium oxide. In addition, the "total mass of titanium oxide" referred to here is a mass including alumina and silica adhered to the surface. Hereinafter, each component which comprises the resin film of this embodiment is demonstrated.

no. 2 approach

[0067] Next, a vinylidene fluoride-based resin film according to a second embodiment of the present invention will be described. The resin film of this embodiment is a multilayer film having two or more layers with different compositions, and contains vinylidene fluoride resin, methacrylate resin, and aluminum oxide and Silicon surface-treated titanium oxide, and fatty acid esters of polyethylene glycol and / or derivatives thereof.

[0068] [Resin composition mixing ratio]

[0069]The resin component in the resin film of the present embodiment is composed of the aforementioned vinylidene fluoride resin and methacrylate resin, and the compounding ratio thereof is vinylidene fluoride resin:methacrylate resin= 70:30 to 95:5, in the back layer, vinylidene fluoride resin:methacrylate resin=5:95 to 45:55 in terms of mass ratio. That is, in the resin film of this embodiment, the compounding ratio of a vinylidene fluoride resin and a methacrylate resin differs between a surface layer...

no. 1 Embodiment

[0091] The effects of the present invention will be described below with examples and comparative examples of the present invention. First, as an example of the first embodiment of the present invention, the resin films of Examples 1 to 8 were produced from the resin compositions of the compositions shown in Table 1 below, and the pigment dispersibility and thermal stability thereof were evaluated.

[0092]

[0093] Specifically, first, vinylidene fluoride resin, methacrylate resin, titanium oxide, and fatty acid ester of polyethylene glycol (PEG) were mixed with a tumbler according to the compounding ratio shown in Table 1 above. blend. Then, by diameter A twin-screw extruder was used for kneading to obtain a compound (resin composition). Next, use the diameter The single-screw extruder was equipped with a film-making machine with a slit of 0.4mm and a width of 400mm with a hanger-type die to produce a resin film with the thickness shown in Table 1 above.

Abstract

Disclosed is a vinylidene fluoride-based resin film which is highly adhesive to a substrate material, achieves good dispersibility even in the case of containing a pigment in a large amount and is highly heat-stable in molding. Specifically disclosed is a vinylidene fluoride-based resin film which is produced by adding, to resin components comprising a vinylidene fluoride resin and a methacrylate resin, titanium oxide being surface-treated with alumina and silica and a fatty acid ester of polyethylene glycol and / or a derivative of the same, each in a definite amount. Specifically disclosed is another vinylidene fluoride-based resin film comprising at least a top face layer and a back face layer each having the aforesaid composition, wherein the composition ratio of the vinylidene fluoride resin to the methacrylate resin in the top face layer is controlled in the range of 70:30 to 95:5 in terms of mass ratio, and the composition ratio of the vinylidene fluoride resin to the methacrylate resin in the back face layer is controlled in the range of 5:95 to 45:55 in terms of mass ratio. In either case, the total amount of alumina and silica attached to titanium oxide is controlled in the range of 5 to 11% by mass based on the total mass of titanium oxide.

Description

technical field [0001] The present invention relates to a vinylidene fluoride resin film. More specifically, the present invention relates to a vinylidene fluoride resin film in which a methacrylate resin, an inorganic pigment, and the like are blended with a vinylidene fluoride resin. Background technique [0002] Coating or laminating the surfaces of plastic sheets, metal sheets, and other various substrates used in interior and exterior parts of buildings for the purpose of protecting substrates, improving weather resistance, and imparting decoration and aesthetics Resin film. As a resin film used for such an application, a fluorine-based resin film excellent in weather resistance is mainly used, and in particular, a vinylidene fluoride-based resin film is often used. [0003] The vinylidene fluoride-based resin film is not limited to the aforementioned uses, but is also used for wallpaper, wall coverings, interior and exterior decoration materials for vehicles, elevato...
