It is manufactured by bonding and integrating by curing.
- the EVA film contains vinyl acetate as a component thereof, it tends to be hydrolyzed with time due to permeation of moisture or water at a high temperature to produce acetic acid. Yes (and also originally containing trace amounts of acetic acid), it was found that such acetic acid accelerates the generation of ⁇ by contact with internal conductors and electrodes.
- Such EVA films are also used for laminated glass such as automobile windshields.
- Laminated glass generally has a structure in which a transparent adhesive layer (intermediate film) made of an organic resin is sandwiched between glass plates (or between a glass and a plastic plate). In recent years, laminated glass has been deposited between the glass and the EVA film.
- Laminated glass for heat ray reflection with a metal film inserted has also been increasingly used.

- the amount of the crosslinking agent in the present invention is particularly preferably 1% by mass or less. This is because if too much cross-linking agent is added, the curing time is shortened, but air bubbles (possibly derived from acetic acid) are likely to be generated in the EVA, which impairs transparency. .

These amounts mainly vary depending on the vinylinole acetate content of the ethylene Z vinyl acetate copolymer. Use in such a range is generally advantageous for improving transparency and suppressing generation of acetic acid.
- the vinyl acetate content of the ethylenenoacetate butyl copolymer is 25 to 29 mass. / 0 , especially 25-27 mass. / 0 is preferred. Acetic acid generation is suppressed and transparency can be ensured.
- the haze is preferably 3 or less (especially 1 or less).
- the crosslinking aid is triaryl isocyanurate.
- the cross-linking agent is preferably 2,5-dimethyl-2,5-bis (t-butylperoxy) hexane, 1,1-bis (t-butylperoxy) -13,3,5-trimethinolecyclohexane.
- the film of the present invention when used as a sealing film for a solar cell, laminated glass, or the like, contains a benzotriazole-based compound in order to prevent the occurrence of corrosion such as ⁇ against the metal inside the film. Is preferred.
- the resin film according to the present invention has a low acetic acid content and its generation with time is small, so that when this film comes into contact with a metal, it is almost impossible to corrode the metal. Not really. Furthermore, the resin film of the present invention has low haze and high transparency, and can be advantageously used in applications where high transparency is required to be maintained without corroding metals. .
- the resin film of the present invention when used as a sealing film for a silicon power generation element of a solar cell, the generation of internal conductors and electrodes due to moisture or water permeation at high temperatures or the like can be reduced to an acetate. It can be prevented by suppressing the occurrence of Also, in a laminated glass for heat ray reflection in which a vapor-deposited metal film is inserted between the glass and the EVA film, it is possible to suppress the generation of the color of the metal film as described above. Therefore, it can be used particularly advantageously for these applications. Further, the resin film of the present invention can be advantageously used in any field where the film comes into contact with metal. Brief Description of Drawings
- FIG. 2 is a cross-sectional view showing a basic configuration when the resin film of the present invention is used for a solar cell.
- FIG. 3 is a cross-sectional view showing a basic configuration when the resin film of the present invention is used for a laminated glass.
- the resin film of the present invention is a film containing an ethylene-vinyl acetate copolymer as a main component and in which the generation of acid is sufficiently suppressed.
- the resin film of the present invention suppresses the generation of acetic acid, when used as a sealing film for a silicon power generation element of a solar cell, when the resin film of the present invention is used at a high temperature or the like, the internal conductive wires and electrodes due to moisture or water permeation. Can be prevented from occurring. Further, even in a laminated glass for heat ray reflection in which a vapor-deposited metal film is inserted between the glass and the EVA film, the generation of the color of the metal film can be suppressed in the same manner as described above. Further, the resin film of the present invention can be advantageously used in any field where the film is brought into contact with a metal.
- the resin film of the present invention preferably contains an ethylenenoacetate butyl copolymer as a main component, and further contains additives such as a crosslinking agent, a crosslinking aid, and a silane coupling agent.
