Non-combustible film, dispersion liquid for non-combustible films, method for producing non-combustible film, solar cell back sheet, flexible board, and solar cell

Abstract

The present invention aims to provide a non-combustible film having excellent flexibility, excellent moisture resistance, and high mechanical strength. The present invention also aims to provide a dispersion liquid for non-combustible films which is used in production of the non-combustible film, a method for producing a non-combustible film using the above dispersion, and a solar cell back sheet and a flexible board each of which is formed from the above non-combustible film. The present invention further aims to provide a solar cell including the solar cell back sheet. The non-combustible film of the present invention includes a water-insoluble inorganic compound and a heat-resistant synthetic resin, the water-insoluble inorganic compound constituting from 30% by weight to 90% by weight inclusive of the total weight of the non-combustible film, the film exhibiting a flammability of VTM-0 in the UL-94 VTM test.
