VAPOR BARRIER FILM, DISPERSION FOR VAPOR BARRIER FILM, METHOD FOR PRODUCING VAPOR BARRIER FILM, SOLAR CELL BACK SHEET, AND SOLAR CELL |
摘要 |
An object of the present invention is to provide a water vapor barrier film having good flexibility, good moisture resistance, and high mechanical strength. A further object of the present invention is to provide a dispersion for water vapor barrier films which is intended to be used to produce the water vapor barrier film, a method for producing the water vapor barrier film, a solar cell back sheet incorporating the water vapor barrier film, and a solar cell incorporating the water vapor barrier film or the solar cell back sheet. The present invention provided a water vapor barrier film containing: phyllosilicate mineral; and a synthetic resin, wherein the phyllosilicate mineral includes a non-swelling clay mineral and a swelling clay mineral, the phyllosilicate mineral is present in an amount of not less than 30% by weight and not more than 90% by weight of the total weight of the water vapor barrier film, and the water vapor barrier film has a water vapor permeability, measured at 40°C and 90%RH, of not more than 0.5 g/m 2 ·day. |
