Document Type and Number:
Japanese Patent JP2018167524
Kind Code:
A
Abstract:
To provide a glass substrate protective film which easily removes fine air bubbles remaining between a cell glass substrate and the glass substrate protective film after integration as a solar cell module, and can exhibit excellent adhesion with the cell glass substrate and high adhesion durability.SOLUTION: A glass substrate protective film 1 has a base material layer 11 and an adhesion reinforcing layer 12 arranged on the outermost surface, where the base material layer 11 contains a polyester resin or a fluorine resin as a base resin, the adhesion reinforcing layer 12 contains a polyethylene resin having a melting point of 90°C or higher and 140°C or lower as a base resin, a silane component constituted by an appropriate amount of a grafted silane component and a non-grafted silane component is contained in the total resin component of the adhesion reinforcing layer, and a coefficient of dynamic friction at a resin temperature of 90°C on the surface of the adhesion reinforcing layer 12 is 0.50 or less.SELECTED DRAWING: Figure 1
