Document Type and Number:
Japanese Patent JP2015221502
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for manufacturing a waterproof sheet that can easily produce a waterproof sheet inhibited from delamination between resin sheets and excellent in durability (repeated fatigue characteristics) and to provide a waterproof sheet that is inhibited from delamination between resin sheets and is excellent in durability (repeated fatigue characteristics).SOLUTION: The method for manufacturing a waterproof sheet has a molding step of molding a first resin sheet 1' and a second resin sheet 2' by extrusion molding a material including a resin and a pressure bonding step of sandwiching a fiber sheet composed of an aggregate of fibers between the first resin sheet 1' and the second resin sheet 2' at least one of which is in a molten state and pressure-bonding the first resin sheet 1' and the second resin sheet 2'.
