<P>PROBLEM TO BE SOLVED: To provide a re-release sheet for a floor in which peeling, warping, floor-squeak and the like of a floor finishing material that are problems in a conventional floor work method are prevented from occurring, a re-release property in renewing the floor finishing material is sufficient, exchange workability is excellent, generation of harmful gas such as formaldehyde is also prevented, further, even in long-term use under a high-temperature environment, the re-release property in renewing the floor finishing material is sufficient and the exchange workability is excellent, and a construction method of a floor finishing material using the same. <P>SOLUTION: A re-release sheet 10 for a floor is configured by forming an adhesive layer 12 at a rear side of a sheet-like base material layer 11 interposed between a first plastic-based floor tile 18 which is provided on a floor surface 17, and a floor finishing material 19. The adhesive layer contains synthetic resin emulsion in 5 to 90 pts.mass with respect to natural rubber latex in 100 pts.mass. A glass transition temperature of synthetic resin emulsion is -70°C to -15°C, and thickness of the adhesive layer is 50 to 150 μm. <P>COPYRIGHT: (C)2013,JPO&INPIT |
