This invention relates to an intermediate sheet for coated urethane resin floors that can be obtained from. In recent years, tennis courts, playgrounds, etc.
Painting in which urethane resin is applied directly onto concrete surfaces Urethane resin is applied to floors and rooftops to make them waterproof. These coated urethane resin floors are coated with three types of urethane resin to give them cushioning properties.
The process must be repeated ~4 times, requiring a great deal of effort and time. In addition, since the urethane resin layer is formed directly on the concrete surface, when the moisture in the concrete expands and turns into water vapor due to the heating of the outside temperature, there is no place for the generated water vapor to escape, and this will cause the concrete to evaporate. This causes delamination between the surface and the painted urethane resin layer, causing unevenness on the floor surface.Furthermore, if the concrete cracks, the painted urethane resin layer will also crack and will no longer function as a waterproofing agent. have.

A covering synthetic resin layer made of a thermoplastic synthetic resin layer having adhesive properties to resin may be provided. The coating synthetic resin layer is intended to increase the adhesive strength between the coated urethane resin and the coated urethane resin formed on the upper surface of the coated urethane resin floor intermediate sheet, and is made of a thermoplastic synthetic resin that has adhesive properties to the coated urethane resin. For example, urethane-based, polyester-based,
It is made of synthetic resin such as polyethyleneimine and has a thickness of approximately 0.01 to 5 μm on the surface treated with corona discharge.

得る構造とすることができる。 Next, FIG. 2 shows a painted urethane resin floor formed using the intermediate sheet 1 for painted urethane resin floors of the present invention. The painted urethane resin floor intermediate sheet 1 of the present invention is laminated to the base concrete 8, and the urethane resin 9 is further applied onto the painted urethane resin floor intermediate sheet 1. Here, the painted urethane resin floor intermediate sheet 1 is applied to the base concrete 8.
When bonding to the concrete 8, the adhesion between the underlying concrete 8 and the painted urethane resin floor intermediate sheet 1 can be improved by coating the concrete 8 surface with a urethane-based moisture-curing type brimer and applying brimer treatment. In the case where 8 concrete surfaces are treated with brimer, the 8 concrete surfaces are partially coated with brimer to create areas where brimer is not applied, and the painted urethane resin floor is partially unadhesive. Use intermediate sheet 1 for
It is also possible to make it easier to degas gas such as steam from the base by laminating the painted urethane resin floor intermediate sheet 1 to the concrete 8 so that a part of the adhesive layer does not overlap with the brimer application area. be. For example, as shown in Figures 3 and 4, a brimer coat section 10 of approximately 1 m width is provided on 8 concrete surfaces via a non-brimer coat section 11 of approximately 10 to 50 m/m width, and on top of that, as shown in Figures 5 and 6. 10 to 30 mm along the flow direction of the sheet on two sides of the nonwoven fabric.
By pasting the painted urethane resin intermediate sheet 1 for flooring provided with the adhesive layer 5 with a width of 200 to 500 mm through the non-adhesive part 7 as shown in Figure 7, the 8 concrete surfaces are free of brimer and adhesive. Area 12
It is possible to form a structure in which a gas such as water vapor can be degassed from this region.
