摘要:

PROBLEM TO BE SOLVED: To provide a method for producing a polyurethane laminated body where a foam sheet and a polyurethane film are joined without using an adhesive, and to provide a polyurethane laminated body produced by this method.

SOLUTION: In the method for producing a polyurethane laminated body, a sheet composed of a polyurethane foam obtained by reacting foam raw materials comprising an isocyanate-terminal prepolymer and water which is excessive based on an isocyanate group, and foaming the same, and a polyether based thermoplastic polyurethane film whose one face is pasted with a supporting material are laminated in such a manner that one face of the sheet and the other face of the film are confronted, thereafter, heating is performed from the side of the supporting material in such a manner that the temperature of the film reaches the one lower by 20°C than the temperature at which the film is fused to the one higher than by 20°C, the same is pressurized, is joined, and is then cooled, and subsequently, the supporting material is removed.
