METHOD FOR PRODUCING POLYURETHANE FOAM
[Problem] It is an object of the present invention to provide a method for producing a polyurethane foam in which the same polyurethane foam stock solution can be used throughout the year without adjusting reactivity by, for example, changing the amount of a catalyst.[Solution] The present invention is a method for producing a polyurethane foam, wherein the method comprises a step of spraying a polyurethane foam stock solution comprising a polyisocyanate component and a polyol component in a mist form by using compressed gas, in which the compressed gas in the step is heated and kept at a temperature of not less than 40°C.
