The invention discloses a method for preparing temperature-adjustable polyurethane foam, a phase change material and glass fiber powder are added into mold-outer paint, and are ground and mixed evenly by a ball mill, then the mixture is sprayed on the surface of foam by use of a spray gun, and the temperature-adjustable polyurethane foam can be obtained after a paint film is dried. The method is suitable for block-shaped foam, special-shaped molded foam parts directly prepared by a mold or various special-shaped molded foam parts prepared by cutting the block-shaped foam. 本发明公开了种制备可调温聚氨酯泡沫的方法，将相变材料和玻璃纤维粉加入到模外漆中，通过球磨机研磨混合均匀，然后用喷枪将混合物喷在泡沫表面上，待漆膜干燥后即得到可调温聚氨酯泡沫。该方法适于块状泡沫、通过模具直接制得异型模塑泡沫件或块状泡沫切割而成的各种异型泡沫件。
