The present invention is a polyurethane foam having a mechanical property such as hardness and stiffness similar to that of a high-temperature treated wood, a small deformation such as cracking or warping without moisture, and capable of maintaining proper anti-elasticity when an external force is applied, and a method of manufacturing the same. It is about. Polyurethane foam according to the present invention, a resin mixture formed by mixing and stirring polypropylene glycol, acrylate-based polymer, silica, nucleating agent, foam stabilizer, catalyst, foaming agent, coloring agent and the like; It is characterized in that the prepolymer type isocyanate reacting the polyol and the amine polyol with the isocyanate and the polydiphenylmethane diisocyanate are mixed and stirred to simultaneously blow and foam and cure. |
