| titleOfInvention | Rigid polyurethane foam |
| abstract | PROBLEM TO BE SOLVED: To provide a rigid polyurethane foam which has good flame retardancy while using an alternative foaming agent, and is excellent in mechanical strength and dimensional stability. SOLUTION: A rigid polyurethane foam obtained by mixing and foaming a mixture of a polyisocyanate component, a polyol component, a foaming agent, a catalyst, a foam stabilizer, and other auxiliaries. The polyol component comprises one or more polybasic acid components selected from the group consisting of m-phthalic acid, p-phthalic acid, trimellitic acid and derivatives thereof, and a hydroxy compound component, and the hydroxy compound component Wherein the proportion of the tri- or higher functional hydroxy compound component is 5% by weight or more, and the polyester polyol compound obtained by subjecting the polybasic acid component and the hydroxy compound component to an esterification reaction contains 3% in the polyol component. % By weight or more. |
