| titleOfInvention | Method for producing rigid polyurethane foam |
| abstract | PROBLEM TO BE SOLVED: To provide a method for producing a rigid polyurethane foam capable of obtaining a foam excellent in heat insulation (thermal conductivity) without deteriorating the flammability (flame retardancy) of the rigid polyurethane foam. An active hydrogen-containing compound (A) having no vinyl polymerizable functional group, an organic polyisocyanate (B) and a vinyl polymerizable compound (Z) are added in the presence of a blowing agent (C) or a blowing agent ( C) and a method of producing a rigid polyurethane foam by reacting in the presence of a flame retardant (D), wherein (Z) has a specific vinyl polymerizable functional group, One or more vinyl polymerizable compounds having a specific composition having a concentration of 0.5 to 20 (mmol / g), and 50% by weight or more of (A) is an aromatic polyester polyol (A31), and a flame retardant A method for producing a rigid polyurethane foam, wherein the amount of (D) is less than 20% by weight based on the total weight of (A) and (Z).
