POLYOL COMPOSITION, FLAME-RETARDANT HARD POLYURETHANE FOAM AND METHOD FOR PRODUCING SAME

摘要

Provided are: a polyol composition which contains a flame retardant containing a prescribed phosphinic acid metal salt and/or a phosphate metal salt, said polyol composition making it possible to obtain a hard polyurethane foam which exhibits excellent flame retardancy and also being capable of suppressing particle precipitation and flocculation in a liquid in the case of said polyol composition and a starting material solution for a flame-retardant hard polyurethane foam; a flame-retardant hard polyurethane foam which uses the same; and a method for producing said foam. This polyol composition contains a polyol compound and a flame retardant. The polyol compound contains an aromatic polyester polyol and a Mannich polyol. The flame retardant contains one or more types of compound selected from the group consisting of a prescribed phosphinic acid metal salt and a phosphate metal salt.
