Polyol composition for rigid polyurethane foam, composition for rigid polyurethane foam, and method for producing rigid polyurethane foam

摘要

The polyol composition for rigid polyurethane foam according to the present invention comprises a polyol compound, a blowing agent, a catalyst, and an acid ingredient and is for forming rigid polyurethane foam through mixing and reaction with a polyisocyanate ingredient, wherein the blowing agent comprises at least 1-chloro-3,3,3-trifluoropropene, the catalyst includes at least one catalyst selected from the group consisting of amine catalysts and metal catalysts, and the acid ingredient includes an organic acid. The polyol composition for rigid polyurethane foam has excellent storage stability. The present invention can provide a composition for rigid polyurethane foam and a production method for rigid polyurethane foam.
