COMPOSITION FOR MOLDING RIGID POLYURETHANE FOAM AND MANUFACTURING PROCESS OF RIGID POLYURETHANE FOAM USING THE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a composition for molding a rigid polyurethane foam which is an open cell rigid polyurethane foam with a closed cell ratio of 0-75% using only water as a foaming agent and where scorching in the foam is easily improved with a simple method and its manufacturing process. SOLUTION: A compound having an unsaturated bond and a carbonyl group adjacent to each other is used as a modifying additive in an amount of 0.01-20 pts.mass to 100 pts.mass of an organic polyisocyanate or a polyol.
