Abstract
PURPOSE: To obtain the title mold foam for use as a cushioning material, by using a sucrose-containing polyether polyol as an initiator of polyol, a reaction accelerator of an aminoalkylene ether compound, and two kinds of foam stabilizers having high and low activities.
CONSTITUTION: In the production of a polyurethane foam from polyol, an organic isocyanate, foam stabilizers, a reaction accelerator, a blowing agent, etc. by molding, a polyether polyol containing not less than 10mol%, preferably not less than 15mol% of sucrose is used as an initiator of polyol. A reaction accelerator of an aminoalkylene ether compound, e.g., N-methylmorpholine, N-ethylmorpholine, a foam stabilizer having low activity, e.g., F-121, F-260, and that having high activity, e.g., F-122 are used together. Polyurethane mold foam obtained has no dry spot on its surface, but hardness and moldability are improved.
