Abstract
PURPOSE: To prepare a polyurethane foam free from bottoming out and with an excellent cushioning property, by mixing a polyol, an org. isocyanate, a foaming agent, a catalyst and a metal powder and foaming the obtained mixture.
CONSTITUTION: To 100pts.wt. of urethane prepolymer obtained by heating and mixing a polyol and an org. isocyanate, above 10pts.wt. of a foaming agent, a catalyst and 20W300pts.wt. against 100pts.wt. of the polyol of a metal powder (e.g. iron powder, copper powder, or Al powder) with a particle size of 30W250μ are mixed and the obtained mixture is foamed. Thereby, mechanical properies and hysteresis of polyurethane foam can be improved and a cushion material for a furniture and a vehicle free from bottoming out is obtained.
