  • Patent number: 7737192
    Abstract: A flexible polyurethane foam is produced by blending a polyurethane raw material containing a polyol, a polyisocyanate, a blowing agent, and a catalyst with an inorganic compound hydrate having a specific gravity of 1.5 to 4.0 and reacting the above polyurethane raw material to effect foaming and curing. The inorganic compound hydrate is preferably an iron sulfate hydrate, a calcium sulfate hydrate, or a magnesium sulfate hydrate. The above inorganic compound hydrate preferably has decomposition temperature of from 100 to 170° C. Then, an increase in exothermic temperature owing to the above foaming and curing is diminished by evaporation of water formed through decomposition of the above inorganic compound hydrate.

    Abstract: A polyurethane foam is obtained by reacting raw materials containing a polyisocyanate, a polyol, a water-absorbency-imparting agent, a catalyst, and a blowing agent, foaming the reaction mixture, and curing the foamed product. The polyol is a polyester polyol. The water-absorbency-imparting agent is a polyoxyalkylene compound having a molecular weight of 100 to 1000 and having a hydroxy group at an end of the molecular chain, or an alcohol with 1 to 8 carbon atoms. The amount of the water-absorbency-imparting agent is from 0.5 to 8 parts by mass per 100 parts by mass of the polyester polyol. The polyisocyanate is an aliphatic polyisocyanate, an alicyclic polyisocyanate, or an aromatic polyisocyanate in which the isocyanate groups are not directly attached to an aromatic ring. The foam has a water absorption ratio of 10 to 30 and a color difference ?YI of 7 or less. The time required until water dropped onto a surface of the foam is completely absorbed into the foam is 20 seconds or less.
