Provided is a composition for a soft polyurethane foam, which is capable of producing a soft polyurethane foam having reduced odor and also having excellent curability. The composition for a soft polyurethane foam contains a polyether polyol (A), a reactive amine catalyst (B) having at least one amino group and at least one hydroxyl group, a non-reactive amine catalyst (C) having at least one amino group and not having a hydroxyl group, and a silicone foam stabilizer (D). When a total of 100 parts by mass of the polyol component having no amino group is used, the reactive amine catalyst (B) is 0.01 to 1.3 parts by mass, the non-reactive amine catalyst (C) is 0.01 to 0.20 parts by mass, and the silicone foam stabilizer (D) is 0.2 to 1.5 parts by mass. The silicone foam stabilizer (D) contains two silicone substances (D1 and D2) having different surface tensions.
提供了一种软质聚氨酯泡沫用组合物,其能够生产臭气减少的、还具有优异的固化性的软质聚氨酯泡沫。该软质聚氨酯泡沫用组合物包含聚醚多元醇(A)、具有至少一个氨基和至少一个羟基的反应型胺催化剂(B)、具有至少一个氨基且不具有羟基的非反应型胺催化剂(C)和有机硅稳泡剂(D)。使用合计100质量份不具有氨基的多元醇组分时,反应型胺催化剂(B)为0.01至1.3质量份,非反应型胺催化剂(C)为0.01至0.20质量份,并且有机硅稳泡剂(D)为0.2至1.5质量份。有机硅稳泡剂(D)含有表面张力不同的2种有机硅物质(Dl和D2)。
